## Architecture Overview

Clawncher v0.1.0 deploys tokens via approved Uniswap V4 infrastructure on Base. The Clawncher API handles all deployment complexity.

```
User calls ClawnchApiDeployer.deploy(options)
  1. SDK validates config and prepares deployment
  2. Token deployed via approved Uniswap V4 infrastructure
  3. Pool initialized with MEV protection and fee distribution
  4. Extensions execute (vault lockup, dev buy)
  5. Token is immediately tradeable on Uniswap
```

> **Note:** v0.1.0 uses approved Uniswap V4 infrastructure. Same Clawncher API, production-grade contracts.

**Contract relationships:**

## Smart Contracts

> **Note:** These are the approved v4 infrastructure contracts. Clawncher deploys tokens through these contracts via the SDK.

### ClawnchFactory

**Source**: `contracts/src/ClawnchFactory.sol`  
**Inherits**: `OwnerAdmins`, `ReentrancyGuard`, `IClawnch`

The factory is the main entry point for deploying tokens. It orchestrates token creation, pool initialization, LP position minting, MEV module setup, and extension execution.

**Constants:**
- `TOKEN_SUPPLY`: 100,000,000,000 tokens (100B with 18 decimals)
- `BPS`: 10,000 (basis points)
- `MAX_EXTENSIONS`: 10
- `MAX_EXTENSION_BPS`: 9,000 (90% max for extensions)

**Storage:**
| Slot | Variable | Type |
|------|----------|------|
| 0 | `_owner` | `address` |
| 1 | `admins` | `mapping(address => bool)` |
| 2 | `vaultExtension` | `address` |
| 3 | `teamFeeRecipient` | `address` |
| 3 | `deprecated` | `bool` (packed at offset 20) |
| 4 | `deploymentInfoForToken` | `mapping(address => DeploymentInfo)` |
| 5 | `enabledHooks` | `mapping(address => bool)` |
| 6 | `enabledLockers` | `mapping(address => mapping(address => bool))` |
| 7 | `enabledExtensions` | `mapping(address => bool)` |
| 8 | `enabledMevModules` | `mapping(address => bool)` |

**Key Functions:**

```solidity
// Deploy a token with full infrastructure (pool, LP, MEV, extensions)
function deployToken(DeploymentConfig memory config) external payable returns (address tokenAddress);

// Deploy a token with zero initial supply (cross-chain)
function deployTokenZeroSupply(TokenConfig memory config) external returns (address tokenAddress);

// Read deployment info for a token
function tokenDeploymentInfo(address token) external view returns (DeploymentInfo memory);

// Admin: enable/disable modules
function setHook(address hook, bool enabled) external onlyOwner;
function setLocker(address locker, address hook, bool enabled) external onlyOwner;
function setMevModule(address mevModule, bool enabled) external onlyOwner;
function setExtension(address extension, bool enabled) external onlyOwner;
function setVaultExtension(address vaultExtension) external onlyOwner;
function setTeamFeeRecipient(address recipient) external onlyOwner;
function setDeprecated(bool deprecated) external onlyOwner;
```

**Deployment Config Structs:**

```solidity
struct DeploymentConfig {
    TokenConfig tokenConfig;
    PoolConfig poolConfig;
    LockerConfig lockerConfig;
    MevModuleConfig mevModuleConfig;
    ExtensionConfig[] extensionConfigs;
}

struct TokenConfig {
    address tokenAdmin;
    string name;
    string symbol;
    bytes32 salt;          // CREATE2 salt (for vanity addresses)
    string image;

    uint256 originatingChainId;
}

struct PoolConfig {

    address pairedToken;   // Typically WETH
    int24 tickIfToken0IsClawnch;  // Starting price tick
    int24 tickSpacing;
    bytes poolData;        // Encoded PoolInitializationData
}

struct LockerConfig {
    address locker;
    address[] rewardAdmins;
    address[] rewardRecipients;
    uint16[] rewardBps;    // Must sum to 10000
    int24[] tickLower;
    int24[] tickUpper;
    uint16[] positionBps;  // Must sum to 10000
    bytes lockerData;      // Encoded LpFeeConversionInfo
}

struct MevModuleConfig {
    address mevModule;
    bytes mevModuleData;   // Encoded (startingFee, endingFee, secondsToDecay)
}

struct ExtensionConfig {
    address extension;
    uint256 msgValue;      // ETH to send (for dev buy)
    uint16 extensionBps;   // % of supply to allocate
    bytes extensionData;
}
```

**Events:**
```solidity
event TokenCreated(
    address msgSender,
    address indexed tokenAddress,
    address indexed tokenAdmin,
    string tokenImage,
    string tokenName,
    string tokenSymbol,

);
event SetDeprecated(bool deprecated);
event SetVaultExtension(address oldVaultExtension, address newVaultExtension);
event SetTeamFeeRecipient(address oldRecipient, address newRecipient);
```

### ClawnchToken

**Source**: `contracts/src/ClawnchToken.sol`

ERC-20 token deployed via CREATE2 from the factory. Includes on-chain metadata storage.

**Key Functions:**
```solidity
function admin() external view returns (address);
function originalAdmin() external view returns (address);
function imageUrl() external view returns (string memory);
function metadata() external view returns (string memory);
function context() external view returns (string memory);
function allData() external view returns (
    address originalAdmin, address admin, string memory image,
    string memory metadata, string memory context
);
function setAdmin(address newAdmin) external;        // Only current admin
function setImageUrl(string memory image) external;  // Only admin
```

---

### ClawnchHookStaticFeeV2

**Source**: `contracts/src/hooks/ClawnchHookStaticFeeV2.sol`  
**Inherits**: `ClawnchHookV2`

Uniswap V4 hook deployed via CREATE2. The address must end in `0x28CC` to encode the required hook permission bits:

- `BEFORE_INITIALIZE` (bit 13)
- `BEFORE_ADD_LIQUIDITY` (bit 11)
- `BEFORE_SWAP` (bit 7)
- `AFTER_SWAP` (bit 6)
- `BEFORE_SWAP_RETURNS_DELTA` (bit 3)
- `AFTER_SWAP_RETURNS_DELTA` (bit 2)

**Constructor:**
```solidity
constructor(
    IPoolManager poolManager_,
    address factory_,
    address poolExtensionAllowlist_,
    address weth_
)
```

**Key Functions:**
```solidity
// Pool initialization (called by factory via initializePool)
function initializePool(
    PoolKey memory poolKey,
    int24 startingTick,
    bytes calldata initData
) external returns (PoolKey memory);

// MEV module
function initializeMevModule(PoolKey calldata poolKey, bytes calldata data) external;
function mevModuleEnabled(PoolId poolId) external view returns (bool);
function poolCreationTimestamp(PoolId poolId) external view returns (uint256);
function MAX_MEV_MODULE_DELAY() external view returns (uint256); // 120 seconds

// Fee reads
function clawnchFee(PoolId poolId) external view returns (uint24);
function pairedFee(PoolId poolId) external view returns (uint24);
function protocolFee() external view returns (uint24); // Uses transient storage
```

**Protocol Fee (Transient Storage):**

The `protocolFee` is stored in EVM transient storage (Cancun `tstore`/`tload`) to prevent a shared-state vulnerability where reentrant fee collection swaps could read stale protocol fee values. Each `_setFee()` call writes to transient storage before `_afterSwap()` reads from it.

```solidity
bytes32 private constant PROTOCOL_FEE_SLOT = keccak256("clawncher.hook.protocolFee");

function _setProtocolFee(uint24 lpFee) internal {
    uint24 fee = uint24(uint256(lpFee) * PROTOCOL_FEE_NUMERATOR / uint128(FEE_DENOMINATOR));
    bytes32 slot = PROTOCOL_FEE_SLOT;
    assembly { tstore(slot, fee) }
}

function _getProtocolFee() internal view returns (uint24 fee) {
    bytes32 slot = PROTOCOL_FEE_SLOT;
    assembly { fee := tload(slot) }
}
```

### ClawnchLpLockerFeeConversion

**Source**: `contracts/src/lp-lockers/ClawnchLpLockerFeeConversion.sol`  
**Inherits**: `IClawnchLpLockerFeeConversion`, `ReentrancyGuard`, `Ownable`

Manages LP positions and distributes trading fees to reward recipients. Supports up to 7 recipients with configurable fee preferences (receive in token, WETH, or both).

**Constants:**
- `MAX_REWARD_PARTICIPANTS`: 7
- `MAX_LP_POSITIONS`: 7
- `BASIS_POINTS`: 10,000

**Immutables:**
- `positionManager`, `poolManager`, `permit2`, `feeLocker`, `universalRouter`, `factory`

**Key State:**
- `maxSlippageBps`: Slippage protection for fee conversion swaps (default 500 = 5%, max 5000 = 50%)

**Key Functions:**
```solidity
// Place liquidity for a newly deployed token (called by factory)
function placeLiquidity(
    IClawnch.LockerConfig memory lockerConfig,
    IClawnch.PoolConfig memory poolConfig,
    PoolKey memory poolKey,
    uint256 poolSupply,
    address token
) external onlyFactory returns (uint256 positionId);

// Collect and distribute fees (anyone can call)
function collectRewards(address token) external;
function collectRewardsWithoutUnlock(address token) external;

// Reward management (only reward admin for that index)
function updateRewardRecipient(address token, uint256 rewardIndex, address newRecipient) external;
function updateRewardAdmin(address token, uint256 rewardIndex, address newAdmin) external;
function updateFeePreference(address token, uint256 rewardIndex, FeeIn newPreference) external;

// Read reward info
function tokenRewards(address token) external view returns (TokenRewardInfo memory);
function feePreferences(address token, uint256 index) external view returns (FeeIn);

// Owner admin
function setMaxSlippageBps(uint16 bps) external onlyOwner;
function withdrawETH(address recipient) external onlyOwner;
function withdrawERC20(address token, address recipient) external onlyOwner;
```

**Fee Preference Enum:**
```solidity
enum FeeIn {
    Both,    // 0 - Receive in both tokens
    Paired,  // 1 - Receive in paired token (WETH)
    Clawnch  // 2 - Receive in the launched token
}
```

**Fee Collection Flow:**
1. `collectRewards` / `collectRewardsWithoutUnlock` called (by hook on every swap, or manually)
2. LP fees collected from all positions via PositionManager
3. For each fee token (token0, token1):
   - Recipients wanting the *other* token get their share swapped
   - Recipients wanting *this* token get direct distribution
4. All fees deposited into `ClawnchFeeLocker` for recipient claiming

---

### ClawnchLpLockerLib

**Source**: `contracts/src/lp-lockers/ClawnchLpLockerLib.sol`

External library containing swap logic for fee conversion when the pool is locked. Deployed as a separate contract and called via `delegatecall` from the locker.

```solidity
library ClawnchLpLockerLib {
    function uniSwapLocked(
        IPermit2 permit2,
        IUniversalRouter universalRouter,
        PoolKey memory poolKey,
        address tokenIn,
        address tokenOut,
        uint128 amountIn,
        uint16 maxSlippageBps
    ) public returns (uint256);
}
```

This was made external (from `internal`) to reduce `ClawnchLpLockerFeeConversion` bytecode from ~25.5KB to ~24.5KB, staying under the EVM 24,576-byte code size limit.

---

### ClawnchFeeLocker

**Source**: `contracts/src/ClawnchFeeLocker.sol`  
**Inherits**: `IClawnchFeeLocker`, `ReentrancyGuard`, `Ownable`

Escrow contract that holds accumulated LP fees per (recipient, token) pair. Recipients claim their fees from here.

```solidity
// Deposit fees (only allowed depositors - the LP locker)
function storeFees(address feeOwner, address token, uint256 amount) external;

// Claim fees (by the fee owner themselves)
function claim(address feeOwner, address token) external;

// Read available fees
function availableFees(address feeOwner, address token) external view returns (uint256);

// Admin
function addDepositor(address depositor) external onlyOwner;
```

---

### ClawnchMevDescendingFees

**Source**: `contracts/src/mev-modules/ClawnchMevDescendingFees.sol`

MEV protection module that implements a descending fee curve. At token launch, the swap fee starts high (default 80%) and decays linearly to a low fee (default 5%) over a configurable period (default 30 seconds). This prevents sandwich attacks and sniper bots from extracting value at launch.

**Key Functions:**
```solidity
// Initialize for a pool (called by hook)
function initialize(PoolKey calldata poolKey, bytes calldata data) external;

// Called before each swap to compute current fee
function beforeSwap(
    PoolKey calldata poolKey,
    SwapParams calldata swapParams,
    bool clawnchIsToken0,
    bytes calldata mevModuleSwapData
) external returns (bool disableMevModule);

// Read current fee for a pool
function getFee(PoolId poolId) external view returns (uint24);
```

**Fee Decay Formula:**
```
elapsed = block.timestamp - poolStartTime
if elapsed >= secondsToDecay + delayGuard:
    fee = endingFee  (MEV module disables itself)
else:
    fee = startingFee - (startingFee - endingFee) * elapsed / secondsToDecay
```

The `delayGuard` (1 second) ensures the boundary condition is handled correctly (>= instead of >).

**Errors:**
- `SameSecondAsDeployment()` - Cannot swap in the same second the pool was created
- `PoolAlreadyInitialized()` - Pool already has MEV config
- `TimeDecayLongerThanMaxMevDelay()` - Decay period exceeds hook's `MAX_MEV_MODULE_DELAY` (120s)

---

### ClawnchVault

**Source**: `contracts/src/extensions/ClawnchVault.sol`

Extension that allocates a percentage of token supply into a vault with lockup and optional vesting. Uses `SafeERC20` for all transfers.

```solidity
// Read allocation
function allocation(address token) external view returns (
    address token_, uint256 amountTotal, uint256 amountClaimed,
    uint256 lockupEndTime, uint256 vestingEndTime, address admin
);

// Claimable amount (respects lockup + linear vesting)
function amountAvailableToClaim(address token) external view returns (uint256);

// Claim vested tokens (only admin)
function claim(address token) external;

// Transfer admin (only current admin)
function editAllocationAdmin(address token, address newAdmin) external;
```

**Lockup + Vesting:**
- `lockupDuration`: Time before any tokens can be claimed (min 7 days)
- `vestingDuration`: Linear vesting period after lockup (0 = instant after lockup)
- Claimable: `(amountTotal * elapsed_since_lockup / vestingDuration) - amountClaimed`

---

### ClawncherAirdropV2

**Source**: `contracts/src/extensions/ClawncherAirdropV2.sol`

Extension for merkle-tree-based token airdrops with lockup and vesting.

---

### ClawncherUniv4EthDevBuy

**Source**: `contracts/src/extensions/ClawncherUniv4EthDevBuy.sol`

Extension that executes a token buy at launch using ETH. The purchased tokens are transferred immediately to the recipient. Requires sending ETH as `msg.value` in the deployment transaction.

---

### ClawncherVestedDevBuy

**Source**: `contracts/src/extensions/ClawncherVestedDevBuy.sol`

Extension that executes a token buy at launch using ETH, then holds the purchased tokens in a vesting schedule. Combines dev buy with lockup + linear vesting.

```solidity
// Read allocation
function allocation(address token) external view returns (...);
function amountAvailableToClaim(address token) external view returns (uint256);

// Claim vested tokens
function claim(address token) external;
function editAllocationAdmin(address token, address newAdmin) external;

import { baseSepolia } from 'viem/chains';

const account = privateKeyToAccount('0x...');
const wallet = createWalletClient({
  account,
  chain: baseSepolia,
  transport: http(),
});
const publicClient = createPublicClient({
  chain: baseSepolia,
  transport: http(),
});

const deployer = new ClawnchDeployer({
  wallet,
  publicClient,
  network: 'sepolia', // or 'mainnet'
});

// List all V3 positions for a wallet
const positions = await liquidity.v3GetPositionsForWallet(walletAddress);
// Returns: PositionInfo[]

// Get V3 positions filtered by a specific token
const filtered = await liquidity.getPositionsForToken(tokenAddress, walletAddress);

// Mint a new V3 position
const mint = await liquidity.v3MintPosition({
  token0: '0x...',
  token1: '0x...',
  fee: 3000,           // 0.3% fee tier
  tickLower: -887220,
  tickUpper: 887220,
  amount0Desired: parseEther('1000'),
  amount1Desired: parseEther('0.1'),
  recipient: account.address,  // optional, defaults to wallet
  deadline: 1200,              // optional, seconds from now (default: 20 min)
});
// Returns: MintResult { txHash, tokenId, amount0, amount1, liquidity, receipt }

// Add liquidity to existing position
const added = await liquidity.v3AddLiquidity(tokenId, {
  amount0Desired: parseEther('500'),
  amount1Desired: parseEther('0.05'),
});
// Returns: ModifyLiquidityResult { txHash, amount0, amount1, receipt }

// Remove liquidity (fractional: 0.0 to 1.0)
const removed = await liquidity.v3RemoveLiquidity(tokenId, {
  percentageToRemove: 0.5,   // 50%
  burnToken: false,           // burn NFT if removing 100%
});
// Returns: ModifyLiquidityResult { txHash, amount0, amount1, receipt }

// Collect unclaimed fees
const fees = await liquidity.v3CollectFees(tokenId, {
  recipient: account.address,  // optional

```

#### V4 Methods

```typescript
// Read V4 pool state
const state = await liquidity.v4GetPoolState(poolKey);

// Execute V4 PositionManager multicall (use with @uniswap/v4-sdk calldata)
const { txHash, receipt } = await liquidity.v4ExecuteMulticall(calldata, value);
```

> **Note:** V4 mint/add/remove operations require `@uniswap/v4-sdk` for proper action encoding. Use `V4PositionManager.addCallParameters()` to generate calldata, then pass it to `v4ExecuteMulticall()`.

---

### ClawnchApiDeployer

Deploy tokens through the Clawnch API as a verified agent. Tokens deployed this way receive a verified badge on the Clawnch launchpad and appear in the dashboard.

**Registration flow:**
1. `POST /api/agents/register` — submit agent info, receive ECDSA challenge
2. Sign challenge with wallet
3. `POST /api/agents/verify` — submit signature, receive API key

**Deploy flow:**
1. Request captcha challenge from API
2. Solve: read on-chain storage slot, sign message, compute keccak proof
3. Submit solution + deploy params — server burns $CLAWNCH, deploys token

```typescript
import { ClawnchApiDeployer } from '@clawnch/clawncher-sdk';

// One-time agent registration
const { apiKey } = await ClawnchApiDeployer.register({
  wallet,
  publicClient,
}, {
  name: 'MyAgent',
  wallet: account.address,
  description: 'An AI agent that launches tokens',
});

// Create deployer with API key
const apiDeployer = new ClawnchApiDeployer({
  apiKey,
  wallet,
  publicClient,
  apiBaseUrl: 'https://clawn.ch',  // default
});
```

#### Methods

```typescript
// Check agent status (balance, verification, launch count)
const status = await apiDeployer.getStatus();
// Returns: AgentStatus { agentId, name, wallet, verified, clawnchAllowance, clawnchBalance, launchCount, registeredAt }

// One-time $CLAWNCH approval for the Clawnch deployer
const approval = await apiDeployer.approveClawnch();
// Returns: ApprovalResult { txHash, spender, amount }

// Check current allowance
const allowance = await apiDeployer.getClawnchAllowance(spenderAddress);

// Check $CLAWNCH balance
const balance = await apiDeployer.getClawnchBalance();

// Deploy a token (handles captcha automatically)
const result = await apiDeployer.deploy({
  name: 'My Token',
  symbol: 'MYTKN',
  image: 'https://example.com/logo.png',          // optional
  description: 'A token launched by my agent',     // optional
  // All standard deploy options supported
});
// Returns: ApiDeployResponse { txHash, tokenAddress, ... }
```

**Requirements:**
- Agent wallet must hold >= 100 $CLAWNCH (`0xa1F72459dfA10BAD200Ac160eCd78C6b77a747be`)
- One-time ERC20 approval for the Clawnch deployer wallet
- Captcha must be solved within 5 seconds (handled automatically by SDK)

---

### ClawnchClient (API)

  moltbookKey: 'secret-key',     // optional, for authenticated ops
  timeout: 30000,                // default 30s
});
```

#### Methods

```typescript
// Tokens
const tokens = await client.getTokens();
const token = await client.getTokenBySymbol('MYTKN');

// Launches
const launches = await client.getLaunches({
  limit: 20, offset: 0, agent: 'agentName', source: 'moltbook'
});
const launch = await client.getLaunch('0xContractAddress...');

// Stats
const stats = await client.getStats();
// Returns: { totalTokens, totalVolume, clawnchPrice, clawnchMarketCap }

// Preview / validation
const preview = await client.preview('!clawnch\nname: Test\nsymbol: TST\n...');

### Wallet Management

The CLI includes encrypted wallet storage using AES-256-GCM with scrypt KDF. Wallets are stored in `~/.clawncher/wallets/` with file permissions 0o600.

**Security model:**
- Private keys encrypted at rest with user-chosen password
- scrypt KDF (N=2^18, r=8, p=1) for key derivation
- AES-256-GCM authenticated encryption
- Directory permissions 0o700, file permissions 0o600
- Keys only decrypted on-demand, never cached in memory
- Mnemonic phrases encrypted alongside private key for recovery

#### `clawncher wallet create <name>`

## Deployment Guide

### Prerequisites

- [Foundry](https://book.getfoundry.sh/) (forge, cast)
- Node.js >= 18
- Deployer wallet with ETH on Base

### Deploying Contracts

The deployment process has two phases: contract deployment and initialization.

**1. Deploy the external library first:**

```bash
source .env.clawncher
cd contracts

# Deploy ClawnchLpLockerLib
forge create src/lp-lockers/ClawnchLpLockerLib.sol:ClawnchLpLockerLib \
  --private-key $CLAWNCHER_DEPLOYER_PRIVATE_KEY \
  --rpc-url https://mainnet.base.org \
  --broadcast
```

**2. Get the hook init code hash (dry run without salt):**

```bash
PRIVATE_KEY=$CLAWNCHER_DEPLOYER_PRIVATE_KEY \
forge script script/DeployClawnchMainnet.s.sol \
  --rpc-url https://mainnet.base.org -vvv
```

This prints the init code hash needed for CREATE2 salt mining.

**3. Mine the hook salt:**

```bash
cast create2 --ends-with 28CC \
  --deployer 0x4e59b44847b379578588920cA78FbF26c0B4956C \
  --init-code-hash <HASH_FROM_STEP_2>
```

The hook address must end in `0x28CC` for the required Uniswap V4 permission bits.

**4. Deploy all contracts:**

```bash
PRIVATE_KEY=$CLAWNCHER_DEPLOYER_PRIVATE_KEY \
HOOK_SALT=<SALT_FROM_STEP_3> \
forge script script/DeployClawnchMainnet.s.sol \
  --rpc-url https://mainnet.base.org \
  --broadcast -vvv \
  --libraries src/lp-lockers/ClawnchLpLockerLib.sol:ClawnchLpLockerLib:<LIBRARY_ADDRESS>
```

### Initialization

After deployment, run the initialization script to enable all modules:

```bash
PRIVATE_KEY=$CLAWNCHER_DEPLOYER_PRIVATE_KEY \
FACTORY=0x... HOOK=0x... LOCKER=0x... MEV_MODULE=0x... \
VAULT=0x... AIRDROP_V2=0x... DEV_BUY=0x... VESTED_DEV_BUY=0x... \
POOL_EXTENSION_ALLOWLIST=0x... FEE_LOCKER=0x... \
TEAM_FEE_RECIPIENT=0x... \
forge script script/InitializeClawnchMainnet.s.sol \
  --rpc-url https://mainnet.base.org --broadcast -vvv
```

**Initialization steps (performed by the script):**
1. Enable hook in factory
2. Enable locker for hook in factory
3. Enable MEV module in factory
4. Enable extensions (vault, airdropV2, devBuy, vestedDevBuy) in factory
5. Enable extensions in pool extension allowlist
6. Set vault extension address in factory
7. Add locker as allowed depositor in fee locker
8. Set team fee recipient
9. Undeprecate factory (enable deployments)

### Building

```bash
# Build contracts (uses via_ir, slow)
cd contracts && forge build

# Run tests (64 tests)
cd contracts && forge test

# Build SDK + CLI
npm run build

# Publish
cd packages/sdk && npm publish --access public
cd packages/cli && npm publish --access public
```

**Foundry config** (`contracts/foundry.toml`):
- Solc: 0.8.28
- EVM: cancun (for transient storage)
- Optimizer: enabled, 1 run, via_ir

## Fee Structure

Every swap through a Clawncher pool incurs a **1% LP Rewards** (configurable, default 10000 pips).

**Fee Distribution:**
- **80% to deployer** (or configured reward recipients)
- **20% protocol** (collected via platform infrastructure)

The deployer's 80% can be split among up to 7 reward recipients, each with configurable fee preferences:
- **Clawnch**: Receive fees in the launched token (default)
- **Paired**: Receive fees in WETH
- **Both**: Receive fees as-is (no conversion)

Fee conversion swaps include slippage protection (default 5%, configurable by locker owner up to 50%).

**Fee Collection Flow:**
1. On every swap, the hook calls `collectRewardsWithoutUnlock` on the locker
2. LP fees are collected from all Uniswap V4 positions
3. Fees are split per recipient based on their `rewardBps`
4. Fee conversions are performed (token ↔ WETH swaps as needed)
5. Fees are deposited into `ClawnchFeeLocker`
6. Recipients claim from `ClawnchFeeLocker` at their convenience

---

## MEV Protection

Clawncher uses a descending fee curve to protect against MEV attacks at token launch.

**Default Configuration:**
- Starting fee: **80%** (800,000 pips)
- Ending fee: **5%** (50,000 pips)
- Decay period: **30 seconds**

**How it works:**
1. At `t=0` (token deployment), the swap fee is 80%
2. The fee decays linearly: at `t=15s` it's ~42.5%
3. At `t=30s`, the fee reaches 5% and the MEV module disables itself
4. After that, only the normal LP Rewards (1%) applies

**Safety features:**
- `SameSecondAsDeployment` error prevents swaps in the same second as pool creation
- Maximum MEV module delay: 120 seconds (enforced by hook)
- `delayGuard` of 1 second prevents boundary condition issues in fee calculation

## Security

### Audit Fixes (v2)

The v2 deployment includes fixes for all issues identified in the security audit:

| # | Severity | Issue | Fix |
|---|----------|-------|-----|
| 1 | Critical | Shared `protocolFee` state across reentrant calls | Replaced storage variable with EVM transient storage (`tstore`/`tload`) |
| 3 | High | Zero slippage on fee conversion swaps | Added `maxSlippageBps` (default 5%) with `amountOutMinimum` enforcement |
| 4 | Medium | `getFee()` off-by-one at decay boundary | Changed `>` to `>=` with `+ delayGuard` |
| 7 | Medium | Raw `transfer`/`transferFrom` in vault | Replaced with OpenZeppelin `SafeERC20` |
| 9 | Low | Unused factory constructor parameters | Removed 4 unused params, simplified to `owner_` only |
| 10 | Low | Missing deprecated check in `deployTokenZeroSupply` | Added `if (deprecated) revert Deprecated()` |
| 13 | Low | Missing event on `setVaultExtension` | Added `SetVaultExtension` event |

### Transient Storage

The protocol fee fix uses EVM Cancun transient storage (`tstore`/`tload`) to isolate the protocol fee value per swap context. Transient storage is automatically cleared at the end of each transaction, and each write to `PROTOCOL_FEE_SLOT` correctly sets the fee for the subsequent `_afterSwap` read - even during reentrant fee collection swaps.

This requires the `cancun` EVM version, which Base supports since the Dencun upgrade.

## Wayfinder Integration

Cross-chain DeFi capabilities via [Wayfinder Paths](https://github.com/WayfinderFoundation/wayfinder-paths-sdk). Two tiers:

- **Tier 1 (REST)**: Swap quotes, token resolution, multi-chain balances, pool data. Always available.
- **Tier 2 (CLI bridge)**: Execute swaps, run strategies, Hyperliquid trading. Requires Python 3.12+ and `wayfinder-paths`.

### WayfinderClient

```typescript
import { WayfinderClient } from '@clawnch/clawncher-sdk';

const wf = new WayfinderClient({
  apiKey: 'wk_...',          // Wayfinder API key (X-API-KEY header)
  apiUrl: 'https://...',     // Optional: override API URL
  pythonPath: '/usr/bin/python3', // Optional: custom Python path
});
```

### Wayfinder REST API

These methods call `strategies.wayfinder.ai/api/v1` directly. No Python required.

#### quoteSwap(params)

```typescript
const quote = await wf.quoteSwap({
  fromToken: '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48', // USDC Ethereum
  toToken: '0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913',   // USDC Base
  fromChain: 1, toChain: 8453,
  fromWallet: '0x...', amount: '5000000', slippage: 0.005,
});
```

Supported chains: Ethereum (1), Base (8453), Arbitrum (42161), Polygon (137), BSC (56), Avalanche (43114), HyperEVM (999).

#### resolveToken / searchTokens / getBalances

```typescript
const token = await wf.resolveToken('USDC', 8453);
const results = await wf.searchTokens('pepe', 'base');
const balances = await wf.getBalances('0x...');
```

Other REST methods: `getGasToken()`, `getWalletActivity()`, `getPools()`, `getHyperliquidFunding()`, `getHyperliquidCandles()`, `getHyperLendMarkets()`.

### Wayfinder CLI Bridge

Requires Python 3.12+ and `pip3 install wayfinder-paths`. Signs transactions locally.

```typescript
const status = await wf.checkPython();
if (status.wayfinderInstalled) {
  await wf.executeSwap({ kind: 'swap', walletLabel: 'main', amount: '5', fromToken: 'usd-coin', toToken: 'ethereum' });
  await wf.runStrategy({ strategy: 'basis_trading_strategy', action: 'status' });
}
```

### Wayfinder MCP Tools

| Tool | Description | Python Required |
|------|-------------|:-:|
| `wayfinder_swap` | Cross-chain swap quotes and execution | Execute only |
| `wayfinder_balances` | Multi-chain wallet balances with activity | No |
| `wayfinder_tokens` | Resolve/search tokens across chains | No |
| `wayfinder_strategy` | List and run DeFi strategies | Yes |

Environment variables: `WAYFINDER_API_KEY` (required), `WAYFINDER_API_URL` (optional), `WAYFINDER_PYTHON_PATH` (optional).

### Wayfinder Python Adapter

For Wayfinder strategies that want to deploy tokens via Clawnch:

```python
from clawnch_adapter import ClawnchAdapter
adapter = ClawnchAdapter(api_key="your-clawnch-api-key")
result = await adapter.deploy_token(name="Strategy Token", symbol="STRAT")
fees = await adapter.get_fees("0x...")
```

## v0.1.0 Migration Notes

### Breaking Changes

- **`vestedDevBuy` removed from `DeployOptions`**: Use `vault` with a lockup for token lockup. `claimVestedDevBuy()` now throws `ClawnchDeployError`.
- **`vanity` is now a boolean**: Pass `true`/`false` instead of a config object. The SDK handles mining internally with the `0xccc` prefix.
- **`deploy()` command syntax changed**: CLI now uses `--name` and `--symbol` flags instead of positional arguments.
- **`verifyToken()` removed**: Contract verification is handled automatically by the deployment infrastructure.
- **Pool config options removed**: `startingTick`, `tickSpacing`, `lpFee`, and `mevConfig` are no longer configurable — these are set by the approved infrastructure.
- **`airdrop` optional in `DeployOptions`**: Airdrop configuration uses `AirdropConfig { percentage, admin, merkleRoot, lockupDuration, vestingDuration }`.

### New Features

- **`dryRun` option**: Validate deployment config without submitting a transaction. Returns `DryRunResult` with `translatedConfig`, `valid`, `estimatedGas`, and `estimatedCostEth`.
- **`ClawnchPortfolio`**: Discover and track all Clawncher tokens for a wallet.
- **`ClawnchWatcher`**: Real-time event streaming for new token deployments.
- **`claimBatch()`**: Claim fees across multiple tokens in one call.
- **Structured errors**: All SDK errors now use `ClawnchDeployError` with typed `ClawnchErrorCode`.

### Upgrade Path

```typescript
// v2
const result = await deployer.deploy({
  name: 'My Token',
  symbol: 'MYTKN',
  tokenAdmin: account.address,
  rewards: { recipients: [...] },
  vanity: { enabled: true, prefix: 'ccc', maxAttempts: 10_000_000 },
  startingTick: -196618,
  tickSpacing: 200,
  lpFee: 10000,
  mevConfig: { startingFee: 800000, endingFee: 50000, decaySeconds: 30 },
});

// v0.1.0
const result = await deployer.deploy({
  name: 'My Token',
  symbol: 'MYTKN',
  tokenAdmin: account.address,
  rewards: { recipients: [...] },
  vanity: true,
});
```
