Overview

LaunchFactory is the single entry point for every Makx launch. It deploys tokens, bonding curves (as EIP-1167 clones), and prepools. It also manages symbol uniqueness and prepool symbol reservations.

Write Functions

function createLaunch(
    string calldata name,
    string calldata symbol,
    bytes32 salt,
    TokenENS.TokenMetadata calldata meta,
    uint256 minDevBuyTokens
) external payable returns (address tokenAddr, address curveAddr)
Deploys a standard launch (token + bonding curve clone + ENS subdomain). Send msg.value > 0 for an atomic dev buy. salt is combined with msg.sender for deterministic, front-run-resistant clone addresses.
function createPrepool(
    bytes32 salt,
    string calldata name,
    string calldata symbol,
    TokenENS.TokenMetadata calldata meta,
    uint256 minBalance,
    uint256 deployTime,
    uint256 minContribution
) external payable returns (address prepoolAddr)
Deploys a Prepool contract. deployTime is an expiry deadline — the prepool must deploy before this time or it can be cancelled. Max 7 days; defaults to 7 days if 0; reverts InvalidDeployTime if greater than 7 days. The symbol is soft-reserved until the deadline. The salt must produce an address whose lower 14 bits satisfy V4 hook flags (bit 6: AFTER_SWAP, bit 2: AFTER_SWAP_RETURNS_DELTA). Use predictPrepoolAddress(salt) to validate off-chain.
function createPrepoolLaunch(
    string calldata name,
    string calldata symbol,
    bytes32 curveSalt,
    TokenENS.TokenMetadata calldata meta
) external payable returns (address tokenAddr, address curveAddr, uint256 tokensOut)
Called only by a registered Prepool. Deploys token + bonding curve. prepoolAllocationBps of supply goes directly to the prepool; the rest to the curve.
function setParams(
    uint256 _totalSupply,
    uint16 _platformFeeBps,       // max 1000 (10%)
    uint256 _virtualEth,
    uint256 _virtualTokens,
    uint256 _salePercentBps,      // 1–10000
    uint16 _prepoolAllocationBps  // salePercentBps + prepoolAllocationBps ≤ 10000
) external onlyOwner
Updates launch parameters. Only affects future launches.
function setTokenENS(TokenENS _tokenENS) external onlyOwner
Sets the TokenENS registrar address.
function releaseSymbol(string calldata symbol) external
Called by a prepool on cancellation to release its soft symbol reservation.

View Functions

function predictCurveAddress(bytes32 salt) external view returns (address)
function predictPrepoolAddress(bytes32 salt) external view returns (address)
Both include msg.sender in the salt derivation, so the predicted address is caller-specific.
