INTEGRATION

launch() is permissionless and payable. msg.value = the launch fee (read launchFeeWei()) plus any dev buy, which runs in the same transaction before a sniper can move. It deploys the token at an unpredictable CREATE2 address, opens the pool and locks 100% of supply as liquidity.

// classic (coin/WETH), any chain's launchpad factory
function launch(
  string name, string symbol, string metadataURI,
  uint256 devBuyMinTokensOut, address feeRecipient
) payable returns (address token, address pool, uint256 lpTokenId);

// flex (choose the quote token: WETH / USDG / a stock / any CA)
function launch(
  address pairToken, uint256 startingMcapPair,
  string name, string symbol, string metadataURI,
  uint256 devBuyMinTokensOut, uint256 devBuyPairIn, address feeRecipient
) payable returns (address token, address pool, uint256 lpTokenId);

feeRecipient = address(0) defaults to the caller. Pass the chain's rewards vault to launch in managed (CTO-able) rewards mode. Contracts are verified on each explorer — read them there.

Buy = swap the quote token (native ETH is wrapped for you) into the coin; sell = the reverse, unwrapping back to native. Use the venue's router above. v3 coins use exactInputSingle on the swap router; v4 coins route through the Uniswap UniversalRouter against the coin's pool key; UP coins use the Slipstream router keyed by tick spacing. Because these are ordinary pools, an off-the-shelf Uniswap SDK works too.
