DEVELOPERS / LAUNCH

Launching a token

ABIs live in contracts/abi/, one JSON per contract. Addresses come from config.js, where anything not deployed is null, so every snippet below starts by refusing to run without one.

Model V2

ethers v6 · AgiV2LaunchFactory

const FACTORY = window.AGI_CONFIG.contracts.launchpad.v2.factory; // null if not deployed
if (!FACTORY) throw new Error('AGI Launchpad V2 is not open yet');

const factory = new ethers.Contract(FACTORY, FACTORY_ABI, signer);

// 1. Pick a config and a quote asset. address(0) = native ETH.
const configId  = 0n;
const pairToken = ethers.ZeroAddress;

const cfg = await factory.getLaunchConfig(configId);   // supply, curveFeeBps, phantomQuote,
                                                       // graduationThreshold, poolFee,
                                                       // tickSpacing, enabled
if (!cfg.enabled) throw new Error('launch config disabled');

// 2. Pin the terms you were quoted. Zero waives the check.
const economics = await factory.previewLaunchEconomics(configId, pairToken);

const params = {
  name: 'My Token',
  symbol: 'MYT',
  logo: 'https://.../logo.webp',
  description: 'What it is.',
  socials: { twitter: '', telegram: '', discord: '', website: '', farcaster: '' },
  creatorFeeRecipient: await signer.getAddress(),
  creatorTaxBps: 100,                    // 1%; ceiling is factory.maxCreatorTaxBps()
  buybackEnabled: false,                 // always false on the AGI Launchpad
  expectedEconomics: economics,
  salt: ethers.hexlify(ethers.randomBytes(32)),
};

// 3. Optional: know the addresses before you send.
const deployer = await factory.launchDeployer();
// AgiV2LaunchDeployer.predictLaunchAddresses(deployment) -> (token, curve)

// 4. Send. msg.value must equal launchFee() exactly.
const fee = await factory.launchFee();
const tx = await factory['launchToken((string,string,string,string,(string,string,string,string,string),address,uint16,bool,bytes32,bytes32),uint256,address,address[])'](
  params, configId, pairToken, [],       // up to 32 snipe-tax exemptions
  { value: fee }
);
const receipt = await tx.wait();          // TokenLaunched(token, curve, deployer, ...)

The three-argument overload without the exemption list behaves identically; the launching account and its fee recipient are exempted either way. Common reverts: LaunchFeeNotPaid (value must equal the fee, not merely cover it), NotWhitelisted (launching is closed to the public), CreatorTaxTooHigh, LaunchEconomicsMismatch (the terms moved after your preview) and PairTokenNotApproved.

Model V1

const factory = new ethers.Contract(FACTORY, FACTORY_V1_ABI, signer);
const fee     = await factory.launchFee();
const openingBuy = ethers.parseEther('0.05');   // anything above the fee is spent buying

const params = {
  name: 'My Token',
  symbol: 'MYT',
  logo: 'https://.../logo.webp',
  description: 'What it is.',
  socials: { twitter: '', telegram: '', discord: '', website: '', farcaster: '' },
  feeWallet: await signer.getAddress(),   // receives LP fees and the opening buy
};

const tx = await factory.launchToken(
  params,
  0n,                                     // launchConfigId

  ethers.hexlify(ethers.randomBytes(32)), // salt
  { value: fee + openingBuy }
);
