Function createLaunch

Creates a project launch via the Metaplex API.

Returns deserialized Umi transactions that can be signed and sent using standard Umi methods before calling registerLaunch.

Example

Bonding curve launch

const result = await createLaunch(umi, {}, {
  wallet: umi.identity.publicKey,
  launchType: 'bondingCurve',
  token: { name: 'My Token', symbol: 'MTK', image: 'https://gateway.irys.xyz/...' },
  launch: {},
});

Example

Bonding curve launch with a direct creator fee wallet

const result = await createLaunch(umi, {}, {
  wallet: umi.identity.publicKey,
  launchType: 'bondingCurve',
  token: { name: 'My Token', symbol: 'MTK', image: 'https://gateway.irys.xyz/...' },
  launch: { creatorFeeWallet: 'CreatorWalletAddress...' },
});

Example

Bonding curve launch with agent-derived creator fees

const result = await createLaunch(umi, {}, {
  wallet: umi.identity.publicKey,
  launchType: 'bondingCurve',
  token: { name: 'Agent Token', symbol: 'AGT', image: 'https://gateway.irys.xyz/...' },
  launch: { creatorFeeAgentMint: agentAssetAddress },
});

Example

Launchpool launch

const result = await createLaunch(umi, {}, {
  wallet: umi.identity.publicKey,
  launchType: 'launchpool',
  token: { name: 'My Token', symbol: 'MTK', image: 'https://gateway.irys.xyz/...' },
  launch: {
    launchpool: {
      tokenAllocation: 500_000_000,
      depositStartTime: new Date('2026-03-01T00:00:00Z'),
      raiseGoal: 250,
      raydiumLiquidityBps: 5000,
      fundsRecipient: 'RecipientWallet...',
    },
  },
});

// Sign and send using Umi directly
for (const tx of result.transactions) {
  const signed = await umi.identity.signTransaction(tx);
  await umi.rpc.sendTransaction(signed);
}
