Deploy an Earn Vault and Get Revenue Share

Any builder can deploy a private or public Earn Vault and get revenue share in just a few lines of code.

const tokenMint = 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v'; // USDC
const kaminoManager = new KaminoManager(rpc, slotDuration);

// Configure vault
const kaminoVaultConfig = new KaminoVaultConfig({
  admin: adminSigner,
  tokenMint: tokenMint,
  performanceFeeRatePercentage: new Decimal(10.0),
  managementFeeRatePercentage: new Decimal(1.0),
  name: 'Earn USDC Vault',
  vaultTokenSymbol: 'kUSDC',
  vaultTokenName: 'kUSDC receipt',
});

const { vault: vaultSigner, initVaultIxs: instructions } =
  await kaminoManager.createVaultIxs(kaminoVaultConfig);
