```typescript theme={null}
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);
