ExponentVault.ixInitializeVault

Creates a new Strategy Vault. This is a static method since the vault doesn’t exist yet at call time. It sets up the vault PDA, mints the initial LP tokens, creates the Squads smart account for policy-gated execution, and registers the vault’s token entries.

​
Usage

import { ExponentVault } from "@exponent-labs/exponent-sdk";
import { PublicKey, Transaction, sendAndConfirmTransaction } from "@solana/web3.js";

const ix = ExponentVault.ixInitializeVault({
  payer: wallet.publicKey,
  mint: new PublicKey("So11111111111111111111111111111111111111112"), // Underlying mint
  manager: wallet.publicKey,
  seedId: new Uint8Array([1, 2, 3, 4, 5, 6, 7, 8]), // 8-byte unique seed
  feeTreasury: feeTreasuryAddress,
  feeTreasuryLpBps: 200, // 2% management fee
  tokenEntries: [
    {
      mint: usdcMint,
      priceId: { simple: { id: 0 } },
      tokenSquadsAccount: usdcSquadsAccount,
    },
  ],
  maxLpSupply: 1_000_000_000_000n,
  initialLpAmount: 1_000_000n,
  lpDecimals: 6,
  vaultType: { generic: {} },
  roles: {
    manager: [wallet.publicKey],
    curator: [],
    allocator: [],
    sentinel: [],
  },
  addressLookupTable: lookupTableAddress,
  squadsProgram: squadsV4ProgramId,
  squadsProgramConfig: squadsProgramConfigAddress,
  squadsTreasury: squadsTreasuryAddress,
  squadsSettings: squadsSettingsAddress,
  squadsVault: squadsVaultAddress,
}, env);

const tx = new Transaction().add(ix);
await sendAndConfirmTransaction(connection, tx, [wallet]);

Deriving the Vault Address

After initialization, you can derive the vault PDA from its seed: 
const [vaultAddress] = ExponentVault.deriveVaultAddress(seedId);
