import { PublicKey } from "@solana/web3.js";

const SQUADS_PROGRAM_ID = new PublicKey("SQDS4ep65T869zMMBKyuUq6aD6EgTu8psMjkvj52pCf");

// Seeds: ["multisig", createKey]
const [multisigPda, bump] = PublicKey.findProgramAddressSync(
  [Buffer.from("multisig"), createKey.toBuffer()],

## Verification

Verify the deployed program matches the audited source code:

```bash
# Install solana-verify tool
cargo install solana-verify

# Verify V4 Multisig on mainnet
solana-verify get-program-hash \
  -u https://api.mainnet-beta.solana.com \
  SQDS4ep65T869zMMBKyuUq6aD6EgTu8psMjkvj52pCf

# Verify Smart Account on mainnet
solana-verify get-program-hash \
  -u https://api.mainnet-beta.solana.com \
  SMRTzfY6DfH5ik3TKiyLFfXexV8uSG3d2UksSCYdunG
```

The hash should match the official audited build hash published by Squads.
