Get PDA and Bump

Calculates a Program Derived Address (PDA) and its bump seed from a program address and seeds. Automatically handles encoding of different seed types (strings, addresses, and bigints).

Returns: Promise<{pda: Address, bump: number}>


const { pda, bump } = await connection.getPDAAndBump(
  programAddress,
  ["my-seed", walletAddress, 123n]
);

Parameters

programAddress: Address - The program address to derive the PDA from
seeds: Array<String | Address | BigInt | Uint8Array> - Array of seeds to derive the PDA. Can be a mix of:
- string - Will be encoded as UTF-8 bytes
- Address - Will be encoded as a Solana address
- BigInt - Will be encoded as 8-byte little-endian bytes
- Uint8Array - Will be used as-is (for custom encoding strategies)

Examples

Create a PDA with string seeds:


const { pda, bump } = await connection.getPDAAndBump(
  programAddress,
  ["my-seed", "another-seed"]
);

Create a PDA with mixed seed types:


const { pda, bump } = await connection.getPDAAndBump(
  programAddress,
  ["my-seed", walletAddress, 123n]
);

Create a PDA with just a number seed:


const { pda, bump } = await connection.getPDAAndBump(
  programAddress,
  [123n]
);
