transferWithSeed static method

TransactionInstruction transferWithSeed({ required Pubkey fromPubkey, required Pubkey basePubkey, required Pubkey toPubkey, required BigInt lamports, required String seed, required Pubkey programId, })

Generates a transaction instruction that transfers lamports from one account to another.

Keys:

• fromPubkey The account that will transfer lamports.
• basePubkey The base public key used to derive the funding account address.
• toPubkey The account that will receive the transferred lamports.

Data:

• lamports The amount of lamports to transfer.
• seed The seed used to derive the funding account address.
• programId The program id used to derive the funding account address.

Implementation

static TransactionInstruction transferWithSeed({
  required final Pubkey fromPubkey,
  required final Pubkey basePubkey,
  required final Pubkey toPubkey,
  required final BigInt lamports,
  required final String seed,
  required final Pubkey programId,
}) {
  final List<AccountMeta> keys = [
    AccountMeta.writable(fromPubkey),
    AccountMeta.signer(basePubkey),
    AccountMeta.writable(toPubkey),
  ];

  final List<Iterable<int>> data = [
    borsh.u64.encode(lamports),
    borsh.rustString().encode(seed),
    borsh.pubkey.encode(programId.toBase58()),
  ];

  return _instance.createTransactionIntruction(
    SystemInstruction.transferWithSeed,
    keys: keys,
    data: data,
  );
