Function createHolderAccountTransaction

  • createHolderAccountTransaction(
        neonEvmProgram: PublicKey,
        solanaWallet: PublicKey,
        holderAccount: PublicKey,
        holderSeed: string,
    ): Promise<Transaction>

  • Creates a Solana transaction to initialize a holder account.

    This function constructs a transaction containing:

    • An instruction to create an account with a deterministic seed.
    • An instruction to initialize the holder account within the Neon EVM program.

    The holder account is used for storing temporary transaction data and processing Neon EVM transactions.

    Parameters

    • neonEvmProgram: PublicKey

      The public key of the Neon EVM program.

    • solanaWallet: PublicKey

      The public key of the Solana wallet initiating the transaction.

    • holderAccount: PublicKey

      The public key of the holder account to be created.

    • holderSeed: string

      The unique seed used to derive the holder account address.

    Returns Promise<Transaction>

    A Solana Transaction object, ready to be signed and sent.

    Example

    const transaction = await createHolderAccountTransaction(
      neonEvmProgram,
      solanaWallet,
      holderAccount,
      "unique-holder-seed"
    );
    transaction.recentBlockhash = (await connection.getLatestBlockhash()).blockhash;
    const signature = await connection.sendTransaction(transaction, [signer]);
