Function neonTreeAccountAddressSync

  • neonTreeAccountAddressSync(
        neonWallet: string,
        neonEvmProgram: PublicKey,
        chainId: number,
        nonce: number,
    ): [PublicKey, number]

  • Derives a synchronous Neon tree account address for the given Neon wallet, EVM program, chain ID, and nonce.

    This function computes a program-derived address (PDA) for a tree account within the Neon EVM. The address derivation is based on multiple seed components:

    • Seed version: Ensures compatibility with account derivation logic.
    • Tag ("TREE"): Identifies this PDA as a tree account.
    • Neon wallet address: The Ethereum-style address corresponding to the Solana wallet.
    • Chain ID: Differentiates accounts across different Neon chains.
    • Nonce: The last scheduled nonce for Solana user

    Parameters

    • neonWallet: string

      The Ethereum-style Neon wallet address in hexadecimal format.

    • neonEvmProgram: PublicKey

      The public key of the Neon EVM program.

    • chainId: number

      The chain ID associated with the Neon network.

    • nonce: number

      A unique identifier is required to validate the address of the TreeAccount.

    Returns [PublicKey, number]

    A tuple containing:

    • PublicKey: The derived tree account address.
    • number: The bump seed used in PDA derivation.

    Example

    const [treeAccount, bump] = neonTreeAccountAddressSync(
      "0x1234567890abcdef1234567890abcdef12345678",
      neonEvmProgram,
      245022926,
      1
    );
    console.log("Neon Tree Account Address:", treeAccount.toBase58());
