        transaction: EmulateTransactionData,
        maxStepsToExecute?: number,
        provideAccountInfo?: any,
    ): Promise<any>

  • Emulates the execution of a given Ethereum-like transaction on Neon EVM.

    This function is used to simulate the execution of a transaction without broadcasting it.

    Parameters

    • transaction: EmulateTransactionData

      The transaction data to emulate.

    • OptionalmaxStepsToExecute: number = 500000

      The maximum number of execution steps.

    • OptionalprovideAccountInfo: any = null

      Optional account information to include.

    Returns Promise<any>

    A promise resolving to the emulation result.

getBalance

  • getBalance(
        address: string,
        chainId: number,
    ): Promise<NeonApiResponse<NeonBalance>>

  • Retrieves the balance of a given Neon EVM account.

    Parameters

    • address: string

      The Neon wallet address.

    • chainId: number

      The Chain ID of the Neon network.

    Returns Promise<NeonApiResponse<NeonBalance>>

    A promise resolving to the account balance.

    Example

    const balance = await neonClient.getBalance("0xNeonAddress", 245022926);
    console.log(balance);

getHolder

  • getHolder(publicKey: PublicKey): Promise<NeonApiResponse<HolderAccount>>

  • Fetches holder account information based on the given Solana public key.

    Parameters

    • publicKey: PublicKey

      The Solana public key of the holder account.

    Returns Promise<NeonApiResponse<HolderAccount>>

    A promise resolving to the holder account details.

    Example

    const holder = await neonClient.getHolder(new PublicKey("SolanaPublicKey"));
    console.log(holder);

getStorageAt

  • getStorageAt(contract: string, index: number): Promise<any>

  • Retrieves the storage value at a given index for a specified Neon contract.

    Parameters

    • contract: string

      The Neon contract address.

    • index: number

      The storage index to query.

    Returns Promise<any>

    A promise resolving to the storage value.
