XdcRpc Class

The XdcRpc class provides a set of methods to interact with the XDC blockchain using RPC calls.

Installation

To use the XdcRpc class, you need to have the required dependencies installed. Run the following command:

npm install @web5nexus/web3auth-core

Usage

Importing the XdcRpc Class

To use the XdcRpc class, import it from your code:

import XdcRpc from '@web5nexus/web3auth-core';

Initializing the XdcRpc Class

To create an instance of the XdcRpc class, you need to provide a SafeEventEmitterProvider as a parameter.

const provider = ...; // Initialize your provider
const xdcRpc = new XdcRpc(provider);

Methods

getChainId(): Promise<string>

This method retrieves the Chain ID of the connected XDC chain.

Example usage:

const chainId = await xdcRpc.getChainId();
console.log('Chain ID:', chainId);

getAccounts(): Promise<any>

This method retrieves the user's XDC account address.

Example usage:

const address = await xdcRpc.getAccounts();
console.log('Account address:', address);

getBalance(): Promise<string>

This method retrieves the balance of the user's XDC account.

Example usage:

const balance = await xdcRpc.getBalance();
console.log('Account balance:', balance);

sendTransaction(amountInWei: string, toAddress: string, maxPriorityFeePerGas?: string, maxFeePerGas?: string): Promise<any>

This method sends a transaction on the XDC blockchain.

• amountInWei (string): The amount to send in Wei.
• toAddress (string): The recipient's address.
• maxPriorityFeePerGas (optional, string): The maximum priority fee per gas.
• maxFeePerGas (optional, string): The maximum fee per gas.

Example usage:

const amountInWei = '1000000000000000000'; // 1 XDC
const toAddress = '0x...'; // Recipient's address
const receipt = await xdcRpc.sendTransaction(amountInWei, toAddress);
console.log('Transaction receipt:', receipt);

signMessage(): Promise<any>

This method signs a message using the user's XDC account.

Example usage:

const signedMessage = await xdcRpc.signMessage();
console.log('Signed message:', signedMessage);

getPrivateKey(): Promise<any>

This method retrieves the private key associated with the user's XDC account.

Example usage:

const privateKey = await xdcRpc.getPrivateKey();
console.log('Private key:', privateKey);

Conclusion

The XdcRpc class from the @web5nexus/web3auth-core library provides a convenient way to interact with the XDC blockchain using RPC calls. With its methods, you can retrieve the chain ID, account address, balance, send transactions, sign messages, and get the private key.
