RPC Provider

Loop Decoder requires an RPC provider to fetch transaction data. To configure RPC providers, implement a getPublicClient function that returns a PublicClientObject based on the chain ID.

import { createPublicClient, http } from 'viem'

// Create a public client for the Ethereum Mainnet network
const getPublicClient = (chainId: number) => {
  return {
    client: createPublicClient({
      transport: http('https://rpc.ankr.com/eth'),
    }),
  }
}

PublicClientObject Structure

The PublicClientObject consists of two properties:

client

An instance of Viem’s PublicClient
See the Viem documentation for more details

config

An optional configuration object with the following properties:

traceAPI: Specifies the tracing API to use (default: parity)
- parity - for Parity/OpenEthereum RPC nodes
- geth - for Geth RPC nodes
- none - when tracing is not supported
