ForkError

Represents an error thrown when attempting to fetch a resource from a Forked transport. If the underlying JSON-RPC call has an error code, the error code will be proxied to the ForkError. Most tevm methods return these errors as values if throwOnFail is set to false and a forkUrl is provided

Example

try { // Some operation that can throw an ForkError } catch (error) { if (error instanceof ForkError) { console.error(error.message); // Handle the account locked error } }

To debug this error check to see if there might be a misconfiguration or rate limit of the fork transport.

If the issue is a rate limit consider using the rateLimit transport options to limit how many requests tevm are made.

import { rateLimit, http } from "@tevm/jsonrpc"
import { createMemoryClient } from "@tevm/memory-client"

const client = createMemoryClient({
  fork: {
    transport: rateLimit(
      http('https://mainnet.optimism.io'), { browser: false, requestsPerSecond: 25 }
    )
  )
}}
