Ethereum: Troubleshooting “Error HH604: Troubleshooting ‘Missing Trie Node’ When Forking BSC Mainnet Using Hardhat”

As a developer working with Ethereum, you’re probably familiar with the thrill of building custom blockchain applications. However, even with experience, issues can arise when trying to fork and deploy new chains. In this article, we’ll dive into the specifics of a common error that occurs when trying to fork Binance Smart Chain (BSC) using Hardhat: “Error HH604: Troubleshooting ‘Missing Trie Node’.”

The Problem

When trying to fork BSC mainnet using Hardhat, you may encounter an error related to missing trie nodes. The hardhat command, which is part of the popular development environment for Ethereum development tools (Hardhat), attempts to establish a connection to a BSC mainnet node. However, if there are issues with the trie node connectivity or configuration, this error may occur.

Error HH604

Error HH604 indicates that there was an issue related to the lack of trie nodes, which is crucial to establishing a secure and functional blockchain network. The exact details of this error may vary depending on the version of Hardhat, the BSC mainnet, and the underlying Ethereum development tools used.

Troubleshooting Steps

To troubleshoot the “trie node missing” error using Hardhat, follow these steps:

• Check your network connection: Make sure your internet connection is stable and working properly.

• Check your node configuration: Double-check that you have correctly configured the BSC mainnet node using npx hardhat node --fork.

• Check for node issues: Look for errors or warnings related to node connectivity or trie node configuration in your Hardhat logs.

• Update Hardhat and dependencies: Make sure you are running the latest version of Hardhat and all required dependencies.

• Check trie node usage

  : Make sure the useTrie option is set to true when creating a new wallet or network object.

Example solution

Here is an example of how you can troubleshoot and resolve the “node trie missing” error using Hardhat:

const { HardhatRuntimeEnvironment } = require('hardhat');
async function main() {
const { networks, getChainId } = await ethers.getNetworks();
// Check network configuration
console.log(Available networks: ${networks});
// Check for node issues
if (getChainId() !== 'bsc-1') {
throw new Error('Missing trie node error detected');
}
// Update Hardhat and dependencies
await hardhatUpdate();
}
async function hardhatUpdate() {
const { ethers } = require('@nomicfoundation/hardhat-ethers');
// Update Ethers.js version
await ethers.updateEthersVersion('4.10.0', '1.21.14');
// Update Hardhat runtime version
await ethers.updateRuntimeVersion('mainnet', '1.9.3');
}
main().catch((error) => {
console.error(error);
});

By following these troubleshooting steps and example solution, you should be able to resolve the “trie node missing” error when trying to fork the BSC mainnet using Hardhat.
