Metamask: How to resolve unhandled rejection (error): invalid address error with web3 js

Resolving Unhandled Reject (Error): Invalid Address Error with Web3.js

Unhandled Reject (Error): Invalid Address Error is a common issue that can occur when using the Web3.js library, especially in environments with low memory. In this article, we will explore how to resolve Unhandled Reject (Error): Invalid Address errors and provide some best practices to ensure optimal performance.

What is an invalid address?

The invalid address error occurs when a JavaScript object cannot be converted to a Web3.js wallet address. This can happen for a number of reasons, including:

• The input data does not match the expected format

• The network is down or has high latency

• Your wallet is running out of gas

Causes of Unhandled Reject (Error): Invalid Address

Before diving into the solutions, it is important to understand the causes of this error. Here are some common causes:

• Invalid input: Make sure the input data passed to Web3.fromRawTransaction or Web3.eth.sendSignedMessage matches the expected format.

• Network issues

  

  : Low network latency or congestion can cause errors.

• Wallet running out of gas: If your wallet is running low on funds, it may not be able to send transactions.

Solution 1: Add Web3.js settings

One common solution is to add the MaxPriorityFee option to Web3.providers.HttpProvider. This allows Web3.js to give the transaction more priority, reducing the chance of errors caused by low network latency or congested networks.

const provider = new Web3.providers.HttpProvider('
provider.maxPriorityFee = 2; // Increase the maximum priority fee

Solution 2: Use a more efficient wallet

Another solution is to use a more efficient wallet, such as MetaMask or Trust Wallet. These wallets are optimized for low-memory environments and can reduce the likelihood of errors caused by network issues.

const wallet = new MetaMaskWallet();
wallet.connection(provider);

Solution 3: Check the network status

Before attempting to send transactions, check the network status using “Web3.eth.netStatus()”.

const networkStatus = await Web3.eth.netStatus();
if (!networkStatus.status) {
// The network is down or congested. Please wait a moment and try again.
}

Solution 4: Check Wallet Fund

Make sure there are enough funds in your wallet before attempting to send transactions.

const balance = await Web3.eth.getBalance(wallet.address);
if (balance < 1000) { // Set a low threshold for funds
// Your wallet is running low on gas. Please wait a moment and try again.
}

Best Practices

To minimize the occurrence of Unhandled Rejection (Error): Invalid Address Errors:

• Use maxPriorityFee' to give more priority to transactions

• Choose a powerful wallet that is optimized for low-memory environments

• Check network status before attempting to send transactions

• Make sure you have sufficient funds in your wallet

By following these solutions and best practices, you should be able to reduce the occurrence of Unhandled Rejection (Error): Invalid Address errors when using Web3.js.

Example Code

Here is a sample code snippet that demonstrates how to use maxPriorityFee:

“ javascript

const provider = new Web3.providers.HttpProvider(‘

provider.maxPriorityFee = 2; // Increase the maximum priority fee

// Connect to wallet and create transaction

const wallet = new MetaMaskWallet();

wallet.connection(provider);

const tx = {

from: ‘0x…’,

container: “0x…”,

value: ‘100000000000000000000’, // Set gas limit

data: ‘0x…’,

nonce: ‘…’.
