Solution for Raw Reject (Error): Invalid Address Error in Web3.js

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

What is an Invalid Address Error?

A invalid address error occurs when a JavaScript object cannot be converted to a Web3.js wallet address. This can happen for a variety of reasons, such as:

  • The input data does not match the expected format
  • The network is down or experiencing significant latency
  • The wallet is running out of gas

Causes of Raw Reject (Error): Invalid Address Error

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

  • Invalid input: Make sure that the input passed to Web3.fromRawTransaction or Web3.eth.sendSignedMessage is in the expected format.
  • Network issues: Low network latency or congestion can cause errors.
  • Wallet out of fuel: If your wallet is low on funds, sending transactions may fail.

Solution 1: Increase Web3.js options

One common solution is to increase the MaxPriorityFee option in Web3.providers.HttpProvider. This will allow Web3.js to prioritize the transaction more and reduce the chance of errors due to 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 chance of errors due to network issues.

const wallet = new MetaMaskWallet();
wallet.connect(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 overloaded. Please wait a while and try again.
}

Solution 4: Check the Wallet Fund

Before attempting to send transactions, make sure that there are enough funds in the wallet.

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

Best Practices

To reduce the occurrence of raw reject (error): Invalid address errors:

  • Use maxPriorityFee to give transactions a higher priority
  • Choose an efficient wallet that is optimized for low memory environments
  • Check the network status before attempting to send transactions
  • Ensure sufficient funds in the wallet

By following these solutions and best practices, you should be able to reduce the number of raw reject (error): Invalid address errors when using Web3.js.

Here is an example code snippet that shows how to use maxPriorityFee:

“` javascript

const provider = new Web3.providers.HttpProvider(‘

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

// Connect to the wallet and perform the transaction

const wallet = new MetaMaskWallet();

wallet.connect(provider);

const tx = {

from: ‘0x…’,

to: ‘0x…’,

value: ‘10000000000000000000’, // Set the gas limit

data: ‘0x…’,

nonce: “…”.
