Error: Invalid Address in Metamask
As a developer working with smart contracts, it’s not uncommon to encounter errors when trying to deploy your code on the Ethereum blockchain using the MetaMask wallet. One common issue that can arise is the “Invalid address” error.
In this article, we’ll explore how to resolve this error and get your smart contract deployed successfully using Metamask.
What is an invalid address?
An invalid address in Ethereum refers to a string of 40 characters (or less) that represents their Ethereum account. When you try to send or receive Ether (ETH) using the MetaMask wallet, it will reject the transaction if the sender’s wallet has a different address than what the recipient specifies.
Symptoms of an Invalid Address Error
The error “Invalid address” can manifest in several ways:
- Transaction fails: You receive an error message indicating that the transaction failed due to an invalid address.
- Error codes

0x7cis often used to indicate an invalid address.
How to fix the Error: Invalid Address
To resolve the “Invalid address” error in Metamask, follow these steps:
1. Check your MetaMask settings
Make sure you are using the correct wallet mnemonic and private key for your contract’s account. You can do this by going to MetaMask > Wallets > My Wallets > View details.
Make sure that the account name, address, and mnemonic match what is listed in your contract documentation and on-chain.
2. Verify your contract deployment
Double-check that you’ve deployed your contract correctly using a tool like Truffle Suite or Remix. Make sure to include the correct txHash and blockNumber when sending Ether using Metamask.
If you’re still experiencing issues, try:
- Hardcoding the address: In some cases, it is possible that the address is hardcoded in your contract or script. Check if this is the case by reviewing your code.
- Using a different wallet: Try deploying with a different MetaMask wallet to see if the issue persists.
3. Update your metamask settings
If none of the above steps resolve the issue, try updating your Metamask settings:
- Go to Settings > Wallets & Accounts
- Find and select the correct address
- Save changes
Conclusion
Resolving the “Invalid address” error in Metamask is relatively straightforward. By checking your MetaMask settings, verifying your contract deployment, and updating your wallet settings, you should be able to resolve this issue and deploy your smart contract successfully.
