As a developer who works with intelligent contracts, it is not uncommon to respond to errors when trying to distribute the Ethereum blockchain code using the Metamask portfolio. A common problem that can occur is the “not valid address” error.

In this article, we will study how to terminate this error and successfully distribute your smart contract using Metamask.

What is a valid address?

NO -Valid Address in Ethereum refers to a string of 40 characters (or not), which is an Ethereum account. When trying to send or receive Ether (ETH) using the Metamask portfolio, it will refuse the transaction if the sender’s portfolio has a different address than what the correct recipient.

Symptoms of error in Valido

The “non -valid address” error can occur in different ways:
