Sending Custom Interactions with a Contract Using Metamask: A Step-by-Step Guide

With the growing demand for Decentralized Financial (DeFi) applications, many users are looking for ways to interact with smart contracts on platforms like MM.finance. However, one common challenge users face is that their websites or applications may not support custom interactions or require an external wallet to execute them. This is where Metamask comes in – a popular cryptocurrency wallet and browser extension that enables seamless interaction with DeFi protocols.

In this article, we will explore how to send custom interactions with contracts using Metamask, specifically for the MM.finance protocol. We will also address a common challenge users face when trying to approve the spending of a MM.finance token before it is published: how to do it without relying solely on the functionality of their website.

What is a custom interaction?

Custom interaction refers to interacting with smart contracts using external wallets or applications, rather than relying solely on the protocol’s built-in functionality. In the case of MM.finance, custom interactions allow users to send custom transactions, such as approving token consumption, before it is published without having to directly interact with the website.
