Smart Contract Interaction

By Wallett Engineers · · Sep 5, 2025

What You'll Learn

This guide will show you how to interact with Ethereum smart contracts using Wallett. You'll understand how to deploy and invoke contract functions for token transfers, reading data, and handling events.

1

Connect to Ethereum Smart Contracts


const contractABI = [ /* ABI entries here */ ];
const contractAddress = "0xYourContractAddress";

const provider = new ethers.providers.Web3Provider(window.ethereum);
const wallet = provider.getSigner();
const contract = new ethers.Contract(contractAddress, contractABI, wallet);
2

Send Transactions

Example of sending a transaction to deposit funds:


const tx = await contract.deposit({
    value: ethers.utils.parseEther("0.5"),
    gasLimit: 200000
});
await tx.wait();
3

Read Contract Data

Query a contract for specific information in a read-only call:


const balance = await contract.getBalance(userAddress);
console.log("Balance:", ethers.utils.formatEther(balance));
4

Handle Events

Subscribe to smart contract events and filter for specific topics:


contract.on("Transfer", (from, to, amount) => {
    console.log(`Transfer: ${from} → ${to} - ${ethers.utils.formatEther(amount)} ETH`);
});
