Solidity Day 3: Creating a Shared Wallet with Allowances (Foundry Project)

Description

Day 3 — Building a Shared Wallet Smart Contract (Web3 Learning Series) In this video, I build a complete Shared Wallet smart contract using Solidity and Foundry, including allowance systems, owner permissions, and secure withdrawal logic. 🔹 What’s covered in this video: • How a shared wallet works on Ethereum • Writing an owner-controlled allowance system • Deposit & withdraw functions with proper checks • Using custom Solidity errors & events • Implementing allowance mapping • Writing a full Foundry deployment script (wallet.s.sol) • Deploying the contract on a local Anvil blockchain • Testing contract interactions step-by-step If you're learning Solidity, Foundry, or smart contract architecture, this project is a great hands-on exercise to understand access control, state updates, and wallet logic. 📺 This is the full version of the video. A shorter version is posted on LinkedIn due to upload limits.
