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.
