Build Your Own AA Wallet

This project is for anyone interested in developing their own smart contract wallet using the ERC-4337 standard. It's designed to help both developers and users in building and managing their AA wallets.

Features:

• Create smart contract wallets on any EVM compatible blockchain.
• Develop Multi-Signature AA wallets.
• Customize your AA wallet according to your needs.
• Send and receive tokens with your AA wallets.
• Manage wallet information in a database.
• Monitor wallet activities.

The project is rooted in account abstraction principles. It allows the creation and management of AA wallets on the BNB Smart Chain Testnet Network.

Modify the foundry.toml to deploy on different EVM compatible blockchains.

Made with watching a lot of tutorials, annoying a lot of mentors, and having a lot of self-loathing.

A Note on Design:

Frontend design isn't my forte, expect the charm of a 90s website, but with half the aesthetics. Bear with me if it's not to your taste.

Tech Stack:

• Next.js (Frontend)
• Foundry (Smart Contracts)
• Prisma (Backend)
• Rainbowkit
• Tailwind
• Userop
• Wagmi

Prerequisites

• Foundry
• WalletConnect account
• Supabase account
• Bscscan account
• Stackup account
• An existing Web3 wallet (etc. Metamask)

Getting Started

To get it started, first: Type npm install in the terminal. Then download the necessary packages in the /contracts folder with forge.

You need to create a .env file and fill in:

• BSC_RPC_URL
• PRIVATE_KEY
• BSCSCAN_API_KEY
• NEXT_PUBLIC_WALLET_CONNECT_PROJECT_ID

...So that you can deploy the contracts. After that, add these in the .env file:

• DATABASE_URL
• NEXT_PUBLIC_STACKUP_API_KEY
• YOUR_CONTRACT_ADDRESS

Then, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev

Open http://localhost:3000 with your browser to see the result.
