Burner

When receiving hackathon prizes or one-time payments, we often face a common question: 'Which wallet should I use?' Using multiple addresses within the same "wallet" can become messy - we lose track of which address was used for what, which wallets are linked, and which addresses remain clean for activities we'd rather keep separate.

Burner solves this problem by leveraging ERC4337 to create user-friendly smart wallets that work seamlessly across all chains without requiring ETH. Users can easily manage multiple wallets in a single interface, track the signer types for each wallet, and 'burn' wallets after specific actions - never having to worry about them again.

The solution lies in the perfect balance of UX and security. By harnessing Account Abstraction's flexibility, we empower users to manage their wallets exactly how they want.

This project is not technically complex - we combine simple services and focus on UX to make it easy for everyone to use. Breakdown of Main Functionalities

AA Wallet Providers (The Magic): Zerodev and Biconomy provide passkey or ECDSA signer functionality and enable batching transactions, paying transaction fees with tokens, and custom gas sponsorship.

Wallet Token Balance and History - 1inch API: Managing multiple tokens and addresses can be messy. 3rd party APIs come in handy to detect any tokens in burner wallets, ensuring users don't accidentally delete wallets with value. The history API provides extra information about whether a wallet is being used.

Subdomain Registration - ENS: Allows users to easily name their burner wallets, making it simpler to receive money.

Cross-chain Swap/Payment - Across V3: Across is the easiest to use for contract integration and has the highest liquidity plus a solver network to guarantee very fast cross-chain payments. Since AA wallets can batch transactions, using a fully "on-chain" solution like Across won't cause any UX issues.
