RIP-7212 Onboarding
Using Coinbase Smart Wallet, I created an onboarding demo where users do not need to install any extension, store any seed phrases, or pay any gas fees while maintaining a top level of security of their wallet's private key using a combination of RIP-7212 and EIP-4337.
Project Description
It's a demo showcasing a seamless onboarding experience powered by two key improvement proposals; RIP-7212 and EIP-4337.
It generates a new public-private key pair using the secp256r1 curve, then deploys a smart contract wallet using EIP-4337 with the functionality to verify signatures on the secp256r1 curve using the precompile added in RIP-7212.
How it's Made
I built a simple frontend application with Next.js, Typescript, shadcn/ui.
For the web3 aspects such as connecting wallet and minting NFTs, I used thirdweb.
Thirdweb has an integration with Coinbase smart wallet to power the onboarding experience, creating new wallets that follow the secp256r1 curve, and deploying smart wallets with EIP-4337.
For gasless transactions, I used Base which sponsors the fees of smart contract wallets on the Base Sepolia testnet.
