Ethereum Account Abstraction

👨‍💻 I built a proof-of-concept using AA and Passkey that enables on-chain operations through your mobile browser — no installation from App Store or gas payments. Check out the live demo:

📱 You can create an on-chain wallet with just your mobile's Face ID or fingerprint reader. Give it a unique name, hit "Create Account," and authorize the tx https://github.com/Detoo/passkey-wallet-poc/raw/main/res/demo.gif

💡 No gas fees or app installations needed. Feel free to try it out rn on your phone; it's running on Base Goerli testnet with sponsored gas from 
Pimlico — appreciate their support!

💸 Upon account creation, you’ll have 100 TEST tokens ready to send anywhere: any address or lookup by wallet name. Try sending 1 token to "detoo"; might send 2 back 🤣.

📬 Get token receipt notifications through PWA. Open the demo in Safari, save it to your home screen, and enable notifications like a native app. https://github.com/Detoo/passkey-wallet-poc/raw/main/res/demo-pwa-notification.gif

I’ve enjoyed how easy it is now to build a lightweight dapp, but this demo wouldn’t be possible without the amazing works from other builders. Shout out to:

Pimlico for their easy-to-use infra on ERC4337 Account Abstraction and sponsoring gas for devs!

Try the demo: https://passkey-wallet-poc.detoo.info and feel free to share your thoughts! 🚀

From Daimo’s doc it currently costs 332k gas to verify; however if EIP-7212 is implemented it would cost only 3.4k!

Here’s a real tx with including P256 verification and a token transfer: https://goerli.basescan.org/tx/0x96718397725e4555d7ab897d87c7bc260535388a71b0fd78862383e506c1e5f3

It's awesome! How much gas does P256 verification take?
