Pixel is an ERC-4337 account implementation and Optimistic Rollup that turns every modern smartphone on the planet into a hardware wallet, eliminating the security risks and poor user experience associated with manual private key management. All modern smart phones contain a Hardware Security Module that can securely create ECDSA keypairs and use them to generate signatures along the P256 (secp256r1) curve. However, EVM based blockchains do not natively support signature verification along the P256 curve - they use the Koblitz (secp256k1) curve instead. This makes it impossible use smart phone HSMs to sign Ethereum transactions, even though they are ideally suited for this purpose. Pixel overcomes this limitation by implementing P256 signature validation on-chain and using it to validate ERC-4337 account transactions. This approach gives every ECDSA P256 public key a unique Ethereum account address that can be used across any EVM blockchain where Pixel is deployed (currently Goerli, Gnosis Chain, Scroll, and Polygon ZK EVM). Since on-chain solidity-based P256 signature verification can be very gas-intensive (500k-1M gas), Pixel also provides its own Optimistic Rollup that natively supports P256 signature verification using a custom precompile. By verifying signatures natively, Pixel Rollup reduces gas costs for Pixel Wallet transactions by over 92% compared to Goerli. Combined together, Pixel Wallet and Pixel Rollup can help scale Ethereum by putting a gas-efficient, hardware-secured, and user friendly Ethereum wallet in every pocket. Pixel was built during the Scaling Ethereum 2023 Hackathon by @jaydenwindle and @hwrdtm.
