| The secp256r1 (P-256) elliptic curve is the standard cryptographic curve used by modern device security systems, including Apple's Secure Enclave, Android Keystore, WebAuthn, and Passkeys. However, Avalanche currently only supports secp256k1 natively, forcing developers to use expensive Solidity-based verification that costs [200k-330k gas per signature verification](https://hackmd.io/@1ofB8klpQky-YoR5pmPXFQ/SJ0nuzD1T#Smart-Contract-Based-Verifiers). | |||

There was a problem hiding this comment.
This is the incorrect gas cost if we're following 7951.

RIP-7212 is superseded by EIP-7951 due to some security vulnerabilities discovered. Go-ethereum already implemented and merged the EIP.
There seems no issue of compatibility other than increased gas cost (3450 in 7212 vs 6900 in 7951)
EIP-7951 is still in status: Draft, but I think it will eventually supersedes 7212.
