This post is about the PIP-27, migrated from the EIP-7212, and proposes adding a new precompiled contract to the EVM that allows signature verifications in the “secp256r1” elliptic curve by given parameters of message hash, r - s components of the signature, and x - y coordinates of the public key.
We believe that its inclusion in the Polygon mainnet is valuable to enhance user and developer experiences by maximizing security for this elliptic curve’s operations. Polygon has one of the most adopted ecosystem of account abstraction and this precompiled contract contributes to this ecosystem in many areas. Also, this EIP’s inclusion to other EVM chains before the L1 is encouraged in an ACDE call.
Please follow the discussion and details in the EIP forum:
