Introduction

MetaKeep Cryptography Services provide a secure and accessible platform for generating and using asymmetric signatures based on the BabyJubJub elliptic curve.

BabyJubJub is a zk-SNARK-friendly elliptic curve that is used in the Polygon ID standard. Here are the technical specifications of the curve supported by MetaKeep:

Curve: BabyJubJub Elliptic Curve
Signature scheme: Uses EdDSA as defined in RFC 8032
Hash function: Message is hashed using Poseidon hash function.

The signatures and public keys generated by MetaKeep for the BabyJubJub curve are fully compatible with the Polygon ID standard.
