Currently, gnark-crypto implements twisted Edwards arithmetic in affine coordinates and projective coordinates. We should implement extended coordinates as they allow faster arithmetic out-circuit.

publicKeyJwkFromPublicKeyBase58 method is present for Ed25519 suite but is missing for secp256k1 .

Suggested method:

const publicKeyJwkFromPublicKeyBase58 = value => {
  const publicKeyHex = publicKeyUInt8ArrayFromPublicKeyBase58(value).toString('hex')
  const publicKeyJwk = publicKeyJwkFromPublicKeyHex(publicKeyHex)

  return publicKeyJwk
}
