CRYPTOGRAPHY: P256 & RSA
We have incorporated well-known cryptographic primitives that enable builders to create applications on top of real-world infrastructure.
Among the new additions, users will find the P256 and RSA libraries for signature validation ✍️


CRYPTOGRAPHY: Merkle Tree
We also introduced a new MerkleTree library for onchain trees and updated MerkleProof to support custom hash functions
These additions unlock exciting possibilities, from using consumer hardware like Apple’s Secure Enclave to powering smart accounts 🧠
