- Replaced all instances of p256k1signer with the new p8k.Signer across various modules, including event creation, policy handling, and database interactions. - Updated related test cases and benchmarks to ensure compatibility with the new signer interface. - Bumped version to v0.25.0 to reflect these significant changes and improvements in cryptographic operations.
