Hey all, just wanted to share a nice new feature coming in next week’s agent-js 0.10.0 release! The 0.10.0 release will include the Buffer refactor, which has been available on the 0.10.0-beta.1 release, as well as support for secp256k1 public keys and identities.

This will enable identities created from bitcoin-compatible seed phrases to be used to sign calls to the IC. Please use this feature responsibly and keep your users’ secret keys safe!
