solana-keychain v0.3.0 just dropped, now with native Google Cloud KMS support!
If you're building production-grade Solana applications (relayers, bots, DeFi protocols, institutional tools, etc.), secure key management is always one of the biggest pain points.
solana-keychain gives you a clean, unified Rust (and TypeScript) interface to sign transactions across multiple secure backends, without rewriting signing logic every time you change environments.
What's new in v0.3.0:
๐งโ๐ป โจ Google Cloud KMS integration, keep your Ed25519 keys safely in GCP, never on your servers
๐งโ๐ป Zero local key exposure in production
๐งโ๐ป Async-first design, feature-gated backends (add only what you need โ tiny dependencies)
