BSV Message Signing
Three approaches for message signing on BSV, from simple to full-featured.
Quick Reference
| Approach | Package | Use Case |
|---|---|---|
| Direct SDK | @bsv/sdk |
Simple message signing (BSM, BRC-77) |
| Templates | @1sat/templates |
Script parsing/creation for protocols |
| Sigma Protocol | sigma-protocol |
Transaction-bound signatures |
1. Direct SDK Signing
For simple message authentication without transaction context.
