What is the Relayer?

The Relayer is a trusted middleware service that acts as the bridge between users, applications, and the blockchain using the Action Codes Protocol. It enables:
  • Secure registration of action codes
  • Storage of encrypted code state (e.g., pending/resolved/finalized)
  • Status resolution via code hashes (never raw code)
  • Code usage verification, metadata injection, and expiration enforcement
  • Seamless UX with APIs for attaching and finalizing transactions
This allows applications to:
  • Never store private code values
  • Use short, secure, and shareable codes
  • Outsource protocol validation and persistence to a lightweight server

​
Why It Matters

  • Security: Encrypted code state stored by hash only
  • Flexibility: Works with any wallet or frontend
  • Trust Layer: Prevents invalid or spoofed transactions
