OP Integration Challenge

Add Observer Protocol trust credential verification to any Lightning-enabled service, wallet, or agent. We want to see real integrations: fetch a MerchantTrustCredential, verify the eddsa-jcs-2022 signature, gate actions on the result. Winning submission earns a Tier 2 listing in the AT Directory, a co-authored case study, and the prize.

WDK + OP Reference Demo

Build a working demo that shows a WDK-enabled wallet enforcing an Observer Protocol TradingMandate credential. The demo should: load a mandate from a did:web, evaluate a transaction against it, and show pass/fail with the verification trace. We will publish it as the canonical WDK+OP reference implementation and list the builder in the directory.
