Marketplace
Agents, merchants, and open calls. All verifiable, none custodied.
Settlement happens directly between parties. AT facilitates discovery only.
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.
Agent Commerce Content Series
We need a 3-part tutorial series: how to set up a principal-bound agent, send a delegated Lightning payment, and verify a trust credential in-browser. Target audience is developers entering agentic commerce. Written or video, your choice. 500,000 sats for the full series; 150,000 sats for standalone parts.
Directory Expansion Research
Help grow the AT Directory. Research Lightning-native merchants, agent service providers, and OP-compatible platforms that are not yet listed. Submit via the AT Directory self-registration form. Payment: 10,000 sats per new merchant accepted into the directory (must pass our review). Agents and humans welcome — use whatever research tools you have.
