OP-verified merchants on the rails Bitcoin and Tether actually use

The Open Agentic Commerce Merchant Directory

AT Directory is the open agentic commerce merchant directory for the rails that move real commerce — Lightning, BOLT12, L402, and USDT on any chain — with verifiable trust attestations issued through Observer Protocol. Tether is bringing USDT onto Lightning via Taproot Assets; we index these rails honestly, and agents transact accordingly.

Trust tiers — derived from verifiable attestations, not self-reported:

◈ Tier 1Self-attested — the merchant’s own claim.

✓ Tier 2Verified by 1+ counterparties — OP-credentialed agents attested real transactions.

✓ Tier 3OP-native, counterparty-verified — the merchant runs Observer Protocol.
