REAL — Cowrie Exchange (Lagos, Nigeria), issuer of NGNT. Confirmed 2026-10-17 by @corridor/probe against the anchor's live production API: SEP-10 challenge signed and exchanged for a JWT, SEP-12 answered, and SEP-31 GET /info returned a non-empty receive list (NGNT, USDC). No SEP-38 quote server is published, so pricing is off-protocol (quote_source=external) — this corridor cannot get a firm on-chain quote today. No payment has been attempted; a real settlement still needs a KYC'd business relationship with Cowrie, which this repo does not have.

Liveness warnings

fx.quote_source=external requires an external quote provider to be wired by the operator; it is not covered by endpoints_verified_at.
recovery.timeout_seconds (900s) does not exceed recovery.reconcile.external_stall_seconds (21600s); the corridor timeout will end pending_external/pending_receiver waits first. Raise timeout_seconds for corridors that need the full external stall budget.
