What it is. Amboss’s Lightning-native, peer-to-peer decentralized exchange (launched January 2026), executing bitcoin ↔ stablecoin trades entirely over the Lightning Network — no separate chain and no custodial order book.

What it bridges. Bitcoin ↔ stablecoins, connecting those pairs toward the global FX market. (Confirm the exact supported pairs on the venue — the asset list above reflects the Amboss stack’s stablecoins and should be re-verified.)

How it works. Trades execute as circular self-payments: funds route out through existing Lightning channels, swap atomically, and loop back to the sender — so either the swap completes or it doesn’t, with no custody handover in between.

Agent access. No public trading API is documented yet — the venue is app/flow-driven for now. Carded here for reference; it sits below the directory’s machine-actionable bar until a programmatic path is published.

Custody. Self-custodial / Lightning-native — you trade from your own channels, not a venue-held balance.

Dependencies. Lightning capacity to route the swap and a self-custody wallet/node. Verify supported pairs, fees, and regional availability on the venue.

Gotchas. The atomic Lightning execution protects custody (you don’t hand funds to a counterparty mid-swap) — it does not make the stablecoin legs censorship-resistant: USDT/USDC remain issuer-freezable by Tether/Circle. New as of January 2026; no public API yet; confirm pairs, fees, and availability before relying on it.
