# Taproot Assets

> [!info] This is the *exchange* lens of Taproot Assets. For the protocol/integration view — issuing and moving assets, running `tapd` — see its [tools card](/tools/taproot-assets).

**What it is.** Not a venue but a **protocol-level FX capability**: Taproot Assets turns Lightning into a *decentralized foreign-exchange network*, so an agent can pay in sats and a counterparty can receive a stablecoin (or vice versa) over Lightning. **USDT has been live on Lightning via Taproot Assets since March 2026.**

**What it bridges.** **BTC / Lightning ↔ USDT** (and other issued assets), converted in-flight. There is no bank-fiat leg.

**How the swap works.** Conversion happens at the **routing layer via edge nodes** — any Taproot-Assets-aware Lightning node can act as one. Before an invoice is generated, the parties agree an exchange rate (each edge peer sets its own, competing on rate/fees); the payment then routes through asset channels, and the receiver validates it got the expected asset amount. It's a swap embedded in a Lightning payment, not a trip to an exchange.

**Agent access *(limited)*.** There is still **no clean hosted REST swap API** like Boltz's. An agent needs `tapd` (or a Taproot-Assets-capable wallet) and Taproot Assets channels with edge nodes that quote the pair. The **v0.8 release (2026-06) + its SDK and RFQ (request-for-quote) improvements** make developer integration easier and the quote/liquidity flow more automatable — real movement — but the path is still node-plus-integration, not a turnkey API call, so the rating holds at *limited*. Weigh it against Boltz/Flashnet for autonomous use.

**Dependencies.** A Taproot-Assets-capable Lightning stack (`tapd` + compatible Lightning Terminal; v0.8 SDK for builders) and a channel/peer that provides asset liquidity for the pair. Self-custodial; no account, no KYC at the protocol layer.

**Gotchas.** **Rails, not substrate.** The rail-side properties are excellent (Lightning fees, Lightning speed), but **the asset is unchanged: USDT-on-Lightning still carries Tether's issuer freeze surface** — censorship-resistance is satisfied or not *at the asset layer*, and a regulated stablecoin does not satisfy it. Edge-node liquidity for a given pair may be thin or absent. `tapd` is still alpha-stage on mainnet per Lightning Labs' own safety docs — read the Operational Safety Guidelines first.
