We requested live quotes for native BTC to USDT, and back, from [L2Pass Swap](https://swap.l2pass.com/) and other cross-chain services, on October 19, 2026, with the same amounts for every provider. For 0.01 BTC to USDT, on Tron and on Ethereum, L2Pass RFQ by NEAR Intents returned the most USDT, and side by side in the web interfaces it beat the THORChain app on every pair, in regular and private mode. For 1,000 USDT on Tron to BTC, Relay returned the most BTC. The L2Pass fee on BTC swaps is up to 0.2%, included in every amount below.

## Instant exchanges through Trocador

[Trocador](https://trocador.app) compares instant exchanges such as FixedFloat, StealthEX and ChangeNOW. We requested the same swaps there between 18:32 and 18:34 UTC. L2Pass quotes for BTC to USDT on Tron were refreshed at 18:28 UTC for comparison.

| Exchange (Trocador rating) | 0.01 BTC to USDT on Tron | 0.01 BTC to USDT on Ethereum | 1,000 USDT on Tron to BTC |
| :- | :- | :- | :- |
| **L2Pass RFQ** | **814.53 USDT** | 817.29 USDT (18:21 UTC) | 0.01215845 BTC (18:21 UTC) |

Trocador shows BTC amounts to five decimals.

Trocador's privacy rating (A to C here) reflects each exchange's terms, privacy policy and refund practice when a user refuses verification. Trocador notes that any exchange can still pause a swap and ask for KYC or AML checks. Floating amounts are estimates and are re-priced when your deposit confirms; fixed amounts are locked.

## Interface check: L2Pass vs the THORChain app

Checked side by side in both web interfaces on October 19, 2026, at about 18:50 and 19:05 UTC. The THORChain app offers a regular swap and a private swap powered by Houdini Swap.

| Swap | L2Pass | THORChain app | Difference |
| :- | :- | :- | :- |
| 0.01 BTC to USDT on Tron, regular | **817.11 USDT** (L2Pass RFQ, about 14 minutes) | 814.86 USDT (about 11 minutes) | +2.25 USDT on L2Pass |
| 0.01 BTC to USDT on Tron, private | **813.43 USDT** (L2Pass Private, about 14 minutes) | 804.88 USDT (Houdini Swap, about 15 minutes) | +8.55 USDT on L2Pass |
| 1,000 USDT on Ethereum to BTC, regular | **0.01216000 BTC** (L2Pass RFQ, about 8 minutes) | 0.0121513 BTC (about 11 minutes) | +0.0000087 BTC on L2Pass |
| 1,000 USDT on Ethereum to BTC, private | **0.01212596 BTC** (L2Pass Private, about 8 minutes) | 0.0120086 BTC (Houdini Swap, about 16 minutes) | +0.0001174 BTC on L2Pass |

At the time of the check, the THORChain app said swaps without a connected wallet were paused, so a Bitcoin wallet had to be connected. L2Pass accepts BTC from any wallet or exchange through a one-time deposit address.

## What the numbers show

* **L2Pass beat the THORChain app on every pair we checked in both interfaces,** in regular and private mode. Relay returned the most for USDT on Tron to BTC.
* **Tron delivery costs vary a lot.** THORChain charged a 3.36 USDT outbound fee to Tron, and L2Pass charged 1.71 USDT.
* **Instant exchanges cost more.** ChangeNOW and SideShift returned 4 to 24 USDT less on 0.01 BTC.
* **Bitcoin confirmations set the pace.** Every native BTC swap waits for Bitcoin blocks, so a 4-second relayer still takes minutes in total.
* **Private swaps cost more everywhere, but less on L2Pass.** L2Pass Private returned 8.55 USDT more than Houdini Swap in the THORChain app.

## Which one to use

* **BTC to USDT on Tron:** L2Pass RFQ returned the most and accepts BTC from any wallet or exchange.
* **BTC to USDT on Ethereum:** L2Pass RFQ returned the most of the providers we checked.
* **USDT to BTC:** Relay returned the most in our test. L2Pass shows Relay's routes where Relay supports the pair.
* **Private BTC swaps:** L2Pass Private.
