FixedFloat
6.7/10 total
One of the oldest and highest-volume instant swappers, with Bitcoin Lightning support that makes BTC to XMR routes unusually fast. Its reputation is split: excellent rates and uptime, but a well-documented pattern of AML holds on larger transfers, and it lost roughly $26M to a hot wallet breach in February 2024.
Scores
Weights are published in the method and applied identically to every entry.
For
- Long operating history and deep liquidity
- Lightning Network support for fast, cheap BTC legs
- Low headline fees on both rate types
Against
- Risk-based KYC: large or flagged swaps can be held pending verification
- Suffered a ~$26M hot wallet compromise in February 2024
- No onion service, and the site requires JavaScript
Agent access 6/10
Well-documented public API including Lightning routes, but production access is issued per partner account.
Reported separately and not counted in the total. It measures what an autonomous agent can do unattended, not whether the service is safe to use.
Fees
0.5% float / 1.0% fixed
Plus network fee. The headline rate is genuinely competitive; the risk is not priced in the fee.
