## Verdict

FixedFloat is one of the larger no-account instant exchangers and one of the most-cited routes for BTC ↔ XMR swaps in the Monero community. The trade-off is the well-documented AML screening: a portion of users are asked for ID before their swap output is released, and the criteria are not transparent. Use a fixed-rate quote on tested routes and assume some swaps will be held for review.

## Strengths

- Wide asset coverage including Lightning, with both fixed-rate and floating-rate modes.
- Order-status page is detailed enough to debug stuck swaps without contacting support.
- No mandatory signup for the standard quote-and-swap flow.

## Caveats

- In February 2024 FixedFloat disclosed an exploit that drained roughly $26M in BTC and ETH from its hot wallets; downstream effects on screening and review windows have persisted.
- Holds with KYC-to-release have been widely reported across instant-exchanger reviewers; the screening provider and triggers are not public.
- Facts need re-verification by operator (last seeded 2026-01).

## What FixedFloat is

A no-account instant exchanger. Both fixed-rate and float-rate orders are offered; the fixed rate locks the conversion at order time and the float rate adjusts to the market when the deposit confirms. Lightning is supported on the BTC side.

## Threat-model fit

FixedFloat occupies the middle of the no-KYC instant-swap spectrum: better-than-most asset coverage and UX, but custodial during the window and subject to AML screening on output. Common community guidance is to route from a CEX (or from a privacy-untrusted source) into Monero, churn, and then swap out — putting FixedFloat on the *exit* leg rather than the entry.

## Recent changes

The 2024 incident shifted the operator's risk posture; expect tighter screening on outliers and on flagged input addresses. Treat large-amount routes as more likely to trigger review.
