Fees: Fixed ~1% / float ~0.5% + network fees
Attractive for its transparent fee display and Lightning support, appealing to Bitcoin-centric users. The serious 2024 exploit weighs heavily on trust, so favor small amounts and don't leave value resting on the platform.
What FixedFloat Is
FixedFloat is an instant crypto exchanger operating since 2018, known for account-free swaps and native support for the Bitcoin Lightning Network. Its name comes from its two modes: a fixed rate that locks your quote and a floating rate that tracks the market until settlement. You get a deposit address, send your coins, and receive the converted asset in your wallet, with no registration required.
How It Performs
FixedFloat scores well on the mechanics and poorly on trust. Fee transparency and speed both hit 8: it displays an explicit percentage fee and settles quickly on supported pairs. Rates sit at 7 and asset coverage at 7, both solid if not class-leading. The glaring number is trust at 5.5, by far the lowest in this group, a direct reflection of the serious 2024 security incident that shadows the platform.
What It Costs
FixedFloat is refreshingly clear about pricing: the fixed-rate mode carries a fee around 1% and the floating mode roughly 0.5%, with network fees on top. Showing the percentage explicitly, and the difference between the two modes, is a genuine plus and the main reason its fee-transparency score is high. You can weigh the certainty of a fixed rate against the lower cost of a floating one knowing exactly what each will charge.
The Main Caveat
Trust is the issue that overrides the rest. FixedFloat suffered a major security breach in February 2024, with a reported figure around $26M stolen, and any instant exchanger carries custody exposure while a swap is in flight. Together those factors justify keeping amounts small and never leaving value resting on the platform. Move funds through promptly and treat it as a pass-through, not a place to hold crypto.
Who It's For
FixedFloat appeals most to Bitcoin-centric users who want Lightning support, transparent fees and fast settlement, and who are comfortable transacting in small amounts. If those features matter to you and you size positions cautiously, it has real strengths. Anyone prioritizing a spotless security record, or moving large sums, should think hard given the 2024 exploit.
Overall 7.1 / 10 — the weighted average of the criteria above. How we score →
- + Explicit percentage fee shown clearly (fixed vs float)
- + Native Bitcoin Lightning Network support
- + Fast settlement on supported pairs
- + No account required
- − Suffered a major security breach in February 2024 (~$26M reportedly stolen)
- − Custody exposure while a swap is in flight raises risk
- − Coverage narrower than the largest aggregators
Is FixedFloat safe after the 2024 hack?
+
FixedFloat suffered a major security breach in February 2024, with roughly $26M reportedly stolen, and that incident drives our low 5.5 trust score. The platform continues to operate, but any swap involves custody exposure while it is in flight. The prudent approach is to use small amounts and avoid leaving value on the platform.
What are FixedFloat's fees?
+
FixedFloat shows an explicit percentage fee: around 1% for the fixed-rate mode and roughly 0.5% for the floating mode, plus network fees. This clear display earns it an 8/10 for fee transparency, one of the better marks in our review.
Does FixedFloat support the Lightning Network?
+
Yes. Native Bitcoin Lightning Network support is one of FixedFloat's defining features, which makes it appealing to Bitcoin-centric users who want fast, low-cost BTC swaps. Settlement on supported pairs is quick, in line with its 8/10 speed score.
Does FixedFloat require an account?
+
No. Standard swaps need no registration. You choose fixed or floating, provide a receiving address, and send your deposit. Bear in mind that no-account convenience does not remove the custody risk that exists while a swap is processing.
What is the difference between FixedFloat's fixed and float rates?
+
The fixed rate locks your quote so the receive amount is guaranteed, at a fee around 1%. The float rate tracks the market until settlement at a lower fee near 0.5%, meaning the final amount can move up or down. Fixed favors certainty; float favors cost.
