What FixedFloat is
FixedFloat is a registration-free instant exchange that swaps between a broad set of cryptocurrencies and is well known for Bitcoin and Lightning Network support. It ranks fourth of the 15 instant exchangers we track. You start a swap without an account and receive funds at your own address.
The swap mechanism
Pick a pair, send your deposit, and FixedFloat delivers the counter-asset, taking short-term custody in between. Fixed-rate and float-rate options are common in this category; the rate type determines whether a market move during confirmation is absorbed by you or the operator. Either way, you send first, so the service's reliability is the thing that matters most.
Our measurements
- Track record: roughly eight and a half years of operating history by our records.
- Latency: our probe recorded responses around 171 ms.
- Status transparency: we found no dedicated public status page.
A candid security note
FixedFloat was the subject of a widely reported security breach in early 2024 in which attackers drained a significant amount of crypto. The service resumed operating afterward, but the incident is a real part of its history and a reminder that instant exchangers hold hot funds and are targets. We are not stating current security posture beyond what we measure; treat this as context, not a verdict.
Why hot-wallet exposure matters here
Instant exchangers keep working capital in hot wallets so they can fill swaps immediately. That is what makes them convenient and also what makes them targets, as FixedFloat's own history shows. The lesson for users is behavioural: the less time your funds spend inside any swap service, the smaller your exposure. Complete the swap, withdraw to a wallet you control, and avoid batching large value through a single transaction when smaller ones will do.
Who it suits
It appeals to users who want quick, no-signup swaps, especially involving Bitcoin or Lightning. Given the breach history and the absence of a public status page, cautious users should keep amounts modest, move funds out promptly, and avoid leaving value parked with any instant exchanger.
