FixedFloat

FixedFloat is a non-custodial instant crypto exchange that is built for one thing, swapping one asset for another without opening a conventional exchange account. You choose a pair, receive a deposit address, send the coins, and receive the output to your own wallet. It has long appealed to users who value speed, no routine identity check, and a stripped-down interface.

The service is not a traditional exchange despite the name. There is no visible order book, no fiat balance, no margin account, and no place to park a portfolio. FixedFloat acts as a swap intermediary, sourcing conversion liquidity and settling the output transaction. That makes it convenient, but it also means you must judge the quoted rate, network conditions, and the platform's operational trustworthiness in a matter of minutes.

Its defining feature is the choice between a floating rate and a fixed rate. The floating option has historically carried a 0.5 percent service fee, while the fixed-rate option has historically charged 1 percent. Network fees are added separately. The fixed option is useful in volatile markets because it protects the quoted exchange rate during the swap window, though it costs more and still depends on you sending the exact required amount on time.

A 0.5 percent headline fee is not cheap compared with trading on a liquid centralized exchange. Binance, Kraken Pro, and Coinbase Advanced can be far cheaper for users who are willing to create an account, complete checks where required, and trade through an order book. FixedFloat competes on convenience. For an occasional wallet-to-wallet swap, that convenience can be worth the premium. For frequent trading, it becomes an expensive habit.

The quote also needs close attention. The service fee is just one component of the transaction. The spread between the reference market price and the rate you receive can matter, especially in thin pairs or fast conditions. Bitcoin and Ethereum network fees can also change sharply. Always compare the final amount you will receive with at least one alternative, such as ChangeNOW, SimpleSwap, a decentralized exchange, or an exchange withdrawal route.

Speed is usually excellent when the source chain is moving normally. Many swaps are processed automatically after the required deposit confirmations arrive, and popular asset pairs can complete in minutes. But no instant exchange can make Bitcoin confirmations, Ethereum congestion, wallet broadcast delays, or blockchain reorg risk disappear. The word instant describes the conversion workflow, not a guarantee that every transaction settles immediately.

FixedFloat is particularly suited to users who understand confirmation requirements. A Bitcoin payment may take longer than a Litecoin or Tron transfer. An Ethereum token swap can be held up by gas conditions. Sending a token through the wrong network can turn a quick exchange into a manual support case, and manual support is exactly where anonymous instant exchangers are least reassuring.

The security story is mixed. On the positive side, FixedFloat is non-custodial in the ordinary sense that it does not ask users to maintain a long-term account balance. Funds are sent for a specific swap and then forwarded. That is materially safer than leaving assets on a lightly regulated exchange for months. It does not mean the service is trustless. During the exchange, the provider controls the operational process and users take counterparty risk.

That risk became impossible to ignore in February 2024, when blockchain investigators linked suspicious outflows of roughly $26 million in Bitcoin and Ether to FixedFloat wallets. The service later acknowledged a hack and said it had suffered technical problems. This was a serious incident, not minor downtime. Any review that waves it away because the platform is non-custodial is not taking customer risk seriously.

The practical result is that I would not send a large, time-sensitive amount through FixedFloat unless I had tested the exact pair and had a clear backup plan. The platform may still work well for modest swaps, but its hack history demands a lower trust score than its formerly smooth interface might suggest. Avoid sending funds from an exchange account if you cannot tolerate a compliance inquiry or a delayed destination transaction.

FixedFloat has historically operated without mandatory account registration or standard KYC for ordinary swaps. That privacy is the point for many users. It should not be confused with immunity from compliance controls. Like other instant exchanges, it can request information, halt processing, or review a transaction if its risk systems flag an address or activity. A no-KYC marketing message is not a contractual promise that a transfer can never be questioned.

Reputation is therefore complicated. Before the 2024 compromise, FixedFloat had built substantial recognition among privacy-minded swap users and was often praised for speed. The hack changed the calculation. A provider can recover operationally, but it cannot erase the fact that users now have to account for a major security event and the uncertain burden placed on its incident response systems.

Support is another weak point. The platform's automated flow is excellent when everything proceeds normally, but user reports over the years have shown that difficult cases can be frustrating, particularly around delayed exchanges and compliance reviews. There is no reassuring phone desk or extensive regulated-entity structure behind the service. Keep all transaction IDs, screenshots, deposit hashes, and destination addresses until the swap is fully complete.

FixedFloat remains useful, but it is no longer a service I would recommend casually. Its fixed-rate option is genuinely practical, its interface is simple, and routine swaps can be fast. The 2024 hack and the inherent opacity of no-account instant exchanges put hard limits on that praise. Use it for a small, deliberate swap if its final quote is compelling. For large transfers or money you cannot afford to have delayed, choose a more accountable route.
