First, the honest version: FixedFloat is one of the older instant-swap services around (running since 2018), it still works, and its Bitcoin Lightning support is genuinely good — CoinDesk simply calls it a "Bitcoin Lightning exchange". A fair comparison starts by admitting that. Whether switching is worth it depends on how much weight you give the three documented reasons below.

Why people look for a FixedFloat alternative — the documented reasons

Reason 1 — the 2024 security incidents

In February 2024, FixedFloat was hacked for roughly $26 million — about 409 BTC and 1,728 ETH — which the team confirmed on its own blog ("our system was hacked… $26.1 million was stolen"). In early April 2024 a second drain of roughly $2.8–3 million followed, reported by CoinDesk and attributed by researchers to the same attackers. FixedFloat stated user funds were unaffected because the service is non-custodial, and it resumed operation with a reduced coin list before rebuilding.

Both events are public record. How much weight to give a two-year-old incident that didn't touch user balances is a judgement call — but an exchange being drained twice in two months says something about the security posture at the time, and it remains the single most common reason this search exists.

Reason 2 — verification can still happen mid-swap

FixedFloat's own Terms of Service reserve the right to suspend an order and "conduct KYC and SoF procedures" (§6.5), to require identity verification before a refund (§7.9), and to freeze funds connected to criminal sources (§6.2, §7.8). In March 2025 it went further, publicly declaring all funds connected to one uncooperative exchange "criminal" and subject to automatic holds. That's why the independent directory kycnot.me classifies it as "Shotgun KYC" (level 3 of 4) and scores it 4/10 as of July 2026, with warnings including "may freeze or seize funds" and "refunds may require KYC" — and why a community megathread on BitcoinTalk catalogues freeze cases from about $1,000 to over $8,000.

Context matters here: clauses like these exist across most of the instant-swap industry (we explain the whole pattern in our shotgun-KYC guide). The practical difference between providers is how often the trigger fires, what the resolution feels like — and whether the provider runs such screening at all.

Reason 3 — swap-only, and not available everywhere

FixedFloat handles crypto-to-crypto only: no way to buy with a card, no way to cash out to a bank. Its terms also prohibit use by US persons and anyone in UN-sanctioned countries. So if your real workflow is "get money in, swap around, sometimes cash out", FixedFloat can only ever be one piece of it, and you're juggling multiple services either way.

What to demand from any alternative

Whatever you evaluate — including us — run it through these five checks. They take ten minutes and they're where the real differences hide:

FixedFloat vs AceChange — the factual comparison

Read that table the way we would. On the pure swap mechanics, the two are close — same rate structure, no account either way, Monero on both. The separation happens on three rows: the KYC/AML row (FixedFloat reserves it and uses it; AceChange doesn't run it at all), the incident row, and everything around the swap — fiat on/off-ramp with a no-ID tier, free tools, anonymous alerts and a Telegram-native flow. Against that, FixedFloat keeps two honest wins: two extra years of history and its Lightning implementation. If Lightning is your daily rail, that row alone may decide it; for everyone else, the value concentrates on the left half of the table.

Other FixedFloat alternatives worth knowing about

A fair "alternative" page should name more than itself, so: Trocador (kycnot.me 8/10) is a privacy-focused aggregator that quotes many swap engines and grades each partner's KYC behaviour A–D — the right tool if your priority is shopping every swap around and routing past strict compliance desks. StealthEX and ChangeNOW are the closest like-for-like instant swappers, but both carry the same shotgun-KYC classification as FixedFloat (4/10 and 5/10 respectively), so they solve reason 3 at best — not reasons 1-adjacent trust or the verification problem. And if you want verification to be structurally impossible rather than just absent, P2P platforms like Bisq and RoboSats (both 10/10) are the endgame, at the cost of premiums and slower trades. Our full swap-site comparison covers all of them with sources.

Switching in practice — three steps

1. Test with a small amount first. Run a $20–50 swap end to end on any new service before you trust it with anything meaningful. This is the single best piece of advice in this niche and almost nobody follows it.
2. Check the receive details before funding. The exact output amount, the network and your address are shown before you send — wrong-network transfers are unrecoverable everywhere, on every service.
3. Keep your own records. Save the order ID and the tracking link. With no account, that link is your proof and your support ticket.

Frequently asked questions

Is FixedFloat still safe to use in 2026?
It operates normally and its 2024 incidents didn't touch user funds, by its own account and available reporting. "Safe" in this industry means non-custodial exposure measured in minutes, disclosed policies, and a track record — FixedFloat has all three, alongside the documented history and ToS clauses above. Draw your own line; this page exists to give you the dated facts either way.

What is the best FixedFloat alternative?
For most people: the alternative that removes both of FixedFloat's real friction points at once — mid-swap verification risk and the missing fiat rail. AceChange does both (no KYC/AML on swaps ever, plus a no-ID fiat tier) at the same headline rates. If your one priority is Lightning, stay put or use both; if it's absolute structural privacy, go P2P.

Is AceChange cheaper than FixedFloat?
No — and we won't pretend otherwise. The headline rates are identical: 0.5% floating, 1% fixed. The comparison is about the KYC/AML difference and scope (fiat buy/sell, tools, alerts, Telegram), not price. For any specific pair, compare the receive amounts side by side — that's the only number that matters.

Do I need an account to switch?
No. AceChange swaps work with no account and no email: pick the pair, paste your receive address, send the deposit. A typical swap completes in 5–30 minutes, and the exact amount you'll receive is shown before you commit.

Does AceChange ever ask for KYC on swaps?
No. AceChange runs no KYC and no AML screening on crypto-to-crypto swaps — no account, no identity, at any amount. (The optional fiat buy/sell side works through a regulated payment partner with a tiered system whose Level 1 needs no ID document — that's a separate, clearly-marked rail.)
