FixedFloat Alternatives for Instant Crypto Swaps (2026)

FixedFloat is a well-known instant exchanger with a Bitcoin-centric culture and a fixed-rate option. People look for alternatives when they need Monero depth, USDC on Base, a Telegram bot, or a published service fee they can explain to someone else. This page compares options without pretending Swap.bz wins every column.

Method

• Same pair and a mid-size amount — never compare 50-coin catalogs as if they were one product.
• Read the receive amount after all fees, not the homepage slogan.
• Check send network, refund address rules, and whether Lightning or XMR is actually listed.
• Note AML screens: “no KYC to create a quote” is not “never any check”.

Where FixedFloat still wins

Lightning and a long-running BTC-native UX. If your whole workflow is BTC in/out on Lightning with a locked quote, FixedFloat may remain the better fit. Swap.bz does not claim feature parity there.

Swap.bz as an alternative

• 0.5% Standard / 1% Private published in the widget
• Native XMR pairs and optional multi-hop Private routing
• USDC/USDT across Base, Ethereum, Tron, Solana — network must match
• Web widget plus @SwapbzBot
• Narrower long-tail altcoin list than ChangeNOW

Other names

ChangeNOW: larger altcoin catalog, fee often inside the rate. SideShift: clean UI, optional account for history. StealthEX: wide list — watch Ethereum gas on small sizes. Always quote the same amount on the same day.

When to stay or switch

1. Need Lightning BTC loops → start with FixedFloat.
2. Need BTC→XMR or USDC Base→SOL without an account → quote Swap.bz.
3. Need an obscure alt → a larger catalog may be required.
4. Write down the receive amount. That number is the comparison.
