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
- Need Lightning BTC loops → start with FixedFloat.
- Need BTC→XMR or USDC Base→SOL without an account → quote Swap.bz.
- Need an obscure alt → a larger catalog may be required.
- Write down the receive amount. That number is the comparison.
Frequently asked questions
What is a good FixedFloat swap alternative?
If you need on-chain majors, Monero, or published fees, quote Swap.bz (0.5% Standard / 1% Private). For Lightning-native BTC loops, FixedFloat may still be the better tool.
Is Swap.bz cheaper than FixedFloat?
Compare the final receive amount for the same pair and size. Swap.bz publishes 0.5% Standard / 1% Private. FixedFloat uses floating or fixed quotes with an embedded spread. Neither is cheaper on every route.
Does Swap.bz support Lightning like FixedFloat?
FixedFloat is stronger for Bitcoin Lightning-native flows. Swap.bz focuses on on-chain cross-chain pairs, Monero, and multi-network stables. Pick the tool that matches the rails you actually use.
