Conclusion
FixedFloat carved out a niche as the first instant swap to support Bitcoin's Lightning Network—and that's still its biggest draw. Lightning swaps are near-instant and dirt cheap. The broader platform handles 68 cryptocurrencies with no registration, no KYC, and no custody of your funds. Fees run 0.5% for floating rates, 1% for fixed. The $1 minimum is the lowest you'll find anywhere. The tradeoff? Limited coin selection compared to competitors like ChangeNOW or Changelly, and zero fiat support. If you're moving Bitcoin fast or swapping between major coins without hassle, FixedFloat delivers. For altcoin variety, look elsewhere.

FixedFloat launched in 2018 with a specific angle: be the first instant swap platform to integrate Bitcoin's Lightning Network. That's still its core strength. Lightning transactions settle in seconds at a fraction of on-chain fees, making FixedFloat the go-to choice for users who move Bitcoin frequently.
The platform operates as a fully automatic, non-custodial exchange. No accounts, no KYC for standard swaps, no holding your funds. You send crypto to a generated address, FixedFloat swaps it, and sends the result to your wallet. The whole process takes minutes—or seconds if you're using Lightning.
With 68 supported cryptocurrencies and a $1 minimum transaction limit, FixedFloat targets users who want speed and simplicity over variety. It's not trying to compete with exchanges listing 500+ tokens. It's built for quick, clean swaps between major assets.
Services and Features
Instant Crypto Swaps
The core product. Select your source and destination coins, enter an amount, provide your receiving wallet address, and send. FixedFloat handles the conversion automatically and forwards your swapped coins. No registration required. The interface is clean—minimal steps, no account dashboards to navigate.
Two rate options: floating (0.5% fee) and fixed (1% fee). Floating rates adjust based on market movement during the swap—you might receive more or less than quoted. Fixed rates lock your price for 10 minutes, protecting against volatility but costing an extra 0.5%. Most small swaps go floating; larger amounts often use fixed for predictability.
Lightning Network Support
This is FixedFloat's standout feature. Bitcoin's Lightning Network is a Layer 2 solution that enables near-instant, low-fee BTC transactions. FixedFloat was the first instant swap to integrate it.
What this means in practice: instead of waiting 10-60 minutes for Bitcoin confirmations, Lightning swaps settle in seconds. Fees drop from dollars to fractions of a cent. If you're swapping BTC regularly—especially smaller amounts—Lightning changes the economics entirely.
You'll need a Lightning-compatible wallet (Phoenix, Muun, Wallet of Satoshi, etc.) to use this feature. The swap interface indicates when Lightning is available for your selected pair.
Supported Cryptocurrencies
FixedFloat supports 68 cryptocurrencies—enough to cover the majors (BTC, ETH, LTC, XRP, SOL, ADA, DOGE) plus popular altcoins. The selection is curated rather than exhaustive. Don't expect obscure tokens or new meme coins.
The focus is reliability over variety. Every listed asset has been vetted for liquidity and stable node operations. This means fewer failed or stuck transactions, but also fewer options if you're chasing long-tail altcoins.
Fees
FixedFloat keeps fees simple:
- Floating rate: 0.5% service fee. Final amount depends on market price at conversion time.
- Fixed rate: 1% service fee. Rate locked for 10 minutes from order creation.
Network fees apply on top—paid to miners/validators, not FixedFloat. Lightning transactions have negligible network fees. On-chain Bitcoin or Ethereum transactions carry standard network costs.
The $1 minimum swap is notably low. Most competitors set minimums at $5-10 or higher. This makes FixedFloat practical for small test transactions or micro-swaps.
Security
Non-custodial model is the primary security feature. FixedFloat doesn't hold user funds in a centralized wallet. Crypto moves through the platform during the swap and goes directly to your destination address. No pooled funds sitting as a hacking target.
The platform runs fully automatic—minimal human intervention means fewer points of failure or internal risk. Standard security practices apply: SSL encryption, secure infrastructure, no stored user data for anonymous swaps.
One caveat: FixedFloat's AML system can flag and freeze transactions suspected of criminal connections. If this happens, you'll be asked for documentation about fund origins. This affects a small minority of users but can cause significant delays if triggered.
KYC Requirements
No KYC for standard swaps. You provide a wallet address, not personal documents. That's the point of the platform.
The exception: transactions flagged by AML monitoring may require verification. This isn't routine KYC—it's triggered by specific risk signals. Most users never encounter it.
How to Use FixedFloat
The process is straightforward:
1. Select source and destination cryptocurrencies
2. Choose floating or fixed rate
3. Enter the amount to swap
4. Provide your receiving wallet address
5. Send crypto to the generated deposit address
6. Receive swapped coins in your wallet
Lightning swaps add one step: connect a Lightning wallet and pay the invoice. Settlement is near-instant once payment confirms.
No registration. No email. No account creation. Just wallet addresses and a swap.
