Key Takeaways
- FixedFloat suffered two hacks in 2024 totaling approximately $28 million before shutting down temporarily, rebuilding its security infrastructure, and relaunching. This is a significant trust event for a “no-registration” privacy swap service.
- The fund freezing problem is real and growing — automated AML scanning can trigger KYC holds on transactions. Multiple users report funds frozen for months since late 2025, with unresolved disputes. For larger swaps especially, this is a meaningful risk.
- Fixed rate (1%) locks your exchange rate for 10 minutes from order creation — useful during volatile markets. Floating rate (0.5%) follows live market rates — cheaper but subject to market movements during processing.
- Lightning Network integration is a genuine differentiator — fast BTC swaps via Lightning can settle in seconds, useful for small BTC payments and privacy-focused users.
- US users are explicitly excluded. Estonian FIU license (#FVR001) covers crypto-to-crypto only. No US FinCEN MSB, no FCA registration.
⚡ Bottom Line: FixedFloat is suitable for small, quick crypto swaps where Lightning Network support or privacy matters. The 2024 dual hacks and growing fund-freeze complaints are serious concerns. For amounts above a few hundred dollars, use ChangeNOW or SimpleSwap instead — both have cleaner track records. If using FixedFloat, screenshot your order ID, verify the destination address carefully, and keep amounts small.
⚠️ Risk Disclaimer: FixedFloat was hacked twice in 2024. Fund freezing via automated KYC reported by multiple users. Not available to US users. Use small amounts only. This is not financial advice.
