Is FixedFloat safe to connect?
Swap service ยท Instant cross-chain swaps (100+ assets incl. BTC Lightning, XMR, ZEC). Checked 2026-10-24; every line links its source.
Worst case: Coins in flight sit in FixedFloat's hot wallets, which were hacked twice in 2024 and taken offline into maintenance mode; FixedFloat's AML/refund terms could not be verified for this check.
Safe setup in 3 steps
- Swap small amounts and send only when you're ready to complete the order immediately
- Always provide a refund/emergency address you control and save your order ID
- Type ff.io yourself instead of following ads or DMs, and verify any Telegram bot against FixedFloat's own site
