FixedFloat

What is FixedFloat

FixedFloat is a fully automated cryptocurrency exchange service that has operated since 2018. The platform emphasizes speed and simplicity: users select a currency pair, choose fixed or floating rates, and complete swaps without creating an account. Registration remains optional-required only for order history access. The service is non-custodial, meaning it does not store user deposits; exchanges execute automatically once incoming transactions receive required blockchain confirmations.

The platform supports 68+ cryptocurrencies including Bitcoin (BTC), Monero (XMR), and Bitcoin Lightning Network (LN), alongside Ethereum, Solana, various stablecoins, and altcoins across multiple chain standards. As of 2026-05-30, FixedFloat continues operating after a significant 2024 security incident and subsequent relaunch.

How no-KYC is it?

FixedFloat markets itself as no-KYC and does not mandate identity verification for standard swaps. Users can exchange without registration, email, or personal documentation. However, the platform employs what external monitors classify as "Shotgun KYC"-automated risk screening that may flag transactions as suspicious. When flagged, orders can be suspended and funds frozen pending manual review. This creates a conditional privacy model: most users swap anonymously, but a subset encounters intervention.

The Terms of Service and AML policies reserve broad rights to request additional information, block transactions, and cooperate with authorities. Optional account creation exists for users wanting order history, though this introduces a persistent data trail. The exchange does not appear to collect IP addresses or require VPN disclosure, though standard web logging likely occurs.

Privacy & security

FixedFloat's non-custodial architecture reduces honeypot risk-user funds are not pooled in exchange wallets long-term. However, the platform suffered two security breaches in 2024 totaling approximately $28 million, attributed to repeated exploits by the same attackers. Post-incident, FixedFloat relaunched with a "V2" security overhaul including air-gapped settlement systems, automated scanning, and enhanced two-factor authentication.

The 2024 hacks represent a significant trust deficit. While the service resumed operations and implemented structural improvements, the recurrence of compromise by identical threat actors suggests persistent vulnerability. Users should treat recovery claims cautiously and avoid large exposures. Phishing remains an external risk-copycat domains (e.g., "fixedfloet," "fixedfioat") target FixedFloat users specifically, indicating brand recognition among scammers.

Payments, fees & limits

FixedFloat operates crypto-to-crypto only-no fiat on-ramps or off-ramps exist. Supported payment methods are limited to cryptocurrency deposits across supported networks.

Fee structure is transparent and dual-tier:

• Floating rate: 0.5% service fee, rate finalizes after required confirmations
• Fixed rate: 1% service fee, locks displayed rate for 10 minutes

Additional miner/consolidation fees apply and are embedded in the displayed total. Small-amount swaps may show effective spreads of 10-20% due to network consolidation costs, making the service uneconomical for micro-transactions. Minimum swap amounts start around $1 equivalent.

The platform offers an API for personal and commercial use, with separate terms for affiliate program integration versus standalone commercial access.

User experience & support

The interface supports 12+ languages including English, Spanish, German, French, Portuguese, Russian, Polish, Dutch, Ukrainian, Turkish, Italian, Chinese, Korean, and Japanese. The swap flow is streamlined: select send/receive currencies, choose rate type, input destination address, and deposit to the generated address.

Trustpilot hosts approximately 2,195 reviews, though platform integrity warnings apply. Reddit and Bitcoin Forum threads contain mixed sentiment-some users report successful rapid swaps, others allege frozen funds or unresolved support tickets. The automated nature means no human negotiation; disputes route through ticket systems with variable response times.

API documentation exists for developers, with tiered access for personal use, commercial affiliate use, and commercial non-affiliate use.

Who it's for

FixedFloat suits privacy-focused users needing rapid, small-to-medium crypto-to-crypto conversions without account creation. Bitcoin Lightning Network integration makes it particularly relevant for fast, low-cost BTC transfers. Traders requiring locked rates for brief windows benefit from the fixed-rate option.

It is poorly suited for: large-volume transactions given security history, users needing fiat conversion, those requiring guaranteed non-intervention (due to conditional KYC triggers), or cost-sensitive micro-transaction users affected by consolidation fee scaling.

Alternatives like decentralized exchanges (DEX) or atomic swaps offer stronger non-custodial guarantees, while competing instant exchangers may provide more consistent no-KYC policies without automated flagging systems.
