Three instant crypto‑swap services—0trace, FixedFloat and SimpleSwap—operate without requiring users to create accounts or submit identity documents. While each platform offers a no‑KYC experience, they vary in several key areas that can affect a trader’s choice.
Core differences
The services differ most on signed proof of order, Tor accessibility, liquidity model, supported assets and the type of exchange rate offered. None of the platforms mandates an account; order IDs serve as the only credential.
Signed proof of order
0trace provides two PGP‑signed documents per order—a Guarantee issued before payment and a Receipt after payout. These documents can be verified offline using the service’s published PGP key. FixedFloat and SimpleSwap do not issue comparable signed documents.
Tor access
0trace operates a Tor v3 mirror that replicates the full swapping flow, allowing users to complete transactions via the Tor Browser. FixedFloat and SimpleSwap do not state Tor support in their terms.
Rate types
0trace offers only a floating rate, meaning the final amount received may change between the quote and the confirmation of the deposit. FixedFloat and SimpleSwap each provide both fixed and floating rate options, allowing users to lock the amount before sending funds.
Asset coverage
0trace lists over 30 assets across 12 networks, including Bitcoin, Monero, Ethereum, Litecoin, Solana, Tron, Zcash and major stablecoins. SimpleSwap supports more than 2,800 assets from over 20 centralized and decentralized exchanges. FixedFloat’s asset list is not disclosed in the source material.
Liquidity model and data retention
0trace relies on its own liquidity reserves and deletes order data 72 hours after completion, with chat data removed after 24 hours of inactivity. FixedFloat does not disclose its liquidity source. SimpleSwap aggregates liquidity from 20+ providers and retains customer data for up to seven years, with usage data kept for up to three years.
Choosing the right service
- 0trace is suited for users who value verifiable, signed order documents, need Tor access, prefer short‑lived order data and are comfortable with a floating rate and a limited asset list.
- FixedFloat may be preferable for those who require a fixed‑rate option, want a longer operating history, and accept that identity verification could be requested in specific circumstances.
- SimpleSwap is ideal for traders seeking a broad asset selection, the ability to choose between fixed and floating rates, and an aggregator‑based liquidity model.
How to verify details
All three platforms publish their terms of service and related policies. Users should review these documents directly—0trace’s Terms and PGP page, FixedFloat’s Terms updated October 2 2026, and SimpleSwap’s Terms, AML/KYC Policy and Privacy Policy—to confirm current conditions. 0trace also offers an online verifier for its signed order documents.
