No single no-KYC exchange fits every swap. <a href="https://0trace.io/?utm_source=blockonomi&amp;utm_medium=pr&amp;utm_campaign=nov26" rel="noopener noreferrer nofollow">0trace</a>, FixedFloat (ff.io) and SimpleSwap are instant exchanges where an account is optional or absent. They differ on proof of order, Tor access, liquidity, asset coverage and rate types. 0trace leads on some and trails on others: it offers only a floating rate, lists far fewer assets than SimpleSwap and launched in March 2026. Competitor facts come from each service’s own terms, checked on October 22, 2026. Pricing is left out because it changes often; read the quote before you send anything.

The three differ most on signed proof, Tor access, liquidity, asset coverage and rate types; none requires an account.
Competitor cells paraphrase each service’s own documents as read on October 22, 2026: FixedFloat’s Terms of Service (updated October 2, 2026), SimpleSwap’s Terms of Service (in force from September 7, 2026), its AML/KYC Policy (October 30, 2025) and its Privacy Policy (July 10, 2026). 0trace cells follow its Terms and site pages. “Not stated” means the pages we read are silent, not that the answer is no.

<h2 id="a-rel-noopener-noreferrer-nofollow-a-what-does-0trace-s-signed-proof-add-to-the-comparison"><a rel="noopener noreferrer nofollow"></a>What Does 0trace’s Signed Proof Add to the Comparison?</h2>
It adds two PGP clear-signed documents per order that anyone can check offline, without contacting 0trace.
<img src="https://blockonomi.com/wp-content/uploads/2026/11/21.png" alt="" width="1200" height="457">
0trace issues the Guarantee when the order is created, before any deposit, and the Receipt after the payout. Both carry a signature from 0trace’s published PGP key, fingerprint C8A0 3EAF 6531 C975 561F 9FDA 1B80 0B98 D27C 5611 (published at 0trace.io/pgp).
Per its Terms §11, 0trace stands by the contents of a document whose signature is valid. Neither FixedFloat nor SimpleSwap issued any signed per-order document in our unpaid orders, and we found none described on their pages. In our unpaid orders on October 22, 2026, both FixedFloat and SimpleSwap showed a deposit address without requiring an email or ID, the same as 0trace; the difference appeared only in what each service issued afterwards.
A valid signature shows that the document came from 0trace’s key and has not been edited. It does not make the blockchain private: transfers stay public on-chain. The site’s verifier runs in the browser and uploads nothing. Before you pay, compare the deposit address in the Guarantee with the one on the order page.
<h2 id="a-rel-noopener-noreferrer-nofollow-a-what-does-a-floating-rate-change-compared-with-a-fixed-rate"><a rel="noopener noreferrer nofollow"></a>What Does a Floating Rate Change Compared With a Fixed Rate?</h2>
A floating rate is a quote that keeps tracking the market until your deposit confirms, so the amount you receive can differ from the amount first shown.
On 0trace, the Receive field shows the amount after the service fee and the network fee. 0trace calculates the final amount from the rate in force when the deposit reaches the required number of confirmations. That number depends on the network, not on the amount you send, and the confirmations page lists it for each network. The order page shows the count as it grows. The longer the wait, the more time the quote has to move. The fee rate recorded when the order is created does not change afterward, even if 0trace adjusts the fee for later orders.
FixedFloat and SimpleSwap both offer a fixed option next to a floating one, per their terms. If a locked amount matters more to you than any other row in the table, 0trace is not the right pick.
<h2 id="a-rel-noopener-noreferrer-nofollow-a-how-do-track-record-and-asset-coverage-compare"><a rel="noopener noreferrer nofollow"></a>How Do Track Record and Asset Coverage Compare?</h2>
0trace launched in March 2026, so its track record is short, and it lists far fewer assets than SimpleSwap.
0trace’s list covers Bitcoin, Monero on a native node (on-chain, not wrapped), Ethereum, Litecoin, Solana, Tron, Zcash and the main stablecoins such as USDT and USDC. Payouts are not open for every asset yet: coins on Base, Polygon and Avalanche, plus ETH on Tron, are send-only, and the networks page shows the live status.
FixedFloat’s history includes two reported incidents. The Block reported a February 2024 exploit that FixedFloat confirmed, and ForkLog reported a second in April 2024. Both are past events and say nothing about its current setup.

Choose by the constraint that matters most: proof and Tor access point to 0trace, a locked rate to FixedFloat or SimpleSwap, and a rare coin to SimpleSwap.
If you are searching for a FixedFloat alternative or a SimpleSwap alternative, check each option below against the pair you want to swap.
<h3 id="a-rel-noopener-noreferrer-nofollow-a-choose-0trace-if"><a rel="noopener noreferrer nofollow"></a>Choose 0trace If…</h3>
Choose 0trace if you want a verifiable record of the order and can live with a floating rate and a shorter asset list than SimpleSwap’s.
<ul>
 <li>You want signed documents you can check offline before and after the swap.</li>
 <li>You use Tor Browser and need the whole order flow to work there. Per Terms §10, the onion mirror serves the same application as the clearnet site.</li>
 <li>You want short-lived order data and a site with no third-party scripts, and you accept that 0trace holds the deposit while the swap runs.</li>
 <li>Your swap ends in Zcash and you want the payout to land in a shielded address. 0trace pays out to u1 and zs1 addresses directly from its own Zcash wallet.</li>
 <li>You want the interface in your own language. The site is available in English, Russian, Spanish, German, Turkish and Traditional Chinese.</li>
 <li>Your pair is on its list. It is a young project, so read its Terms and PGP page first.</li>
</ul>
<h3 id="a-rel-noopener-noreferrer-nofollow-a-choose-fixedfloat-if"><a rel="noopener noreferrer nofollow"></a>Choose FixedFloat If…</h3>
Choose FixedFloat if you need a fixed-rate option and accept terms that allow identity checks in the cases its §6.5 and §7.9 describe.
<img src="https://blockonomi.com/wp-content/uploads/2026/11/22-1.png" alt="" width="1220" height="460">
<ul>
 <li>You want to lock the amount before you send. 0trace cannot do that.</li>
 <li>You value a longer operating record, and you have read the incident reports above next to its current terms.</li>
</ul>
Check the freeze clause in the table before you send. FixedFloat does not state its liquidity model, so that part stays unknown.
<h3 id="a-rel-noopener-noreferrer-nofollow-a-choose-simpleswap-if"><a rel="noopener noreferrer nofollow"></a>Choose SimpleSwap If…</h3>
Choose SimpleSwap if the asset you need is not on a short list, or if you want a fixed or floating rate from an aggregator.
<img src="https://blockonomi.com/wp-content/uploads/2026/11/23-1.png" alt="" width="1164" height="602">
<ul>
 <li>Your coin is not on 0trace’s list. SimpleSwap’s catalog is far wider.</li>
 <li>You want a price sourced from 20+ liquidity providers by design.</li>
 <li>You want either rate type, and an optional account suits you.</li>
</ul>

Read each service’s own terms and run 0trace’s verifier, because policies change without notice and this comparison reflects October 22, 2026.
Start with the clauses cited in the table, and for 0trace also read its Terms and its PGP page at 0trace.io/pgp. The official site is 0trace.io only; it is not affiliated with 0-trace.cc.
