Stablecoin Swaps: Up to 98% Cheaper with No KYC

Stablecoin-to-stablecoin swaps on LeoDex now pay just 1 basis point — automatically, on every quote, with no KYC, no account and no token to stake. Here is what we shipped, why we shipped it, and how to use it.

Stablecoins have become the most used product in crypto. They settle in seconds, they cost cents to move, and hundreds of billions of dollars sit in them right now. Most people holding them are not trading — they are getting paid, paying somebody, moving treasury between chains, or parking value outside their local currency.

LeoDex's mission is to make DEX feel like CEX. On stablecoins, one thing was still clearly worse: the fee.

So we shipped Swap Stables. Every stablecoin-to-stablecoin swap on LeoDex now pays 1 basis point — up to 98% off our exchange fee, applied automatically, with no account, no KYC, no token to stake and no tier to unlock.

It is live on LeoDex.io right now.

What we updated

The fee. Stable-to-stable pairs pay 1 bp (0.01%) instead of 35 bps. On a $600,000 USDT to USDC swap, that is $60 instead of $2,100.

Automatic on every quote. No promo code, no page you have to visit. Our backend checks both sides of every quote it prices — normal swap page, shared link or API. If both are verified stablecoins, the lower fee is already in the number you see.

A Swap Stables page. New tab in the top navigation, plus an All / Stables toggle on the swap card. Stables mode filters both token pickers to verified stablecoins, so you are not scrolling past hundreds of assets to find PYUSD on Arbitrum.

A savings display. Every route card shows the old fee struck through, the new fee, and what you saved. That number comes from our API, not the browser — every quote now returns a fee policy declaring what it charged. What you see is what we bill.

A verified stablecoin list. 104 token identifiers, 18 stablecoins, roughly 25 chains — matched on exact contract address, not ticker symbol, so a copycat token can never qualify.

Why we updated it

The cheapest way to convert stablecoins has always been a centralized exchange. Deposit USDT, trade the pair for nearly nothing, withdraw USDC.

That route costs you a passport, a selfie, a proof of address, and a company that can freeze your balance while you argue with a support ticket. You hand over your identity and your custody to save a few basis points.

If you will not or cannot do KYC, onchain was your only option — and it was the expensive one. We do not think privacy should carry a 35 bps surcharge. That gap is now effectively closed.

We believe the future of money is onchain, private, and yours. Not sitting on an exchange that can freeze it, not gated behind a KYC form, and not taxed on the way out. Every release we ship is aimed at making the self-custodial path the obvious one — not the one you settle for.

How to save thousands of dollars swapping stablecoins onchain

Go to leodex.io/swap/stable, or open the normal swap and click the Stables toggle above the amount field. Both get you the same price — the tab is just faster for finding pairs.

Pick your pair, enter an amount, and look at the Exchange Fee line. You will see the old fee struck through next to the new one, with a green 98% off on stablecoin pairs badge underneath.

Then look at the Routes panel on the right, because this is the part we would actually like you to check.

The fee cut is the floor, not the whole story. On a large swap, the route you pick is usually worth more than the fee you saved. In our own testing on a $600,000 USDT to USDC quote, Chainflip's DCA mode — splitting the order into 60 chunks over nine minutes — came out $1,051 ahead of executing it in one shot, because six figures hitting a pool at once moves the price against you.

On another run, NEAR Intents won with Confidential settlement in 52 seconds, for the same output and the same speed as the transparent route. Private execution at no extra cost.

See Every Route. Swap the Best One.

And you do not need to connect a wallet to do any of this. Every Chainflip, NEAR Intents and Relay route supports deposit-address swaps, which means you can swap without ever connecting to LeoDex.io. Generate the deposit address directly from the protocol using our page, scan the QR code from whatever wallet you already use, and your swap goes through.

What's next: buying and selling crypto with fiat

The next major release we are working on is fiat.

Right now LeoDex starts working the moment you already have crypto. That is a real gap. If you are getting paid in dollars, or you want to take profit into your bank account, you still have to route through a centralized exchange — which puts you right back into the KYC and custody problem we just spent this release getting you out of.

So we are building on-ramp and off-ramp directly into LeoDex. Buy crypto with a card or a bank transfer, and sell crypto back to fiat, without an exchange account in the middle.

Two things we care about getting right.

Comparison, not a single provider. The same way we compare swap routes, we intend to compare ramp providers and rank them on what actually lands in your wallet — net crypto delivered, after every fee. Advertised fee percentages are close to meaningless in this industry; a provider advertising 0% routinely pays out worse than one advertising 2%. We will rank on the real number.

Fiat into anything, not just the majors. Ramps only support a short list of assets. LeoDex routes across 60+ chains. Chaining the two means you can buy with fiat and land in an asset no ramp supports directly — which is exactly the kind of problem our router already solves.

We are deep in provider integration work on this now. If there is a fiat corridor or payment method you need, tell us and it will factor into what we prioritize.

In the meantime, Swap Stables is live now at leodex.io/swap/stable. If you move stablecoins regularly — payroll, treasury, rebalancing, or just getting paid in the wrong stable on the wrong chain — try it and tell us what breaks. We read everything.

Supported stablecoins and chains

Swap Stables covers 18 stablecoins across roughly 25 chains, and crosschain pairs qualify — USDT on TRON to USDC on Base gets the same 1 bp as a swap that stays on one chain.
