Swap stablecoins on Cardano. Pay less.

The router checks every venue at once, builds the cheapest path, and shows what you save before you sign.

You pay You receive

One pool is not the whole market.

Cardano stablecoin liquidity sits in many separate pools. One pool alone rarely gives the best price.

The router combines the pools that pay the most. It can split a single swap across several of them, and it can go through a second stablecoin when that pays more.

One pool The routed path

Three steps, one signature.

Your wallet holds your money the whole way through.

STEP 01

Choose the pair

Pick the stablecoin you pay and the one you want.

STEP 02

Read the quote

See the rate, the fees, the slippage and the saving before anything is signed.

STEP 03

Sign once

One signature sends the swap. Nobody else can move your money.

The quote is the promise.

Every quote carries a minimum. That minimum goes into the transaction you sign.

You receive the minimum or more.

The swap settles at the quoted rate, or at a better one. Nothing can fill it below the minimum you signed for.

A bad price cannot reach you quietly. It stops the transaction instead.

Every venue, in one search.

Choose a stablecoin. The router looks for your price at all of these places, in the same second.

The best path is often not the obvious one. The router finds it for the size you are swapping, every time you ask.

How your swap settles.

Cardano venues work in two ways. Your quote always says which one you get.

Direct fill

Done in one step
  • You sign the transaction.
  • It takes the price from the pools itself.
  • The money arrives in the same transaction.

Order fill

Rate locked, timing open
  • You sign an order at a locked rate.
  • The venue completes it at that rate or better.
  • You can cancel while it waits.

No screen here calls an order instant, and every order can be cancelled.

Things it will never do.

These are not promises in a document. They are missing from the code, and the code is open.

  • Pay you rewards, points or referral money.
  • Cover your fee. The wallet that signs is the wallet that pays.
  • Hold your money in an account of ours.
  • Quote you a price it cannot check against a live feed.
  • Hide it when one plain swap beats the route.

Check the saving yourself.

The router keeps a receipt for every swap. The same tool that swaps can rebuild those numbers from the public chain.

Apache 2.0. Every rule on this page is a line you can read.

02

Built from public data

The audit reads the chain alone. It needs nothing from us.

03

The same answer twice

Two runs over the same chain give the same result, down to the last unit.

Any Cardano wallet in your browser. You connect it, and it signs one transaction.

No. Your money stays in your wallet until the swap you signed moves it.

You pay the network fee and the fees of the pools in your route. The router adds nothing on top.

The transaction fails and your money stays where it is. You never fill below the minimum in your quote.

A direct fill lands in the same transaction. An order fill waits for the venue to complete it, and you can cancel it while it waits.

USDM, USDCx, USDA, iUSD and DJED, in any direction.

The quote tells you, and you can take the plain swap instead. The router does not hide a better price than its own.

Your next swap can cost you less.
