# Zerochord (/users)



Zerochord searches every trading venue it can reach for the cheapest way to turn one
Cardano stablecoin into another. It shows you the result as a quote, and it writes the
important number from that quote into the transaction you sign.

You keep your funds the whole time. Zerochord never holds them.

## What you get on every swap [#what-you-get-on-every-swap]

**One quote, and the transaction is held to it.** The quote carries a minimum output.
That minimum goes on chain. If the market moves so far that the swap can no longer
deliver it, the swap fails instead of filling at a worse rate.

**The comparison, in the open.** Every quote is measured against the best single pool
that trades the pair directly. When routing beats that pool, the panel shows the saving.
When it does not, the panel says so and offers to quote the direct pool instead.

**One signature.** You approve one transaction in your wallet. The wallet that signs is
the wallet that pays the network fee.
