Assets you can swap

Zerochord swaps stablecoins for stablecoins. The You pay and You receive selectors list the stablecoins registered for the network the deployment reads, and the header names that network.

What the selector offers

Zerochord treats the signed Cardano Token Registry as the allowlist. When any asset on the network has a signed registry entry, the selector offers exactly those assets and the screen says so:

Only the network stablecoins with a signed Cardano Token Registry entry are offered.

When no asset on the network has one, the selector offers every registered stablecoin and the screen states plainly that none of them is verified. That statement comes from the registry itself, not from the network's name.

Each option shows the symbol, its decimal count, and whether it is verified.

Cardano mainnet

All five carry a signed Cardano Token Registry entry, and all five hold six decimals.

Cardano preprod

Preprod USDCx is the real preprod policy, and its decimal count comes from the chain provider's own registry metadata for that network.

Assets whose decimals nobody has declared

Several preprod assets have no decimal count published anywhere: no Cardano Token Registry entry, no mint metadata and no provider metadata.

For those, Zerochord shows every amount in base units and labels them as such. It does not scale them by a guess. A wrong decimal count is a pricing error by a factor of ten, a hundred or a million, so Zerochord prefers a number you can read literally.

ADA

ADA is not offered as something you pay or receive. It appears inside a route as an intermediate step when hopping through an ADA pair produces a better result than going direct.

You still pay the Cardano network fee in ADA from your own wallet. See What a swap costs.

Adding a network

Each network is one configuration file holding its assets, venues and endpoints. See Networks and configuration.
