# Chains & tokens

> Web3 chains and crypto checkout tokens.

Crypto catalog for checkout, quotes, and swaps. **Live** merchants use mainnet chains; **Test** merchants use testnet chains. Fiat checkout methods are listed separately on [Countries & fiat](/reference/countries-and-fiat).

Public API:

* `GET /api/public/catalog/chains`
* `GET /api/public/catalog/tokens` optional `?chain_id=`

## Live chains

Use with `?environment=LIVE` or the default catalog response.

## Offchain rails

Internal sentinel chains for fiat quote routing: BANK chain ID 2, MOMO chain ID 0. These are not crypto checkout tokens.
