Request Supported Currencies and Networks

You can use the API to learn which currencies and payment networks are available.

Request available blockchain networks

Call the available networks endpoint to retrieve list of all supported blockchain networks. Returns an array with network key and display name.

JSON

Code
{
  "data": [
    {
      "key": "ETHEREUM",
      "name": "Ethereum"
    },
    {
      "key": "POLYGON",
      "name": "Polygon"
    },
    {
      "key": "STELLAR",
      "name": "Stellar"
    },
    {
      "key": "BASE",
      "name": "Base"
    }
  ]
}

Request available currencies and networks

Call the available currencies endpoint to receive supported currency definitions. Each entry includes name, key, decimals, network, and provider.

Match the full (key, network, provider) combination when looking up precision. Provider balances have network: null, including stablecoins held off-chain. Network currencies and default fiat definitions have provider: null.

The network definitions depend on the environment. Ledger account responses use uppercase providers such as OPENFX; currency definitions use lowercase values such as openfx. See Currencies for matching rules and how to handle decimal amount strings in balances, transfers, and webhooks.
