Response explained

The response is a JSON file (array of objects) that represents the list of available currencies.

Crypto currencies

The following table explains the fields present in the response with crypto currencies.

Note that the currencyCode, cryptoChain, and name fields are always included in the response payload. Other fields may be omitted if unavailable or not supported by third-party platforms.

Field	Type	Description
`currencyCode`	String	Common ticker symbol (e.g., `BTC`, `ETH`, `USDT`). This is not guaranteed to be standardized and may vary across external providers. The combination of `currencyCode` and `cryptoChain` uniquely identifies a currency in the Sumsub system.
`cryptoChain`	String	Blockchain symbol (e.g., `ETH`, `BTC`, `BNB`, `TON`). For native crypto coins (e.g., `BTC`, `ETH`), this field is present and set to an empty string `""`. ⚠️ Use a symbol, not the full blockchain name (e.g., `ETH`, and not `Ethereum`).
`name`	String	Full name of the currency, if available (e.g., `Ethereum`, `Tether USD`).
`chainId`	String	Blockchain chain identifier, if applicable (used for Ethereum-based chains).
`assetType`	String	CAIP-19 compliant identifier used for internal processing.
`coinmarketcapId`	String	CoinMarketCap asset identifier, also known as Unified Cryptoasset ID (UCID). This identifier is the same across different blockchains for the same token, e.g., `USDT` on Ethereum, Tron, and Solana will all have the same UCID. This ensures consistent identification regardless of the blockchain.
`coingeckoId`	String	Identifier of the currency from CoinGecko (if available).
`chainalysisAsset`	String	Ticker symbol used by Chainalysis to identify the currency. Typically corresponds to `currencyCode`, but in some cases may differ (e.g., wrapped tokens).
`chainalysisNetwork`	String	Name of the blockchain network as defined by Chainalysis. Common values include `Ethereum`, `Binance_Smart_Chain`, `Bitcoin`, etc.
`chainalysisAssetId`	String	Chainalysis internal asset identifier, usually the token contract address for ERC20/BEP20 tokens. This is required for precise mapping in the Chainalysis API.
`ellipticAsset`	String	Ticker or symbol of the asset as used by Elliptic. Matches the ticker field in Elliptic’s asset list.
`ellipticBlockchain`	String	The blockchain name used by Elliptic (e.g., `ethereum`, `bitcoin`, `binance_smart_chain`). It differs from `cryptoChain` that uses ticker symbols like `ETH`, `BTC`, `BNB`.
`merkleBlockchainId`	String	Merkle Science blockchain identifier (if supported).

Fiat currencies

The response with fiat currencies only includes currency codes.

Field	Type	Description
`currencyCode`	String	ISO 4217 currency code (e.g., `USD`, `EUR`, `JPY`, etc.).
