Currencies Overview

Currency identifiers are assigned internally by CoinPayments to each coin and token that the system supports.

currencyId fields are used commonly throughout the CoinPayments API.

Relevant /currencies endpoints have been exposed to alow merchants to view the list of available cryptocurrencies within the system and evaluate their capabilities.

To enable interfacing with multiple tokens on the same blockchain, each token id will be the base coin id combined with the smart contract address.

For tokens, the currency id format is as follows: {coinId}:{smartContractAddress}

i.e. for ERC20 USDT on the Ethereum chain (id 4), the currency id would return 4:0xdac17f958d2ee523a2206206994597c13d831ec7
