Basic terms


Tokens are cryptocurrencies that do not have their own blockchain and operate on the basis of another coin's network. For example, Tether USDT, USDC are tokens. 90% of transactions on Calypso Pay occur through tokens like USDT TRC20, USDT ERC20. To make a payment with a token, the wallet balance must have a so-called base currency (Coin) to pay the fee. For example, to transfer USDT TRC20, the wallet must have TRX (Tron) coins on the balance.


Coins are any cryptocurrencies that operate on their own blockchain. Examples include Bitcoin, Ethereum, XRP, Tron, and many others.

Adding a token

By default, users can immediately send tokens to the wallet address. It's important to understand that the address for receiving ETH and receiving USDT (on the same blockchain) will be the same.

To simplify the understanding of this technology, we have added the "add token" button to the interface, allowing users to choose the set of tokens they want to see in the interface.

The process of adding tokens is straightforward. The user clicks the button and selects the tokens they want to see in the interface.

If the user skips the token addition step and directly sends tokens to the address, it will still be automatically reflected in the interface.
