# Tokens

Cryptitan supports **ERC-20** (Ethereum) and **BEP-20** (Binance Smart Chain) tokens, which requires **Ether** and **Binance Coin** respectively to process smart contract transactions. 

Each token was created as a single entity of its own, which implies that miner's fees are charged as the value of the token. However, the administrator is expected to provide the **Ether** or **Binance Coin** required for the processing of all token transactions. 

### Managing Token

After adding the tokens you wish to support in the Control Panel, You need to maintain a sufficient **Ether** or **Binance Coin** on the token's **central wallet** which will be used for the token transactions. It is important you ensure that this address has sufficient balance at all times. Without this, Cryptitan **will encounter errors** while attempting to process token transactions. You will find the **central wallet address** in the Wallet's Control Panel

* Go to **Wallet** tab, under Control Panel.
* Click on the wallet help icon for a token.

{% hint style="danger" %}
**ERC-20** token requires **Ethereum**, while **BEP-20** requires **Binance Coin**  to be sent to the **central wallet address**. Do **NOT** make the mistake of sending the respective coins to the wrong network. The funds will be stuck and irrecoverable.&#x20;
{% endhint %}

### Fee Estimation

Since each token is treated as an entity of its own, the system deducts the miner's fee as the value of the token. It estimates the total **Ether** or **Binance Coin** used for transactions and converts it to the equivalent value of the token.

When a token is received on each users address, it is automatically consolidated into the central wallet. Hence the estimated fee for an external send transaction involves the sum of the consolidation fee plus the external transaction fee, this is deducted from the user's token balance as miner's fee.
