# Help & FAQs

**Which tokens can I trade?**

Any CRC20 token that has a CRO pair on VVS Finance. 

You can input any ticker that is whitelisted on VVS Finance, or enter the contract address of the token.

If a pair requires a hop, it will still execute. For example, you want to buy xToken, but there is only a xToken <> USDC pair, your transaction will be executed via CRO > USDC > xToken.

**What is a "AA" wallet?**

Our “AA” wallet utilizes Account Abstraction standards such that each wallet has smart contract capabilities. Nexabot has utilized Account Abstraction for the security and convenience of users. Since you have to authenticate with both TG and Google/Apple, there is no single point of failure if one of these accounts becomes compromised..&#x20;

**Why can’t I change my settings?**

This feature is still currently under development. However, your trades will execute at default settings:

Slippage: 0.5% for Buys and Sells

**Why isn’t Nexabot picking up the ticker I inputted to buy?**

Our ticker recognition only picks up tickers that are whitelisted on VVS finance. This is to ensure that you are only buying legitimate tokens, as anyone can deploy tokens with any ticker.

**How much do I pay for transactions?**

We charge 1% on each buy and sell transaction.

**Why is the amount I received different from the minimum received quote?**

Similar to DEXs, we provide minimum received amounts for buy and sell transactions as trades can occur in between the quote and transaction confirming.<br>
