# Trading

Trading on decentralized finance (DeFi) operates differently compared to centralized exchanges (CEXs). On DeFi, trades are executed directly on the blockchain, leveraging Coinrule’s integration with a liquidity **aggregator** ([Li.Fi](https://li.fi/)) and **Paymaster** for efficient execution without the need for a gas token (ETH) balance in your smart account.

When creating trading rules on Coinrule, you have the ability to set two additional parameters specific to DeFi: '**Max Gas Price'** and '**Max Slippage'**. These fields allow you to define the maximum transaction fees you are willing to pay and the acceptable price deviation during execution, for better control over your trades in the more volatile DeFi environment.

Due to the permissionless nature of blockchains and the vast number of cryptocurrencies available, Coinrule has restricted trading to a **curated list** of whitelisted tokens. This measure is in place to protect users from trading unofficial or potentially malicious tokens, safeguarding your experience on the platform. While we aim to expand the scope of tradable tokens in the future, this limitation currently ensures a secure environment, particularly when using features like the "**Any Coin**".
