# How it Works

## Smart Contract Exchange

The Base3D smart contract controls all the B3D token trading. This is called a smart contract exchange. This revolutionary blockchain technology secures liquidity in the smart contract, no need for liquidity LP tokens. Base3D is 100% fully decentralized. You don't even need the website to interact with the contract. You can use BaseScan directly if you had to. Your ETH is secured in the smart contract and can only be accessed by your wallet. The contract creator can't modify or change anything on the smart contract it's locked forever.
