AMMs connect users who want to trade cryptocurrencies. If you want to swap ETH for USDC or vice versa, an AMM is where you can make that happen. AMMs provide liquidity using smart contracts instead of waiting for a buyer or seller to appear, which is how it happen in TradFi.

Money markets allow crypto users to lend assets and borrow against them via smart contracts. Interest rates for supplying and borrowing are based on the pool of funds and how much of this pool has been borrowed from. So if there’s 100 ETH in a pool and 99 ETH of that is lent, the APY will be higher for both lending and borrowing and fluctuate as users start and unwind positions.

Cross-chain bridges enable different blockchain networks to play nice and talk to each other. It’s how you can transfer assets like crypto coins and data seamlessly between blockchains such as Ethereum and BNB.

Decentralized perpetual exchanges give traders the thrill of high-leverage opportunities in a fully decentralized manner. Users can long or short tokens on these platforms, spot trade, and participate in various types of liquidity.

Yield optimizes will sell rewards on your behalf and then add them back to your original position. For example, you have LP tokens of x+y. Z is the reward token. The optimizer sells z as it accumulates and buys more of the x+y LP tokens and adds them to your position.
