Ethereum Gas Fees Are Sky-High, Here’s Why

Most of the smart contracts that run swaps are relatively cheap, usually using a 150,000 gas limit. There are other more complicated smart contracts that require an even higher gas limit, such as Compound.finance, which often requires transactions with 600,000+ gas limit.

The most active smart contracts, according to ETH Gas Station are Uniswap, and Tether, making up for ~16,000 ETH spent on gas in the past 30 days. Yield-farming is the process of using a variety of DeFi applications such as Uniswap, Curve, Compound, Yam, Maker, Aave, InstaDapp and others to either enter an extremely complicated financial position of loans and collateral, or trade for an instant profit.
