The site has a problem and the transaction costs are very high. This is the problem of all of us 😑 🤕 ---

Yes, there is a _heavy traffic_. But also, it’s a good kind of **stress-test** for Linea network. ---

but as it based on uniswap, shouldn’t this be at the backend of uniswap? I think there is defect in smart contract w/ v3 pools ---

For example: When you try to exchange 0.000005 ETH, you fail try to refresh the page and enter an amount less than 0.00001 ETH, you can make as many exchanges as you like, but the most important thing is to enter a small amount for a successful transaction. Please also increase the slippage and choose Full Range If this solution does not work, please avoid trying to swap for now. ---

I guess it’s just because of network overload, the smart contract plays a less important role here. The network needs more validators, maybe. For now, even **speed up** doesn’t work to proceed a transaction. I got about 10 pending txs. ---
