Most likely it is because of the “OpenMev protection” - this feature protects you against sandwich attacks and also offers some gas rebate. But some times transactions just do not go through. You may switch it off - click on the settings icon (on Sushi UI) and you will see OpenMev at the bottom, toggle it off and try to swap again… For better and timely support, please join Sushiswap Discord - SushiSwap Community
Oh ! Thank you!(^o^)/
But another problems occurred again, I haven’t have enough ETH to pay gas fee😭
I didn’t know the price was so high…
I’m a student, so that I’ll be back when I was become to work in the future!
The transactions on Eth mainnet may be quite expensive, but you could try some side chains like Polygon, Fantom and so on or L2 chains like Arbitrum and Optimism, which are much cheaper… especially the side chains.
We are changing our API to better respond back to end users (you guys) exactly what happened downstream after it gets sent to multiple endpoints, we should have this included in the next week update. This will mean you will have more meaningful responses as to an issue.
Also it appears that for a small number of users that metamask fails to provide a gas price (undefined) and this causes a silent failure, we are fixing this right now. This only seems to affect firefox metamask users we think but we will get a more detailed explanation for you this week.
Please email me at sam@manifoldfinance.com and we will reimburse you, thanks for your patience
that is a scammer , never click such links and always be skeptical. if you have to think to yourself “is this a scam” it probably is a scam! good catch!
