I wouldn't waste your time trying to resolve this issue as the bot is pretty much obsolete - https://dydx.exchange/blog/layer-1-wind-down

Any bot work for layer 2?

[kayden111]

What do you recommend? Go to other platform and build a bot ?

Manually sending contract is not an option because people are using bot that are faster
