Hey team really struggling to get the python sdk working. The snippets are a bit helpful but figuring out the whole async stuff works has been a nightmare, also had some weird issue loading the dylib. If you could just include a fully working code example it would be a lot easier!
--> follow up: this seems to be linked to the fact that USDT contract returned by the resolve_token function (0x3b00ef435fa4fcff5c209a37d1f3dcff37c705ad) has been self-destructed. I guess this is because you're all working off of v2 so testnet v1 is basically deprecated? I couldn't see how to manually load a token in from the code.
