Ask HN: Good end-to-end testing teams / apps?

We are Web3 company with a good battery of automated tests, but doing end to end testing in Web3 with different wallets, waiting for transactions to confirm is a tough problem to solve.

I am looking for a local or outsourced team that can take on end to end testing, and potentially some exploratory (try and break this) testing.

https://testlio.com/ seems to be the front-runner from some of my research and looking at reviews but would love to support a YC company, or that ethos.

Anyone have any recommendations or building something like this?
