Where is the Testnet

How can I see progress of submitted transaction when in testnet?

I spend two days integrating the anycall permissionless bridge. base on your docs
Rinkeby anycall address: 0xf8a363Cf116b6B633faEDF66848ED52895CE703b
Ftm test: anycall address: 0x765277EebeCA2e31912C9946eAe1021199B39C61

A sent my first transaction. Im trying to check status so as stated here..BUT the link is dead. In explorer no testnet! How can I see progress of submitted transaction when in testnet?

This link example provided in the docs is dead as well. In fact several api examples provided in the github docs here don't work anymore. Im wondering if the the permissionless bridge is even ready for production ! There are also many confusing concepts, bridge, router, anycall, anyswap, multichainswap etc. I still don't understand whether i need to use your frontend or build my own. I think a clear developer tutorial from start when when have the token contract, to finish at the point when we test a swap, showing how to integrate the our new tokens should be provided, without assuming the we understand the concept.
