Best solution for backend BSV hot-wallet

I am looking for a solution to implement a backend hot wallet. It needs to be able to spend pretty much instantly upon API call. The refilling of the wallet can happen manually, but it needs a way to generate a new address and output it somehow so I can refill it. Bonus points if the backend wallet has a way to resolve paymail addresses. Bonus points for links to the respective library. Also helpful to know which proprietary systems exist which could be contacted to see if their system could be leveraged.

Is it possible to use browser's crpyo primitives with bsv library?

I have some code that does a lot of HD derivation and ECIES encryption/decryption and I noticed that it runs quite slow in the browser. I did some profiling and it seems that it spends most of the time in the libraries that handle primitives (sha256 hashing, big int, …).

This makes sense as it seems that we have this primitives natively in node, but we need to use libraries in the browser. I did some Googling and it seems that newer browsers do have some support for this things so I was wondering if it is possible to use that when available? I suspect that would speed up things significantly?

I am thinking about browser’s native APIs such as SubtleCrypto and BigInt. Or even an Emscripten-compiler Javascript library such as js-nacl.

Which cool new possibilities does it enable?

Which exchange should be used?

Of all the exchanges mentioned in Discord, Telegram, Slack and Twitter, none seems to stand out as the obvious choice. All seems to have had their good share of shenanigans, on way or another. Either by delisting, which is an obvious no go, or more dangerous business models like hyperleveraging, crypto loans and worse.
