i'm going to write about this soon. i believe there is a major solution being developed, that's relatively simple, using lightning, liquid and on-chain.

it will make custody much easier while automating things... allowing any organization to run btcpay server even without a lightning node.

Some of the issues are unsolvable because of the current on-chain dynamics. but gl to us, I hope so too.
