Do you envision using this for on-chain transactions, or just Lightning? And how would on-chain transactions work given the extended time for confirmations?
Discussion
You’d be able to support on-chain but the challenge will be that you would need to accept the risk that only confirming it’s seen in the mempool is proof of payment. Not ideal but a limitation of using bitcoin for in person payments. Can’t wait around 10 mins to confirm it worked 🤣
Going to look at suggesting sat/vB based on mempool or something.
