Hydranode.net Its custodial but ofc you withdraw sats to your own wallets asap. We have many businesses accepting, each operates a bit differently. If its real world business, employees need to be minimally trained. Just open terminal on phone or tablet, fill amount and thats it. Can be added as excommerce plugin for Woocommerce.

Clients who want fiat can go walk. Bitcoin only :)

We allow export of csv with all transactions and their exact fiat values so business can use that for taxes as if it was cash. They bare exchange risk as they wish.
