yes! this would be an amazing use case. that truly fulfills the vision of bitcoin. bitcoin was designed as peer-to-peer electronic cash system. just that bitcoin is not cash, because bitcoin is not stable and it lacks privacy. cash is stable and private.
we already have usdt, usdc, dai, pax, and busd on incognito. so pUSDT, pDAI, and pUSDC are actually crypto cash. they are stable. and they are private. you can already send these stablecoins privately already via the wallet. for example, crypto payroll is something that you can already do with the current wallet.
do you have a contact at flexa? would love to talk to them.
last i checked, they have like 40,000 retail locations. so it would be amazing to allow people to spend crypto cash at those locations!
