A mint could be anyone, from a single developer or small startup offering a Cashu wallet app, to a national bank holding Bitcoin in reserve and issuing eCash tokens o their clients. The latter is probable, in a hyperbitcoinized future where on-chain Bitcoin transactions are prohibitively expensive for the average user, meaning that opening a self-custodial Lightning channel is similarly cost-prohibitive, and so we implement an eCash workaround that allows users to operate on a Bitcoin standard and stack “eSats”. Mutiny Walley offers this already, so that a new user with no Bitcoin can receive zaps and begin accumulating micropayments, until they’ve earned enough that opening a Lightning channel with those funds is actually rational.
