Receiving Funds
Safebox Web provides one Receive Funds page. Lightning requests receive cash payments. A future Clear method will request transfers of a particular CMU without presenting those credits as cash.
Lightning today
The current method asks the Acorn home mint for a Lightning invoice. Safebox presents the invoice as QR and text, then waits for the user to indicate that the payment has been completed before asking Acorn to finalize it.
The browser does not poll the mint or hold application wallet state.
Clear transfers next
The same page is designed to request a transfer from a particular Clear Mint
Unit. A compatible request will use Cashu NUT-18 with the exact
cmu-<keyset-id> and a strict accepted-mint list.
The transfer remains pending until the received proofs have been validated and refreshed. Lightning cash payments and Clear transfers can share an entry point without implying that they are the same kind of value or transaction.
