Your Opaque account

One address for every payment to this account: share it as often as you like. Only its post-quantum key can move what it holds. Send USDC here from any wallet or exchange (Opaque never connects to one); Deposit turns it into private notes, and the first deposit also sets the account up on chain.

Backup file

This browser's account keys and private notes exist only here. A backup holds both, encrypted under this passphrase: without it nobody can open the file, you included.
