Keeping your note valid

• A note stays valid only if its exact 5,000-sat carrier moves as the first input and first output. This site always builds it that way.
• Do not use a wallet's own Send button or a marketplace listing for a note. Either can split or merge the carrier, and the note then becomes INVALID for good.
• You need one small plain bitcoin coin (a few thousand sats, no inscriptions) at the same address to pay the fee.
• During the pilot, each signed transfer waits for the issuer to release it, usually within hours. You can cancel until then.
