Cryptophilately

Crypto stamps, born digital

Impossible Post is a purely digital cinderella philately on-chain. Every stamp is minted, collected, and — unlike a physical stamp — provably scarce and permanent. Cancel a stamp onto a letter to send it, chase the full set, and forge the publisher sheet.

How it works

• MintMint stamps from an open series. A small share are provably-fair misprints (errata), fixed by a committed seed and revealed on a slow drip so no one can snipe them.
• Cancel onto a letterSend a stamp to another wallet as a letter — public or private. Cancel a first-day-eligible stamp and the recipient can claim the prestige envelope (the cover).
• Forge the sheetHold every design in a series and burn them to forge the publisher sheet — the collection's rarest object, and the reason to complete the set.
