Inventa · Europae

The next issue of the Impossible Post opens on 8 October: European inventions, one country to a design, with a larger print run of every design than Vehicula and its own ladder of fusion blocks ready from the first day.

Bison Bonasus for the VI PZKF Congress

A special collection for the VI PZKF Congress in Hajnówka in October: four designs of the European bison, from a single animal to a herd, with the congress postmark, its own envelope and a souvenir sheet.

Mobile Apps in Beta

The iPhone app is in beta on TestFlight and the Android app in beta on Google Play, with the Impossible Post working in full on both. Each release brings the phone closer to the web while we prepare the public store launch.

BindaroID: Verified Collector Identity

A verified identity badge that follows a collector wherever their name appears, granted after review rather than claimed. The badge and the request form are live, and a verified name can be added to the evidence of a registered letter. The remaining work is reach: every place that shows a name should show the verdict too.

Ranking & Collection Analytics

Leaderboards that explain themselves: how complete a collection is, what a league score is made of, and how fresh the data behind it is. The Post Ledger already shows the analytics of every mechanic; floor price trends and volume history come next.

The Impossible Post on Solana

The first issues published outside Polygon. Stamps, envelopes, postmarks and the post office itself on Solana, with the whole postal mechanism rather than a cut-down version: postage paid in Shards, and a second signing key so a Solana wallet can prove itself and open its own mailbox.

One Issue on Three Blockchains

An issue on mathematics and the algorithms behind today's innovations, with the same five designs on Polygon, Solana and Tezos. Each blockchain is an edition of its own, so a full set means collecting a design on all three.

Phygital Postcards

Printed picture postcards, each paired with a token. In the tradition of the maximum card, the matching stamp and the postmark of the day sit on the picture itself, and the token shows both sides of the card.

Shards for Instagram and Facebook

Comments on our Instagram and Facebook posts earn Shards, the way posts on X already do, once you link your account with a code.

Plans Paid Online

Pay for the next month of a plan online, straight from the price list in settings.

Transaction Batching

Approve and list items in a single UserOp via smart account executeBatch for lower costs.

Mobile App (Full Parity)

Public App Store and Google Play release following the beta: native iOS and Android app with complete feature parity, biometric auth, and deep links.

Session Keys (ERC-7715)

Delegated signing for auto-approve patterns, reducing wallet confirmation prompts.

Tezos FA2 Marketplace

On-chain escrow marketplace for Tezos FA2 tokens with smart contract deployment, TzKT event polling, and Beacon wallet integration.
