📯 Polish Post has announced the return of its Crypto Stamps without revealing the date. ⏳ Impossible Post frames that uncertainty as a sealed prediction contest.

✉️ A participant sends a time capsule to anyone, including themselves, set to open on the predicted return day. Its opening date is recorded on the blockchain and shown on the letter page. 🔏

📜 The formal entry is the letter-page link shared in the games channel with a reason. Up to three capsules may be submitted per participant, each with a different date no later than the end of 2026. Entries close on 9 October or when Polish Post announces the date. The blockchain send time determines eligibility.

🕰️ The prediction is the opening day in Polish time, while the release means the first day of sale stated by Polish Post. The capsule opening closest to that day wins. If predictions name the same day, the earlier-sent capsule takes priority. If no release occurs by the end of 2026, the capsule with the latest date wins.

🎁 Shards go to the three closest predictions, with an extra pool for an exact-day result and a community-voted distinction for the best reasoning. Winners also receive a prize letter franked with the Testudines · Portorium solutum service stamp, which is not sold. 🐢 One Impossible Post stamp is required per capsule, and every opened capsule will be announced. Polish Post does not organize or sponsor the contest.

Shardello! 🇵🇱 The countdown to 11.11 is ON. ✨

108 years since Poland regained independence. Five ways to turn that story into something you can collect.

Meet Mathematica · CVIII · Polonia Restituta, the next Impossible Post collection on Polygon. Autumn landscapes, mathematical discoveries and white, red and gold come together across five original designs. 🧮🍂

Every stamp leads back to 108:

✦ PROGRESSIO connects 1810, 1918 and 2026 in steps of 108.
✦ PENTAGONUM finds it in the 108° angles above Wawel Castle.
✦ GRANIA follows 108 on its Collatz journey above the Tatras.
✦ TRIANGULUM brings Sierpiński’s triangle to the Warsaw skyline.
✦ NOTATIO turns Polish notation into an expression for 108.

🔥 Just 1,080 stamps across the collection. Only 108 are NOTATIO.
💎 Mint prices range from 40 to 200 Shards.
🔍 Watch for misprints: 3% of the supply, across two variants.

And there is a bigger collecting challenge: gather one unused stamp of every design and burn the complete set to forge the publisher’s sheet. Five stamps become one new collectible. 📜

📅 11 November: mint opens for verified Bindaro ID holders.
📅 12 November: public mint opens.

Which design gets the first spot in your collection? 👇

Shardello! 🎨✉️

What happens when Polish art meets mathematics and digital philately?

On 11 November, Impossible Post celebrates Poland’s Independence Day with Artists of Independent Poland: five collectible blocks inspired by five remarkable artists.

🎨 Tadeusz Makowski
🌺 Zofia Stryjeńska
🎭 Witkacy
🚘 Tamara Łempicka
🖌️ Jan Cybis

Each block reimagines an artist in the style of their work and connects their world to a stamp from our Polonia Restituta series.

You can’t buy these blocks directly. Collect the corresponding unused stamps and fuse them to create one.

Only 120 blocks can exist across the five designs, from 36 Makowski to just 12 Cybis.

📅 11 November, 11:11 AM Polish time
