Swiss Crypto Stamp — Swiss Post Programme

What is the Swiss Crypto Stamp?

Swiss Crypto Stamp (SCS) is the crypto stamp programme of Schweizerische Post AG (Swiss Post), launched on 25 November 2021. With SCS 1.0, Swiss Post was the third European postal operator to issue a crypto stamp — after Österreichische Post (June 2019) and Hrvatska pošta (September 2020).

Five solo editions appeared under this family before the line evolved into the bilateral CHLI joint format with Liechtensteinische Post in May 2025.

Tech Partnership: Inacta + Tokengate

Swiss Post chose a different partner stack from Austria's Variuscard or Croatia's BitX/NodeFactory line:

• Inacta AG (Zug) — backend and blockchain infrastructure, headquartered in Switzerland's Crypto Valley
• Tokengate — marketplace platform built on top of Inacta's stack
• Polygon — chain choice from day one (no Ethereum-to-Polygon migration like AT or HR experienced)

The Crypto Valley anchoring is intentional. Zug has been Switzerland's blockchain hub since 2014, and Swiss Post's choice of Inacta signals that the SCS programme is positioned within the Swiss crypto-economic ecosystem rather than as an isolated philatelic experiment.

The Five Solo Editions

SCS 1.0 — Robot Helvetia (25.11.2021)

The premiere edition uses a Robot Helvetia motif against Swiss mountain landscapes — a deliberate juxtaposition of cutting-edge robotics with iconic Alpine scenery. Five colour variants in the Austrian-style rarity ladder.

SCS 2.0 — Locarno Film Festival (08.08.2022)

Issued for the 75th Locarno Film Festival (Italian-speaking Switzerland's flagship cinema event). Cooperation with the festival makes this the first SCS edition to anchor the programme to a specific Swiss cultural institution.

SCS 3.0 — AI/Midjourney (02.05.2023)

The structurally most important edition: SCS 3.0 is the world's first AI-generated crypto stamp. The motif was created with Midjourney in 14 distinct AI versions, with deeply tiered mintage from 65,000 down to 50 (Rainbow). The edition predates the AT-side AI experiments by months and was widely cited at the time as proof-of-concept that generative AI could enter the official philatelic catalogue.

SCS 4.0 — Marmi the Marmot (24.04.2024)

The fourth edition puts a named mascot at its centre: Marmi the marmot, generated with Midjourney, tours Swiss landscapes across 24 Basic Edition versions of 7,500 pieces each (180,000 in total). Special and Wallpaper editions followed on 25 April 2024, plus a single-piece Unique Edition ("Unicorn").

SCS 5.0 — Swiss-Ski Athletes (04.12.2024)

Issued in cooperation with Swiss-Ski, SCS 5.0 honours 11 Swiss winter-sport athletes, each as its own version. Every version comes in five editions — Basic (10,000 copies), Bronze, Silver, Gold and a single signed Unique copy — for 117,711 NFTs in total.

Evolution into CHLI

Starting May 2025 (CHLI 1.0, 4 June 2025), Swiss Post no longer issues solo crypto stamps. The programme has merged with Liechtensteinische Post into the bilateral CHLI joint family. All later Swiss issues — CHLI 1.0 (Cow + Matterhorn + Vaduz Castle, June 2025) and CHLI 2.0 (Christmas Cow with halving mechanic, November 2025) — sit under that joint family rather than under Swiss Crypto Stamp.

The Swiss Crypto Stamp family is therefore a closed five-edition catalogue covering the 2021-2024 solo era.

Significance

SCS occupies a distinctive niche in the European crypto stamp landscape:

1. Crypto Valley anchoring — first programme to use a Swiss blockchain partner stack
2. AI premiere — SCS 3.0 introduced AI-generated motifs to official philately
3. No platform churn — Polygon from day one, no Ethereum legacy
4. Clean evolution into joint format — the family ended cleanly when the bilateral CHLI line started, no overlap

This makes Swiss Crypto Stamp one of the more architecturally tidy national programmes — a closed solo era followed by a clearly demarcated joint era.
