About the CTT Caravela 2023
The CTT Caravela of 28 February 2023 is the first Portuguese crypto stamp and the first StampsDaq postal service application. Theme: Sailing to Discover the Future — connecting Portuguese maritime tradition with blockchain technology.
Technical Premieres
The edition marks four documented firsts in crypto stamp history:
- First Portuguese crypto stamp
- First StampsDaq postal service application
- First solo crypto stamp with 4-tier rarity system
- First travel reward program (trip to Lisbon)
Mintage and Distribution
The edition consists of 40,000 NFTs with dual distribution:
| Component | Quantity | Availability |
|---|---|---|
| Physical stamp + NFT | 30,000 | CTT Online Shop (ctt.pt) |
| Digital-only NFTs | 10,000 | StampsDaq.com |
| Total | 40,000 | — |
The 10,000 digital-only NFTs represent the first explicit phygital separation in crypto stamps — collectors could acquire the edition without a physical stamp.
Rarity System
The Caravela uses a 4-tier rarity system:
| Tier | Mintage | Share |
|---|---|---|
| Common | 35,000 | 87.50% |
| Rare | 4,900 | 12.25% |
| Super Rare | 99 | 0.2475% |
| Unique | 1 | 0.0025% |
The single Unique piece parallels later Austrian premium editions like the Gold Edition Whale Special (27 April 2023, 1 piece with 20g gold bar for WWF).
Collectors activate stamps by entering a 10-digit numerical code on StampsDaq — rarity is revealed only at activation (mystery box mechanic).
Technical Specifications
The CTT Caravela uses a different tech stack than Austrian-centered joint editions:
- Platform: StampsDaq (Estonia — Tallinn, Estonia OÜ)
- Blockchain: Polygon Mainnet
- Smart contract: 0xfa4bf42b9129da1fed0d09916dd2f47a9805f699
- Activation: 10-digit numerical code (not NFC + QR like Variuscard)
- Wallet: MetaMask-compatible via Polygon
CTT Philately Director Raul Moreira positioned the StampsDaq choice as technological innovation, citing CTT's 170-year history of stamp development.
Caravel Motif
The caravel holds central significance in Portuguese maritime history:
- First ship type of the Discoveries era from 1440
- Exceptional maneuverability, including windward sailing
- Suited for coastal exploration and ocean voyaging
- Used until 1488 when Bartolomeu Dias rounded the Cape of Good Hope
- Built at Ribeira das Naus shipyard in Lisbon
- Symbol of Portuguese seafaring tradition
The caravel motif connects Portuguese maritime heritage (Discoveries 1440-1488) with blockchain exploration (2023 onwards).
Travel Benefits Program
StampsDaq launched a Travel Benefits Program with the Caravela, offering collectors a chance to win a trip to Lisbon in September 2023:
| Component | Detail |
|---|---|
| Operator | Viagens El Corte Ingles, S.A. (Lisbon) |
| StampsDaq entity | Stampsdaq Estonia OÜ (Tallinn, VAT EE102529971) |
| Travel period | September 2023 |
| Participation | Caravela NFT purchase via CTT Shop or StampsDaq.com |
This was the first physical reward program connected to a crypto stamp.
Platform Migration 2025
The CTT Caravela 2023 remains the only CTT edition on StampsDaq. In 2025, CTT switched to Variuscard for the CS 6 Poseidon edition, joining the multi-country format:
| Aspect | StampsDaq 2023 | Variuscard 2025 |
|---|---|---|
| Format | Solo edition | Joint edition (5 countries) |
| Collector base | Portugal-focused | Pan-European |
| Platform maturity | Emerging | Established (6+ years) |
| Cross-country synergies | None | Yes (AT, NL, LU, BE, PT) |
The Caravela represents CTT's experimental phase before joining the established joint edition framework.
Historical Significance
The CTT Caravela holds several distinctions:
- First Portuguese crypto stamp — Iberian premiere
- First StampsDaq postal service application — alternative platform test
- First 10,000 NFT digital-only component — phygital separation
- First travel reward program — physical collector engagement
- Predecessor to CS 6 Poseidon — beginning of CTT's crypto stamp program
The edition introduced innovations that either persisted (phygital separation) or remained unique experiments (travel rewards).
Collector Approaches
Four collection strategies:
- Standard collector: Single pack purchase, likely Common variant (87.5% probability)
- Rarity hunter: Multiple packs targeting Rare (12.25%) or Super Rare (0.25%)
- Premium investor: Secondary market acquisition of Super Rare or Unique
- Cross-platform collector: Caravela 2023 (StampsDaq) plus CS 6 Poseidon 2025 (Variuscard) for complete CTT coverage
Frequently Asked Questions
What is the historical significance of the caravel?
The caravel (Portuguese: Caravela) was the first ship of the Portuguese Discoveries era from 1440. It was exceptionally easy to sail, even windward, and ideal for exploring unknown seas — it could follow coastlines, enter river mouths, and stay days on the high seas without supply stops. The caravel was repeatedly used by Portuguese seafarers until Bartolomeu Dias rounded the Cape of Good Hope in 1488. It was structurally central to the Portuguese identity as a seafaring nation.
What makes this edition the first StampsDaq postal service application?
The CTT Caravela is the first documented postal service application of the StampsDaq platform worldwide. StampsDaq, an Estonian tech startup, had specialized in postal service crypto stamps — as a structural alternative to the AT-centered Variuscard joint family. CTT Philately Director Raul Moreira: CTT has maintained an excellent reputation for technological development and artistic innovation throughout its 170 years as official stamp issuer. The second documented StampsDaq postal service application came only 17 months later: Gibraltar Football Mini Sheet (July 2024).
How does the 4-tier rarity system work?
The CTT Caravela uses a 4-tier nominal rarity hierarchy (trading-card-game DNA): Common with 35,000 pieces (87.5%), Rare with 4,900 pieces (12.25%), Super Rare with only 99 pieces (0.2475% — extreme scarcity), and Unique with exactly 1 piece (0.0025% — only one collector worldwide). The mechanic: collector buys pack and enters 10-digit numerical code on StampsDaq — rarity is revealed only at activation (mystery box mechanic). The 99-piece Super Rare is symbolically thoughtful (proximity to the Mythic Rare number of Gibraltar Cryptocurrency edition 2021).
What is the Travel Benefits Program?
With the CTT Caravela, StampsDaq launched a Travel Benefits Program: collectors had the chance to win a trip to Lisbon in September 2023. Trip operator: Viagens El Corte Ingles, S.A. (Lisbon). Stampsdaq entity: Stampsdaq Estonia OÜ (Tallinn). Structurally: first physical collector reward in connection with a crypto stamp worldwide — an innovation that connected collecting beyond digital mechanics with real-world experience. The program thematically fit the caravel (Discoveries / journey) and positioned CTT as an experimental pioneer in the crypto stamp collector engagement scene.
