One baseball club. One roster. One collectibles marketplace.

A club-owned Cardano marketplace for invited player profiles, baseball image cards, primary sales and resale. Positions are Pitcher, Catcher, First base, Second base, Third base, Shortstop, Left field, Center field, Right field and Designated hitter. Squads are First team, Reserve and Academy.

Cards can show jersey, nationality, season, club, birthplace, height, weight and birth date. Bats supports Left, Right and Switch, using the inherited metadata key preferredFoot. Throws is a separate Left/Right field with the key throws.

Club-approved players, wallet-owned cards

Club platform settings

The club sets its name, crest, banner, sale fee, player royalty and minimum price. Fees go directly to the configured club address; the shop stays closed without it.

An invited roster

The admin adds player payment keys to an on-chain allowlist. Players connect those wallets and mint profiles; the club approves the profiles, not every card or listing. There is no public application form.

CIP-68 and IPFS

Reference tokens at the script hold metadata and the IPFS artwork hash. Fans hold user tokens in their wallets, not in club custody. Cards capture player facts at mint; later profile edits do not rewrite existing cards.

Sale proceeds split on-chain

The marketplace transaction pays seller net proceeds, the club fee and the player royalty at the profile’s payout address. Existing listings keep their fee terms when club settings change.

One-of-one cards, identical copies and edition runs

  • One NFT: a one-of-one card with supply 1, listed by its holder.
  • Several copies: 2–100 identical copies with total supply in metadata. Buyers take one at a time; remaining copies stay at the same price. They are not individually numbered serials.
  • A run: up to 100 identical copies minted to an edition script and sold as club stock. The companion instructions state that run purchases are not listed from My Account.

Pause blocks new listings, new runs and price changes, but already-listed cards can still be bought. Cards held in wallets are not reclaimed; the club cannot restore a lost wallet.

Collectibles, not league rights or enforced benefits

This is not a video archive, live-stat feed, membership pass or ticketing service. Tokens do not enforce seats, votes, visits or discounts. No MLB or other league affiliation or licence is implied. Clubs must hold rights to their crest, kit and player images.

Both uploaded packages in one private download · €10,000

  • baseball_club_nft_platform.zip — unchanged application source, including Aiken validators and the Cardano marketplace.
  • ai-agent-sport-club-nft-platform.zip — unchanged companion building, testing and customization skill.
  • START-HERE.md — setup guidance, source identity and limitations.

The manifest is named app-builder-workspace with no product semantic version. 2026-10-31-bundle is the seller’s release label.

Documentation mismatch: the application uses baseball positions and separate Bats/Throws fields, but the companion customize.md describes its current skin as cricket. Some internal names and fixtures are inherited. Review the source before applying sport-specific examples. Both original ZIPs remain unchanged.

The one-time card purchase uses the existing payment-confirmed private-download flow, separate from Cardano collectible transactions.

Infrastructure, rights and independent review

Provide hosting, database, Cardano network, Blockfrost/IPFS access, club/player wallets, ADA and rights-cleared artwork. Keep credentials server-side, match network settings and test on a suitable test network before public use.

No standalone commercial software licence grant was supplied. Review included and third-party terms. This is downloadable source, not a hosted service. Hosting, implementation, ongoing support, future updates and an AI subscription are not included. Production readiness, live-wallet acceptance and an independent security audit have not been verified.
