The Market

See what collectors value. Swaps only.

Every Hero Card here was minted from a physical scratch on real packaging, then written to the ALETHRA™ sovereign ledger. Cards move by trade and only by trade — they cannot be bought, sold, or cashed out. ALETHA™ scores the fairness of every swap before it settles.

Assigned by a verifiable random function at mint. ALETHA™ ensures no two cards are identical: every card carries its own scan region, timestamp, and generated story.

How trading is governed

  • 01

    Swaps only, never sales

    Cards trade card-for-card inside a closed ecosystem. They cannot be liquidated for currency of any kind, and no external wallet ever connects.

  • 02

    ALETHA™ scores every trade

    Rarity, sector, and collection history feed a fairness score from 0.00 to 1.00. Even swaps clear; skewed swaps escalate; exploitative swaps are stopped outright.

  • 03

    A parent has the final yes

    Anything ALETHA™ flags goes to the parent dashboard, and the cards stay locked until it is approved.

  • 04

    No keys, no wallets, no gas

    Children see a vault of cards, never a seed phrase or an address. The sovereign ledger settles every transfer at zero cost.

This market ships inside the app.
