How vaulting works

1 · Graded and whitelisted

A professional grade and an appraisal fix how many fractions the card is worth, and an admin whitelists the mint at that number. Permissioned on purpose: an open mint would let anyone price their own collateral into an index other people's positions settle against.

2 · You deposit it

The NFT representing custody moves into a program escrow and the vault mints exactly the whitelisted number of fractions — never a number chosen at deposit time. The card is locked for as long as those fractions exist.

3 · The fractions are yours

Hold them, provide liquidity with them, or deposit them into the CLP pool for a share of trading fees. Ordinary tokens with six decimals, priced one to one against a dollar at parity.

4 · Getting the card back

Redemption burns the entire fraction supply and returns the NFT. If you have sold or deposited any of them, you have to buy them all back first. This is the real cost of fractionalising something indivisible.

Quick answers

How can we help?

The essentials about Trade, Earn and Vault.

What am I trading?

One index tracking a fixed basket of graded cards. A long or short position follows the index price; it does not give you ownership of an individual card.

How is the index priced?

Card fractions trade in an on-chain pool. Their price is smoothed over a 30-minute window, then limited by a time-scaled clamp. External card sales are a safety check, not the price source.

What is the risk of a trade?

Perpetual positions use margin. A move against your position can liquidate it and you can lose all of that margin. Check the liquidation price in the ticket before opening.

How does Earn work?

You can deposit kdUSD or eligible card fractions for CLP pool shares. The pool collects fees, takes the other side of trades, and its value can rise or fall with trader results.

What happens when I vault a card?

An eligible graded card is held in the vault and you receive fractions. To redeem the card, you must hold and return the full fraction supply.
