How it works

Four steps. Both cards move together.

  1. 01

    Find the card you want

    Search every verified Collector Crypt card by name, set or grade. Your own cards load from your wallet.

  2. 02

    Lock your offer

    Put one of your cards in escrow. Add USDC if yours is worth less, or ask for USDC if it is worth more.

  3. 03

    They accept, it settles

    Both cards and the USDC change hands in one transaction. All or nothing, nobody in the middle.

  4. 04

    Or cancel for free

    Until it is accepted, pull your card and USDC back any time. After an expiry, anyone can return them to you.

Where the fees go

Every swap fee buys $GRADIX.

A completed swap costs 1 USDC per side. All of it goes to the treasury, and once a day the treasury buys $GRADIX on the market and burns it. Cancelled and expired offers pay nothing.

$GRADIX is not needed to swap. The contract address will appear here the day it launches; any other address is not ours.

Security

Receipts, not promises.

Program on Solana

Written in Pinocchio. 5wvj…JCW6 · Solscan ↗

One escrow per offer

Each offer is its own program address. Cards and USDC never sit in a team wallet.

Verified cards only

Anything outside the Collector Crypt collection (CCry…N2Yf) is rejected.

Three exits only

An escrowed asset can only go back to the bidder, to the owner who delivers the card, or the fixed fee to the treasury.

20 tests, real programs

Run against mainnet Token Metadata, Collector Crypt's rule set and real cards, including 13 attacks that must fail.

Your keys, your signature

The app builds and simulates each transaction; only your wallet signs. Not audited yet: start small.

Before you swap

Questions, answered straight.

What can go wrong, who controls what, and where every fee goes.

Where does the money for the $GRADIX buyback come from?
Only from swap fees: 1 USDC per side on each completed swap. There are no emissions and no outside top-ups. If nobody swaps, nothing is bought. Cancelled and expired offers pay nothing.
Who can change the rules after launch?
An admin key sets the fee, the treasury account and the $GRADIX waiver, and can pause new offers. The program caps the fee at 10 USDC per side, and an open offer keeps the fee it was made with. The admin key cannot move escrowed cards or USDC, and a pause never blocks cancel or accept.
Do I need to claim anything?
No. On accept, both cards and the USDC land in the two wallets in the same transaction. On cancel or expiry, the card, the USDC and the held fee go straight back to the bidder.
What can go wrong?
The program is not audited: a bug could lock or lose escrowed cards or USDC. Card values shown are Collector Crypt’s insured value, an estimate, not a price anyone will pay. An accepted swap is final. Collector Crypt is a third party and could change its collection or transfer rules, which could block new offers. $GRADIX can lose all its value.
Is there a presale, team allocation or airdrop?
No presale, no team allocation, no airdrop. $GRADIX launches on Pump.fun with the standard 1,000,000,000 supply. The dev buy at launch will be disclosed with its transaction.
Is it audited?
No. The program has 20 tests (13 of them attacks that must be refused) run in LiteSVM against the real mainnet Token Metadata and Token Auth Rules programs, Collector Crypt’s rule set and two real Collector Crypt cards. That is testing, not an audit. Start with cards you can afford to have stuck.
Can I swap a card listed on a marketplace?
Not while it is listed. A listing locks the card, so the escrow cannot take it. Delist it first, then make or accept the offer.
What about the Collector Crypt royalty?
The 2% royalty applies to sales. A swap here is two transfers in one transaction, with no sale, so no royalty is charged. Collector Crypt’s transfer rule set still runs on every card move.
How do I skip the 1 USDC fee?
Hold at least 1,000,000 $GRADIX in the wallet that signs. The bidder is checked when the offer is made, the owner when they accept. The waiver turns on once $GRADIX exists; until then every side pays 1 USDC.

Collector Crypt made cards tradable. Gradix makes them swappable.

The card you want is in someone else's wallet.

Offer yours for it. If they say no, cancel and keep your card. Asking costs nothing.
