Launch

One card, one
coin

Launch your coin on pump.fun and write the card's certificate on Solana, from one page.

Mainnet. Real SOL. Two wallet approvals: the launch, then the card note.

What a launch creates

CoinA pump.fun token with your name, ticker, image and dev buy
Card noteGrader, certificate, card and coin written in a Solana memo, permanent and public
CostSolana fees, pump.fun’s fees and your dev buy. cardr takes nothing
LimitThe note is a public claim. It does not stop someone else noting the same certificate, and it is not custody of the card

Memecoins can go to zero. Anything you launch or buy is at your own risk, and the card is not collateral.
