Your Card Already Sells Your Spending 🧾

Card networks and issuers have monetised spending data for years, which is why your bank knows where you eat and so does whoever buys that feed.

Crypto was supposed to be the alternative and on $SOL it published the same information to everyone instead of selling it to a few, since every transfer carries a readable amount against an address that never changes.

So a stablecoin card attached to a wallet is a complete record of what you bought, how often and what you had left afterwards, open to anyone who links the address to you once.

Loyalty and rewards make it worse, because the point of a rewards program is to tie purchases to a person, and onchain that tie is permanent.

C-SPL is the piece built for this, a confidential token standard that will seal the amount inside a transfer while the token keeps moving through the same wallets and apps. It has not shipped yet.

The compute layer it runs on has been live on Mainnet Alpha since February 2, where results still settle on Solana as ordinary public transactions, so a merchant can still prove what it received.

Paying with crypto currently means publishing a statement that your bank at least had the decency to sell quietly, and that is the gap Arcium is building to close.
