The rails underneath,and nothing above
Creator fees are paid onchain and exist nowhere else. That is a good reason to build on those rails and a bad reason to make anyone think about them while paying for lunch.
These are the networks the design assumes. None is integrated, and nothing on this site reads from a chain.

Where earnings land
Creator fees settle wherever the coin and the program that paid them live. The holder never chose that, and should not have to care about it.
The design assumes income can arrive from several networks and still add up to one balance.

No network choice at the till
Picking a chain, holding a gas token and timing a bridge are all things a person should never have to do in order to buy a coffee.
Absorbing that is a real engineering problem, and it is one of the larger pieces still to build.

Cross-chain, made simple
Base, Solana, Arbitrum, Robinhood and BNB behave like one connected market. You don’t need to think about networks, bridging, or gas requirements.
One balance
Whatever network income arrived on, the intent is that it ends up in a single balance you can read without translating anything.
There is no balance today, and nothing settles.

Spend from that balance
The end of the loop: the same balance earnings arrive into is the one the card spends from, with no cash-out in between.
There is no card and no spending.

FAQ
Because that is where creator fees are paid. The design treats networks as plumbing: necessary underneath, invisible on top.
No. The networks listed are the ones the design assumes, not ones the product reads from today.
Important: PumpCard does not offer trading, exchange, custody or settlement, holds no crypto-assets, and is not a regulated firm in any jurisdiction. The networks named above are design assumptions, not integrations.
