One-chain purchasing
How Robincard works
You keep one balance on Robinhood Chain. Robincard handles every cross-chain detail so buying a Solana card feels identical to buying a Robinhood Chain card.
No bridges. No gas tokens.
How one-chain purchasing works
- 01
Fund once on Robinhood Chain
Keep a single balance. It's the only place you ever add funds or approve a payment.
- 02
Choose any card, any network
Browse aggregated inventory from Solana, Ethereum, Base, Arbitrum, Polygon and more.
- 03
Approve one payment
Robincard routes your Robinhood Chain funds to the card's native marketplace behind the scenes.
- 04
Card lands in your Vault
It's delivered to your generated account on its native chain and appears in one unified collection.

Card delivery
You always pay from Robinhood Chain. Cards are delivered to your generated account on their native network. More networks plug in behind the same routing layer.
Custody & security
- Generated accounts use embedded-wallet infrastructure — no raw private keys live in the app database.
- Every transfer requires an explicit user authorization; the backend cannot move your assets on its own.
- A database balance is never treated as proof of on-chain ownership — assets are verified on their native chain.
- Withdrawals require passkey re-authentication and respect per-account transfer limits.
Honest costs
The bridge and liquidity provider stay abstracted — you never see an RPC switch or a gas-token swap. But every cost is disclosed before you approve: card price, source marketplace fee, cross-chain routing, source network execution, estimated slippage, the Robincard fee, and a disclosed safety buffer. Nothing is hidden.
