Rhinestone lets you sponsor your users’ activity by topping up a single onchain account (“gas tank”). All projects in your organization share one available balance, credit balance, and deposit address. Per-intent sponsorship limits remain project-specific. You manage your sponsorship balance in the Dashboard under Settings → Sponsorship.

​
Viewing your balance

The Sponsorship tab shows the shared available balance, credit balance, and deposit address.

​
Topping up

There are two ways to top up:
  1. Using the deposit modal with a connected wallet
  2. Sending a token transfer manually from any wallet
Only ever send USDC on Base. Any other token will not be credited towards your sponsorship balance.

​
Using the modal

The easiest way to top up is the deposit modal. Press “Deposit”, enter the amount of USDC, and press “Deposit” again.
Approve the transaction in your connected wallet. Once it confirms, your balance updates automatically.

​
Manual deposits

If you’d rather send from an external wallet (e.g. a Safe or mobile wallet), press “Copy” next to the deposit address and transfer USDC on Base to it directly. Once the transfer confirms, your balance updates automatically.
