Opentip is an open-source tip jar on Base. Send crypto to the developers who build the tools you use.

How it works

Browse registered repositories or visit any repo page directly. Search by name or owner.

Connect your wallet, check the AI-generated summary on the About tab, choose USDC, ETH, or OAR, enter an amount, and send. Minimum tip is $1.

95% of every tip goes directly to the developer. They connect their payout wallet and claim anytime.
