Maintainers claim on their schedule.

The balance belongs to the maintainer the moment a tip lands. They withdraw whenever they choose.

Built for trust

Non-custodial by design.

Tips never sit in an Opentip account. Only the registered payout wallet can withdraw a maintainer’s balance.

FAQ

Do I need an account to tip a repo?

No. Connect a wallet, choose ETH or USDC, and confirm. Tipping does not require an Opentip account.

If I send ETH, does the maintainer receive ETH?

Yes. A contribution stays in the token you send. ETH is claimable as ETH, and USDC as USDC.

What chain does this run on?

Base. Contributions, claims, and fees are on the public record.

Can anyone claim any repo’s tips?

No. Claiming requires the payout wallet registered for that repo. Registration happens after a maintainer signs in with GitHub and Opentip verifies ownership or maintainer access.

Has the contract been audited?

The contract is public and verifiable. Read the source and the on-chain record before you send a tip.

What happens if a repo changes owner?

The payout address does not follow GitHub on its own. The registered wallet can update it, and Opentip can reassign it after the new maintainer verifies access.

Isn’t the contract centralized?

An owner key can pause tipping, registrations, payout-address updates, and claims; set the fee to any rate up to a hard 10% cap; and reassign a payout address. It cannot withdraw a maintainer’s pending balance — only the current payout address can claim it. The owner can withdraw the separate fee balance. Those actions are public.
