Mint Attestations offer a new way to make your Gitcoin Grants donations visible and lasting, turning each contribution into a personalized, onchain proof of support. These attestations not only celebrate your impact but also connect you with the projects you back, offering opportunities for future rewards and deeper engagement. Whether you’re supporting bold innovations or grassroots initiatives, Mint Attestations transform your generosity into a shareable story that inspires others to get involved.
It’s GG22, and you’ve just made a donation to a project you truly believe in. Maybe it’s an open-source tool you know will change the game, or a community initiative that’s making a real world difference. Now, instead of your support disappearing into the ether, you can mint an attestation—creating a permanent, onchain record of your contribution.
Each attestation is a verifiable, shareable proof of your contribution—something you can share, revisit, and even use to unlock future rewards or recognition from the projects you support. Whether you’re backing new ideas or helping communities grow, your attestation becomes part of the project’s story, signaling your early support and encouraging others to get involved.
By minting your attestation, you create a lasting connection between you and the causes you care about—one that’s easy to share and impossible to forget.
"We're really excited to enable GG22 donors to mint attestations of their contributions onchain. In previous rounds, we saw donors create their own social posts to share their donations—we wanted to make this easy and fun for them. The attestations also allow projects to identify their early supporters and involve them in future activities."
— Kat Young, Head of Product
Mint Attestations are a new way to immortalize your Gitcoin Grants donations on the blockchain. Think of them as digital stamps of support—blockchain-verified, personalized, and designed to celebrate the projects, communities and causes you care about. When you make a donation, you can mint an attestation that symbolizes your contribution and receive a unique image that you can share with your network.
The process is quick and seamless:
This seamless experience is integrated into the Gitcoin platform and currently recorded on Arbitrum, ensuring smooth access and visibility.
We created Mint Attestations to meet the needs of both builders and donors, enhancing their experience and recognizing their contributions in meaningful ways.
As Aditya, put it: “It's super exciting that we've finally built in the ability for users to share their contributions across other protocols and products. The data isn’t limited to Gitcoin anymore, which is a big step forward.”
Your attestation isn’t just a thank-you—it’s proof of your support, recorded onchain and ready to share. It marks your contribution as part of a project’s story, creating a visible connection between you and the causes you believe in. Over time, these attestations become a personal record of your impact, showing the journey of the projects you’ve helped grow. Sharing them can inspire others to follow your lead, sparking new donations and building momentum for the community.
Mint Attestations turn your donation into something bigger—a connection to the projects you believe in and an invitation for others to join you.
