Paradigm | $80M GitHub & Paradigm PD25 [Closed pre-registration]
Dear community,
We are pleased to announce the next stage of the Github Grants Program — a collaborative initiative with Paradigm created to recognize and support contributors driving forward open-source projects and digital public goods.
Your GitHub account has been pre-qualified for this event. Every form of contribution matters — whether it’s a single improvement or years of consistent engagement — all play a role in shaping the future of open source.
Program highlights:
Funding method: Quadratic Funding — amplifying community impact via a shared pool
Total pool: $80,000,000 USDC
Who can join: Active contributors and maintainers with proven or potential impact — not limited to project founders
Next step:
To confirm your preliminary registration and secure eligibility, please verify your wallet through Paradigm. This step ensures fairness, safeguards against Sybil attacks, and does not require personal information. The process takes less than a minute: simply connect your wallet and sign a verification message.
Important:
A refundable deposit is required for authorization. The full amount will be returned once verification is complete.
➖ Apply Now: grants.paradigm.xyz/apply
Eligibility and funding allocation are finalized only with a valid Paradigm score. Complete instructions are available on the portal.
Best regards,
Paradigm Foundation
In collaboration with GitHub
