Retro Funding 4: Onchain Builders - round details

Retro Funding 4: Onchain Builders will allocate 10m OP to reward onchain builders who have deployed contracts to the Superchain and driven demand for Optimism blockspace, with impact counted from October 2023 to June 2024. The Foundation says the allocation responds to feedback that Retro Funding 3's 1.5M OP for top applicants was too low, and to growth in developer activity. Eligibility requires contracts on OP Mainnet, Base, Zora, Mode, Fraxtal or Metal with interactions from 420 unique addresses between January 1 and May 1, 2024. Voting will use metrics-based evaluation rather than votes on individual projects, and grants will stream over 100 days via Superfluid after results and KYC approval.
