The Idea
It’s easier to agree on what was useful in the past than what might be useful in the future.
How It Works
Round Design
The funder determines size and eligibility critera for the round.
Project Signup
Projects apply to the round with an impact statement and links to their work.
Project Verification
OSO verifies project data and generates comparable metrics for each applicant.
Voting on Impact
Community members review projects and allocate rewards based on impact.
How It Works
OSO enables comprehensive ecosystem-wide measurement, enabling programs to evaluate impact for new and existing builders in high-growth settings. When paired with incentive programs, retro funding shapes behavior at scale.
Measure impact across an ecosystem
OSO measures every aspect of your ecosystem, from funding to developers to dependencies to user activity. Define impact your way with multi-dimensional metrics.
Incentive-aligned ecosystem growth
Builders win when you win. Drive ecosystem growth by rewarding impact in ways that align with your strategic thesis.
Automate rewards
Setup infrastructure to automatically incentivize thousands of builders at scale, without breaking a sweat on operations.
Leverage human judgement
Accelerate human input at every stage, from eligibility requirements, to reward payouts. Empower your managers to analyze thousands of projects easily.
“World Chain builders are super motivated by the current Retro Funding algorithms.”

Optimism
The Optimism Collective pioneered Retro Funding and has allocated 850M OP from its initial token supply to Retro Funding. Rounds run throughout the year and reward a range of contribution categories, from onchain builders to developer tooling, all powered by OSO metrics.
Filecoin
Inspired by Optimism's early success, the Filecoin ecosystem launched its first FIL RetroPGF round in 2024. The program rewards both technical and non-technical contributions to the success of Filecoin.
