The Optimism Collective is redistributing power to humanity through a low-cost, lightning-fast Ethereum-equivalent L2 blockchain.

The OP Stack is the standardized, shared, and open-source development stack powering Optimism Mainnet and the Superchain. It maximizes interoperability and composability between different chains using the OP Stack.

Optimism’s RetroPGF is changing the way impactful software is rewarded. The Optimism Collective funds projects that promote the growth of the Optimism ecosystem. You build projects with impact, you get paid.

⛏️ Hack the Stack

Hackers, bounty hunters, Ethereum scalers: wield the OP Stack for your craziest idea. Use the latest Bedrock release – live now on testnet – and show us what you can do with your own rollup. You can use the full stack for a Superchain-ready L2, or you can go wild with customizing different layers.

We’re most excited about new mad sciences for unreleased EIPs (production-grade account abstraction, EIP-4844 bundling, etc), cross-rollup infrastructure (unified block explorer, oracle rollups, etc), and hacks that power alternative layers layers (alt-data, alt-derivation).

🗯️ Decentralize Our Identities

Identity primitives are the critical infrastructure powering the next wave of DAOs, dapps, and governance. Develop a decentralized identity solution that leverages the AttestationStation v1 contracts. This could include a global passport NFT, a deep fake protection system, or an algorithm for designating Optimism citizenship.

Pro tip: use the Hackathon Starter Kit and AttestationStation SDK for a fast start.
