Octant DeFi Hackathon 2025

Use Octant V2 to programmatically allocate a share of realized yield toward any on-chain objective (allocations, incentives, buybacks, rebates, or other mechanisms). Include contracts and a brief policy description for how yield is routed. 2 Prizes, $2000 each Link: [https://docs.v2.octant.build/](https://docs.v2.octant.build/)

Honors the most technically impressive project that advances creation, delivery, or promotion of public goods. Evaluated on mechanism clarity, implementation quality, and viability of adoption. 2 Prizes, $1500 each

Build and showcase the best Uniswap v4 Hook integration that advances the vision of public goods and sustainable DeFi growth within the Octant ecosystem. A user interface is not mandatory, but projects must provide clear evidence of functional code. Hacker Toolkit: https://uniswap.notion.site/octant-defi-hackathon

Best use of Aave’s ERC-4626 ATokenVault to supply/withdraw supported assets and manage yield within Aave v3 as part of the Hack. Document interfaces, accounting, and key safety checks. 1 Prize, $2500 Link: [https://github.com/aave/Aave-Vault](https://github.com/aave/Aave-Vault)

Deploy a new Kalani/Yearn v3-based vault or compose Kalani as a yield source; examples include writing a new Yearn v3 “Tokenized Strategy” or wiring in an Octant V2 strategy that donates some of the yield. Provide configs, deployment addresses, and tests. [https://github.com/yearn/tokenized-strategy-foundry-mix](https://github.com/yearn/tokenized-strategy-foundry-mix) 1 Prize, $2500 Link: [https://kalani.yearn.fi/](https://kalani.yearn.fi/)

Create a clear, runnable guide that explains a technical aspect of Octant V2. Eg. A runnable guide that shows architecture, a minimal integration, technical blog post , or tutorial video. 1 Prize, $1500 Link: [https://docs.v2.octant.build/](https://docs.v2.octant.build/)

Best use of Morpho Vaults V2 that respects the role model and ERC-4626 semantics, with safe adapter wiring and tests. Provide deployments and concise runbooks. 1 Prize, $1500 Link: [https://github.com/morpho-org/vault-v2](https://github.com/morpho-org/vault-v2)

Best use of Spark curated yield Use Spark’s curated yield as part of your hack. Document and explain your integration (repo, deployments, tests); examples include a yield-donating strategy that uses Spark as the yield source. 1 Prize, $1500 Link: [https://docs.spark.fi/](https://docs.spark.fi/)

Rewards the most original mechanism or UX that turns users into ongoing supporters of public goods using Octant V2. Explain the mechanism succinctly. 1 Prize, $1500 Link: [https://docs.v2.octant.build/](https://docs.v2.octant.build/)

Best team from dev3pack Recognizes the strongest end-to-end build from the dev3pack cohort. Judged on execution quality, clarity of architecture, and completeness of delivery. 1 Prize, $1000 Link: [https://dev3pack.xyz/](https://dev3pack.xyz/)
