IO & Midgard Labs: L2 Scalability Initiative
**Proposal as pdf: [https://ipnso-com.ipns.dweb.link/?cid=QmYfHrmfTKYGK9YR95ewXSwEruEfGPAtpnp1qwoEUekJa7](https://ipnso-com.ipns.dweb.link/?cid=QmYfHrmfTKYGK9YR95ewXSwEruEfGPAtpnp1qwoEUekJa7)** Cardano's current L1 infrastructure — two-hour finality, \~$0.17 per transaction, and \~7–10 TPS, systematically disqualifies it from high-performance verticals such as DeFi, AI agent micropayments, gaming, and consumer payments before a technical evaluation even begins. Upcoming L1 upgrades (Leios, Peras) will strengthen the base layer will not alone meet the requirements of zero-fee or sub-second use cases. Layer 2 infrastructure is the only path to closing this gap in the current cycle. This proposal, led by Input Output in partnership with Midgard Labs, delivers three complementary workstreams: shared L2-agnostic infrastructure (a data availability solution benefiting all current and future Cardano L2s); production hardening of Hydra, including performance optimization, operational tooling, and DeFi reference implementations to support live adopters Delta DeFi and Masumi; and the mainnet launch of Midgard, Cardano's first permissionless optimistic rollup, targeting 10,000+ TPS and sub-$0.01 fees for open-participation applications. Hydra and Midgard are not competing solutions — they address distinct trust models and together cover a far broader range of use cases than either could alone. L2s grow the Cardano ecosystem rather than cannibalize it. Activity on Hydra and Midgard anchors back to L1 through block publication and settlement, generating protocol revenue that would otherwise flow to competing ecosystems. Midgard's architecture additionally includes a mechanism to route a portion of sequencer revenue to the Cardano treasury, creating a durable, non-speculative economic relationship between L2 growth and ecosystem sustainability. By supporting the first wave of production adopters now, this proposal establishes the reference deployments and developer confidence needed to compound ecosystem growth through subsequent cycles.. **Treasury Ask:** ₳10,425,871
