Sturdy Finance

Sturdy is a decentralized finance (DeFi) lending protocol that enables permissionless creation of liquid money markets for any token. It introduces a novel two-tier architecture combining isolated lending pairs with a shared liquidity aggregation layer. This design allows users to lend and borrow assets with isolated risk exposure while benefiting from deep liquidity and AI-optimized yield strategies. The protocol’s backend leverages Sturdy’s Bittensor subnet, which uses machine learning miners to autonomously optimize fund allocations across lending silos, maximizing returns for lenders.

At the base layer, Sturdy operates siloed lending pairs, each representing a mini-market with a single lending asset and a single collateral asset. These silos are isolated, meaning lenders in one silo have no exposure to others, enabling precise risk management. On top of this, the aggregation layer pools liquidity from multiple silos and distributes it automatically based on yield optimization algorithms. Lenders can select which collateral types they want exposure to, maintaining control over their risk profile while accessing aggregated liquidity.

Sturdy targets DeFi developers, financial institutions, and token projects seeking to launch liquid money markets quickly and permissionlessly. Its architecture addresses common challenges in isolated lending protocols, such as liquidity fragmentation and limited yield optimization. Users can get started by interacting with Sturdy’s Yearn V3-based lending optimizers through the web app or integrating via open-source smart contracts.
