Company profile
researched Aug 2026Sturdy is a decentralized finance lending protocol that lets anyone create a liquid money market for any token. Its V2 design uses a two-tier architecture intended to isolate risk between assets while avoiding liquidity fragmentation. The first tier consists of siloed lending pairs, each functioning as a mini money market with a single lending asset and a single collateral asset (for example, lending and borrowing USDC against ETH collateral only). Silos are described as simplistic, immutable and permissionless to create, and technically similar to Fraxlend; a lender exposed to one silo has no exposure to another.
The second tier consists of aggregators built on Yearn V3 lending optimizers, which distribute lender deposits across whitelisted siloed lending pairs to maximize yield. Because lenders choose which whitelisted silos (and therefore which collateral assets) their deposits back, they retain control of collateral exposure while the aggregation layer pools liquidity across silos. Allocation decisions across whitelisted silos are generated by miners on Sturdy's Bittensor subnet, which supplies aggregators with optimized allocations. The protocol positions itself for three user groups: lenders selecting collateral exposure, borrowers using permissionless asset onboarding to borrow against any asset, and project teams seeking to stand up money markets for their tokens quickly.
An earlier iteration of the protocol focused on leveraged yield farming: borrowers posted interest-bearing staked assets, such as Convex LP tokens, as collateral to farm protocols including Convex, Yearn and Lido at up to 10x leverage, with lenders supplying the liquidity for that leverage and earning a share of the borrowers' farming profits.
Business model
Sturdy operates as an on-chain lending protocol rather than a conventional software vendor. Lenders deposit assets into aggregators that route funds into isolated lending pairs; borrowers post collateral and pay interest, and lenders earn yield generated by those positions. Under the earlier V1 model, lenders earned a portion of the profits generated by borrowers' interest-bearing collateral, described as a yield-sharing mechanism.
Traction
Sturdy maintains public documentation, audited contracts, a bug bounty, a DAO with governance and liquidity mining programs, and the $STRDY token.

Market position
Sturdy operates in the isolated/permissionless on-chain lending category, referencing Fraxlend as a technical comparison for its silo design and building its aggregation layer on Yearn V3 optimizers.
Sturdy's stated point of difference is combining isolated risk with shared liquidity: isolated lending markets normally fragment liquidity, whereas Sturdy's aggregation layer pools deposits across whitelisted silos so lenders need not trade off permissionless market creation against depth. Allocation across silos is automated by a dedicated Bittensor subnet rather than set manually.
Technology
The protocol's core is a two-tier smart-contract architecture: immutable, permissionlessly deployable siloed lending pairs (each a single lending asset and single collateral asset, technically similar to Fraxlend) and an aggregation layer built on Yearn V3 lending optimizers that allocate deposits across whitelisted silos. Allocation strategies are produced by miners on Sturdy's own Bittensor subnet and consumed by the aggregators to autonomously optimize yield. The codebase is public on GitHub, and the protocol has undergone third-party security audits and runs a bug bounty program.
Go-to-market
The protocol is accessed through a web application at sturdy.finance, supported by public documentation, a GitHub repository, a governance forum, Discord and Twitter/X channels for community engagement.
Lenders seeking yield who want to control which collateral assets back their deposits; borrowers wanting to borrow against arbitrary assets via permissionless onboarding; and project teams that want to create liquid money markets for their own tokens.
