Sturdy enables anyone to create a liquid money market for any token. Sturdy uses a novel two-tier architecture to isolate risk between assets while avoiding liquidity fragmentation. The base layer consists of risk-isolated pools; aggregation built on top enables lenders to select which collateral assets can be used as collateral for their deposits.

Zellic conducted a security assessment for Sturdy from September 11th to September 13th, 2023. During this engagement, Zellic reviewed Sturdy's code for security vulnerabilities, design issues, and general weaknesses in security posture.
