This paper presents a preliminary exploration of the design and deployment of solidiary primitives for Web3 social security, based on insights generated during Other Internet's Web3 Work Forum held in July 2023. The paper proposes a modular framework to develop solidarity primitives addressing the three dimensions of security for DAO contributors: psychosocial stability, financial stability, and regulatory clarity. Additionally, it outlines a range of on-chain and off-chain mechanisms and improvement proposals specific to each dimension. Lastly, it discusses current challenges to implementation.
