Polybase is web3 replacement for Firebase, Postgres and Supabase with native support for wallet-based permissions, token gating and zk proofs.

Polybase can store any kind of structured data: user data, app state and metadata. Compose it with smart contracts (using oracles) and file storage (like Filecoin) for truly decentralized applications.

Polybase founders Sid Gandhi and Calum Moore got into crypto in 2013 and started Polybase in summer 2022 after seeing too many web3 developers struggle with decentralized storage. After raising their first round of funding, Polybase launched a testnet in November 2022. Mainnet is planned for Q2 2023.
