What is WeaveDB?

WeaveDB is a NoSQL database powered by Warp Contracts (SmartWeave) on the Arweave blockchain.

The query APIs are similar to Firestore from Google but completely decentralized.

  • Data is stored on the Arweave permanent storage where anyone can access without permission.
  • User authentication is done by pure cryptography using crypto wallets such as MetaMask and ArConnect.
  • SmartWeave makes it possible to apply complex computation to stored data for web-centric large-scale dapps just like web2 apps.

Crypto Account Authentication

Database access is permissionless and authentication is done with pure cryptography, which authorizes EVM-based accounts with EIP-712 signatures on SmartWeave contracts.

Other types of crypto accounts will be supported in the future such as Arweave and Polkadot.
