Real-time blockchain event webhooks for your backend
Deliver smart contract events straight to your backend URL as JSON, so you avoid building and hosting your own indexer.
Listen to events on Ethereum, Polygon, Binance Smart Chain and Avalanche C-Chain, with mainnet and testnet endpoints.
Subscribe using a verified contract address or ABI file, or pick from built-in ERC-20, ERC-721 and ERC-1155 event templates.
Choose how many confirmations must pass before a notification is sent, protecting your workflow from blockchain reorganizations.

Open data infrastructure where people own and authorize the data behind AI
People collect data from services they already use through open-source connectors, and that data stays on their own device or encrypted storage they control.
A locally running access engine encrypts data and releases it only against a valid on-chain permission, with every read written to a reviewable access log.
Install @opendatalabs/vana-sdk to request user-approved data, read it from a Personal Server, and settle protocol fees from an app escrow balance.
Groups pool data for privacy-preserving compute jobs, so contributions can be used by AI without exposing raw records.
