What is Willow?
Willow is a blockchain indexer that proves its answers. Every query returns the data plus a cryptographic proof you can verify yourself, so you don't have to trust the operator — and the index itself is proven complete and correct against the chain it came from.
How is Willow different from The Graph or Dune?
The Graph is decentralized indexing without integrated proofs — you still have to trust whichever indexer is serving your data. Dune is centralized analytics with no verification layer at all. Willow proves the index itself: every matching event present, nothing dropped, checked against the chain rather than against an operator’s word.
What does "verifiable" actually mean?
Every query returns the data plus a Merkle proof linking it back to a state root committed on-chain. Your client — browser, Lambda, or enclave — checks the math. If anyone tampers with the data anywhere along the path, the proof fails. You do not have to trust the indexer, the database operator, or anyone else in between.
What's a subgrove?
A subgrove is your namespaced scope on the Willow network. You register one, configure what to index or store, and fund it for indexer or storage time. Think of it like a project or schema in a database — except the data lives on a verifiable network and queries come with proofs.
What chains do you support?
Ethereum is fully supported today, with the complete proof pipeline verified on Ethereum mainnet. The circuits are chain-agnostic across EVM chains, so a new chain is configuration rather than new cryptography, and chains get added based on partner demand. If you need a specific chain, tell us.
How much does it cost?
We work with partners directly right now, priced per engagement. and we'll figure out what fits.
Can my data stay private?
Yes. Private subgroves keep your data on your infrastructure and only commit state-root hashes to the public chain. Data is encrypted at rest with XChaCha20-Poly1305, with explicit grant, revoke, and rotate operations for keys you share with collaborators.
Is Willow open source?
The SDKs are open source — TypeScript, Python, Rust, Go, Swift, and React Hooks — along with the on-chain verifier contracts, the Lido proof, and the browser proof verifier, all under github.com/willow-network. The core protocol is currently closed during the managed-service phase; the roadmap moves toward open source as the network decentralizes.
When is mainnet?
Currently on devnet. Mainnet timeline depends on partner readiness, audits, and a few protocol features still in flight. Subscribe to the newsletter or join the Discord for updates.
How do I get started?
Get in touch and we'll get you set up: or email info@willow.tech. If you want a feel for it first, the Dashboard shows live indexed data, every result verified.
