Secure On-Chain Data Access Solutions
Herodotus is a powerful data access middleware that provides smart contracts with synchronous access to current and historical on-chain data across Ethereum layers.
Our solutions enable smart contracts to access:
L1 states from L2s
L2 states from both L1s and other L2s
L3/App-Chain states to L2s and L1s

Storage Proofs
Combination of inclusion proofs, which confirm data's presence, and proofs of computation which validate the execution of a multi-step workflow to attest the validity of elements in a large dataset (e.g. Ethereum blockchain or a rollup).
Storage Proof API
Easily integrate storage proofs into your app by utilizing the Storage Proof API.
No need to understand cryptography, zero-knowledge proofs, or how to write circuits.
Turbo
A smart contract interface for the Storage Proof API.
Herodotus Turbo enables trustless interoperability between Ethereum Layers by writing only one line of code!
