Acurast Hyperdrive

Acurast Hyperdrive is a building block allowing for general bidirectional message passing between Tezos and EVM networks.

It allows smart contracts on a source chain to store ✉️ states that are verifiable on a target chain. It provides a generic way for contracts to communicate between chains by means of validating Merkle proofs about these states stored in the source chain.

How does it work?

As an initial step, a trust anchor service is responsible for transmitting the Merkle root of snapshots between chains. It means that for two chains (A and B), that chain B will know the Merkle root of snapshots contained in chain A, and chain A will also know ones in B.

The Merkle roots transmitted in the step above allow smart contracts in a target chain to validate arbitrary states previously stored in a source chain by calling a validatior smart contract with a proof-of-inclusion for that given state.

It enables interesting use cases for DApps. For example, intracting with a target chain by paying with the source chain token or verifying the onwership of an NFT minted in a different chain.
