Anyware is a cross-chain state verification stack for recent Ethereum state.

At a high level:

1. an offchain client fetches Ethereum proof data and packages it into a proof bundle 2. a destination-chain contract verifies that bundle against Ethereum consensus roots made available through EIP-4788 3. the destination application uses the verified slot value in its own logic

What you ship with

Anyware has two installable pieces:

Offchain TypeScript SDK for assembling proof bundles

Onchain Solidity verifier for checking those bundles

• anyware-prover
• anyware-solidity

Most real integrations need both:

• backend, script, or frontend service layer uses the SDK
• destination-chain contract uses the Solidity verifier

Current tested path

Today, the repo is tested around:

• source chain: Ethereum Sepolia
• destination chain: Base Sepolia

The same architecture applies more broadly to destination chains that expose Ethereum beacon roots through EIP-4788-compatible behavior, but the current demo and test surface is centered on Sepolia to Base Sepolia.

Choose your path

• If you want to generate bundles offchain, start with the SDK quickstart.
• If you want to integrate the verifier into a contract, start with the Solidity quickstart.
• If you want the cryptographic walkthrough, read How It Works.
