Goal:

• Connect to the Ethereum network to send block hashes to a specified Starknet smart contract.

Responsibilities:

• Establish a connection to the Ethereum blockchain.
• Call the function to relay the block hashes on Ethereum
• Ensure that transactions are signed and sent with the correct gas estimation.
• Monitor transaction status and confirm successful submissions.

Goal:

• Interact with Starknet smart contracts to perform various read and write operations and verify proofs.

Responsibilities:

• Connect to the Starknet blockchain.
• Execute read operations on specified Starknet smart contracts.
• Execute write operations on specified Starknet smart contracts.
• Verify proofs received from the Ethereum Proof Generator and store them on Starknet.
• Ensure data integrity and confirmation of successful transactions on Starknet.

Goal:

• Generate storage proofs and retrieve block headers from Ethereum, encoding them into RLP format.

Responsibilities:

• Connect to Ethereum nodes to access blockchain data.
• Retrieve block headers for specified blocks.
• Produce storage proofs for given Ethereum accounts and blocks.
• Encode the retrieved block headers and storage proofs into RLP format.
• Return the encoded data to the User Request Manager for further processing.

Goal:

• Manage user requests for specific historical Ethereum account storage values and coordinate interactions with backend components.

Responsibilities:

• Receive and parse user requests for Ethereum account storage values.
• Check if the requested storage value is already available.
• If not available, coordinate with the Ethereum Data Dispatcher to retrieve necessary block hashes.
• Store the retrieved block hashes on Starknet using the Starknet Contract Handler.
• Verify if the requested account has already been proved on Starknet.
• If the account is proved, produce a storage proof using the Ethereum Proof Generator and verify it on Starknet.
• If the account is not proved, generate the account proof first, verify it on Starknet, then produce and verify the storage proof.
• Communicate the final result (storage found or storage not found) back to the user.
• Ensure the storage value is available for use on Starknet once all verifications are complete.
