Onchain flow:

sequenceDiagram
    Note over Client: calldata = encode(func(...args))
    rect rgb(220, 240, 220)
        Note over Client,L1 Contract: view call
        Client ->> L1 Contract: getOperationHandler(calldata)
        L1 Contract -->> Client: revert OperationHandledOnchain(chainId, contract)
    end
    Client ->> L2 Contract: call(calldata)

Offchain flow:

sequenceDiagram
  Note over Client: calldata = encode(func(...args))
  rect rgb(220, 240, 220)
      Note over Client,L1 Contract: view call
      Client ->> L1 Contract: getOperationHandler(calldata)
      L1 Contract -->> Client: revert OperationHandledOffchain(sender, url, data)
  end
  Client ->> Client: EIP-712 signature
  rect rgb(220, 220, 240)
      Note over Client,Gateway: HTTP request
      Client->>Gateway: POST url {sender, data, signature}
      Gateway->>Gateway: Verify EIP-712 signature
      Gateway->>Gateway: Process mutation
      Gateway -->> Client: response
  end

Disclaimer

The implementation still misses some key features that will be added in future PRs:

• the EIP-7528 implementation for paying fees through an ERC-20 token
• the commit/reveal for subdomain registering
• subdomain transferring
