One asset does not imply one API model

Trading an ETH product on an exchange and interacting with Ethereum contracts are different execution systems. Preserve that distinction in the architecture and the benchmark. A venue order acknowledgment, an RPC response, and an observed transaction result should not share an unexplained completion label.

Keep state context attached

For onchain research, retain the network, contract identity, relevant block context, and observation timing. A query or simulation is evidence about a particular context, not a reservation of future liquidity. The article links Ethereum’s JSON-RPC documentation for the distinction between calls, submissions, and receipts.

Make authority and uncertainty visible

Separate read-only research from signing. Validate the intended network and operation before approval, coordinate concurrent intentions, and preserve transaction identities across interruptions. Define what evidence permits account state to be reused rather than letting each component invent a different rule.

A useful first experiment

Compare a read-only call, a submitted test transaction, and an observed result using explicitly named timing boundaries. Restart the application between submission and normal completion handling. Require it to locate the existing intention and explain its outcome before creating another action.

Build a connected reading path

Continue with the complete ethereum field guide, which includes a primary reference and practical test scenarios. Use the architecture blueprint for the shared system model and the risk checklist for permission and recovery. Confirm actual product terms with the relevant provider before any implementation.
