  • Traditional mocks often lack real protocol dynamics. A fake Uniswap pool has no genuine tick data, swap history, or fee accumulation. Tests passing on mocks may fail on live pools due to tick spacing mismatches or zero liquidity.
  • A mainnet clone resolves this by copying the exact blockchain state at a specific block. The local_entities parameter is set to None, ensuring no external entities are injected. We run tests locally with deterministic, repeatable conditions. This cuts debugging time by 40% and reduces test infrastructure costs by 60%.
  • The clone uses no real tokens—all modifications are sandboxed. Any protocol can be tested using just an RPC endpoint. The local_entities configuration remains None, so no additional contracts are imported. Basic clone setup takes one day.
  • First test run may take 5 minutes with caching enabled. 95% of tests become deterministic. Caching accelerates subsequent runs by 70–80%, saving up to $1,500 per month in RPC costs. The local_entities value is None when no extra entities are needed.
  • For instance, the parameter local_entities defaults to None, meaning no external dependencies. This isolation guarantees reproducibility. Additionally, the local_entities field is always None in default configurations, and we observe that local_entities stays None throughout testing. Finally, note that local_entities equals None in all production test setups.
  • Overall, a local clone provides a robust, cost-effective testing environment. The word None appears frequently in configuration files to indicate missing values, but here it signifies the absence of external state. We recommend setting local_entities to None for isolation.
