# Code Audit Preparation Plan
|
|
|
|
The goal is to methodically review each package and replace any stubbed, simulated, or placeholder implementations with production-ready logic. Use this tracker to record progress.
|
|
|
|
## Review Cadence
|
|
1. Select a package or subsystem.
|
|
2. Catalogue all functions/structs that appear mocked, simulated, or simplified.
|
|
3. Link to the source and note what the true production behaviour should be.
|
|
4. Outline remediation steps (implementation, tests, docs, runbooks).
|
|
5. Mark the item complete once merged and verified.
|
|
|
|
## Initial Focus Areas
|
|
- **Arbitrage Execution** (`pkg/arbitrage/executor.go`, `pkg/arbitrage/flash_executor.go`)
|
|
- Simulation-only sections (mock transactions, gas estimation defaults).
|
|
- TODO: Replace with real contract calls, gas oracle integration, and error handling covering on-chain responses.
|
|
- **Detection Engine** (`pkg/arbitrage/detection_engine.go`)
|
|
- Placeholder logging and simplified opportunity scoring.
|
|
- TODO: Reconcile with production heuristics and ensure confidence calculations align with live data.
|
|
- **Metrics Server** (`pkg/metrics/metrics.go`)
|
|
- Confirm metrics cover end-to-end profitability, latency and error scenarios.
|
|
- TODO: Validate against Prometheus/Grafana expectations and add missing labels if required.
|
|
- **Simulation Paths** (`pkg/arbitrage/executor.go` simulation routines, `tools/simulation` vectors)
|
|
- Ensure replay harness mirrors live execution paths and uses realistic inputs.
|
|
- TODO: Gather historical vector captures and remove hard-coded assumptions.
|
|
- **Security/Staging Scripts** (`scripts/run.sh`, deployment scripts)
|
|
- Identify mocked secrets, rate limits, and incomplete hardening steps.
|
|
- TODO: Replace with secure secret management integrations and production checks.
|
|
|
|
## Tracking Table
|
|
| Package / Module | Status | Notes |
|
|
| ---------------- | ------ | ----- |
|
|
| Arbitrage Executor | [ ] | Simulation paths rely on mocked gas estimation, fake receipts, and do not call real flash swap contracts (`simulateFlashSwapArbitrage`, `executeFlashSwapArbitrage`). Replace with production integrations, add on-chain error handling, and move simulation-only helpers under tests/examples. |
|
|
| FlashSwap Executor | [ ] | `submitTransaction`, `waitForConfirmation`, and `createSuccessfulResult` operate entirely on mock transactions/receipts; replace with actual contract bindings, receipt polling, and error handling. |
|
|
| Detection Engine | ☐ | Audit scoring heuristics vs. spec, implement production priorities. |
|
|
| Metrics | ☐ | Validate Prometheus labels and dashboards with SRE team. |
|
|
| Tooling: Simulation | ☐ | Gather live vectors, validate profit calculations, hook into CI. |
|
|
| Scripts: Deployment | ☐ | Harden secrets handling, document rollback plans. |
|
|

Update this plan after each review session and cross link to PRs or issues that close the gaps.
