Final Release Summary – 2024-10-05
Execution Overview
- Scripted checks:
./scripts/run_profit_simulation.sh - Unit tests:
GOCACHE=$(pwd)/.gocache go test ./... - Integration tests:
GOCACHE=$(pwd)/.gocache go test -tags=integration ./... - Container build:
docker build -t mev-bot:local .
Test & Build Results
| Check | Status | Notes |
|---|---|---|
| Unit test suite | ✅ Passed | All packages compiled and unit tests succeeded with cached Go 1.25 toolchain. |
Integration tests (-tags=integration) |
❌ Failed | Multiple suites require live RPC/endpoints and outdated helpers. Key blockers: missing bindings/arbitrage import path, deprecated config fields in test/arbitrage_fork_test.go, reliance on real Arbitrum RPC (DNS failures in sandbox), parser validations expecting fields not supplied by fixtures. |
| Docker build | ⚠️ Blocked | docker build denied (open /run/user/1000/libpod/tmp/alive.lck: permission denied) inside sandbox runtime. Requires elevated container privileges on build host. |
| Profitability simulation | ✅ Passed | Default vector run succeeded; net profit 0.087300 ETH, profit factor 6.37. Reports in reports/simulation/latest/. |
Secrets & Keystore Readiness
- Added smoke-test environment at
env/smoke.envwith compliantMEV_BOT_ENCRYPTION_KEY, keystore/audit/backup paths, and metrics defaults. Production.envtemplates now setMEV_BOT_KEYSTORE_PATH/audit/backup defaults soscripts/run.shscaffolds required directories. - Created placeholder directories
keystore/smoke,backups/smoke,logs/to satisfy key manager validation. Application will auto-generate a trading key on first start using this profile. - Action: Swap RPC placeholders in
env/smoke.envbefore hitting live infrastructure and load actual production secrets via preferred manager (Vault/SSM/etc.).
Monitoring & Alerting
- Published Prometheus alert rules in
monitoring/alerts.yml:MEVBotHighErrorRate– fires ifmev_bot_trade_error_rate > 0.25for 10m.MEVBotDegradedProfitFactor– fires ifmev_bot_profit_factor < 1for 15m.
- Updated metrics collector to expose
mev_bot_profit_factorin JSON and Prometheus endpoints. - Deployment guide (
docs/6_operations/DEPLOYMENT_GUIDE.md) now referencesenv/smoke.envand documents alert wiring.
Observations & Follow-ups
- Integration harness needs refactor to match current API signatures (
arbitrage.NewArbitrageService, config structs, parser fixtures). - Network-bound tests require controllable RPC stubs or local fixtures to run in CI (legacy suites now gated behind the
legacy/forkedbuild tags). - Container build requires host permissions or buildkit alternatives; publish Drone/Harness artifacts for verification when permissions are available.
- Secrets management decision outstanding (Vault vs. SSM vs. local
.env).
