on Arbitrum, 80% of reverted swaps concentrate in USDC/WETH pairs and cluster at block tops, signalling a sustained latency race outside priority-fee auctions. +- **Optimistic MEV measurement (Jun 2025):** Quantifies "on-chain probe" strategies driving 7% of Arbitrum gas usage in Q1 2025 despite limited fee contribution—highlighting speculative load on sequencers and sensitivity to volatility and aggregator activity. +- **Cross-chain arbitrage taxonomy (Jan 2025):** Longitudinal study across nine chains attributes ~32% of observed events to bridge-based moves, yielding a conservative $9.5M profit lower bound; provides a baseline for assessing Arbitrum cross-domain MEV defences. +- **Sequencer profit sustainability (Mar 2025):** DAO-commissioned report decomposes sequencer revenues/costs (including blob and L1 settlement fees) and stresses integrating Timeboost and orderflow auctions into long-term economic planning. +- **Community proposals and dashboards (Apr–Sep 2025):** FairFlow proposal aims to adjust Timeboost parameters for broader participation; community analytics suggest Timeboost revenue is nearing parity with base fees (~$1M/month) with potential to reach $100M annually if adoption expands. + +*Actionable follow-up*: Integrate insights above into experiment backlog—e.g., replicate Timeboost revert analysis locally, extend spam-detection metrics in `pkg/scanner`, and simulate bridge-based arbitrage using the cross-chain taxonomy as benchmarks. + +## Data Sources & Access Checklist +- **On-chain RPC/archive**: Document credentials (Alchemy, Infura, self-hosted nodes) and rate limits. +- **Mempool / private relays**: Track availability of Flashbots-style endpoints or sequencer feeds. +- **Historical datasets**: Record storage locations under `data/` (Parquet/CSV), retention policies, refresh cadence. +- **Off-chain signals**: Centralised exchange order books, funding rates, oracle feeds. + +### Dataset Inventory (Initial) +| Path | Description | Refresh Cadence | Notes | +| --- | --- | --- | --- | +| `data/pools.txt` | Seed list of Arbitrum liquidity pool addresses (Uniswap v3, Sushi, Camelot). | Manual | Generated October 2025;

fee spreads; build Grafana panel. +3. **Timeboost Cost Model** + - Import DAO auction logs (2025-06–2025-09). + - Fit regression: expected slippage capture vs. slot price & revert probability (target EV > gas + fee). + - Integrate into execution pipeline as “bid or skip” decision gate. +4. **Simulation Backtests** + - Replay July–September 2025 blocks with actual gas & slot fees. + - Compare ROI for: (a) no priority, (b) selective Timeboost bidding, (c) spam bundle approach. + - Output to `reports/research/2025-10-XX_dex-arb-sim.md`. +5. **Operational SOP** + - Draft runbook: state sampling

simulation incorporating Timeboost costs. + +## Risks / Assumptions +- Timeboost auction dominance by two actors may raise slot costs faster than spreads widen. +- Liquidity fragmentation on new L3
