Market universe
A registry, not a hard-coded pair.
Markets earn their place. Each candidate passes a sixteen-point capability preflight before it is scanned alongside the baseline market, and its status is disclosed here as integration status — never as a profitability claim.
Baseline
ETH/USDC is the control market.
The baseline exists so every change to the engine can be measured against a stable, deeply liquid reference before it is trusted anywhere else.
- ETH/USDCBaseline control market. Live market data across both Base DEXs and the connected order books.Live
Expanded universe
Additional Base assets under verification.
Expanded markets run as a separate cohort with isolated data, so nothing they produce can contaminate the baseline record.
- cbBTC/USDCUnder preflight. Base leg holds cbBTC while the exchange leg holds BTC — separate inventory with rebalancing friction.Testing
- AERO/USDCUnder preflight. Base-native liquidity with partial centralized coverage.Testing
- AAVE/USDCUnder preflight across Base pools and centralized order books.Testing
- AIXBT/USDCWatchlist. Limited centralized coverage; identity and depth still being verified.Watchlist
- USDT/USDCUnder preflight. Stable-to-stable microstructure with very small nominal dislocations.Testing
- EURC/USDCWatchlist. FX-style pair with limited centralized coverage.Testing
Preflight
Sixteen checks before a market is scanned.
A market that fails any check is held back and the failing check is recorded. Coverage is expanded by passing verification, not by adding tickers.
