Recorded history — the last 72 builds
1,773 builds recorded · window shown starts 2026-10-19T23:35Z. One point per distinct snapshot build, recorded live — never estimated or backfilled.
Read this before acting on anything above. GROSS cross-venue spreads from live pool state, BEFORE gas, MEV and any slippage beyond the optimal size. Not a profit estimate and not trade advice. Venues below the liquidity floor are excluded because a spread against a dust pool is an artefact, not an opportunity. Every number is a live on-chain measurement; nothing here is estimated or backfilled.
The full API behind this page — per-pair spreads, per-venue depth, slippage for your exact trade
size, USD price feeds with liquidity-backed confidence, and this scan as JSON with your own filters.
