LINK: net CEX→DEX edge after gas
CEX–DEX arbitrage net of costsdeterministicresolved scored on exactness vs the frozen snapshot, tolerance 2.0 bps
LINK trades at 11.932214309264117 on the CEX lane and 11.935065977869279 on the deepest traded Ethereum pool. Gas is 0.06 gwei, ETH is 2410.281957154694, a swap burns 150,000 gas, same chain so no bridge cost. For a 10,000 USD notional, what is the NET edge in basis points (DEX minus CEX, minus gas as bps of notional)? Negative means no trade.

data: cex_px, dex_px, gas_gwei, eth_usd, gas_units, notional_usd, bridge_cost_usd factors: price gap, (DEX - CEX) / CEX in bps: 11.9351 against 11.9322 is 2.39 bps (0.7), gas: 0.0581477 gwei x 150000 units x ETH 2410.28 is 0.02 bps of the 10000 USD notional (0.25), bridge cost 0.00 bps (ethereum) (0.05) rejected: the snapshot's naive edge (2.39 bps): the price gap alone, it ignores gas; CEX minus DEX: the puzzle defines the edge as DEX minus CEX, so the sign would flip |
