Crypto arbitrage,
priced on executable depth.

Every opportunity priced on executable depth

The engine behind the arbitrage tools in Apex OS, Arbitrage Nexus, does not rank opportunities by the top-of-book spread. It starts from the spread, subtracts the slippage of walking the order book at your size, adds carry where there is one, subtracts taker fees on both legs, subtracts a latency-risk term based on each venue’s volatility and measured round-trip time, and keeps a safety margin. The result must also persist for a confirmation window before it counts.

Spread Board: cross-exchange spreads, funding and basis

Spread Board is the client view of that engine, on the Premium plan. It shows live spreads for the same market across your exchanges, a venue matrix, a funding and basis board for spot-versus-perpetual and perpetual-versus-perpetual carry, and lead-lag between venues.

Smart Router: the best venue for every order

Even without arbitrage, prices and depth differ between exchanges. Smart Router, on the Trader plan, finds the best venue and the optimal split for an order across every connected exchange. It advises; you decide where the order goes.

Built to fail safely

Arbitrage execution runs in Shadow by default: paper fills on live order books, delayed by each venue’s measured latency, so results are not flattered by instant fills. Live execution has to be enabled on purpose, with dedicated trade-only keys per exchange.

Running cross-exchange arbitrage execution on your own accounts is set up together with you. Tell us about your setup.

• Immediate-or-cancel legs with idempotent order IDs: a lost acknowledgement is looked up, never re-sent
• A broken pair is repaired within a bounded slippage
• Transfers between exchanges are never automated, and withdrawal rights stay off
• Daily loss, unhedged exposure, failure, cooldown and position limits, plus a kill switch

On-chain: flash-loan and cross-chain arbitrage

Apex DEX Terminal takes arbitrage on-chain. Flash-loan arbitrage borrows from Kamino, marginfi or Solend, runs a swap cycle across Solana routes and repays, all inside one atomic transaction that is simulated in full before it is sent. If the cycle cannot repay, everything reverts: the loan principal is never at risk; the network fee is.

Cross-chain arbitrage prices the same asset on Solana, Ethereum, BNB Chain, Arbitrum and Arc, subtracts DEX fees, slippage and gas, and ranks the net edge. Once armed, it sells where the asset is dear and buys where it is cheap from inventory you already hold, with no bridge in the hot path and caps per trade and per day.
