Two flavors of arbitrage under one roof. Spot Arbitrage captures price gaps across your connected exchanges (cross-exchange, triangular, or DEX-DEX). Funding Arbitrage and Cross-Venue Funding Arb harvest funding-rate flows delta-neutral across a funding interval. Vant8 handles the mechanics — venue rate-limit spacing, auto-rebalance of stablecoin float, USDC/USDT depeg circuit breakers, and reduce-only exits — so long-running strategies don't stall or drift.
Capture price gaps across your connected exchanges — cross-exchange (spot pair priced better elsewhere), triangular (three-leg loop inside one exchange), or DEX-DEX (same pair on two on-chain venues).
Distinctive · Three modes in one strategy; bidirectional scan (arb in both directions) plus optional auto-rebalance that pre-positions inventory using local USDT — no cross-venue withdrawals needed; emergency-liquidation kill switch built in.
Open in-app guide →Cash-and-carry: long spot and short perp on the same venue to collect the funding rate.
Distinctive · Rejects Hyperliquid (no spot leg); requires both SPOT and FUTURES connections on the venue.
Open in-app guide →Two perp legs on different venues, paid to hold each side of the trade as the funding rates flow.
Distinctive · USDC/USDT depeg circuit breaker; Hyperliquid is supported as one leg.
Open in-app guide →The three strategies split cleanly into two profit models: capture a price gap (Spot Arbitrage) or capture a funding-rate flow (Funding Arb, Cross-Venue Funding). Each has its own mechanics and its own risks.
When the same asset trades at different prices across venues, the strategy buys on the cheap side and sells on the expensive side simultaneously. Cross-exchange (two CEXs), triangular (three legs inside one CEX), or DEX-DEX (two on-chain venues on the same chain) — one strategy, three modes.
When perp longs are paying shorts (or vice versa), the strategy positions itself on the side that gets paid and hedges the other side so the price exposure cancels. Both funding-arb strategies are delta-neutral by construction; returns come from the funding rate, not from price moves.
Spot Arbitrage scans opportunities in both directions (buy on A / sell on B, and buy on B / sell on A) so inventory drifts back and forth naturally. When one venue runs low on the base asset, the strategy can also use local USDT on that venue to pre-position more inventory — all trade-only, no withdrawal permissions or cross-venue transfers needed.
Cross-Venue Funding Arb often runs one leg in USDC and one in USDT. If the two stablecoins diverge on a peg event, the strategy pauses rather than holding through what looks like an arb but is actually depeg risk.
Funding Arbitrage requires a spot leg. Hyperliquid has no Vant8-supported spot, so the strategy is flagged at creation rather than deployed into a state that can't close cleanly. Cross-Venue Funding Arb does accept HL as one of its two perp legs.
These strategies are not racing sub-second order-book moves between venues. Spot Arbitrage acts on gaps that survive at least one execution cycle; funding-arb operates on the funding-interval timeframe (one to eight hours depending on the venue). Latency-racing between venues is a different game.
Auto-rebalance is trade-only: it uses local USDT on a low-inventory venue to buy the base asset there. Combined with the bidirectional arb scan, this keeps inventory alive across venues without ever touching a withdrawal endpoint. The API keys stay trade-only, exactly as connected.
Liquidation on either leg of a funding arb ends the trade unevenly. Price-gap arbs can close in transit if a leg fills at a worse price than expected. Funding-rate volatility, exchange API outages, withdrawal queues, and stablecoin depegs are all real exposures. Vant8's arb strategies capture their spread, they don't eliminate operational risk.
Available size is constrained by venue funding caps, exchange rate limits, and your account margin. Every account has a maximum scale at which the operational risk stops being worth the arb capture — the sweet spot is smaller than you might expect.
Super User unlocks both arbitrage strategies. You'll need a spot connection and a perp connection on the same venue for Funding Arb, or two perp connections for Cross-Venue.
