What can SlateProof do for you in South Dakota?
With no tracked sportsbook in South Dakota, the lane that applies is exchanges-only arbitrage: every leg at a US exchange, 6 pairs of the 4 exchanges to scan.
- Sportsbook offers do not apply here; exchange legs need resting depth and carry their own fees.
