Remove ETH Betting from SX Bet

Remove ETH betting from SX Bet and end SX emission incentives on ETH-based pools on SharkSwap

ETH-based betting on SX is a very small % of total betting volume (down to 5% of the total, from a peak of 15% early last year), and it has very high carrying costs as SX has to subsidize two LP pools on SharkSwap to make sure there is enough liquidity for ETH on SX Chain (currently emitting 7,000 SX/day + 9,000 SHARK/day).

Eliminating ETH-based betting will have a negligible impact on total betting volume, while removing 2.55m SX/year + 3.3m SHARK/year of emissions, which are better used elsewhere or else saved.
