Market Structure Evolution - The market structure around spot trading on Solana has evolved rapidly due to the rise of prop AMMs [1] - Prop AMMs provide tighter quotes by actively managing liquidity, updating quotes multiple times per second [1] - Prop AMMs' midpoint often tracks CEX prices like Binance, considered the "true" price [1] Arbitrage Dynamics - The CEX leg of CEX<>DEX arbitrage is shifting onchain [1] - Arbitrage bots now buy from stale onchain venues and sell to Prop AMMs, capturing spreads atomically in a single transaction [1] - Increased use of flash loans by arbitrage bots to capture these arbs [1] - A material amount of CEX<>DEX arbs are moving over DEX aggregators [1] - A majority of this volume is on the SOL-USD pair, the most liquid volatile asset on Solana [1] DEX Aggregator and Cyclic Arbitrage - There's a tight relationship between the percentage of DEX aggregator volume that moves over Prop AMMs and the percentage of DEX aggregator volume that is cyclic arbitrage [2] - Cyclic arbitrage is defined as transactions with the same input and output token, capturing the arbitrage transactions [2] Onchain vs CEX Price Discrepancies - When onchain price is $200 and Binance price jumps to $205, Props race to update their books to mirror Binance [3]
