here's a (near) zero-cost proposal to improve market quality on solana all things being equal, routers should send flow to AMMs which provide best quote first (time-priority) In practice, time-priority routing can be gamed if participants continuously undercut each other by small amounts. to avoid this, routers would need a minimum price improvement threshold where time-priority takes precedence over price-priority this change would impose a negligible cost on users but would reduce undercutting, encourage longer-lived quotes, and lower the number of transactions required to maintain prop AMMs quotes. overall improving both market quality and network efficiency
