A two-part ReservedTxns mechanism would aim to curb sandwich attacks on XRPL's native DEX and AMM before the idea goes to a validator vote.
David Schwartz has proposed a two-part ReservedTxns mechanism for XRPL after renewed claims that front-running and sandwich attacks had resurfaced. The proposal is designed to help prevent traders or bots from exploiting visible pending activity on XRPL's native DEX and AMM by reserving transaction execution in advance. The update adds detail to an earlier debate over transaction ordering on XRP Ledger, where sequencing can affect execution quality for on-chain trading and other user activity. The proposal is now framed as a specific mechanism that would go before validators for a vote, putting fresh focus on how XRPL balances transparency, execution fairness and resistance to manipulation.
