David Schwartz who co founded the XRP Ledger dropped a clever transaction reservation scheme to crush front running on the network’s decentralized exchange and automated market maker 🖤 his idea sparked from a sharp post by the XRP focused account XRPresso io highlighting how validators and connected nodes peek at pending trades before ledger close.
XRPL Front Running Worries 🌙
Transfers often linger in a public queue as XRPresso noted allowing savvy players to eye profitable sandwiches and flood similar entries for better slots in the hash based ordering formula ✨ this setup risks leaving everyday traders in standard wallets disadvantaged while sharp operators snipe value.
Schwartz called the core issue valid yet noted equal visibility for all unless validators collude which would show on chain and get them booted from trust lists. He shared in a tweet that multiple validators conspiring would be very obvious to everyone exactly who was doing this. No real attempts have surfaced beyond proofs of concept mainly due to tough profitability math needing both high and low liquidity at once.
His fix lets users submit a reservation tx with a ledger sequence and ID plus a fee for guaranteed priority if broadcast before close ensuring your move beats any formed after disclosure.
DeFi Front Running Chat 💎
XRPresso sees the reservation as interesting but adds cost and misses pre validation secrecy favoring confidential pending tx details like other chains use. The broader DeFi headache shows in Changpeng Zhao’s push for a dark pool perps DEX with zero knowledge crypto to mask orders till execution.
