- The XRPL front-running debate grows as critics question transaction privacy and fairness for everyday traders.
- Joel Schwartz disputes validator advantages, saying public transaction visibility limits coordinated front-running risks.
- XRPL developers face calls for privacy upgrades as DeFi growth increases focus on trading protections.
XRPresso.io has renewed concerns over front-running on the XRP Ledger, warning that ordinary traders remain at a disadvantage when transactions are waiting to be confirmed.
In a post on X, the platform said validators and well-connected nodes can see pending transactions before they are finalized, allowing sophisticated traders to place competing orders ahead of other users. It called on the XRPL Foundation and developers to strengthen transaction privacy as activity on the network continues to grow.
The platform said attackers can watch pending trades and time their transactions to secure a better position in the ledger’s processing order. It added that current safeguards have not fully stopped sandwich attacks, leaving regular traders with poorer trade execution while more sophisticated participants capture the gains.
Joel Katz Responds With Mitigation Arguments
Former Ripple CTO David “JoelKatz” Schwartz acknowledged the concerns but pushed back on claims that validators have a special advantage in front-running trades. Responding on X, Schwartz said pending transactions are visible before a ledger closes, meaning anyone watching the network—not just validators—can try to act on that information.
He also said any attempt by validators to work together would be easy to spot because every proposal and validation is recorded publicly. While proof-of-concept demonstrations have shown front-running is possible, Schwartz said there have been no confirmed cases of such attacks on the XRP Ledger. He added that front-running is difficult to profit from consistently because trading conditions do not often create reliable opportunities.
Debate Grows as XRPL Expands DeFi Ecosystem
As a possible solution, Schwartz proposed a transaction reservation system designed to make sandwich attacks harder to pull off. He said users could reserve their place in the transaction queue by paying a fee and submitting a second transaction, giving them priority once the reservation is confirmed.

XRPresso.io welcomed the idea but argued it would not fully solve the problem. The platform said traders with faster connections would still have an advantage and maintained that limiting the visibility of pending transactions is a better long-term fix.
The debate comes as the XRP Ledger continues to expand its decentralized finance capabilities through proposed upgrades, including improvements to its automated market maker, native lending, and programmable escrow features. Separately, Ripple and JPMorgan have highlighted tokenized U.S. Treasury settlement as one of the emerging use cases for blockchain technology.
XRP traded between $1.03 and $1.05 over the past 24 hours, while trading volume rose 25% after the United States and Iran suspended military strikes.
