XRP Ledger–tx bridge bug lets attacker mint bridged XRP from phantom deposits, draining about 200,000 in 94 payments

AI Market Summary
A bridge connecting XRP Ledger to the tx chain was drained after an exploit in deposit-detection logic allowed minting unbacked bridged XRP against non-existent deposits, then swapping into real XRP. About 200,000 XRP exited via 94 payments, each signed by 17 of 28 relayers, indicating validator attestation did not prevent the failure. XRPL was not compromised, but confidence in bridged XRP backing and related liquidity is impaired.

A bridge connecting the XRP Ledger to the tx chain was exploited through a flaw in its deposit-detection logic. The attacker crafted transactions with no real deposits, minted bridged XRP on the tx chain, then swapped it back into real XRP. About 200,000 XRP was transferred out across 94 payments, each correctly signed by 17 of 28 relayers. Ripple’s ledger was not compromised, but txEcosystem said bridged XRP on its chain is no longer fully backed.
