XRP Bridge Drained of $200K After Attacker Exploited Deposit Validation
An attacker drained approximately $200,000 worth of XRP from a cross-chain bridge by creating unbacked XRP on another blockchain and exchanging it for real reserves. The bridge operator halted the service and filed a complaint with the FBI; audits had failed to detect the flaw.

Story Updates
- Updated Aug 12, 2026, 05:02 PM: Added reporting that multiple independent audits failed to detect the deposit validation flaw before the exploit occurred.
How the Attack Unfolded
An attacker created fake XRP deposits on a connected blockchain, exploiting the bridge's deposit validation logic to treat the unbacked tokens as legitimate. The attacker then exchanged these fraudulent deposits for genuine XRP held in the bridge's reserve, draining approximately $200,000 worth of the real asset before the vulnerability was detected. According to Decrypt, the flaw remained undetected despite multiple independent audits of the bridge's code.
Bridge Halted, Investigation Underway
The bridge operator halted the service immediately upon discovery of the exploit and filed a complaint with the FBI. According to CryptoPotato, the stolen XRP was subsequently converted to ETH, routed through THORChain, and ultimately sent to Tornado Cash, suggesting the attacker took steps to obscure the fund flow across multiple protocols and privacy-focused services.
Technical Implications
The incident underscores a recurring vulnerability in bridge security: deposit validation systems that do not adequately distinguish between native assets and wrapped or cross-chain representations. The fact that the vulnerability survived multiple audits raises questions about the depth of bridge security review processes. Similar exploits have affected other bridge protocols in recent years, typically resulting from gaps between the verification layer and the reserve management system.
Why It Matters
For Traders
Bridge exploits historically spike scrutiny on affected assets and connected protocols; monitor XRP pair liquidity and volume on impacted venues for spillover effects.
For Investors
Cross-chain security breaches erode confidence in bridge infrastructure; that audits missed this flaw raises questions about the rigor of bridge security certification.
For Builders
Multi-layer deposit verification independent from reserve reconciliation is critical; this incident shows audit alone cannot catch validation logic flaws without structural separation.
