An attacker drained close to 200,000 XRP from the Coreum cross-chain bridge within a quick span of 97 minutes on Aug. 9, exploiting a flaw in how the bridge confirmed deposits rather than any weakness in the XRP Ledger itself.

A cross-chain bridge connects two separate blockchains, letting users move assets between networks that cannot talk to each other directly.

The Coreum bridge let users lock XRP on the XRP Ledger and receive an equivalent number of tokens on Coreum’s network.

According to on-chain analysis, the bridge held roughly 200,410 XRP before the incident and was left with just 493.5 XRP afterward.
