Shibarium has announced the reactivation of the Plasma Bridge for the BONE token, with the move coming a few weeks after a network exploit that saw attackers siphon more than $4.1 million via a flash loan attack.
Summary
- Shiba Inu reactivated the BONE Plasma Bridge following a recent freeze.
- The exploit that saw $4.1 million in assets stolen happened after an attacker gained 4.6 million BONE.
- Prices of SHIB, BONE and KNINE fell amid the exploit in September.
The Shiba Inu team has announced the reopening of the Plasma Bridge for BONE on the Shibarium Bridge. According to a blog post, the update includes blacklisting functionality designed to bolster ecosystem security.
“We’re pleased to share that the Plasma Bridge is back online for BONE, following a comprehensive review and a series of security enhancements. Users can once again bridge BONE between Ethereum and Shibarium with a safer, stronger, and more resilient experience,” the Shib team wrote.
What’s new for the Shibarium bridge?
According to the announcement, the reactivated platform taps into a “proactive blacklisting system that lets us flag and block suspicious addresses at the bridge layer.”
The blacklisting functionality will help prevent potential future attacks and will address risks of abuse across the ecosystem.
Shibarium has also added a 7-day withdrawal delay for all BONE Plasma withdrawals. The finalization delay offers a buffer to operators and security teams, with the delay giving them time to monitor and respond to suspicious activity. The move adds a layer of defense without impacting user access.
“Plasma’s strength is fraud‑resistance. The delay reinforces that property and provides a practical response window if anomalies are detected,” the platform noted.

The Shib team’s quick response helped stem further losses. After an initial freeze, the developers successfully reactivated the bridge, with reinforced security at the center of the fresh launch.
