Shibarium, the Shiba Inu ecosystem’s Layer-2 blockchain, has officially reactivated the Plasma Bridge for the BONE token, marking a major step toward restoring confidence after a recent network exploit that drained more than $4.1 million through a flash loan attack.
Shiba Inu’s Bridge Returns Stronger
According to an announcement from the Shiba Inu development team, the Plasma Bridge which allows users to transfer BONE between Ethereum and Shibarium has been fully reopened following a comprehensive security review and several new protection measures.
“We’re pleased to share that the Plasma Bridge is back online for BONE, following a comprehensive review and a series of security enhancements,” the team wrote.
“Users can once again bridge BONE between Ethereum and Shibarium with a safer, stronger, and more resilient experience.”
The reopening comes after a temporary freeze put in place in September 2025, when a critical exploit targeted the bridge and resulted in significant losses.
Enhanced Security: Blacklisting and Delay Features
The revamped Plasma Bridge introduces a new “proactive blacklisting system” designed to detect and block suspicious addresses at the bridge layer.
This system enables real-time identification of potentially malicious wallets, helping prevent further attacks and protecting user funds.
Additionally, Shibarium has implemented a 7-day withdrawal delay for all Plasma-based BONE withdrawals. This delay acts as a security buffer, giving developers and security teams time to investigate and respond to any irregular activity before funds can be finalized.
“Plasma’s strength is fraud-resistance,” the team explained. “The delay reinforces that property and provides a practical response window if anomalies are detected.”
These measures mark a key evolution in Shibarium’s on-chain defense strategy, reflecting the project’s shift toward more proactive risk mitigation.
Recap: The $4.1 Million Hack
The reactivation follows the September 2025 exploit in which attackers siphoned roughly $4.1 million worth of digital assets from the Shibarium Bridge.
According to developer Kaal Dhairya, the attacker gained access to 4.6 million BONE tokens, using them in a flash loan exploit that affected several liquidity pools.
Stolen assets reportedly included:
- $1 million in Ether (ETH)
- $1.3 million in SHIB tokens
- $717,000 in KNINE
The Shiba Inu team’s swift action helped contain the damage by freezing bridge operations immediately after the incident. The team then conducted a full audit and security overhaul, culminating in this week’s relaunch.
Market Impact and Community Response
Following the September exploit, SHIB, BONE, and KNINE all saw double-digit declines as investor sentiment weakened. Since then, prices have stabilized, with renewed optimism emerging around the relaunch of key infrastructure components like the Plasma Bridge.
Developers emphasize that the reactivated bridge is a stronger, more secure version a crucial milestone in Shibarium’s journey toward full ecosystem recovery.
The Bottom Line
The reopening of Shibarium’s Plasma Bridge for BONE signals a major comeback for the Shiba Inu ecosystem following one of its most severe attacks to date.
By introducing blacklisting capabilities, fraud-resistant delays, and stricter monitoring, the Shibarium team aims to rebuild trust and prove its commitment to long-term ecosystem security.
If successful, this upgrade could position Shibarium as a safer, more resilient Layer-2 platform, setting new standards for transparency and protection in community-driven blockchain projects.
