Shiba Inu Rolls Out Stronger Shibarium Bridge with New Security Features

Shiba Inu has rolled out a more secure version of the Shibarium Plasma Bridge, reinforcing the network’s BONE transfer system with two new safeguards; a blacklist mechanism and a seven-day withdrawal delay, designed to protect users, validators, and ecosystem liquidity from malicious activity.

Key Points

• Bridge Reactivated: The Plasma Bridge for BONE transfers between Ethereum and Shibarium is now live after a full-scale review.
• Dual Defense Added: Shibarium implemented a blacklisting system for malicious addresses and a 7-day finalization window for all BONE Plasma withdrawals.
• Independent Security Review: The upgrades were verified by the cybersecurity firm Hexens, following a rigorous multi-stage testing plan.

Bridge Reopens with New Safeguards

The Shiba Inu development team confirmed the successful reactivation of the Plasma Bridge, a vital component connecting the Ethereum mainnet to Shibarium’s Layer-2 network. This bridge enables the movement of BONE tokens, the ecosystem’s gas and governance token, between the two chains.

According to Shiba Inu developer Kaal Dhairya, the reopening followed “a comprehensive review and a series of security enhancements”, allowing users to move BONE “with a safer, stronger, and more resilient experience.”

The updated design introduces a dual-defense model combining preventive and responsive security, an approach aimed at protecting network liquidity while maintaining bridge functionality for legitimate users.

How the Delay and Blacklist Strengthen the Bridge

Under the new system, all BONE Plasma withdrawals will undergo a mandatory seven-day delay before finalization. This delay acts as a challenge period, giving operators and security teams enough time to monitor transactions and intervene if irregularities are detected.

“Plasma’s strength is fraud-resistance,” Dhairya explained. “The delay reinforces that property and provides a practical response window if anomalies are detected.”

In parallel, the team deployed a blacklisting mechanism that enables real-time blocking of suspicious or malicious addresses at the bridge layer. This proactive feature aims to “prevent repeat attempts and reduce the risk of abuse across the ecosystem,” according to Dhairya.

Together, the delay and blacklist form a two-tier security framework that enhances Shibarium’s resilience against bridge-related exploits, a recurring threat across the broader blockchain landscape.

Independent Validation and Hexens Audit

Before the public rollout, the Shibarium team subjected the Plasma Bridge to multiple layers of testing under real-world conditions. Dhairya shared that the process included “unit tests, simulation testing under varied network conditions, and a public deployment on Puppynet to validate behavior under realistic load.”

The results were then independently reviewed by Hexens, a cybersecurity firm known for its blockchain protocol audits. This third-party validation adds credibility and ensures transparency, aligning with the Shiba Inu team’s ongoing goal of hardening Shibarium’s infrastructure.

Next Steps: Expanding Token Coverage

Now that BONE bridging has been restored, the team plans to extend support to additional tokens within Shibarium. Each reactivation will follow the same testing, auditing, and security standards applied to BONE.

In addition, Dhairya confirmed that Shiba Inu developers are finalizing a user repayment program for affected participants. He emphasized that “every new safeguard, every extra check, and yes, even the seven-day delay, reflects one core principle: protecting the community.”

Why This Matters for the Ecosystem

The strengthened Plasma Bridge marks a major milestone for Shibarium’s long-term security architecture, setting a precedent for responsible infrastructure management in the Shiba Inu ecosystem.

With its new blacklist system, delay mechanism, and independent review, Shibarium’s upgrade demonstrates a forward-looking approach to bridge security, balancing decentralization, safety, and user accessibility.

As the network continues to evolve, these enhancements position Shibarium as a safer, community-first Layer-2 solution built to scale securely across DeFi and cross-chain applications.
