- Shibarium Plasma Bridge for BONE is live again with stronger security features in place.
- A new blacklist tool now blocks risky wallet addresses before they can cause harm to the network.
- All BONE token withdrawals now have a seven-day delay to help stop fraud and protect user funds.
Shibarium has restored the Plasma Bridge for the BONE token, weeks after a flash loan attack disrupted the network. The hacking that occurred in September 2025 resulted in a loss of more than $4.1 million worth of crypto assets. Attackers used the Shibarium Bridge, which targeted Shibaswap and moved stolen money.
This reopening occurs after a complete security check and updating of the system to reinstate the bridge. The Shiba Inu development team stated that users can again transfer BONE between Ethereum and Shibarium.
New Security Features Introduced
The upgraded Plasma Bridge includes a blacklisting system that can flag and block suspicious wallet addresses. This update targets potential threats before they impact the network. The mechanism works directly at the bridge layer, increasing its ability to filter out high-risk activity.
This measure also helps in reducing abuse across the ecosystem. The feature allows for real-time responses by detecting suspicious behavior early. Developers believe this system will discourage similar attempts in the future.
Withdrawal Delay Added
In addition to the blacklist feature, the updated Plasma Bridge introduces a seven-day withdrawal delay for BONE transactions. This delay offers time for monitoring and investigating unusual activity. Security teams and validators can use the period to halt malicious actions.
The delay aligns with Plasma’s focus on fraud-resistance. It provides a window to act before finalizing a withdrawal. While it adds a buffer, it does not prevent users from accessing or initiating transfers.
This mechanism helps protect users while maintaining regular bridge functionality. It supports the project’s goal of preventing major disruptions, such as the one in September.
Background and Response
During the September attack, the network lost millions in assets. These were $1 million in Ether, $1.3 million in SHIB, and $717,000 in KNINE. The attacker was able to steal 4.6 million BONE tokens.
Developers quickly froze operations to contain the damage. Emergency actions prevented further exploitation. After this, a detailed review took place to identify vulnerabilities and prevent recurrence. Shibarium recently launched a $4 million refund plan after the major exploit and network shutdown.
The reactivation of the bridge follows these corrective measures. It includes both technological upgrades and process-level defenses. The Shibarium team focused on reinforcing weak points exposed during the breach. With these new systems in place, Shibarium aims to ensure a safer environment for token holders.
