The Shiba Inu community has successfully reactivated the BONE transfers via the Shibarium Plasma bridge, reinstating the ability to deposit and withdraw between Ethereum and its layer-2 ecosystem after enduring a security challenge that led to a pause of this functionality for a month. In a communication dated October 14, core contributor Kaal Dhairya shared that the Plasma Bridge is “operational once more for BONE, following an exhaustive evaluation and a variety of security upgrades,” reassuring users that they can engage with BONE in a “safer, stronger, and more resilient environment.”
Resumption of Shibarium Bridge Services
This reboot arrives after the Shibarium bridge faced interruptions in mid-September due to a validator-key security breach that allowed for unauthorized asset exits across the PoS bridge. In a report released on September 21, Dhairya detailed that “on September 12, 2025 at 18:44 UTC, unauthorized validator signing authority was exploited to execute a malicious exit on the PoS bridge, withdrawing several assets,” compelling the team to undertake swift containment actions alongside a comprehensive security enhancement plan. They indicated intentions to release full technical particulars once conditions allow, noting that “bridging would remain limited during the containment and hardening process.”
As part of the renewed rollout, the Shibarium team is framing the reopening of the BONE bridge as a strategic phase in reinstating services, supported by new operational and policy-level checks. A significant adjustment for users is the introduction of a mandatory delay before withdrawal completions: “All Plasma withdrawals for BONE will now incorporate a 7-day finalization pause. This buffer offers operators and security personnel a window to observe and react to any atypical activity before funds are finalized—enhancing security without obstructing user access.” This decision has been depicted as strengthening the bridge’s fraud-resistance measures.
Additionally, a new feature introduced is the proactive blacklisting of suspicious addresses at the bridge layer. The Shiba Inu team explained that this novel functionality allows for the identification and blocking of addresses deemed suspicious, aiming to prevent repetitive misuse throughout the ecosystem. They emphasized that all crucial code modifications have undergone external audits: “Every significant change was scrutinized by Hexens, introducing an additional layer of professional validation.” The relaunch proceeded after a validation sequence that encompassed unit tests, comprehensive simulations, deployment on the public testnet (“Puppynet”), and “multi-timeframe” oversight before full activation.
The update from October 14 also sheds light on another aspect of the September incident linked to KNINE and minor OSCAR token transactions. The Shiba Inu team revealed that the perpetrator “extracted and sold roughly $600 worth of OSCAR tokens but bypassed the 5 ETH recovery incentive for KNINE tokens,” which now remain inoperable for the attacker. The KNINE bounty previously announced has “elapsed,” but the team is considering “one final, conditional bounty (amount to be decided) for the complete return of all KNINE held by addresses under attacker control,” emphasizing that partial recoveries are unacceptable and that details will only appear on verified platforms.
While at this point only BONE is functional on the Plasma bridge, Shibarium is signaling a broader strategic plan. The team intends to “roll out gradual re-enablement for additional tokens” and is “working to finalize an equitable and transparent reimbursement framework for users affected,” with particulars to be disclosed at a time deemed safe. The announcement stresses a cautious approach following the September incident: “Safety first: We won’t disclose details that could be exploited while security efforts remain ongoing. Expect thoughtful, verifiable updates.”
The context surrounding the month-long service interruption highlights significant behind-the-scenes remediation efforts. In late September, Shibarium introduced its strategy concerning rotations of validator participants, migrations of contract oversight to multi-party hardware custody, targeted safeguards at the contract-level, ongoing live monitoring, coordination with exchanges, and collaboration with independent security experts. The September 21 update also acknowledged deficiencies in decentralization among validator operations and outlined a hardening strategy, which is still progressing in cooperation with Hexens. Restoration is contingent upon securing third-party validations and successful testing drills.
The reopening signifies a vital avenue for validators, liquidity providers, and users who depend on the mobility of BONE between Ethereum and Shibarium. As the post concludes, the new protocols—such as address blacklisting and the 7-day delay—are designed to synchronize the user experience with the practical demands of operating a Plasma-style system in adversarial scenarios: “Every new safeguard, every additional verification, and yes—even the 7-day delay—reflects one core principle: protecting our community.”
As of the latest reports, the Shiba Inu (SHIB) token is trading at $0.00001060.
