Deep Dive
1. Plasma Bridge Relaunch (14 October 2025)
Overview: Shibarium’s BONE Plasma Bridge resumed operations after a month-long freeze caused by a validator key breach. The update prioritizes attack prevention and user fund safety.
Key changes include a 7-day withdrawal delay for all BONE transfers, allowing time to flag suspicious activity, and a proactive blacklist system at the bridge layer to block malicious addresses. Code audits by Hexens confirmed no protocol-level vulnerabilities.
What this means: This is bullish for BONE because it restores cross-chain liquidity between Ethereum and Shibarium while adding safeguards against large-scale exploits. The delay trade-off enhances security but may temporarily slow user withdrawals. (Source)
2. RPC Infrastructure Migration (2 November 2025)
Overview: Shibarium deprecated its legacy public RPC endpoint, mandating a shift to decentralized node providers to reduce centralization risks.
The old RPC (used for wallet/blockchain communication) will be disabled by mid-November. Developers must now integrate with multiple node providers, distributing network access points.
What this means: This is neutral for BONE – while improving long-term resilience, the migration requires immediate developer effort to avoid service disruptions. Decentralization aligns with crypto ethos but complicates short-term maintenance. (Source)
3. Reimbursement Framework (3 October 2025)
Overview: Post-exploit, developers outlined a plan to compensate users who lost funds in the September bridge attack, pending final approvals.
The framework involves smart contract adjustments to allocate recovered assets (4.6M BONE frozen from the attacker) and protocol fees toward victim repayments.
What this means: This is cautiously bullish for BONE, as restoring user trust is critical. However, delayed implementation (no timeline yet) and reliance on recovered funds introduce execution risks. (Source)
Conclusion
BONE’s code updates reflect a security-first rebuild after September’s exploit, balancing fraud prevention (7-day withdrawals) with ecosystem growth (cross-chain revival). While decentralization efforts and reimbursement plans signal maturity, can Shibarium sustain developer engagement amid tighter security trade-offs?
