The Shibarium Bridge is the Ethereum-to-Shibarium cross-chain bridge operated by the Shiba Inu ecosystem team, enabling transfer of SHIB, BONE, LEASH, and other tokens between Ethereum mainnet and the Shibarium Layer 2 network. The bridge suffered two major incidents: a chaotic launch in August 2023 that left approximately $1.7 million in ETH temporarily inaccessible, and a far more serious exploit in September 2025 in which attackers compromised 10 of 12 validator signing keys to drain approximately $3–4.1 million in assets. The bridge was partially restored in October 2025 following a security overhaul, but hack victims faced ongoing repayment delays and independent analysts raised persistent concerns about centralization and governance design.
