Incidents by blockchain.
Every chain has a unique attack surface. Bridge protocols multiply the exposure across all of them.
Ethereum
The most targeted chain. High TVL, complex DeFi composability, and a decade of deployed contracts create a dense attack surface. Most exploit patterns were pioneered here.
Solana
Account model and parallel execution create unique vulnerability classes. Lazarus Group has heavily targeted Solana protocols in 2025–2026 through long-term social engineering.
BNB Chain
High frequency of flash loan attacks due to abundant low-liquidity AMM pools. BSC fork proximity to Ethereum code means many exploits are direct ports of known attack patterns.
Arbitrum
Layer 2 bridge architecture introduces cross-layer message verification risks. Growing TVL migration from mainnet brings exploitable protocols.
Cross-chain
Cross-chain bridges represent the highest-value attack targets in DeFi. Forged proofs, validator collusion, and DVN spoofing have drained billions from multi-chain protocols.
