A bridge moves assets or messages between blockchains, often by locking on one chain and minting on another.
Bridges are frequent hack targets because they custody large TVL. Prefer well-audited, widely used routes.
In research workflows, Bridge is usually interpreted with Wrapped token, Layer 2, Total value locked, and Exploit rather than as a standalone signal. Throughput, finality, and fee markets determine user experience and where activity migrates during congestion.
