Bridge (Cross-Chain)
Infrastructure that moves assets between blockchains — essential plumbing with a history of nine-figure hacks.
A bridge connects two blockchains, letting value move between ecosystems that can’t natively talk to each other — for example, using Bitcoin’s value inside Ethereum apps via a wrapped token. Typically you lock assets on chain A and receive an equivalent representation on chain B.
Bridges concentrate enormous value in single pieces of code, which made them crypto’s favorite heist target: several of the largest hacks in history (Ronin, Wormhole, Poly Network — over $600M each) were bridge exploits. Using major, battle-tested routes and moving in smaller tranches is standard risk hygiene.
