A single blockchain no longer dominates the crypto industry. Users commonly move assets across Ethereum, Solana, BNB Chain, Base, Polygon, and many other smaller networks. That way, they get access to lower-fee decentralized finance (DeFi) apps, NFTs, and gaming platforms.
This is done by using a technology known as a crypto bridge. They are therefore an essential part of the Web3 infrastructure, but also its biggest vulnerability. Some of the biggest hacks in history happened when bridges were targeted, proving how risky they are.
What is a Crypto Bridge?
The term refers to a protocol that allows digital assets and data to move between two separate blockchains. Most blockchains operate independently and therefore can’t recognize transactions or tokens from other networks. Bridges create a secure network, allowing it to happen.
For example, a user owning ETH on Ethereum who wants to use a DeFi application on Base, where transaction fees are much lower, doesn’t need to
