Smart Contract Bridge

Definition ∞ A smart contract bridge is a mechanism that allows assets and data to transfer between different blockchain networks using smart contracts. These bridges facilitate interoperability by locking assets on one chain and minting equivalent wrapped tokens on another, all managed by automated contract logic. They enable decentralized applications on separate blockchains to communicate and exchange value without relying on a central intermediary. The security and integrity of these bridges are paramount for cross-chain asset transfers.
Context ∞ Smart contract bridges are critical infrastructure for connecting isolated blockchain ecosystems, thereby expanding the utility and liquidity of digital assets. The security of these bridges is a significant concern, as they represent a common target for exploits due to the large value locked within them. Discussions often focus on developing more trust-minimized security models and robust auditing practices for these complex systems. Enhancing the safety and efficiency of cross-chain bridges is a major area of ongoing development in the blockchain space.
