Across Protocol is a cross-chain bridge designed to provide efficient and secure transfers of assets across different blockchain networks, with a core focus on Ethereum and its Layer 2 solutions. It was launched to address the growing demand for interoperability while maintaining low transfer fees and reducing transaction times. By leveraging bonded relayers and liquidity pools, Across Protocol ensures smooth cross-chain communication, thus eliminating the traditional bottlenecks faced during asset transfers. The protocol is underpinned by a decentralised and trustless architecture, which enhances both security and user assurance. Its innovative design not only simplifies the movement of cryptocurrencies between blockchains but also contributes to the wider adoption of Layer 2 scaling solutions.
