about us

Aurora is working in the blockchain industry and helps developers and users to capture the full benefits of the Ethereum network by creating an opportunity to scale the ecosystem.

Aurora Labs builds the Aurora Ecosystem which mainly consists of two components: Rainbow Bridge and Aurora Engine. Rainbow Bridge is a fully trustless and decentralized bridge that interconnects Ethereum and NEAR ecosystems. The Bridge team is responsible for developing the Rainbow Bridge, its related services, and infrastructure that connect Ethereum and NEAR ecosystems together. Aurora Engine is an EVM built on the NEAR Protocol, delivering a turn-key solution for developers to operate their apps on an Ethereum-compatible, high-throughput, scalable and future-safe platform, with low transaction costs for their users.
