Rainbow is a non-custodial Ethereum wallet designed to simplify the management of cryptocurrencies, NFTs, and decentralized finance (DeFi) assets. Launched in 2019, it offers a user-friendly interface that appeals to both newcomers and experienced users. The wallet supports multiple networks, including Ethereum mainnet and Layer-2 solutions like Polygon, Optimism, and Arbitrum, enabling seamless cross-chain asset management.
Key features of Rainbow include built-in token swapping and bridging, allowing users to exchange assets without leaving the app. It also provides comprehensive NFT support, enabling users to view and organize their digital collectibles across supported networks. Additionally, Rainbow integrates with the Ethereum Name Service (ENS), simplifying address management by allowing users to send and receive assets using human-readable names.
Security is a priority for Rainbow; as a non-custodial wallet, it ensures that users retain full control over their private keys. The wallet also incorporates Flashbots protection to mitigate front-running and other malicious activities. To enhance user engagement, Rainbow introduced a points program in December 2023, rewarding users for on-chain activities such as swaps. In September 2025, the company announced plans to launch its native RNBW token, converting these points into an on-chain asset to further incentivize user participation.
Rainbow is available as a mobile application for iOS and Android devices, as well as a browser extension, providing a versatile and accessible platform for managing digital assets.
