What is Rainbow?
Rainbow is a mobile-first Ethereum wallet focused on L2 networks, with clear views of tokens and NFTs.
How Rainbow works
Swaps and bridges in Rainbow go through its RainbowRouter contract, deployed on every supported network.
You pick tokens, set the amount, and on the review screen see the minimum received, the Rainbow fee, slippage and gas. A Flashbots toggle sends the transaction privately to protect against front-running and sandwich attacks. Rainbow blocks swaps for some fee-on-transfer tokens because their extra fees make trades fail.
Rainbow launched the RNBW token on February 5, 2026, with a total supply of 1 billion. Users who stake RNBW in the app get part of their swap fees back in RNBW: 25% at 5,000 staked, 50% at 10,000, 75% at 15,000 and 100% at 20,000. Users without stake earn 10% of swap fees back as Rainbow Rewards, with Rainbow buying RNBW on the market to refill the reward reserve.
How to start with Rainbow
- Download Rainbow for iOS or Android.
- The iOS app, sold by Rainbow Studio, Inc., needs iOS 15.1 or later and manages assets on Ethereum mainnet, Polygon, Optimism, Arbitrum, Base and Zora.

Rainbow fees and limits
- Unstaking RNBW costs a 10% exit penalty, paid in RNBW to other stakers over seven days.
- At the top Black tier, Rainbow says 100% of your swap fees come back as staked RNBW.
Rainbow shows its fee on the review screen before every swap, but its support pages do not state a fixed rate. You also pay network gas and, on card purchases, the provider's fees.
Risks to know before using Rainbow
- Rainbow's support page warns that anyone can create a token under any name, so check contract addresses before you swap.
- Blockchain transactions cannot be refunded.
- RNBW team and investor tokens start vesting on February 5, 2027, after a 12-month cliff.
- Rainbow Studio's terms make you responsible for setting sufficient network fees, and say it has no obligation to help fix a transaction stuck for lack of fees.
