Rainbow's extension is built to seamlessly connect every type of wallet, even without importing a seed phrase. If you've ever wanted to quickly connect your exchange or hardware wallet address, or peek at an influencer's transactions and portfolio, Rainbow has your back. Watch a wallet address and connect it to a dApp. It's that simple.
You can watch new wallets in Rainbow by opening the Wallet Switcher, choosing "Add another wallet" and "Watch an Ethereum address", then entering a public address or ENS. These wallets are treated just like your hot wallets, except you can't sign or send transactions. It's Ethereum in read-only mode.
