Will we have a Cardano Browser Wallet? Something like Metamask on Ethereum
We have Yoroi Web extensión for Chrome, Firefox and Edge.
There's the open-source Nami Wallet – a browser-based wallet extension to interact with the Cardano blockchain. You can run it on Edge, Brave, Chrome and any other chrome-based browsers. As you can imagine, the Berry Pool's wallet does support staking. And it has nice and simple UI.
The user of Nami wallet can only import one seed phrase, but from that one they can create sub-accounts. Each account is its own wallet and independent from each other.
Also, you can try 4 other web wallets that support ADA and tokens:
It's called Yoroi. It's a browser extension like Metamask.
There is something similar, though it's more a "web wallet", not a browser plugin wallet like Metamask. Checkout AdaLite
GeroWallet was launched a couple of weeks ago and it works exactly like Yoroi.
