Nope! It's just one click to install. No need to sign anything.

Nope! We have no access to your wallet/seedphrase/private keys. To move assets you will still need to sign in your wallet as per usual.

We work with almost all web3 wallets! For example, we will pop up before Metamask, Coinbase and other wallets that use similar methods to them like Rabby, XDEFI, Frame and Taho. Some wallets like OKX are currently incompatible, but that may change as we make updates. We currently don't work with Wallet Connect.

Not yet! We're in beta testing for iOS. A full release will be announced when it's ready.
