Picking one

• No crypto experience? Sign in with email or passkey. We'll create an embedded wallet for you automatically. Read Embedded wallet vs your own wallet before you do — there are real trade-offs.
• Already have a wallet? Connect MetaMask, Coinbase Wallet, Rainbow, or anything WalletConnect-compatible. You stay in full control of your keys.

What 4rho cannot do

We never see your private key. We can't sign on your behalf, can't freeze your balance, and can't reverse a transaction you've signed. If you lose access to your wallet, we cannot restore it. Treat your wallet like cash.

Don't see your wallet?

Most wallets work via WalletConnect. If yours doesn't appear in the connect modal, look for a "WalletConnect" or "Other" option in your wallet's connection menu — it'll let you scan a QR code from 4rho.

If you're stuck, open a support ticket with the wallet name and the device you're using.
