Guides for getting started

Short, practical primers — the basics you need to install Smart Wallet and stay safer online.

What is a crypto wallet?

A crypto wallet holds the keys that prove you control addresses on a blockchain. It does not “store coins” the way a bank app stores a balance in a company database — the network tracks balances; your wallet signs transactions.

Smart Wallet is a browser extension wallet: it runs in Chrome, keeps software keys encrypted on your device, and can also work with Ledger hardware for Solana and EVM.

How to create or import

Create: Smart Wallet generates a new recovery phrase. Write it down offline (paper or metal), store it safely, and never type it into a website or chat. Anyone with that phrase can move your funds.

Import: Enter an existing recovery phrase or private key only inside the official extension UI — never into a form on a random site claiming to “validate” your wallet.

You can also connect Ledger for Solana and EVM so signing stays on the device.

How to connect Ledger and link EVM

  1. Connect your Ledger to your computer with USB, unlock it, and close Ledger Live. Bluetooth is not supported in the desktop extension.
  2. Open the Solana app on your Ledger. In Smart Wallet, open Accounts in the full wallet window and choose a Derivation # (0 is the first Ledger account).
  3. Click Connect Ledger and allow the device in Chrome's chooser. Select the connected Ledger account in Smart Wallet.
  4. To use EVM chains with that account, open the Ethereum app on your Ledger and click Link EVM. This links EVM to the selected Ledger account; it does not create a new account.

Keep the same derivation number when reconnecting the same account. Ledger support for Bitcoin and Sui is not available yet.

How to enable messaging on a Ledger account

  1. Select your connected Ledger account, then open Settings > Inbox > Ledger messaging devices in the full wallet window.
  2. Click Enable Ledger, allow the USB device if Chrome asks, and review the off-chain authorization on your Ledger. Approve it on the device to enable messaging for this account on this browser.

Smart Wallet creates a separate non-exportable key on this device and authorizes it for messaging. It signs mail actions without asking your Ledger to approve every message. You can revoke this device's messaging authorization from the same settings section.

This key is not your Ledger seed phrase or transaction private key. The authorization is not a blockchain transaction: it uses no gas, cannot move funds, and does not reveal your Ledger keys.

How to connect to a dApp

On a site that supports wallets, choose Smart Wallet (or WalletConnect when offered). Approve the connection request in the extension after checking the site URL.

Smart Wallet speaks Solana Wallet Standard, EIP-1193, and WalletConnect. Connecting a site is not the same as approving a spend — still review every signature request.

Common scams / never share your seed

  • Fake support: Nobody legitimate needs your seed phrase, private key, or “sync phrase” over email, Telegram, or Discord.
  • Airdrop / mint sites: Phishing pages mimic real apps and ask you to connect then sign a drain. Check the URL and read the confirm carefully.
  • Fake extensions: Only install from the official Chrome Web Store listing linked from this site.
  • Urgent pressure: Scammers create panic (“your wallet will be wiped”). Slow down and verify independently.

If you are unsure about a signature, deny it. Fail closed.

What non-custodial means

Non-custodial means you control the keys. Smart Wallet does not hold funds for you like an exchange account. Software keys stay encrypted on your device; Ledger keys stay on the Ledger.

That freedom comes with responsibility: protect your recovery phrase, keep backups offline, and understand that lost keys usually mean lost access — the team cannot “reset” a non-custodial wallet for you.
