SubWallet Extension provides flexible account management that supports multiple blockchain networks and account types. Manage all your accounts from a single, secure interface.

​
Creating Accounts

SubWallet offers multiple ways to create and import accounts to suit your needs.

​
Create with Seed Phrase

Generate a new account using a secure seed phrase (also called a mnemonic or recovery phrase).
1

Generate seed phrase

Create a new seed phrase with 12, 15, 18, 21, or 24 words. SubWallet supports both standard and TON-specific seed phrases.
2

Select account types

Choose which blockchain account types to create from your seed phrase:
  • Substrate accounts (Polkadot, Kusama, and parachains)
  • Ethereum and EVM-compatible accounts
  • TON accounts
  • Cardano accounts
  • Bitcoin accounts
3

Set account name and password

Give your account a memorable name and set a master password to secure your wallet.
All accounts created from the same seed phrase are linked together in a unified account group, making it easy to manage multiple blockchain addresses.

​
Import Existing Account

Bring your existing blockchain accounts into SubWallet.
Import accounts by entering your existing 12-24 word seed phrase. SubWallet automatically detects the phrase type and shows you which account types can be created.

​
Connect Hardware Wallets

Connect your Ledger hardware wallet for maximum security.
1

Connect device

Plug in your Ledger device and unlock it with your PIN.
2

Select accounts

Choose which accounts to import from your Ledger. You can import multiple accounts at once.
3

Confirm import

SubWallet creates read-only accounts that require your Ledger device to sign transactions.
Ledger accounts require the physical device to be connected when signing transactions. Keep your Ledger firmware updated for the best compatibility.

​
Managing Accounts

​
Account Groups (Unified Accounts)

When you create multiple account types from the same seed phrase, they’re automatically grouped together. This makes it easy to:
  • Switch between different blockchain networks while staying in the same account
  • View all your assets across networks in one place
  • Manage related accounts as a single unit

​
Switching Accounts

Quickly switch between your accounts or view all accounts together:
  • Individual Account: View and manage a specific account
  • All Accounts: See combined balances and assets across all your accounts
  • Account Groups: Switch between unified multi-chain account groups

​
Renaming Accounts

Give your accounts descriptive names to stay organized:
  1. Select the account you want to rename
  2. Click the edit icon or settings
  3. Enter a new name
  4. Save your changes

​
Exporting Accounts

Back up your accounts for safekeeping:

Export Seed Phrase

Export your seed phrase to import the account into another wallet. Requires your password.

Export JSON

Export Substrate accounts as encrypted JSON files. Set a password when exporting.

Export Private Key

Export the private key for Ethereum/EVM accounts. Requires your password.

Export QR Code

Generate a QR code to import the account on another device.
Never share your seed phrase, private keys, or JSON file passwords. Anyone with access to these can control your accounts and assets.

​
Security Features

​
Master Password

Your master password encrypts all accounts stored in SubWallet. You’ll need it to:
  • Create or import new accounts
  • Export account credentials
  • Sign transactions
  • Access the wallet after locking
Choose a strong master password and store it securely. If you forget it, you’ll need your seed phrase or private keys to recover access.

​
Account Authorization

Control which websites can access your accounts:
  • Grant access to trusted dApps
  • Revoke access at any time
  • See which sites are connected to each account

​
Account Locking

Lock your wallet when not in use for added security. The extension automatically locks after a period of inactivity, which you can configure in settings.

​
Deriving Accounts

Create multiple accounts from a single seed phrase using derivation paths. This is useful for:
  • Creating separate accounts for different purposes
  • Generating additional addresses without a new seed phrase
  • Organizing accounts by use case (personal, business, testing)
Each derived account has a unique address but shares the same underlying seed phrase.

​
Best Practices

Write down your seed phrase and store it in a safe place offline. Never store it digitally or share it with anyone. This is the master key to all accounts derived from it.
Name your accounts clearly (e.g., “Main Wallet”, “Trading Account”, “DeFi Activities”) to avoid confusion when managing multiple accounts.
Periodically verify that you still have access to your seed phrase and backup files. Test your backups by importing them in a separate browser profile.
For significant holdings, consider using a Ledger hardware wallet for an extra layer of security.
