How to Manage Your Wallet in OneKey App

OneKey App provides a unified multi-chain wallet management interface, letting you create, import, and switch between wallets on different blockchains — all within a single application, without constantly jumping between apps.

Why It Matters

As the blockchain ecosystem continues to expand, users often hold assets across multiple chains — Bitcoin, Ethereum, Solana, and more. Managing them with separate, independent wallets is not only confusing but also increases the risk surface for seed phrase exposure and phishing attacks. Centralizing wallet management reduces operational complexity and provides a clearer, complete view of your total asset picture.

The Ethereum Foundation's wallet guide also notes that choosing a secure, feature-rich wallet is a foundational step for participating in on-chain activities.

Core Mechanisms

Unified Multi-Chain Management

OneKey App supports deriving addresses for multiple chains from a single seed phrase — including Bitcoin (BTC), Ethereum (ETH), BNB Chain, Solana, Tron, and many EVM-compatible networks. One set of seed phrases manages multi-chain accounts, greatly simplifying the backup process.

Hardware Wallet Integration

If you use a OneKey hardware wallet, you can pair it with the App via Bluetooth or USB. This keeps private keys offline at all times, with signing performed on the hardware device — effectively isolating network attack risks.

Multiple Accounts and Wallets

The App supports creating or importing multiple independent wallets on the same device. You can assign custom names and avatars to each wallet for easy differentiation between personal accounts, team accounts, or wallets serving different purposes.

Address Book and Contacts

Frequently used receiving addresses can be saved to the address book. On your next transfer, simply select from the list rather than typing manually — reducing the risk of address entry errors.

User Scenarios

• New user creating a wallet: On first use, follow the guided setup to create a wallet and back up your seed phrase — you can have a multi-chain address ready within minutes.
• Existing user migration: Users with an existing seed phrase or private key can import directly into OneKey App. Assets are not moved; only the management interface changes.
• Hardware wallet users: Pair your OneKey hardware wallet with the App to check balances and market data daily in the App, then confirm signatures on the device when needed — balancing convenience and security.
• Team multi-sig management: Supports connecting multi-signature contract wallets, ideal for teams or DAOs that require multiple approvals before moving assets.

How to Access in OneKey App

1. Visit the OneKey download page and install the version for your device (iOS, Android, macOS, Windows, or Linux).
2. Open the App and choose "Create New Wallet" or "Import Existing Wallet."
   • Create new wallet: The App generates a 12- or 24-word seed phrase. Write it down offline immediately and store it safely — never take a screenshot or save it to the cloud.
   • Import existing wallet: Enter your seed phrase, private key, or connect a hardware device to complete the import.
3. Once your wallet is set up, the home screen shows all activated chain addresses and balances.
4. Tap the account icon in the top-right corner to switch wallets, or use "Wallet Management" to add a new account.
5. To manage token approvals, check authorized contracts in Settings and periodically audit them using tools like Revoke.cash.

Risks and Considerations

• Your seed phrase is the only recovery credential: OneKey does not store your seed phrase. If it is lost, assets in the wallet cannot be recovered. Back it up offline in multiple secure locations.
• Guard against phishing attacks: Always download the App from the OneKey official website or official app stores. Be alert to counterfeit websites and apps. Refer to OWASP Phishing Prevention to learn about common tactics.
• Token approval risk: When interacting with DeFi protocols, approvals grant contracts permission to spend specific tokens. Regularly check and revoke unused approvals on Revoke.cash to reduce the risk of losses from contract vulnerabilities. For more DeFi security knowledge, see the Ethereum DeFi page.
• Public network risk: Avoid performing wallet operations or signing transactions on public Wi-Fi. Use private networks whenever possible.
• Device security: Set a lock screen password on your phone and enable biometric or PIN protection within the App to prevent unauthorized access if your device is lost.

FAQ

Q: Is OneKey App open source? A: OneKey's core code is open-sourced on GitHub, allowing developers and security researchers to audit the logic, increasing transparency and trustworthiness. Visit the OneKey website for open-source details.

Q: Can one seed phrase manage multiple chains? A: Yes. OneKey App supports deriving BTC, ETH, SOL, and other multi-chain addresses from the same seed phrase, following widely used derivation standards like BIP-44.

Q: Does importing a wallet affect existing assets? A: No. The import operation simply establishes access to an existing address within the App. On-chain assets do not move, and your original wallet application continues to work normally.

Q: How do I confirm that a receiving address is mine? A: Tap the address for the relevant network in the App and select "Verify Address." If a hardware wallet is paired, the device screen will display the address for you to confirm visually.

Q: How do I recover my wallet after losing or replacing my phone? A: Reinstall OneKey App, choose "Import Wallet," and enter your backed-up seed phrase to restore access to all associated addresses and assets.
