FAQ

During setup, Blast Mobile creates a new smart wallet for you, secured with passkey authentication.

Unlike externally owned accounts (EOAs), which are derived from a seed phrase and use a private key to sign transactions, smart wallets are deployed as smart contracts on the blockchain. Since smart wallets do not have private keys, they rely on an externally owned account (EOA) as a ‘signer’ to authorize transactions.

The seed phrase you can export from Blast Mobile belongs to this signer account, not the Blast Mobile smart wallet itself.

Blast Mobile uses passkey authentication, which requires your device to support passkey creation and backup.

• On iOS: Ensure that iCloud is enabled and that iCloud Keychain is set up to back up your passkeys securely.
• On Android: Confirm that your device is configured to use Google Password Manager for storing and managing passkeys.

See the FAQ section below on Passkey Authentiction for more info.

Your Blast Mobile wallets are linked to the passkey created during setup. As long as you retain access to your passkey, your wallets can be recovered. Passkeys are securely backed up to iCloud Keychain (for iOS) or Google Password Manager (for Android), allowing you to restore access on any device signed in with the same Apple or Google account.

Blast Mobile is designed to simplify and improve the user experience when interacting with dapps. Its smart wallets enable passkey authentication, eliminate the need to manage private keys, let us sponsor gas for your transactions, and allow seamless transactions without confirmations using Pro Mode.

To maintain these benefits, Blast Mobile does not currently support importing EOAs, as they can’t take full advantage of these features. However, we understand this may be a significant change from your previous experience and are exploring the possibility of enabling EOA imports in a future update.

Enabling Blast Mobile’s Pro Mode allows you to interact with trusted dapps in Blast Mobile without having to confirm/sign transactions for a smoother user experience.

Blast Mobile’s initial launch focuses on helping users get familiar with the platform and introducing our updated tokenomics through the Earn App.

We are actively working with dapps across the Blast ecosystem and will be rolling out their integrations on Blast Mobile soon. Stay tuned!

Yes! There have been no changes to Blast’s native yield. You will continue to earn yield on ETH, WETH, and USDB as before. Native yield is earned in the same currency as your balance—for example, ETH on your ETH balances and USDB on your USDB balances.

This differs from the Earn App, a new yield-earning opportunity launched with Blast Mobile. By depositing USDB into the Earn App, you can earn a significantly higher APY (50%+). However, yield from the Earn App is paid in BLAST.

See our Earn App Overview for step-by-step instructions on getting started.

In the Earn App, you earn yield only on your USDB deposits, but the yield is paid out in BLAST.

For example, if you earn $100 of yield on your USDB deposits, you would receive that yield as $100 worth of BLAST.

While your BLAST balance doesn’t earn yield in the Earn App, it does affect your multiplier, which can boost your earnings. Check related FAQs on maximizing your multiplier for more details.

You can withdraw your USDB and BLAST at any time. BLAST rewards earned through the Earn App are liquid and can be withdrawn / sold as soon as you’ve earned them.

Your multiplier starts at 1x and increases linearly to 6x based on the relative value (denominated in USD) of BLAST to USDB that you’ve deposited into the Earn App.

You will reach the maximum multiplier of 6x when your BLAST deposits are equivalent in value to 30% of your USDB deposits.

The amount of BLAST required to maximize your multiplier is relative to how much USD you’ve deposited into the Earn App.

To maximize your multiplier, your BLAST balance needs to be equivalent to 30% of the value of your USD deposit.

Your multiplier is based on the relative value of your BLAST and USDB balances, so it may fluctuate with changes in the price of BLAST.

• If the price of BLAST increases, your multiplier will increase because the ratio of BLAST value to USDB value becomes higher.
• Conversely, if the price of BLAST decreases, your multiplier will decrease.

A passkey is a secure, passwordless login method that lets you sign in using your device’s biometrics (like Face ID or a fingerprint). It’s easy to use, resistant to phishing, and your login information is safely stored on your device and backed up in iCloud or Google Password Manager for seamless access across devices.

No, Blast Mobile currently only supports:

• iOS Users: iCloud Keychain
• Android User: Google Password Manager
