How to Use Power Bank

Power Bank is a balance that covers network fees when you don't have enough of the token a blockchain requires. Instead of buying ETH just to move your USDT, you pay the fee from your Power Bank.

How Power Bank Works

Every blockchain charges a network fee in its own native token — ETH on Ethereum, SOL on Solana, TRX on TRON. If you try to send an asset without holding that token, the transaction cannot go through. Power Bank solves this:

  • You top up Power Bank with crypto or by card — the balance is held in USD.

  • When a transaction needs a fee token you don't hold, Bron sends that network's native token to your account.

  • The cost is deducted from your Power Bank balance.

Power Bank always delivers the native gas token of the network your transaction is on, and works on supported networks only. If a network isn't supported yet, you still need to hold its native token to pay the fee.

⚠️ Using Power Bank includes two network fees: one for Bron to send you the required token, and one for the transaction you're making.

Where to Find Power Bank

Power Bank lives inside the send window:

  1. Click Transfer in the sidebar.

  2. Click the lightning badge with your balance in the top-right corner of the window.

The Power Bank panel opens, showing your current balance, a top-up button, and your activity.

How to Top Up Power Bank

In the Power Bank panel, click Top up Power Bank and choose how you want to pay: by card or with crypto.

By Card

  1. Select the Card tab.

  2. Enter an amount or pick one of the presets.

  3. Click Create payment link and complete the payment with your card.

With Crypto

  1. Select the Crypto tab.

  2. Choose the account to pay from.

  3. Select an asset and enter the amount.

  4. Review the network fee and the total, then click Preview and confirm.

💡 You can top up with major tokens such as ETH, SOL, USDC, USDT and BTC. The up-to-date list is always shown under Which tokens can I use to top up? in the top-up screen.
