About this tool
How Gas Top-Up works
Choose the target balance
Pick one of the preset amounts or type your own. This is the BNB balance every wallet should end up with: a wallet below it gets the difference, and a wallet at or above it gets nothing.
What Gas Top-Up does
In short
Gas Top-Up is the quick way to send BNB to multiple wallets so each one can pay for its own gas. Set the balance every wallet should hold, paste up to 200 addresses, and each wallet below that level gets exactly what it is missing, all in one transaction from your own wallet.
What it does
The inputs are a target BNB balance, picked from presets or typed, and a list of wallets pasted or uploaded as CSV. The page reads every balance at one block and shows what each wallet gets. Your wallet then signs a single Multi Sender transaction that tops up every wallet that is short.
What it costs
J Tools charges 0.0005 BNB per wallet that actually receives BNB, the same price as Multi Sender, paid inside the same transaction. Wallets already at the target are skipped and cost nothing. Network gas is separate and paid in BNB. Your wallet shows the exact total, BNB sent plus fee, before you sign.
Key features
- Exact difference only · Each wallet gets what it is short of the target, never a fixed lump sum.
- One transaction · Up to 200 wallets are funded with a single signature through Multi Sender.
- Full wallets skipped · Wallets already holding the target or more get nothing and add no fee.
- Fresh balances before signing · Balances are read again before your wallet opens, and any change brings back new amounts.
- List clean-up · Bad lines, your own wallet and repeats are flagged and removed in one click.
- Test run first · A contract address that refuses BNB is caught before you sign, not after.

Check the table and top up
The table shows each balance and what it gets, and the summary shows the BNB sent and the fee. Press Top Up Wallets. Balances are read once more before your wallet opens, then you sign one transaction.
Why wallets need BNB for gas
Every transaction on BNB Chain, the network also known as BSC or BNB Smart Chain (chain ID 56), pays its gas in BNB. A wallet that holds only BEP-20 tokens cannot move them, swap on PancakeSwap or approve a contract until it has a little BNB. Gas Top-Up fills that gap for a whole set of wallets at once, which helps before a multi-wallet trading session or right after you create wallets in bulk. The single top-up transaction lists every transfer on BscScan, and Balance Checker can confirm the new balances afterwards.
