How WBNB Wrapper works
Choose wrap or unwrap
Select BNB to WBNB to wrap, or WBNB to BNB to unwrap. Your available balance shows under the field, and Refresh Balances reads it again if coins have just arrived in your wallet.
What WBNB Wrapper does
In short
WBNB Wrapper is the simple way to wrap BNB to WBNB, or unwrap WBNB back to BNB, at an exact one-to-one rate. It is for traders, liquidity providers and builders who need the BEP-20 form of BNB for a pool, a contract or a swap that does not take native BNB.
What it does
Pick a direction and an amount, typed or filled with MAX. The page checks your BNB or WBNB balance first. Your wallet then signs two transactions: the J Tools fee payment and the conversion itself, a deposit into or a withdrawal from the official WBNB contract. The coins arrive as soon as it confirms.
What it costs
Each conversion costs a flat 0.00036 BNB, paid first in its own transaction. If the conversion then fails or you reject it, the fee stays on record as a credit and the next press asks only for the conversion. Gas is separate, paid in BNB, and your wallet shows the exact amount before you sign.
Key features
- Both directions · Wrap BNB into WBNB or unwrap WBNB into BNB from the same panel.
- Always one to one · One WBNB is always worth exactly one BNB, with no pool and no slippage.
- Official WBNB contract · Conversions go through the canonical WBNB contract that the PancakeSwap router uses.
- Smart MAX button · A wrap keeps back enough BNB to cover the fee and the gas.
- Fee kept as credit · A fee paid without a finished conversion covers the next conversion you make.
- Balance checks first · An unwrap larger than your WBNB balance is stopped before anything is signed.

What WBNB is on BNB Chain
WBNB is BNB wrapped as a BEP-20 token, the token standard of BNB Chain (also called BSC or BNB Smart Chain, chain ID 56). Native BNB pays for gas but does not follow the BEP-20 interface, so many contracts work with WBNB instead. PancakeSwap pools pair tokens against WBNB, and some protocols accept only the token version. The WBNB contract holds the BNB and issues exactly one WBNB for each BNB, so you can always swap back. You can follow every deposit and withdrawal on BscScan, under the WBNB contract or your own address.
