BNB Smart Chain: wrap & unwrap BNB

Convert BNB ⇄ WBNB 1:1 with the official WBNB contract. Use your connected wallet or process a whole list of wallets in one run.

What is WBNB?

WBNB is BNB packaged as a standard token. DEX pools, lending markets, NFT marketplaces and many smart contracts can only handle tokens, not the native coin, so they use WBNB. The WBNB contract holds every deposited BNB and mints exactly the same amount of WBNB; unwrapping burns it and returns the BNB. Nothing else is involved — no price, no slippage, no counterparty.

Why use this tool

  • Canonical contracts only — the same WBNB address that DEX routers use, verified on-chain.
  • Every transaction is simulated first; the network fee is shown before you sign.
  • “Max” keeps enough BNB for gas, so a wallet is never left unable to move.
  • Bulk mode: wrap or unwrap in many wallets at once (entire balance, a percentage or a fixed amount), keys never leave your browser.
  • No service fee — only network gas.

FAQ

Does wrapping change the value of my BNB?

No. 1 BNB = 1 WBNB, always. The contract holds the BNB and gives it back 1:1 when you unwrap.

When do I need WBNB?

When a protocol works only with tokens: adding liquidity, some DEX trades, lending, NFT bids or a bot that trades WBNB pairs.

How much does it cost?

Only the network fee of one contract call. ChainTx charges nothing for wrapping or unwrapping.

Is bulk mode safe?

Private keys are processed only in your browser tab to sign each wallet’s own transaction and are never sent to our servers. For everyday use, the connected-wallet mode needs no keys at all.
