X Layer: wrap & unwrap OKB

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

Switch network

What is WOKB?

WOKB is OKB 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 WOKB. The WOKB contract holds every deposited OKB and mints exactly the same amount of WOKB; unwrapping burns it and returns the OKB. Nothing else is involved — no price, no slippage, no counterparty.

Why use this tool

  • Canonical contracts only — the same WOKB address that DEX routers use, verified on-chain.
  • Every transaction is simulated first; the network fee is shown before you sign.
  • “Max” keeps enough OKB 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 OKB?

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

When do I need WOKB?

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