Gnosis: wrap & unwrap xDAI
Convert xDAI ⇄ WXDAI 1:1 with the official WXDAI contract. Use your connected wallet or process a whole list of wallets in one run.
What is WXDAI?
WXDAI is xDAI 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 WXDAI. The WXDAI contract holds every deposited xDAI and mints exactly the same amount of WXDAI; unwrapping burns it and returns the xDAI. Nothing else is involved — no price, no slippage, no counterparty.
Why use this tool
- Canonical contracts only — the same WXDAI address that DEX routers use, verified on-chain.
- Every transaction is simulated first; the network fee is shown before you sign.
- “Max” keeps enough xDAI 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 xDAI?
No. 1 xDAI = 1 WXDAI, always. The contract holds the xDAI and gives it back 1:1 when you unwrap.
When do I need WXDAI?
When a protocol works only with tokens: adding liquidity, some DEX trades, lending, NFT bids or a bot that trades WXDAI 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.
