Avalanche C-Chain: wrap & unwrap AVAX

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

Switch network

What is WAVAX?

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

Why use this tool

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

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

When do I need WAVAX?

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