Ethereum and Avalanche are two leading blockchain networks that utilize the Proof of Stake (PoS) consensus mechanism. Both platforms support smart contracts and host a vibrant DeFi ecosystem with numerous decentralized applications (DApps) and tokens.
To transfer assets between these blockchains, you’ll need a cross-chain bridge—a protocol enabling seamless crypto transfers across different networks with minimal fees.
This guide walks you through bridging assets from Ethereum to Avalanche step by step, using the Avalanche Core Bridge.
Quick Steps To Bridge ETH to AVAX
- Fund your MetaMask wallet with ETH.
- Add Avalanche Network to MetaMask (or use a wallet with built-in Avalanche support).
- Visit Core.app (Avalanche Bridge).
- Click [Connect Wallet] and approve the connection.
- Select the token and amount to bridge.
- Click [Bridge Tokens] and confirm the transaction.
- Swap WETH.e for AVAX on a decentralized exchange (e.g., GMX).

Step-by-Step Guide
Step 1: Fund Your MetaMask Wallet with ETH
- Purchase ETH on a centralized exchange (e.g., Binance).
- Transfer ETH to your MetaMask Ethereum wallet address.
Step 2: Add Avalanche Network to MetaMask
- Go to ChainList.
- Search for Avalanche C-Chain and click [Add to MetaMask].
- Approve the network addition.
Non-MetaMask users can skip this step if their wallet already supports Avalanche.
Step 3: Connect Wallet to Avalanche Core Bridge
- Visit Core.app/bridge.
- Click [Connect Wallet] and select your wallet (e.g., MetaMask, Coinbase Wallet).
- Approve the connection request.
Step 4: Select Token and Bridge
- Choose a token (e.g., ETH, USDT, USDC).
- Enter the amount and click [Bridge Tokens].
- Confirm the transaction and pay the bridge fee ($3 in ERC-20 tokens).
Step 5: Swap WETH.e for AVAX
- Visit GMX Exchange.
- Switch to Avalanche Network.
- Connect your wallet and select WETH.e → AVAX.
- Enter the amount and click [Swap].
Costs of Bridging ETH to AVAX
- Exchange withdrawal fee (varies by platform).
- Bridge fee: $3 in ERC-20 tokens.
- Swap fee: ~0.23% on GMX.
