MetaMask has established itself as the go-to Ethereum wallet for interacting with decentralized applications (dApps). But can this popular wallet support Bitcoin (BTC), the world's premier cryptocurrency? The answer lies in wrapped Bitcoin (wBTC) - an ERC-20 token that represents Bitcoin on the Ethereum blockchain.
Understanding MetaMask's Cryptocurrency Support
MetaMask's Native Compatibility
MetaMask exclusively supports:
- Ethereum (ETH)
- ERC-20 tokens
- ERC-721 tokens (NFTs)
As Bitcoin operates on its own blockchain, native BTC cannot be stored directly in MetaMask. Attempting to send Bitcoin to a MetaMask address will result in permanent loss of funds.
The wBTC Solution
Wrapped Bitcoin (wBTC) solves this incompatibility by:
- Locking BTC on the Bitcoin blockchain
- Minting equivalent ERC-20 tokens on Ethereum
- Maintaining 1:1 peg with real Bitcoin

Step-by-Step: Converting BTC to wBTC for MetaMask Storage
1. Acquiring wBTC Through Exchanges
Most major exchanges offer BTC/wBTC trading pairs:
| Exchange | Trading Pair | Minimum Order |
|---|---|---|
| Binance | BTC/wBTC | 0.001 BTC |
| Coinbase | BTC/wBTC | 0.01 BTC |
| Kraken | BTC/wBTC | 0.0001 BTC |
2. Transferring wBTC to MetaMask
- Copy your MetaMask Ethereum address
- Withdraw wBTC from exchange to this address
- Wait for Ethereum network confirmation (~2-5 minutes)
3. Adding wBTC to MetaMask Display
If wBTC doesn't appear automatically:
- Click "Import tokens"
- Enter wBTC contract address:
0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 - Confirm token addition
Security Considerations for wBTC Storage
Hardware Wallet Integration
While MetaMask is a hot wallet, you can enhance security by:
- Connecting Ledger/Trezor devices
- Enabling transaction confirmations on hardware
- Keeping recovery phrases offline

- Verify official contract addresses
- Beware of fake wBTC tokens
- Only use audited bridges like BitGo (wBTC issuer)
