In the rapidly evolving world of cryptocurrency, understanding how to add bitcoin to MetaMask is a crucial skill for both new and experienced users. While MetaMask is primarily built for Ethereum and ERC-20 tokens, you can still store bitcoin indirectly through a tokenized version known as Wrapped Bitcoin (WBTC). This guide walks you through every step—from setting up your wallet to securely managing and using your BTC-backed assets in decentralized finance (DeFi).
What Is MetaMask?
A Gateway to Decentralized Finance
MetaMask is more than just a digital wallet—it’s a powerful interface that allows users to interact with blockchains, manage assets, and access decentralized applications (dApps). With over 30 million users worldwide, it has become one of the most trusted tools in the crypto space.
Available as a browser extension and mobile app, MetaMask securely stores your private keys and enables seamless transactions across Ethereum-compatible networks.

Does MetaMask Support Bitcoin?
No—MetaMask does not support native BTC on the Bitcoin blockchain. However, you can use WBTC (Wrapped Bitcoin), an ERC-20 token pegged 1:1 to real Bitcoin, to bring BTC value into the Ethereum ecosystem.
This means you can store BTC value in MetaMask by converting your bitcoin into WBTC, opening the door to lending, staking, and trading within DeFi platforms.
Understanding BTC vs. WBTC
Bitcoin (BTC): Digital Gold
Bitcoin remains the original cryptocurrency, operating on its own blockchain using Proof of Work. It's widely used as a store of value and medium of exchange, with transactions verified and recorded on the Bitcoin network.
Wrapped Bitcoin (WBTC): Bridging Blockchains
WBTC is an Ethereum-based token that represents Bitcoin. Each WBTC is backed by exactly 1 BTC held in reserve by trusted custodians. This "wrapping" process locks BTC and mints an equivalent amount of WBTC on Ethereum.
As an ERC-20 token, WBTC can be used across Ethereum dApps, making it ideal for integration with MetaMask.
Key Differences Between BTC and WBTC
| Feature | BTC | WBTC |
|---|---|---|
| Blockchain | Bitcoin | Ethereum |
| Token Standard | N/A | ERC-20 |
| Use Case | Peer-to-peer payments, store of value | DeFi participation, yield farming |
| Transaction Speed | Slower (10+ minutes) | Faster (seconds to minutes) |
WBTC allows you to hold and use bitcoin in decentralized finance while benefiting from Ethereum’s smart contract capabilities.
How to Add WBTC to MetaMask: Step-by-Step
Step 1: Set Up Your MetaMask Wallet
If you haven’t already:
- Download the official MetaMask extension or app.
- Create a new wallet.
- Securely back up your 12-word recovery phrase—never share it or store it digitally.
Ensure your wallet is connected to the Ethereum Mainnet, as WBTC operates on this network.
Step 2: Buy WBTC
You can acquire WBTC through:
- Centralized exchanges like Binance, Coinbase, or Kraken
- Direct swaps using DeFi protocols like Uniswap or SushiSwap
- Hardware wallets like Ledger (when linked to MetaMask)
When purchasing, ensure you're buying actual WBTC—not similar-sounding tokens.

Step 3: Send WBTC to MetaMask
- Open MetaMask and copy your Ethereum address.
- On your exchange or wallet, initiate a WBTC withdrawal.
- Paste your MetaMask address as the destination.
- Confirm the transaction and pay gas fees in ETH.
⚠️ Always double-check addresses. Crypto transactions are irreversible.
Step 4: Add WBTC as a Custom Token
WBTC may not appear automatically. To manually add it:
- In MetaMask, click “Import Tokens.”
- Go to the “Custom Token” tab.
- Enter the WBTC contract address:
0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 - Confirm—WBTC should now show in your balance.
Using WBTC in DeFi Through MetaMask
Once WBTC is in your wallet, you can:
- Lend it on Aave or Compound to earn interest
- Swap it on Uniswap or Curve
- Provide liquidity in pools
- Use it as collateral for loans
This transforms your static bitcoin holdings into productive assets—without selling your BTC.
Security Best Practices for Storing WBTC
Protect Your Wallet
Since MetaMask is a self-custodial wallet, you are responsible for security. Follow these tips:
- Use a strong, unique password
- Enable two-factor authentication (2FA) on associated accounts
- Never share your seed phrase
- Beware of phishing sites and fake extensions
Consider a Hardware Wallet
For maximum security, connect MetaMask to a hardware wallet like Ledger or Trezor. This keeps your private keys offline while still allowing interaction with dApps.
Regular Backups
Store your recovery phrase offline—on paper or metal. Losing it means losing access to all assets permanently.
Withdrawing BTC from MetaMask
To get back native Bitcoin:
- Convert WBTC to BTC: Use a decentralized exchange (e.g., Uniswap + a cross-chain bridge) or centralized platform.
- Send BTC to external wallet: Transfer to a Bitcoin-compatible wallet where you control the keys.
- Verify the transaction: Track it via Blockchain.com or BTC.com using the transaction ID.
Note: Gas fees apply during conversion and transfer. Always check network conditions before initiating transactions.
Frequently Asked Questions (FAQ)
Can I store real Bitcoin directly in MetaMask?
No. MetaMask doesn’t support the Bitcoin blockchain natively. You must convert BTC to WBTC, an ERC-20 token, to store it in MetaMask.
Is WBTC safe?
Yes—WBTC is backed 1:1 by real Bitcoin held in custody. However, it relies on centralized custodians and oracles, introducing counterparty risk not present with native BTC.
What other tokens can I store in MetaMask?
MetaMask supports all ERC-20 and ERC-721 tokens (like USDT, DAI, UNI, NFTs), plus assets on EVM-compatible chains such as BSC, Polygon, and Avalanche when properly configured.
Can I send WBTC to a Bitcoin address?
No. WBTC exists only on Ethereum. Sending it to a Bitcoin address will result in permanent loss.
How do I check my WBTC balance?
Open MetaMask and look for WBTC in your asset list. For verification, paste your wallet address into Etherscan.io—no other links needed.
Is MetaMask free to use?
Yes—MetaMask is free to download and use. However, every transaction requires gas fees paid in ETH to process on the Ethereum network.
Final Thoughts
While you can’t store native bitcoin directly in MetaMask, using Wrapped Bitcoin (WBTC) gives you full access to BTC’s value within the Ethereum ecosystem. From secure storage to active participation in DeFi, this method empowers users to do more with their digital assets.
By following best practices for security and staying informed about blockchain interoperability, you can confidently store bitcoin via WBTC and explore the future of decentralized finance—all from your MetaMask wallet.
