WBTC (Wrapped Bitcoin) is an Ethereum-based token pegged 1:1 to Bitcoin. It enables Bitcoin holders to participate in Ethereum's DeFi ecosystem by locking BTC in a smart contract and minting equivalent WBTC tokens.
Key Benefits of WBTC
- Ethereum Compatibility: Use Bitcoin in Ethereum-based apps (e.g., decentralized exchanges, lending protocols).
- Smart Contract Utility: Enables BTC collateralization in DeFi without selling Bitcoin.
- DAO Governance: Managed by the WBTC DAO, a consortium including BitGo, Uniswap, and Kyber Network.

Understanding WBTC Bridges
A WBTC bridge facilitates token transfers between Ethereum and other blockchains (e.g., BNB Chain, Polygon). Unlike wrapping BTC into WBTC (which involves smart contracts), bridging moves WBTC across chains for broader DeFi access.
How to Bridge WBTC via ChainPort
Step 1: Connect Your Wallet
- Visit ChainPort’s dApp.
- Link supported wallets (MetaMask, Ledger, Coinbase Wallet, etc.).
Step 2: Select Networks & Token
- Source Chain: Ethereum (or current WBTC network).
- Target Chain: Choose from Arbitrum, Polygon, Avalanche, etc.
- Token: Select WBTC.
Step 3: Confirm Transaction
Review gas fees and details, then approve. Tokens arrive on the target chain in minutes.

FAQs
Q: Is bridging WBTC the same as wrapping Bitcoin?
A: No. Wrapping converts BTC to WBTC on Ethereum; bridging moves WBTC across chains.
Q: What wallets work with ChainPort?
A: MetaMask, Ledger, Trezor, WalletConnect, and Coinbase Wallet.
Q: Are there fees for bridging WBTC?
A: Yes—gas fees vary by network congestion and target chain.
Q: How long does bridging take?
A: Typically 2–10 minutes, depending on the blockchain.
