Understanding WBTC
What is WBTC?
Wrapped Bitcoin is an ERC-20 token backed 1:1 by Bitcoin, allowing BTC to be used in Ethereum DeFi protocols.
Use Cases
DeFi Integration: Use WBTC in lending protocols, DEXs, yield farming, and other DeFi applications.
Network Options
Ethereum
- Pros: Largest DeFi ecosystem, highest liquidity
- Cons: Higher gas fees
- Best for: Large swaps, maximum DeFi compatibility
Arbitrum
- Pros: Lower fees, faster transactions
- Cons: Smaller ecosystem than Ethereum
- Best for: Smaller swaps, cost-efficient transactions
Important Notes
Exact Amounts: When sending Bitcoin manually, always send the exact amount shown. Sending more or less than the specified amount can cause delays or require manual intervention.
Security: Garden uses atomic swaps, meaning your Bitcoin is never at risk. If the swap fails, your BTC will be automatically refunded to your specified address.
First-Time Users: The first transaction may take slightly longer due to blockchain confirmations. Subsequent swaps in the same session are faster.
Next Steps
After receiving your WBTC:- Ethereum WBTC: Can be used immediately in Ethereum DeFi protocols
- Arbitrum WBTC: Can be used in Arbitrum DeFi protocols or bridged to other networks
- Track Your Assets: WBTC will appear in your EVM wallet on the selected network
