Convert your native Bitcoin to Wrapped Bitcoin (WBTC) on Ethereum or Arbitrum networks. WBTC maintains a 1:1 peg with Bitcoin and can be used in DeFi protocols. The flow is same for BTC to any EVM based asset.
This guide covers swapping Bitcoin (BTC) to Wrapped Bitcoin (WBTC) on Ethereum or Arbitrum. The process takes approximately 30 seconds to complete.

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
