What Is Ethereum kBTC?
Ethereum kBTC (Kintsugi Bitcoin) is a wrapped Bitcoin token that bridges Bitcoin’s liquidity to the Ethereum ecosystem. Unlike traditional Bitcoin, kBTC operates as an ERC-20 token, enabling seamless integration with Ethereum-based decentralized applications (dApps), decentralized exchanges (DEXs), and DeFi protocols. This cross-chain solution allows Bitcoin holders to participate in Ethereum’s vibrant ecosystem without selling their BTC.
How Does Ethereum kBTC Work?
kBTC is created through a trustless, decentralized bridge that locks Bitcoin in a secure vault and mints an equivalent amount of kBTC on Ethereum. Here’s the process:
- Locking BTC: Users send Bitcoin to a multi-signature vault.
- Minting kBTC: The bridge issues kBTC tokens on Ethereum at a 1:1 ratio.
- Using kBTC: Holders leverage kBTC in DeFi apps for lending, staking, or trading.
- Redeeming BTC: Users burn kBTC to unlock their original BTC.
Benefits of Ethereum kBTC
- DeFi Participation: Earn yield on Bitcoin via Ethereum’s lending platforms like Aave or Compound.
- Cross-Chain Liquidity: Trade kBTC for ETH or stablecoins on Uniswap or SushiSwap.
- Lower Fees: Avoid Bitcoin’s slower transactions by using Ethereum Layer 2 solutions.
- Interoperability: Use kBTC as collateral for loans or in NFT marketplaces.

Risks to Consider
