Introduction
Wrapped Bitcoin (WBTC) bridges the gap between Bitcoin and the Ethereum blockchain.
It represents Bitcoin as an ERC-20 token, enabling BTC holders to access Ethereum-based decentralized finance (DeFi) applications and services.
What is Wrapped Bitcoin?
Wrapped Bitcoin (WBTC) is an ERC-20 token on the Ethereum blockchain that is fully backed by Bitcoin at a 1:1 ratio.
Each WBTC token is minted or burned when Bitcoin is deposited or withdrawn through trusted custodians.
This tokenized form of Bitcoin allows users to use BTC in Ethereum’s ecosystem while maintaining its value.
The History of Wrapped Bitcoin
Wrapped Bitcoin was launched in January 2019 as a collaborative effort between multiple organizations, including BitGo, Kyber Network, and Ren.
The initiative aimed to combine Bitcoin’s liquidity with Ethereum’s programmability.
Since its inception, WBTC has gained significant adoption, becoming a leading asset in DeFi.
How Does Wrapped Bitcoin Work?
Minting and Burning:
When a user wants WBTC, Bitcoin is sent to a custodian who mints an equivalent amount of WBTC.
To redeem Bitcoin, the WBTC is burned, and the Bitcoin is returned to the user.
Trust and Transparency:
Custodians ensure that all minted WBTC are backed 1:1 by Bitcoin.
On-chain audits allow users to verify reserves.
Why is Wrapped Bitcoin Important?
Liquidity: WBTC brings Bitcoin’s immense liquidity into Ethereum’s DeFi ecosystem, enabling seamless BTC-based trading, lending, and borrowing.
Interoperability: It connects the Bitcoin and Ethereum blockchains, broadening use cases for BTC holders.
DeFi Integration: WBTC allows BTC to be utilized in Ethereum-based DeFi protocols, such as yield farming, lending, and staking.
Risks and Considerations
Centralization: WBTC relies on custodians for minting and burning, introducing trust requirements.
Smart Contract Risks: Since WBTC operates on Ethereum, it is subject to vulnerabilities in the smart contracts managing it.
How to Use Wrapped Bitcoin
DeFi Platforms: Use WBTC to participate in decentralized lending, yield farming, and liquidity pools.
Trading: Trade WBTC against other tokens on decentralized exchanges like Uniswap.
Collateral: Use WBTC as collateral for loans in DeFi protocols.

Conclusion
Wrapped Bitcoin (WBTC) provides a unique solution for integrating Bitcoin into the Ethereum ecosystem, unlocking new opportunities for BTC holders.
While it brings significant advantages like liquidity and interoperability, users should remain cautious about its centralized aspects and associated risks.
