How Does Wrapped Bitcoin Work?

The process of wrapping Bitcoin involves a consortium of custodians who hold the Bitcoin assets and issue the equivalent amount of WBTC on the Ethereum network. These custodians are responsible for securely storing the Bitcoin and ensuring the 1:1 peg between WBTC and Bitcoin. Users who wish to obtain WBTC can do so by depositing their Bitcoin with one of the approved custodians and receiving the same value of WBTC tokens. Conversely, users who want to redeem their WBTC for Bitcoin can initiate the unwrapping process, where the WBTC tokens are burned, and the equivalent Bitcoin is released from the custodian’s reserves.

Who is Behind Wrapped Bitcoin?

Wrapped Bitcoin is a collaborative effort between various industry participants, including custodians, decentralized exchanges, and DeFi protocols. The custodians, such as BitGo and CoinList, hold the Bitcoin assets and issue the corresponding WBTC tokens. Crypto custodian BitGo plays a significant role in providing the necessary security infrastructure for the WBTC system. Other prominent players in the WBTC ecosystem include Kyber Network, Ren Protocol, and MakerDAO, which facilitate the trading and lending of WBTC on their platforms.

Getting Started with Wrapped Bitcoin

How to Wrap Bitcoin

To wrap Bitcoin and obtain WBTC, users need to choose a WBTC custodian that supports the wrapping process. After selecting a custodian, users deposit their Bitcoin with the custodian and receive the equivalent value in WBTC tokens. The custodian holds the Bitcoin securely in reserve, ensuring the 1:1 peg between WBTC and Bitcoin. This wrapped version of Bitcoin can then be transferred and utilized within the Ethereum ecosystem.

How to Unwrap Bitcoin

When users wish to redeem their WBTC for Bitcoin, they can initiate the unwrapping process with the custodian holding their WBTC. The custodian will burn the WBTC tokens, and upon verification, release the equivalent amount of Bitcoin back to the user’s wallet. This unwrapping process reaffirms the 1:1 peg between WBTC and Bitcoin, providing users with a seamless way to convert their tokenized Bitcoin back to the original asset.

Choosing a WBTC Provider

When choosing a WBTC provider, it is essential to consider factors such as custodial reputation, security measures, and the track record of successfully maintaining the 1:1 peg.
