What is Wrapped Bitcoin (WBTC)?42

Wrapped Bitcoin (WBTC) is an ERC-20 token that represents Bitcoin (BTC) on the Ethereum blockchain. It was created to bridge the gap between the two most popular blockchains in the world, allowing users to trade, lend, and borrow Bitcoin on Ethereum's fast and scalable network.

WBTC is a fully collateralized token, meaning that there is always an equivalent amount of Bitcoin held in reserve to back the WBTC in circulation. The reserves are held by a group of custodians, including BitGo, Coinbase, and Gemini. This ensures that the value of WBTC is always linked to the value of Bitcoin.

WBTC was created by a consortium of companies including BitGo, Kyber Network, and Ren. It was launched in January 2019 and has quickly become one of the most popular ways to use Bitcoin on Ethereum.

How Does WBTC Work?

WBTC works by using a process called tokenization. Tokenization is the process of converting a real-world asset into a digital token that can be traded on a blockchain. In the case of WBTC, the real-world asset is Bitcoin and the digital token is WBTC.

When you want to create WBTC, you must first send an equivalent amount of Bitcoin to a custodian. The custodian will then mint an equivalent amount of WBTC and send it to your Ethereum address.

When you want to redeem WBTC for Bitcoin, you must send your WBTC to a custodian. The custodian will then burn your WBTC and send you an equivalent amount of Bitcoin.

Benefits of WBTC

There are several benefits to using WBTC, including:
Access to Ethereum's ecosystem: WBTC allows users to access the Ethereum ecosystem, which includes a wide range of decentralized applications (dApps), lending platforms, and exchanges.
Increased liquidity: WBTC increases the liquidity of Bitcoin by allowing it to be traded on Ethereum. This makes it easier for users to buy and sell Bitcoin.
Faster transactions: WBTC transactions are processed much faster than Bitcoin transactions. This is because Ethereum is a faster blockchain than Bitcoin.
Lower fees: WBTC transactions have lower fees than Bitcoin transactions. This is because Ethereum's gas fees are lower than Bitcoin's transaction fees.

Risks of WBTC

There are also some risks to consider when using WBTC, including:
Counterparty risk: WBTC is a custodial token, meaning that you must trust the custodians to hold your Bitcoin safely. If a custodian is hacked or goes bankrupt, you could lose your WBTC.
Smart contract risk: WBTC uses a smart contract to manage the minting and redemption of tokens. If the smart contract is hacked or has a bug, it could cause you to lose your WBTC.
Price volatility: The price of Bitcoin is volatile, which means that the price of WBTC can also be volatile. This could lead to losses if the price of Bitcoin falls.

Is WBTC Right for You?

WBTC is a good option for users who want to access the Ethereum ecosystem with Bitcoin. It is also a good option for users who want to increase the liquidity of their Bitcoin or who want to take advantage of the faster transactions and lower fees on Ethereum.

However, users should be aware of the risks involved in using WBTC before they invest. These risks include counterparty risk, smart contract risk, and price volatility.
