What is WBTC and how does Wrapped Bitcoin work?

Hi everyone, I'm Mike! In the world of cryptocurrency, you've probably heard of WBTC, or Wrapped Bitcoin, an innovative asset that combines Bitcoin with an ethereum chain, allowing Bitcoin to be used in the DeFi ecosystem for greater value. This article will take you on a deeper dive into the features and technology of WBTC, including how it's implemented, what application scenarios it has, and how it can help you better participate in rebates and earn passive income on trading platforms like Ouyi. If you're interested in cryptocurrencies and decentralized finance, let's explore together!

What is WBTC?

The full name of WBTC is Wrapped Bitcoin. It is an ERC-20 token that represents a 1:1 bitcoin reserve. This means that each WBTC is backed by a real Bitcoin, ensuring that the value of the token is kept in sync with Bitcoin.
WBTC was created to solve the problem of Bitcoin's inability to participate directly in the Ether ecosystem. As an ERC-20 token, WBTC can be used for various applications in Decentralized Finance (DeFi), such as lending, trading, and revenue farming. This not only enhances the liquidity of Bitcoin, but also gives holders more opportunities to participate in more efficient asset utilization.

Technical Basis of WBTC

How to realize 1:1 chain mapping
WBTC is operated by a multi-party governance organization (e.g. BitGo, Kyber Network, etc.). Every time a WBTC is created or destroyed, it is subject to a smart contract and reserve audit to ensure that each WBTC has a corresponding Bitcoin deposit in a third-party escrow account.

The Role of Smart Contracts
The generation and destruction of WBTC is done entirely through smart contracts, which are transparent and automated, avoiding the risk of human intervention. These smart contracts are open source and anyone can view the code, increasing the level of trust.

WBTC Functions and Applications

Enhancing Bitcoin's Liquidity
Bitcoin is the largest cryptocurrency by market capitalization, but its liquidity is confined to its own blockchain. wBTC brings it into the ethereum ecosystem with the ability to participate in trading pools on decentralized exchanges (DEXs), increasing the efficiency of asset liquidity.

Participate in the DeFi application
With WBTC, users can use it to borrow, pledge, or participate in revenue farms, operations that are not possible on the native Bitcoin chain. For example, you can use WBTC as collateral for a stablecoin loan on a DeFi platform like Aave.

Rebates and Arbitrage
On platforms like Ouyi, users are able to take advantage of WBTC's price volatility to arbitrage their trades and even combine them with rebate strategies to further increase their earnings.

Strengths and Challenges of WBTC

Key Benefits

1. high clarity: The reserves are managed by a trustworthy custodian and are audited and published on a regular basis.
2. Mobility Enhancement: Breaking through the blockchain limitations of Bitcoin and allowing more money to flow into the DeFi ecosystem.
3. Easy to integrate: Based on the ERC-20 standard, it is highly compatible with Ethernet applications.

Potential Challenges

1. Centralized Risk: Although smart contracts are transparent, custodians still have to bear the trust issue.
2. Handling Fee Costs: Converting Bitcoin to WBTC involves multiple layers of fees and may increase transaction costs.
3. Risk of market volatilityWBTC: Although WBTC is linked to the value of Bitcoin, market sentiment still affects its practical application and value.

How do I purchase and use WBTC?

Purchasing a WBTC is very simple and you can do it by following these steps:

1. Select an exchange that supports WBTC
   For example, at Ouyi, you can buy WBTC directly in BTC or stablecoins.
2. Convert BTC to WBTC
   On the exchange, select the "Parcel" option and enter the corresponding amount of BTC to receive the equivalent in WBTC.
3. Using WBTC
   You can transfer it to an Ether Wallet to pledge, borrow, or participate in other applications on the DeFi platform.

Frequently Asked Questions Q&A

1. Is WBTC's handling fee high?
Compared to using BTC directly, WBTC transactions involve a GAS fee on Ether, the cost of which depends on the current network congestion.

2. Is WBTC fully decentralized?
Although smart contracts are decentralized, WBTC's reserve custody involves centralized institutions, so it is a combination of centralization and decentralization.

3. Are there risks associated with using WBTC?
Key risks include smart contract vulnerabilities, custodian risks, and systemic risks to the Ethernet network itself.
