Wrapped Bitcoin (WBTC)

Bridging Blockchains

Wrapped Bitcoin allows Bitcoin to be used on other blockchains like Ethereum by creating a token that represents Bitcoin on these networks. This lets Bitcoin holders interact with decentralized finance (DeFi) apps, decentralized exchanges (DEXs), and other smart contract platforms that Bitcoin’s own blockchain cannot support.

Decentralized Finance (DeFi)

Wrapped Bitcoin is widely used in DeFi for lending, borrowing, and collateral. Users can lock Wrapped Bitcoin into smart contracts to get loans or earn interest. It brings Bitcoin’s liquidity into Ethereum’s DeFi ecosystem, enabling more financial products and services.

Trading and Liquidity

Wrapped Bitcoin can be traded faster and cheaper on Ethereum-based platforms compared to native Bitcoin transactions. It also provides liquidity for DeFi protocols, making it easier to swap between Bitcoin and other tokens.

Margin Trading and Yield Farming

Users can use Wrapped Bitcoin for margin trading, allowing them to profit from price changes by going long or short. It can also be deposited in liquidity pools to earn rewards or fees.

Cross-Chain Interoperability

Wrapped Bitcoin enables Bitcoin holders to move their assets across different blockchains without selling their Bitcoin. This interoperability expands the use cases and access to various blockchain ecosystems.

Compatibility and Convenience

As an ERC-20 token, Wrapped Bitcoin is compatible with most Ethereum wallets and DeFi apps, making it easy to transfer, trade, and use in decentralized applications.

In summary, Wrapped Bitcoin brings Bitcoin’s value and liquidity into Ethereum’s smart contract world, unlocking new financial opportunities and faster, more flexible use of Bitcoin across blockchain ecosystems.

Advantages of Wrapped Bitcoin

• Wrapped Bitcoin (WBTC) is pegged 1:1 to Bitcoin, allowing holders to maintain Bitcoin's value while using it on the Ethereum blockchain.
• It enables Bitcoin holders to participate in decentralized finance (DeFi) applications such as lending, borrowing, and trading on decentralized exchanges.
• Transactions with Wrapped Bitcoin on Ethereum are faster and usually cost less than on the Bitcoin network.
• WBTC increases liquidity and usability of Bitcoin by bridging it to Ethereum’s smart contract ecosystem.
• It allows Bitcoin to be used as collateral in DeFi protocols, unlocking new earning opportunities like fixed interest rates.
• The WBTC DAO, consisting of trusted stakeholders, governs the project and manages smart contract updates.
• Wrapped Bitcoin supports interoperability between Bitcoin and Ethereum, expanding Bitcoin’s utility beyond its native blockchain.

Disadvantages of Wrapped Bitcoin

• Wrapped Bitcoin relies on custodians to hold the actual Bitcoin, introducing centralization and trust risks.
• If the custodian fails or acts maliciously, WBTC holders could lose their backing Bitcoin.
• Wrapped Bitcoin inherits the security level of the Ethereum network, which is different and generally considered less secure than Bitcoin’s blockchain.
• The wrapping and unwrapping process involves transaction fees and can be complex for some users.
• Market conditions can cause wrapped tokens to lose their peg temporarily, especially in bearish markets.
• Smart contract vulnerabilities in DeFi platforms using WBTC can pose risks.
• The centralized decision-making in the WBTC DAO may lead to potential power imbalances or biased decisions.

This balance of pros and cons makes Wrapped Bitcoin a useful tool for accessing Ethereum’s DeFi ecosystem while maintaining Bitcoin exposure, but it requires trust in custodians and smart contract security.

Founders of Wrapped Bitcoin

Wrapped Bitcoin was founded as a joint project by three organizations: BitGo, Kyber Network, and Ren (previously known as Republic Protocol). These groups collaborated to create the concept of wrapped tokens using Ethereum’s ERC-20 standard, with Wrapped Bitcoin being the first wrapped token launched.

• BitGo: Founded in 2013 by Mike Belshe and Ben Davenport, BitGo acts as the custodian holding the Bitcoin reserves backing Wrapped Bitcoin.
• Kyber Network: Founded in 2017 by Loi Luu, Victor Tran, and Yaron Velner, Kyber Network is a liquidity protocol that integrates different cryptocurrency tokens and DeFi applications.
• Ren: Formerly Republic Protocol, Ren focuses on cross-blockchain integration of cryptocurrency assets and DeFi applications.

These three organizations published the Wrapped Bitcoin whitepaper in January 2019 and launched the token shortly after.

Investors and Backers

Wrapped Bitcoin was created by a consortium including BitGo, Kyber Network, and Ren. BitGo acts as the centralized custodian holding the actual Bitcoin backing each Wrapped Bitcoin token. These organizations are key investors and supporters of Wrapped Bitcoin, providing infrastructure and security for the token.

Custodians and Merchants

Custodians like BitGo securely hold the Bitcoin that backs Wrapped Bitcoin tokens. Merchants are administrators who request the minting of Wrapped Bitcoin by sending Bitcoin to custodians. This system ensures that each Wrapped Bitcoin token is fully backed by real Bitcoin.

Exchanges and Platforms

Wrapped Bitcoin is supported and traded on many major cryptocurrency exchanges such as Binance, Coinbase, and others. These platforms facilitate buying, selling, and trading Wrapped Bitcoin, attracting a wide range of investors from retail to institutional.

DeFi Users and Investors

Investors interested in decentralized finance (DeFi) use Wrapped Bitcoin to access Ethereum-based DeFi protocols without selling their Bitcoin. This group includes active DeFi users, traders, and investors seeking to leverage Bitcoin liquidity on Ethereum and other blockchains.

Institutional and Retail Investors

Wrapped Bitcoin appeals to both institutional investors and retail users who want exposure to Bitcoin’s price while participating in Ethereum’s DeFi ecosystem. Some licensed brokerages also offer Wrapped Bitcoin trading, broadening its investor base.

Halal Status of Wrapped Bitcoin

• General View on Bitcoin: Bitcoin itself is generally considered halal by many scholars because it is a decentralized digital asset with a fixed supply, similar to commodities like gold, which are permissible in Islam. It is accepted as a medium of exchange and property.

• Wrapped Bitcoin Specifics: Wrapped Bitcoin is an ERC-20 token on the Ethereum blockchain that represents Bitcoin at a 1:1 ratio. It is fully backed by verifiable Bitcoin reserves and operates transparently through a consortium of custodians.

• Concerns with DeFi Use: Using Wrapped Bitcoin in decentralized finance (DeFi) protocols often involves interest (riba), which is considered haram. Therefore, participation in most DeFi activities with Wrapped Bitcoin is likely haram.

• Conclusion: Wrapped Bitcoin itself is halal as it is backed by real Bitcoin and transparently managed. However, using it in DeFi protocols that involve interest or gambling is not halal.

Answer: No, Wrapped Bitcoin is not halal if used with most DeFi protocols due to involvement with interest (riba). But the token itself, backed by Bitcoin, is halal.
