About Wrapped Bitcoin (WBTC)

Wrapped Bitcoin Frequently Asked Questions (FAQ)

What is Wrapped Bitcoin (WBTC) and how does it function on the Ethereum blockchain?


Wrapped Bitcoin (WBTC) is a tokenized version of Bitcoin (BTC) that operates on the Ethereum blockchain. It represents Bitcoin at a 1:1 ratio, allowing Bitcoin holders to use their BTC in the Ethereum ecosystem, including participating in smart contracts and decentralized applications (DApps). WBTC functions on Ethereum as an ERC-20 token, enabling Bitcoin to be used with the speed and flexibility of Ethereum's network while maintaining the same value as BTC. It's minted through a process involving custody by trusted entities and can be redeemed for actual Bitcoin.




Can you explain the process of creating Wrapped Bitcoin (WBTC)?


Wrapped Bitcoin (WBTC) is created through a process called wrapping, where Bitcoin is held in reserve by a custodian. To create WBTC, a user sends Bitcoin to the custodian's wallet. The custodian then mints the equivalent amount of WBTC tokens on the Ethereum blockchain. These WBTC tokens can be used in the Ethereum ecosystem, while the original BTC remains locked and out of circulation until the WBTC is redeemed for Bitcoin.




What are the use cases of Wrapped Bitcoin (WBTC) within the Ethereum DeFi ecosystem?


Wrapped Bitcoin (WBTC) facilitates Bitcoin's integration into the Ethereum DeFi ecosystem, enabling BTC holders to participate in Ethereum-based decentralized finance applications. Use cases include yield farming, liquidity provision, collateralized lending and borrowing, decentralized trading on DEXes, and access to Ethereum's smart contract functionalities.




Who are the key organizations behind the development of Wrapped Bitcoin (WBTC)?


Wrapped Bitcoin (WBTC) is a collaborative project primarily developed by BitGo, Ren, and Kyber Network. BitGo is the primary custodian, responsible for holding the actual bitcoin and issuing WBTC tokens, while Kyber Network and Ren help facilitate the decentralized exchange and integration into the Ethereum ecosystem.




How is Wrapped Bitcoin (WBTC) different from the original Bitcoin (BTC)?


Wrapped Bitcoin (WBTC) is a token that represents Bitcoin on the Ethereum blockchain. It is different from the original Bitcoin (BTC) in that it operates within the Ethereum ecosystem, allowing BTC to be used in Ethereum's decentralized finance (DeFi) applications. WBTC is an ERC-20 token, which means it is compliant with Ethereum's token standards and can interact with smart contracts, dapps, and protocols on Ethereum, providing liquidity and integration between the two separate blockchain networks.




How is the value of Wrapped Bitcoin (WBTC) maintained equal to Bitcoin (BTC)?


The value of Wrapped Bitcoin (WBTC) is maintained equal to Bitcoin (BTC) through a process called 'pegging,' where 1 WBTC is backed by 1 BTC in reserve. This is ensured by custodians who hold the equivalent amount of BTC for every WBTC in circulation, allowing users to redeem WBTC for BTC at a 1:1 ratio. This backing maintains the parity between WBTC’s and BTC’s value.




What security measures are in place for Wrapped Bitcoin (WBTC) on the Ethereum network?


Wrapped Bitcoin (WBTC) employs several security measures on the Ethereum network including: 1) A transparent verification process through on-chain proof of reserves matching minted WBTC tokens with the actual BTC in custody, 2) Utilization of a consortium of trusted and vetted custodians and merchants to ensure secure management and distribution of WBTC, and 3) Regular audits by third-party security firms to validate that the underlying Bitcoin holdings are secure and fully back the WBTC in circulation.




What impact has Wrapped Bitcoin (WBTC) had on the liquidity and integration of Bitcoin into the Ethereum ecosystem?


Wrapped Bitcoin (WBTC) has significantly enhanced the liquidity of Bitcoin within the Ethereum ecosystem by allowing Bitcoin holders to participate in Ethereum's decentralized finance (DeFi) applications. WBTC has bridged the gap between the two blockchains, enabling Bitcoin to be used for activities like lending, borrowing, and yield farming, which has further integrated Bitcoin with Ethereum-based financial services and smart contracts.




Is Wrapped Bitcoin (WBTC) available on blockchain networks other than Ethereum, and if so, which ones?


As of mid 2023, Wrapped Bitcoin (WBTC) is primarily available on the Ethereum blockchain as an ERC-20 token. There are no official reports of it being supported on other blockchains. However, different protocols or platforms may create their own versions of wrapped assets on other networks, but these would be separate from the official WBTC on Ethereum.
