  Wrapped bitcoin, also known as WBTC, is a tokenized version of bitcoin that runs on the Ethereum blockchain. It works by locking up bitcoin in a smart contract and issuing an equivalent amount of WBTC tokens. This allows bitcoin holders to access the benefits of the Ethereum ecosystem, such as decentralized finance (DeFi) applications and smart contracts. The mechanism involves a custodian who holds the bitcoin and mints the WBTC tokens. The custodian ensures that the number of WBTC tokens in circulation is always backed by an equal amount of bitcoin held in reserve. This ensures the transparency and security of the wrapped bitcoin system.

  The working mechanism of wrapped bitcoin can be understood as a bridge between the Bitcoin and Ethereum networks. When a user wants to wrap their bitcoin, they send it to a custodian who holds the bitcoin in a secure wallet. The custodian then mints an equivalent amount of WBTC tokens on the Ethereum blockchain, which are sent back to the user. These WBTC tokens can then be used on the Ethereum network for various purposes, such as trading, lending, or providing liquidity. When a user wants to unwrap their WBTC tokens and get back their original bitcoin, they simply send the WBTC tokens back to the custodian, who then burns the tokens and releases the locked bitcoin to the user.
