Wrapped Bitcoin (WBTC) is a cryptocurrency that operates on the Bitcoin network, but with a twist. It is an ERC-20 token that represents Bitcoin on the Ethereum platform. WBTC is created by “wrapping” Bitcoin, which involves locking up Bitcoin in exchange for WBTC.
This process allows users to access the benefits of the Ethereum platform, such as smart contracts, while still holding Bitcoin. WBTC is created by combining multiple inputs, known as unspent transaction outputs (UTXOs), from previous transactions. These inputs and outputs are validated by successful validators on the network, who are rewarded with fees paid in WBTC. In this blog, we’ll explore everything you need to know about WBTC.
WBTC Mechanism of Working
Wrapped Bitcoin (WBTC) is a cryptocurrency that operates on the Ethereum blockchain. It works by using a custodian system that securely holds Bitcoin reserves while issuing WBTC tokens on the Ethereum blockchain. These tokens are designed to represent the exact same amount of Bitcoin held in reserve, making them fully backed and ensuring their value is always equivalent to that of Bitcoin.
By converting Bitcoin to WBTC, users can benefit from the advantages of the Ethereum blockchain, such as faster transaction times and lower fees. They can also access a wide range of decentralized finance (DeFi) services, including lending and borrowing, trading, and more.
To convert Bitcoin to WBTC, users simply need to send their Bitcoin to a WBTC custodian, who will then issue them with an equivalent amount of WBTC tokens. Users can then trade, hold, or use these tokens to access Ethereum DeFi services.
Overall, WBTC provides a bridge between the Bitcoin and Ethereum ecosystems, allowing users to enjoy the benefits of both while retaining the security and stability of Bitcoin.
What are ERC-20 Tokens?
ERC-20 tokens are a type of digital asset that are built on the Ethereum blockchain. They are standardized tokens that follow a specific set of rules and functions, allowing them to be easily integrated into the Ethereum ecosystem.
ERC-20 tokens can be used for a variety of purposes, including fundraising, trading, and access to decentralized applications (dApps). They are often used as a token that represents Bitcoin, such as Wrapped Bitcoin (WBTC), which is an ERC-20 token that is backed by Bitcoin.
To mint ERC-20 tokens, merchants and custodians must follow the ERC-20 standard rules and functions, including how the token is created, how it is transferred, and how it interacts with other tokens and contracts on the Ethereum blockchain.
ERC-20 tokens have become increasingly popular in recent years, with a wide range of projects and companies using them for fundraising and tokenization purposes. They provide a flexible and powerful tool for building decentralized applications and creating digital assets that can be easily traded and transferred on the Ethereum blockchain.
