Wrapped Bitcoin (WBTC) is an ERC20 token that represents Bitcoin. It is the first token backed 1:1 with Bitcoin, so one WBTC equals one BTC. Being an ERC20 token, WBTC transactions are much faster than Bitcoin, although the advantage is in the integration in Ethereum wallets, dapps and smart contracts.
For the trust of users, Wrapped Bitcoin is regulated by audit and publishes all the verifications and chain transactions of the Ethereum and Bitcoin networks.
The team needs to finish the project as it is very limited in various details, it must even improve its roadmap to solidify its platform and earn the recognition it deserves. However, it still remains a great practical and scalable promising project where many will benefit.
