IntroductionBitcoin is the world no.1 Cryptocurrency, it’s the largest by market capitalisation, most famous and traded stable coin with all the advantages that it brings it’s not able to enter into the world of DeFi and it’s applications, That’s where Wrapped bitcoin comes in.
Most people may have heard of wrapped tokens but don’t fully know what it is.
Lemme explain that before we talk about wrapped bitcoins: We know both Bitcoin and Ethereum have different functions and protocols and operate on different blockchains, there’s no way bitcoin can be used on an ethereum blockchain. So in order for you to access bitcoin on ethereum blockchain it is wrapped (as a form of disguise lol).
So Wrapped tokens are cryptocurrencies that have their values/price attached to another crypto, which can be used to bridge gap between blockchains or networks and create interaction in the crypto space(interoperability). They’re usually managed by a third party/ custodian who wraps and unwraps the assets.
Wrapped Bitcoin:The Process of Wrapping involves three parties ;
1. The Merchant who triggers the process by sending BTC to the custodian after receiving a request from the user
2. The Custodian who holds and locks the BTC and ensures it’s secure.
3. The User who makes the request to use BTC in DeFi.
Any User who’s interested in wrapping their BTC first deposits BTC and makes a request to the merchant who transfers the exact deposited BTC to the custodian’s address. The Custodian locks the BTC and an equivalent WBTC is minted on ethereum. If you want your BTC back u just have to burn the WBTC and your BTC is released back to you.
There are about five versions of wrapped bitcoin
1.
WBTC: The first version of wrapped bitcoin to be launched in January 2019 by BitGo, and still the most used. It is an ERC-20 token designed to represent bitcoin in the ethereum blockchain maintained by an organisation of over 30 members WBTC DAO. It has helped BTC holders to participate in the ethereum DeFi ecosystem with lots of opportunities. It is valued at 1:1 with BTC. Fully transparent with proof of reserves across chains
2.
tBTC: This one has no custodians, it is a decentralised Bitcoin to Ethereum bridge that requires no one to hold custody of the BTC. It is valued at 1:1 on the threshold network. The bridge is also transparent and has up to date proof of reserve.
3.
sBTC: This one is a synthetic bitcoin token that tracks the price of BTC through oracles instead of reserve on the synthetix ecosystem. But recently it has proven to be more than just the synthetic platforms
4.
cbBTC: Recently launched on September 2024 is the Coinbase wrapped bitcoin token that allows users to use BTC on the Ethereum and Base network. The Custody is solely managed by Coinbase unlike WBTC.
5.
renBTC: which was launched by the ren protocol but a suffered a great loss due to the bankruptcy of its owner in 2021. It was shut down in late 2022 but allowed users to bridge their assets back to BTC before shutdown to avoid losses.
Conclusion:
Bitcoin has made it’s mark on the cryptocurrency world, overtime it has proven to be profitable, dependable and sustainable with many multinational institutions owning it and many businesses accepting it as payment.
As the need for the use of bitcoin keeps rising and the numerous opportunities DeFi provides, Wrapped bitcoin becomes more and more important.
Finally in the quest for the best wrapped Bitcoin, WBTC is miles ahead of others on all fronts;- liquidity, transparency, and decentralization.
