What are Bitcoin and Ethereum?
These are the two biggest and the most famous cryptocurrencies in the world, and it can’t be that you’ve never heard of them.
But still, Bitcoin (ticker BTC) is a form of digital currency that meets the need of central authorities such as banks or governments. Instead, Bitcoin uses a peer-to-peer internet network to confirm purchases directly between users.
Launched in 2009 by a mysterious developer known as Satoshi Nakamoto, Bitcoin (BTC) was the first and most valuable entrant in the emerging class of assets known as cryptocurrencies.
Ethereum is a decentralized blockchain with smart contract functionality. Ether (ticker ETH or Ξ) is the native cryptocurrency of the platform. Among cryptocurrencies, Ether is second to Bitcoin in market capitalization. Ethereum was launched in 2013 by a programmer Vitalik Buterin.
What is a wrapped coin/token?
Wrapped Bitcoin (WBTC) brings Bitcoin (BTC) to the Ethereum (ETH) blockchain. Why is that so crucial? One of the main points is that WBTC is in decentralized finance and it provides the owners of cryptocurrency with the freedom to explore other blockchains. If you want, it’s a kind of a bridge between a BTC coin and an Ethereum platform.
Wrapped tokens are cryptocurrencies that are implemented in a different blockchain. The reason that wrapped tokens exist is for interoperability, which is the ability of a coin to work in a blockchain that normally does not support it.
Benefits of wrapped tokens
- Wrapped cryptocurrencies boost the utility and liquidity of smart contract platforms and well-known decentralized finance (DeFi) apps.
- Other reasons to wrap cryptocurrencies may include ERC-20 token swapping or taking advantage of blockchain functions that a crypto asset might not have on its native chain.
- It’s faster and cheaper to make transactions using a wrapped version of BTC.
- The majority of blockchains have their own token standards and they sometimes can’t be used across multiple chains. Wrapped tokens allow non-native tokens to be used on a given blockchain.
- It’s quick. As for buying or selling Bitcoin, it could be quite time-consuming. But a wrapped Bitcoin (WBTC) in the Ethereum network is way quicker.
- When you wrap a token, you actually increase the security of your assets because you have control over private keys. Plus, intermediaries (DAO, smart contracts, or a wallet) focus on safe exchanges.
And yet some drawbacks
Wrapped tokens still depend on a custodian to be minted (wrap) or burned (unwrap). If the custodian is somehow flawed, the wrapping or unwrapping process will be flawed as well.
- Expensive minting
It’s quite evident that wrapping and unwrapping tokens are followed by gas fees, which can lead to slippage.
The pivotal point of cryptocurrencies is to be a decentralized system. But wrapped tokens are issued by a custodian, and they tend to be centralized. According to Vitalik Buterin, wrapped tokens are “sensitive” to centralization because they’re created in a centralized manner.
The matter is that wrapped tokens are minted through a central program, so they are an object of centralization.
Good news, the benefits of wrapped tokens compensate for the negative sides though.
How to wrap BTC?
A wrapped BTC is a digital form of BTC blockchains that support smart contracts such as Ethereum, Solana, Polkadot, Binance Chain. Wrapped assets are just tokenized versions of Bitcoin that meet the token requirements of DeFi-supporting blockchains.
Bitcoin wrapping techniques
Here are three different options for tokenizing Bitcoin, all of them ask a user to lock BTC or other assets to get tokens pegged to the value of Bitcoin:
This technique involves an intermediary. In this case, you need to send a necessary amount of BTC to a centralized custodial platform. After, this platform will lock your Bitcoin in a smart contract and mint an equal amount of tokenized Bitcoin on Ethereum or any other blockchain you need. Finally, the dealer will transfer the tokenized Bitcoin, WBTC, directly to your wallet.
Using the following option, you do not need to trust a centralized side. You can send your Bitcoin to a smart contract adapted to mint tokenized Bitcoin quantity to the amount of locked BTC. Keep Network could be a good example of a system that uses a trustless technique.
The last Bitcoin wrapping option empowers users to get synthetic assets pegged to the Bitcoin value. Synthetic wrapping does not necessarily utilize BTC coin to mint a Bitcoin-pegged synthetic token. You can lock a combination of assets to mint synthetic Bitcoin. It really depends on the protocol you use.
How to wrap Ether (ETH)?
The process of generating WETH is fairly simple - you send your ETH to a smart contract that then sends WETH in return. This means that all WETH
minted is backed up entirely by ETH reserves. To begin with, your ETH is locked in the smart contract and can be exchanged back at any time for WETH. When your ETH is returned, the contract burns the supplied WETH.
To wrap Ether directly with the WETH smart contract, you need some ETHs and credit your wallet with WETH at a 1:1 proportion (you still need to pay transaction fees). Actually, it's much easier to swap another token for WETH using a crypto exchange.
Where to buy a wrapped BTC?
Here are the most prominent and convenient ways to get BTC through an exchange. Let’s pick up 5 of them just as an example:

Wrapping that up
Wrapped tokens build a bridge between various blockchains. A wrapped token is, by nature, a tokenized version of an asset that natively operates on another blockchain. One of the biggest pros of wrapped tokens is that they provide greater scalability between different cryptocurrencies and blockchains and widen the opportunities for developers and traders.
