What Are Wrapped Crypto Tokens? A Comprehensive Guide
Table of Contents
Recently, wrapped crypto tokens have become relatively popular among digital assets. Considering the problem of interoperability between multiple blockchains, these tokens have evolved into a creative solution to some of the challenges in the distributed finance (DeFi) space.
This guide demystifies wrapped crypto coins by clarifying their nature, operation, advantages, and constraints.
Understanding Wrapped Crypto Tokens
Blockchains are, by their very nature, isolated ecosystems; tokens unique to one blockchain usually cannot be utilized on another. Wrapped crypto tokens are special assets that are built on a blockchain that is different from the underlying asset. For instance, wrapped Bitcoin (wBTC) can be found on the Ethereum network, but BTC can only be found on the Bitcoin network.
How Do Wrapped Tokens Work?
The process of creating a wrapped token involves several key steps and participants:
- The Original Asset: This is the asset—such as Ethereum or Bitcoin—that will be wrapped.
- The Custodian: This person is in charge of keeping the original asset on hand as a backup. A smart contract, a person, or a business could serve as this custodian. Regardless, the custodian must store the underlying asset safely. The integrity of the wrapped tokens greatly depends on their reliability.
- The Minting Process: The custodian gets the original asset first, then mints equal numbers of wrapped tokens. If you deposit one Bitcoin, for example, a custodian will return one wBTC.
- Using Wrapped Tokens: Wrapped tokens, once generated, can be used on the designated blockchain. They can collateral, staked, or traded assets in distributed finance (DeFi) systems.
- Redeeming Wrapped Tokens: Should you wish to restore your wrapped tokens to their original asset, the reverse method is used. You mail your wrapped tokens to the custodian, who “burns” (destroys) them and then sends back the underlying asset to you.
A Case Study of Wrapped Bitcoin
Among the most well-known instances of wrapped tokens is wrapped Bitcoin (wBTC). They’re designed to move Bitcoin’s liquidity to the Ethereum blockchain, where it may be utilized in several DeFi apps. It was built around the ERC-20 token standard, as Ethereum-based DeFi systems were not accessible to Bitcoin holders prior to wBTC.
BitGo and Kyber Network were among numerous blockchain firms working together to create wBTC. To wrap Bitcoin, the trader deposits BTC with a custodian who subsequently mints an identical quantity of wBTC. This wBTC can be used on Ethereum-based systems for lending, borrowing, and yield farming.
Advantages of Wrapped Crypto Tokens
Wrapped tokens have a number of benefits, especially in cross-chain operability and decentralized finance. One main advantage of wrapped tokens is their capacity to allow cross-chain functionality, greatly enhancing their liquidity and value.
Using their BTC as wBTC on the Ethereum blockchain, for example, allows Bitcoin holders to access a variety of DeFi apps. Wrapped tokens give holders of non-Ethereum assets access to the vibrant DeFi ecosystem on Ethereum. This allows them to access opportunities like yields, loan market participation, and other interests. Wrapping assets’ usage on several blockchains enhances their whole value proposition.
Challenges of Wrapped Tokens
Beyond their benefits, wrapped tokens have their disadvantages. First, there are centralization risks. Usually, the process of wrapping tokens entails a centralized custodian, which creates a point of trust and possible risk.
Should the custodian fail, get hacked, or act maliciously, the integrity of the tokens could be in jeopardy. Also, the procedure of wrapping and unwrapping tokens can be difficult, particularly for new users.
The adoption process may be hampered by its intricacy – sealing with custodians, grasping smart contracts, and handling several kinds of tokens. The utility of the wrapped token depends on keeping a 1:1 peg between it and the underlying asset.
In volatile markets, however, there may be minor variations in value, especially if the asset being wrapped is highly volatile or if there are problems with the custodian. Additionally, the wrapping and unwrapping fees can mount up, particularly for regular purchases. Though they are extra expenses to consumers, these fees are required to pay for custody, minting, and burning.
Final Thoughts
By letting assets migrate across several blockchain systems, wrapped tokens create fresh opportunities for asset use and financial inclusion. Still, they present a unique set of issues that demand cautious management.
Examples of such issues include centralization, complexity, and the possibility of value variances. As the infrastructure and technology supporting wrapped tokens keep developing, they will become essential in the crypto ecosystem since they give consumers more freedom and more chances to engage in the digital economy.
