Furthermore, they are crucial in enhancing liquidity, increasing accessibility, and bridging the gaps between blockchain ecosystems.
In this article, we’ll explore wrapped tokens, how they work, their benefits, and their challenges.
What is a Wrapped Token?
A wrapped token is a digital asset that represents another cryptocurrency or asset. The concept of wrapped tokens emerged as a solution to the siloed nature of blockchains. Traditionally, they operated independently, limiting asset and data interoperability. The first wrapped token was WBTC (Wrapped Bitcoin) and it was created in 2019, aiming to bring the liquidity of BTC to Ethereum.
Wrapping entails locking native tokens in a smart contract on their original blockchain and minting corresponding wrapped versions on a target blockchain. As a result, these tokens maintain a 1:1 ratio with their underlying asset, ensuring their value remains identical. For example, Wrapped Bitcoin (WBTC) represents Bitcoin (BTC) on the Ethereum blockchain, allowing users to utilize BTC in Ethereum-based decentralized applications (dApps).
Understanding Wrapped Tokens
Each blockchain operates as an independent entity, which can consequently limit the ability of assets to interact across networks. In contrast, wrapped tokens bridge this gap by enabling users to utilize their assets on a target blockchain without leaving the original blockchain. For example, with wrapped tokens, users can utilize Bitcoin on the Ethereum network, without ever transferring the original asset.
Popular Wrapped Tokens
There are many wrapped tokens available on the market but some of the most popular ones include:
- Wrapped Bitcoin (WBTC): Allows users to utilize Bitcoin in different DeFi applications on various blockchain networks.
- Wrapped Ether (WETH): Converts Ethereum’s native token, ETH, into an ERC-20 token compatible with different DeFi protocols.
- Wrapped Binance Coin (WBNB): Represents Binance Coin (BNB) on other blockchains for expanded use cases.
Consequently, these tokens have become integral to the DeFi ecosystem, offering increased utility and versatility for digital assets.
How Do Wrapped Tokens Work?
The creation and management of wrapped tokens involves a process that ensures transparency, security, and liquidity. Here’s how it works:
The Wrapping Process Explained
Wrapping a token involves locking the native asset in a smart contract on its original blockchain. Once locked, an equivalent amount of the locked token is minted (created) on the target blockchain. For example:
- A user wants to wrap 1 BTC into WBTC on Ethereum.
- The user deposits 1 BTC into a designated smart contract.
- A custodian or protocol mints 1 WBTC on the Ethereum blockchain, ensuring 1:1 backing.
This process ensures that every wrapped token is fully collateralized by its native counterpart.
The Unwrapping Process
Unwrapping a token is the reverse of wrapping. It involves exchanging (burning) wrapped versions of tokens for the original asset locked in the smart contract. When a user wants to redeem their wrapped token:
- They send their WBTC to the designated smart contract.
- The smart contract burns (removes from circulation) the corresponding amount of WBTC.
- The custodian releases an equivalent amount of BTC and returns it to the user.
This redemption process guarantees that the supply of wrapped tokens aligns with the collateralized native assets.
The Role Of Smart Contracts
Smart contracts are the backbone of the wrapping and unwrapping processes. Since smart contracts are fully automated, they leave no room for human error when it comes to execution. At the same time, they ensure three crucial elements:
- Transparency: All transactions and asset holdings are publicly verified on the blockchain.
- Security: Locked assets are safe within the smart contract, reducing the risk of unauthorized access.
- Automation: The entire process is self-executing, minimizing human intervention.
Why Were Wrapped Tokens Developed?
Wrapped tokens were created to address some of the most pressing challenges in the blockchain ecosystem. Blockchains often operate as isolated networks, making it difficult for assets to move seamlessly between them. As a result, this lack of interoperability leads to inefficiencies, limited liquidity, and reduced usability of digital assets.
Wrapped tokens solve these issues by enabling cross-chain transactions and enhancing asset utility. In addition, users can leverage these highly liquid assets in DeFi, lending, and other applications without sacrificing their original value by tokenizing assets like Bitcoin or Ether on different blockchains.
Use Cases for Wrapped Tokens
Wrapped tokens have a variety of applications that make them indispensable in the DeFi ecosystem and beyond. These include:
- DeFi Applications: Wrapped tokens enable users to participate in yield farming, liquidity provision, and staking across multiple platforms.
- Cross-Chain Interoperability: They allow assets to move seamlessly between blockchains, broadening their use cases as a result.
- Trading: Traders can use wrapped tokens to access liquidity pools and decentralized exchanges that don’t natively support the underlying asset.
DeFi isn’t the only sector where wrapped tokens find use. In other words, cross-chain interoperability means that developers and users can utilize them in practically any type of application, no matter the blockchain.
Key Benefits of Wrapped Tokens
Wrapped tokens offer several advantages that make them a vital tool in the crypto ecosystem. Here are some of their key benefits:
- Increased Liquidity: By bringing assets from one blockchain to another, wrapped tokens enhance the liquidity of decentralized exchanges and DeFi protocols.
- Interoperability: They bridge the gap between blockchains, allowing assets to interact across networks.
- Expanded Use Cases: Wrapped tokens enable assets like BTC to be used in ecosystems that don’t natively support them, such as Ethereum or Solana-based dApps.
- Accessibility: Users can leverage their assets in a broader range of applications without selling or converting them.
- Transparency: The backing of wrapped tokens is verifiable on the blockchain, ensuring trust and accountability.
Challenges and Limitations of Wrapped Tokens
Wrapped tokens improve the crypto ecosystem but despite their many benefits, they have their own set of challenges. Some of the potential risks and limitations of wrapped tokens include:
- Security Risks: Wrapped tokens rely on custodians or smart contracts to hold the underlying assets. If the custodian gets compromised or if there’s an error in the smart contract code, user funds may be at risk.
- Regulatory Uncertainty: The legal framework for wrapped tokens is still evolving, which could lead to compliance challenges in the future.
- Centralization Concerns: Many wrapped token protocols depend on centralized custodians. Therefore, this may undermine the decentralized ethos of blockchain technology.
- High Operational Costs: Wrapping and unwrapping tokens often involves transaction fees. On some networks with higher gas fees, such as Ethereum, these can add up over time.
Getting Started with Wrapped Tokens
If you’re interested in using wrapped tokens, here’s how you can get started:
- Choose a Platform: Select a trusted DeFi platform or crypto wallet that supports wrapped tokens.
- Understand the Process: Familiarize yourself with the wrapping and unwrapping processes, including associated fees and security measures.
- Select a Custodian or Protocol: Ensure the custodian or protocol managing the wrapped tokens has a strong track record of security and transparency.
- Start Small: Begin with a small amount to test the process before committing larger sums. For example, you don’t have to start with 1 BTC or 1 ETH, you can just wrap a fraction of that.
- Monitor the Market: Keep an eye on wrapped token prices and liquidity to make informed decisions.
What Does the Future Hold?
Wrapped tokens have revolutionized the crypto space, opening new opportunities for projects and new use cases for the most popular tokens on the market. Despite that, they keep evolving to meet the needs of the wider crypto ecosystem. Here’s what we can expect in the future:
