Cryptocurrency operates across independent digital networks, each with its own rules and functionalities. These distinct blockchain networks typically do not communicate directly, creating isolated environments for digital assets. This article explains “wrapped tokens” and their role in enabling interaction within this financial ecosystem.
Wrapped tokens represent a tokenized version of another cryptocurrency. They maintain a precise 1:1 value peg to the underlying asset they represent, meaning one wrapped token is always equivalent in value to one unit of the original asset.
Wrapped tokens address the lack of direct compatibility between various blockchain networks. An asset native to one blockchain cannot typically be used on a different chain without an intermediary. Wrapped tokens bridge this gap, allowing assets from one chain to become usable on another.
Wrapped tokens enable cross-chain functionality, allowing digital assets to participate in decentralized financial applications and protocols where they otherwise could not. This expands the utility of the original asset, enabling activities like lending, borrowing, or trading on a wider array of platforms. The underlying asset remains locked on its native chain while its wrapped representation circulates on the target chain.
Creating a wrapped token involves securing the original cryptocurrency on its native blockchain. This asset is locked in a digital vault or smart contract. Once locked, an equivalent amount of the wrapped token is generated on the target blockchain.
Unwrapping or redeeming a wrapped token reverses this process. The wrapped token is burned on the target blockchain. This triggers the release of the original, locked asset from its vault or smart contract on its native blockchain, returning it to the owner.
Custodians or minters manage the locking and unlocking mechanism. Some systems use a centralized entity, like a company, as the custodian, holding original assets and issuing wrapped versions. This model introduces counterparty risk and often involves regular audits to verify reserves. Other systems employ decentralized mechanisms, relying on smart contracts or decentralized autonomous organizations (DAOs) to manage the process.
Fees are typically associated with the wrapping and unwrapping processes, covering operational costs or network transaction fees. These costs can vary depending on the specific service or network conditions. The Internal Revenue Service (IRS) generally treats cryptocurrency as property, meaning exchanging one cryptocurrency for another can be a taxable event. However, merely wrapping an asset you own may not trigger a taxable event until that wrapped asset is sold or exchanged.
A defining characteristic of wrapped tokens is their asset-backed nature, meaning each wrapped token is fully collateralized by an equivalent amount of the underlying asset. This backing provides the foundation for their value, similar to how certain financial instruments are backed by specific reserves.
The pegging mechanism maintains the 1:1 value relationship through the systematic process of minting new wrapped tokens when the underlying asset is locked, and burning them when the asset is unlocked. This continuous balancing act ensures that the supply of wrapped tokens accurately reflects the reserved underlying assets.
Wrapped tokens exhibit fungibility, meaning that each token of a specific wrapped asset type is interchangeable with any other token of the same type. This fungibility is important for market liquidity and for seamless trading and integration within decentralized applications, mirroring the fungibility of traditional currency or shares of a company.
The primary function of wrapped tokens is to extend the utility of an asset to blockchain networks where it would not natively exist. This allows assets to participate in specific decentralized applications, protocols, and financial activities on otherwise incompatible chains. By enabling this cross-chain movement, wrapped tokens significantly broaden the operational scope and potential financial engagement for various digital assets.
Wrapped Bitcoin (wBTC) brings Bitcoin’s value onto the Ethereum blockchain. Bitcoin is not natively compatible with Ethereum’s extensive decentralized finance (DeFi) ecosystem. wBTC allows Bitcoin holders to utilize their assets within Ethereum-based applications, such as lending protocols and decentralized exchanges, without selling their original Bitcoin.
Similarly, Wrapped Ethereum (wETH) serves a distinct purpose within the Ethereum network itself. While Ethereum (ETH) is the native currency of its blockchain, many decentralized applications and smart contracts on Ethereum utilize a different token standard, ERC-20. To enable ETH to interact seamlessly with these ERC-20 compliant applications, wETH was created as an ERC-20 representation of ETH, allowing it to be used in smart contracts that require this specific token standard.
Another example includes wrapped versions of various stablecoins or other cryptocurrencies, allowing them to traverse different blockchain networks. These examples illustrate how wrapped tokens consistently enable greater interoperability and expand the financial reach of diverse digital assets across the fragmented blockchain landscape.
