Wrapped tokens are a cryptographic asset that represents another underlying asset. It involves the process of pegging the value of the original asset to a token on a different blockchain. This is typically done to enable the use of the original asset on a different blockchain or within a decentralized ecosystem.

The process of wrapping involves locking the original asset in a smart contract on its native blockchain, and in return, an equivalent amount of wrapped tokens is minted on the destination blockchain. These wrapped tokens are essentially a representation of the original asset and can be freely traded and utilized within the ecosystem of the destination blockchain.

One common example is wrapped Bitcoin (WBTC), where Bitcoin is locked in a smart contract on the Bitcoin blockchain, and an equivalent amount of WBTC is issued on the Ethereum blockchain. This allows users to interact with Bitcoin on the Ethereum network, opening up possibilities for decentralized finance (DeFi) applications, decentralized exchanges, and other blockchain-based services.

Wrapped tokens facilitate interoperability between different blockchain networks, providing users with more flexibility and options for utilizing their assets across various decentralized platforms. It’s important to note that the wrapped token’s value is pegged to the original asset it represents, and there is a trust element involved in the custodianship of the locked assets and the issuance of the wrapped tokens.

Wrapped tokens operate through a process known as token wrapping, and the mechanism involves locking an asset on its native blockchain and issuing an equivalent representation on another blockchain. Here’s a detailed breakdown of how wrapped tokens work:

  1. Asset Locking:
    • The process begins with a user who wants to move an asset from one blockchain to another. This could be driven by the desire to utilize the asset in a different blockchain ecosystem, take advantage of specific features or applications, or participate in decentralized finance (DeFi) activities.
    • The user initiates the wrapping process by depositing the original asset into a smart contract on its native blockchain. This smart contract holds and secures the locked asset.
  2. Issuance of Wrapped Tokens:
    • Once the original asset is locked in the smart contract, an equivalent amount of wrapped tokens is minted and issued on the target blockchain. These wrapped tokens are fungible and can be freely traded and transacted within the destination blockchain’s ecosystem.
    • The issuance of wrapped tokens is typically managed by a set of rules encoded in a smart contract, ensuring a one-to-one pegging with the original asset. For example, if a user locks 1 Bitcoin, they receive 1 wrapped Bitcoin on the target blockchain.
  3. Custodianship and Trust:
    • The custody of the locked assets is a critical aspect of wrapped tokens. Trust is placed in the entity or consortium responsible for managing the smart contract on the native blockchain and ensuring the proper issuance and burning of wrapped tokens.
    • This custodian is often a centralized entity or a consortium of entities responsible for maintaining transparency, security, and the one-to-one pegging of the wrapped tokens to the locked assets. Users need confidence that the wrapped tokens can be redeemed for the original assets at any time.
  4. Utilization on Target Blockchain:
    • Once issued, wrapped tokens can be freely transferred and utilized on the target blockchain. Users can engage in decentralized exchanges, lend their assets in DeFi protocols, participate in yield farming, or leverage other blockchain-based services.
  5. Redemption and Unwrapping:
    • If a user decides to move the assets back to the original blockchain, they can initiate the unwrapping process. This involves sending the wrapped tokens to the smart contract on the target blockchain, and in return, the equivalent amount of the original asset is released from the smart contract on its native blockchain.

Wrapped tokens provide interoperability between different blockchain networks, allowing users to access and use assets across various decentralized platforms while maintaining a link to the value of the original asset. The success of wrapped tokens relies on the trustworthiness and reliability of the custodian managing the wrapping process.
