Introduction to Wrapped Tokens
One of the biggest challenges facing the blockchain and cryptocurrency industry is the lack of interoperability between different blockchains and their respective digital assets. Blockchains, by design, cannot enable direct cross-chain transfer of assets, which has become a crucial issue for cryptocurrencies and decentralized finance (DeFi).
Addressing the Lack of Blockchain Interoperability
DeFi is predominantly based on the Ethereum blockchain, while many other coins and tokens exist across multiple other blockchains. This has created a need for solutions that can facilitate the transfer of value across these siloed blockchain networks. Wrapped tokens are digital assets that represent the exact value of an original cryptocurrency from a different blockchain or follow a different token standard than the chain they are on.
Definition and Purpose of Wrapped Tokens
Wrapping original tokens to mint new tokens that are compliant with another blockchain allows users to use assets from one chain on another chain entirely. This enables the transfer of value across blockchains, which otherwise lack blockchain interoperability and cryptocurrency cross-chain transfer capabilities. Wrapped tokens play a crucial role in improving decentralized finance by providing a bridge between different cryptocurrency representation on various blockchain networks.
| Wrapped Token | Underlying Asset | Blockchain |
|---|---|---|
| Wrapped Bitcoin (WBTC) | Bitcoin (BTC) | Ethereum (ETH) |
| Wrapped Ether (WETH) | Ether (ETH) | Ethereum (ETH) |
| renDOGE | Dogecoin (DOGE) | Ethereum (ETH) |
“Wrapped tokens enable assets like Bitcoin to function on different blockchains, enhancing interoperability in the DeFi ecosystem.”
How Wrapped Tokens Work
The world of wrapped tokens revolves around three key players: merchants, custodians, and decentralized autonomous organizations (DAOs). Merchants are the entities responsible for locking their cryptocurrencies to mint new wrapped tokens on the target blockchain or burning wrapped tokens to free up the locked cryptocurrencies. Custodians are the organizations tasked with securing the cryptocurrency reserves on the native blockchain. Finally, the Wrapped Tokens DAO is a decentralized autonomous organization that collectively decides on the custodians and merchants to add or remove from the network.
The Wrapping and Unwrapping Process
The wrapping process involves swapping one token for another in an equal amount via a smart contract on the blockchain. This mints a new token that represents the original coin, allowing it to be used on a non-native blockchain. To exchange a wrapped token for the original unwrapped cryptocurrency, the wrapped token must be destroyed through a process called burning.
Key Players: Merchants, Custodians, and DAOs
- Merchants are the entities that lock their cryptocurrencies to mint new wrapped tokens on the target blockchain or burn wrapped tokens to free up the locked cryptocurrencies.
- Custodians are the organizations responsible for securing the cryptocurrency reserves on the native blockchain.
- The Wrapped Tokens DAO is a decentralized autonomous organization that collectively decides on the custodians and merchants to add or remove from the network.
The process of wrapped token minting and wrapped token burning is crucial in the wrapped token ecosystem, facilitated by the merchants. The custodians play a vital custodian role in securing the underlying cryptocurrencies, while the Wrapped Tokens DAO oversees the network of wrapped token key players.
Popular Wrapped Tokens
In the blockchain and cryptocurrency industries, one of the main problems highlighted is the lack of interoperability between various blockchains and their corresponding assets. Wrapped tokens address this issue by facilitating the transfer of assets between different blockchains and enabling their use in the broader cryptocurrency ecosystem.
Wrapped Bitcoin (WBTC)
One of the most prominent examples of a wrapped token is Wrapped Bitcoin (WBTC). WBTC allows Bitcoin to be used on the Ethereum blockchain, making it compatible with the ERC-20 token standard and enabling its integration into the decentralized finance (DeFi) ecosystem. WBTC is a joint initiative run by three Web3 entities: Kyber, Ren, and BitGo, which collectively manage the minting and burning of WBTC, as well as the addition and removal of merchants and custodians.
Wrapped Ether (WETH)
Another popular wrapped token is Wrapped Ether (WETH), which is used to represent Ether on the Ethereum blockchain. Since Ether was created before the ERC-20 token standard was established, it does not natively comply with the ERC-20 standard. WETH is used to make Ether compatible with the ERC-20 standard and enable its use across various DeFi protocols on Ethereum.
Wrapped tokens play a crucial role in increasing the liquidity of assets, enabling cross-chain transactions, and providing access to a wide array of decentralized finance services. They represent a significant development in the cryptocurrency space, addressing the issue of blockchain interoperability and expanding the possibilities of the Web3 ecosystem.

Benefits of Using Wrapped Tokens
Wrapped tokens offer a range of benefits that are transforming the decentralized finance (DeFi) ecosystem. By bridging different blockchains, wrapped tokens enable a wider range of assets to participate in DeFi, thereby increasing liquidity and capital efficiency on DeFi platforms.
Improved Liquidity and Capital Efficiency
Users can wrap assets from blockchains like Bitcoin and use them in Ethereum-based DeFi applications, taking advantage of Ethereum’s smart contracts and lending protocols. This cross-chain DeFi access not only enhances the utility of the crypto ecosystem but also paves the way for the next generation of blockchain innovation and integration.
Access to DeFi Services Across Blockchains
Wrapped tokens also provide users with the ability to access a broader range of DeFi services across different blockchain platforms. By enabling the free flow of assets across various networks, wrapped tokens empower users to leverage the unique capabilities and features of various blockchain ecosystems, further driving the growth and adoption of cross-chain DeFi.
Overall, the benefits of using wrapped tokens, such as improved liquidity, capital efficiency, and cross-chain DeFi access, are crucial in addressing the lack of blockchain interoperability and unlocking new opportunities for the crypto community.
Wrapped Token
While wrapped tokens offer significant benefits, there are also security considerations and risks associated with their use. The wrapping process relies on trusted custodians to hold the original assets, which introduces a centralized point of potential failure. This centralization risk is a concern for proponents of decentralization, as the custodian may potentially defraud users by tampering with the asset reserves, which determine the wrapped token’s value.
Wrapped Bitcoin (wBTC) and Wrapped Dogecoin (wDOGE) are two prominent examples of wrapped tokens. wBTC commands roughly 80% of the wrapped token market share, with a market capitalization of over $5.6 billion as of July 2022. The second-largest wrapped token, renBTC, is also linked to Bitcoin.
The wrapping process is designed to create a 1:1 ratio between the original token and its wrapped counterpart. For example, when Bitcoin is wrapped, the custodian holds the original BTC, and a corresponding amount of wBTC is created. This custodian model introduces custodian risk, as users must trust the custodian to accurately maintain the asset reserves.
In February 2022, a security exploit on the Wormhole bridge led to the loss of 120,000 wrapped ETH (wETH), valued at over $320 million at the time. This incident highlights the potential risks associated with centralized wrapping protocols and the importance of robust security measures to protect user funds.
Despite these security concerns, wrapped tokens continue to play a significant role in the decentralized finance (DeFi) ecosystem, providing improved liquidity and access to various blockchain services. As the adoption of wrapped tokens grows, it is crucial for users to understand the associated risks and to carefully evaluate the trustworthiness and security practices of the custodians and wrapping protocols they use.

Wrapped tokens have become an integral part of the decentralized finance (DeFi) ecosystem. By enabling the transfer of value across different blockchain networks, wrapped tokens facilitate the integration and interoperability of DeFi protocols and applications, allowing users to access a wider range of services and assets within the DeFi space.
Wrapped tokens enable assets to function on different blockchains, enhancing cross-chain asset transfer and interoperability in DeFi. These tokens can represent various assets like non-fungible tokens (NFTs), cryptocurrencies, stablecoins, and more, depending on the use case. One prominent example is Wrapped Bitcoin (wBTC) on Ethereum, which improves DeFi usability by allowing Bitcoin holders to utilize their assets in Ethereum-based DeFi applications.
The process of wrapping involves locking native coins into smart contracts and issuing equivalent wrapped tokens on another blockchain. This enables traders to use their crypto on multiple decentralized networks, promoting liquidity, interoperability, and asset functionality across different blockchain ecosystems.
| Wrapped Token | Native Asset | Blockchain |
|---|---|---|
| Wrapped Bitcoin (wBTC) | Bitcoin (BTC) | Ethereum |
| Wrapped Ether (wETH) | Ether (ETH) | Ethereum |
| Wrapped UST | TerraUSD (UST) | Ethereum, Solana, Avalanche |
| Wrapped Chainlink (wLINK) | Chainlink (LINK) | Ethereum |
Despite the advantages, wrapped tokens face regulatory concerns, centralization risks, complexity, and asset compatibility limitations. Nonetheless, they have become an increasingly popular way for traders interested in using their crypto on multiple decentralized networks, attracting more capital across the DeFi landscape.
