Understanding Wrapped Tokens: Bridging the Gap Between Different Blockchains

As the world of blockchain and cryptocurrency continues to grow, we are seeing an increasing number of projects looking to connect different blockchain networks. One of the most popular solutions for this challenge is the creation of Wrapped Tokens.

Wrapped Tokens are digital assets that are backed by another asset or currency, usually from a different blockchain network. These tokens enable users to access the features and capabilities of another blockchain network without having to leave their own blockchain.

The creation of Wrapped Tokens has become an essential tool for the growth and adoption of decentralized finance (DeFi) applications, which often require interoperability between different blockchain networks. In this article, we will take a closer look at Wrapped Tokens, how they work, and their role in bridging the gap between different blockchain networks.

What are Wrapped Tokens?

Wrapped Tokens are digital assets that represent other assets, such as cryptocurrencies or tokens, from another blockchain network. These tokens are created through a process called wrapping, which involves locking the original asset on its native blockchain and issuing an equivalent amount of the wrapped token on a different blockchain.

The value of a Wrapped Token is pegged to the value of the original asset, which means that the wrapped token can be traded, exchanged, and used for transactions on a different blockchain network. This makes it possible for users to access the features and capabilities of another blockchain without having to leave their own blockchain.

The most common type of Wrapped Token is ERC-20 tokens that are wrapped on the Ethereum blockchain. These tokens are known as Wrapped Ether (WETH), Wrapped Bitcoin (WBTC), and Wrapped Zcash (WZEC), among others. These Wrapped Tokens enable users to use Bitcoin or Zcash on the Ethereum network, which is essential for DeFi applications that rely on Ethereum's smart contract capabilities.

How Do Wrapped Tokens Work?

The process of creating a Wrapped Token involves two steps: locking the original asset and issuing the wrapped token. Let's take a closer look at these steps.

Step 1: Locking the Original Asset

The first step in creating a Wrapped Token is to lock the original asset on its native blockchain. This means that the original asset is transferred to a smart contract that holds the asset in custody. The smart contract issues a corresponding amount of wrapped tokens on a different blockchain network.

For example, if someone wants to wrap Bitcoin on the Ethereum network, they would send their Bitcoin to a smart contract that holds the Bitcoin in custody. The smart contract would then issue an equivalent amount of Wrapped Bitcoin (WBTC) on the Ethereum network.

Step 2: Issuing the Wrapped Token

The second step in creating a Wrapped Token is to issue the wrapped token on a different blockchain network. This means that the wrapped token is created and made available for use on a different blockchain network.

For example, after the Bitcoin has been locked in a smart contract, the Wrapped Bitcoin (WBTC) is issued on the Ethereum network. This wrapped token can be used on the Ethereum network for transactions and other activities.

Why are Wrapped Tokens Important?

Wrapped Tokens are essential for the growth and adoption of decentralized finance (DeFi) applications, which often require interoperability between different blockchain networks. Wrapped Tokens enable users to access the features and capabilities of other blockchain networks without having to leave their own blockchain.

Another popular use case for wrapped tokens is for providing liquidity to decentralized exchanges (DEXs) such as Uniswap and SushiSwap. In a traditional centralized exchange, market makers are responsible for providing liquidity by placing buy and sell orders. However, in a DEX, liquidity providers (LPs) are responsible for providing liquidity by adding tokens to liquidity pools. LPs earn a portion of the trading fees for their contribution to the liquidity pool.

In order for LPs to provide liquidity for a token on a DEX, that token needs to be supported on the DEX's underlying blockchain. This is where wrapped tokens come into play. By wrapping a token and creating a wrapped version of it on a blockchain that is supported by a particular DEX, that token can be added to the DEX's liquidity pool and traded on the DEX.

For example, let's say there is a popular DEX that only supports tokens on the Ethereum blockchain. However, there is a new token that is not yet supported on Ethereum but is supported on another blockchain such as Binance Smart Chain (BSC). To provide liquidity for this token on the Ethereum-based DEX, the token can be wrapped as an ERC-20 token and then added to the liquidity pool on the DEX.

Overall, wrapped tokens offer a lot of potential benefits for both users and developers in the blockchain ecosystem. By enabling interoperability between different blockchain networks, they can help to create a more connected and seamless experience for users, while also allowing developers to leverage the unique features of different blockchain platforms. As blockchain technology continues to evolve, it will be exciting to see how wrapped tokens continue to play a role in shaping the future of the industry.
