Description: The article presents the overview of wrapped tokens: what they are, how they work, their pros and cons, their use cases, and the influence on the whole industry.
In the fast and innovative world of blockchain and decentralized finance (DeFi), network interoperability is a clear sticking point. That's where token wrapping comes in. These tokens are actually wrapped so as to facilitate the peaceful transport of digital assets across chains, without compromise on the intrinsic value of digital assets.
If you’re a crypto beginner looking to get to grips with more advanced DeFi processes, this overview can help you get to grips with what wrapped Bitcoin is, how it works, and why it should be considered a cornerstone in adding a new dimension to blockchain flexibility and liquidity.
So, what does wrapped mean in crypto? Wrapped tokens are digital representations of cryptocurrencies that live on a blockchain other than their original chain. They enable digital assets to be utilized on several blockchain systems, increasing liquidity and usability.
For example, a Wrapped Bitcoin (WBTC) is a tokenized version of the original Bitcoin (BTC). It runs on the Ethereum network. Each WBTC is collateralized 1:1 with Bitcoin stored in the reserves of a reliable custodian. Under this arrangement, Bitcoin holders can interact with decentralized applications (dApps), decentralized exchanges (DEXs), and other services that would not otherwise be accessible by Bitcoin.
Wrapped crypto solves a long-standing issue of the crypto industry: lack of interoperability between blockchains. Because the majority of cryptocurrencies are constrained to their home networks, they cannot natively communicate with other networks. Users can gain access to new blockchain environments that open up participation for decentralized finance (DeFi) and cross-chain innovation by potentially wrapping these assets.
Wrapped tokens were developed to address one of the biggest constraints of blockchain technology: the fact that different blockchains cannot transfer data and assets to each other.
Wrapped crypto facilitates cross-chain compatibility, where one blockchain is used to represent and transfer assets from another blockchain, like Bitcoin on another chain such as Ethereum in the form of a token (like WBTC). This interoperability ensures even more people have access to DeFi across the market. Wrapped tokens make it so those native tokens can access a variety of decentralized finance protocols, things like lending, borrowing and yield farming, that they otherwise couldn’t.
Wrapped tokens mean more liquidity around the blockchains. Through asset wrapping, users can also help to move idle capital between platforms, since doing so is as easy as sending a single transaction. This also enables new use cases: wrapped tokens can be included in smart contracts and automated market makers (AMMs) and decentralized exchanges (DEXs), offering additional services for assets beyond their home chain.
Wrapped crypto is a blockchain-native version of on-blockchain assets. This category of products operates from smart contracts, custodian activity, and decentralized governance, in which the two model SPDUs are defined as follows. Here's how it works:
If someone wants to wrap a token, say from Bitcoin into Wrapped Bitcoin (WBTC), they send it to a custodian (which can be a centralized provider, a multisig wallet, or a smart contract).
In return the custodian mints an equivalent value of the wrapped token on the destination chain (e.g. Ethereum). The wrapped token is the value of the underlying asset in a different blockchain universe.
For wrapped tokens, the ratio is typically 1:1. This peg is backed by a burn and mint system. When the user converts back to the original asset, the wrapped token is burned and the custodian does an issuance (release) of the native currency for that amount. This preserves the full supply of wrapped tokens in parity with native tokens held in storage, holds the peg, and prevents inflation or double issuance.
In some more decentralized systems like WBTC or tBTC, wrapping is managed by a Decentralized Autonomous Organization (DAO). These DAOs each consist of a number of members or protocols that, as a whole, are designed to:
DAO governance decreases dependence on one individual and introduces trust and transparency into the wrapped token space.
Wrapped tokens are cryptocurrencies that are backed by other digital assets on a different blockchain and can be used on a new network. Like Wrapped Bitcoin (WBTC), which allows you to use BTC in the Ethereum ecosystem, Wrapped Etherreum (WETH) is a tokenized version of Ether used throughout Ethereum’s ecosystem.
Here are some major examples:

While wrapping tokens was initially conceived as a way to bridge assets like Bitcoin onto Ethereum, the idea has come a long way. Today, wrapping tech is enabling radical new frontiers across DeFi and beyond, such as NFTs, real-world assets-as-tokens, and frictionless cross-chain interoperability.
Wrapped NFTs are digital representations of non-fungible tokens that can be transferred or traded on alternative blockchain networks or used in decentralized finance (DeFi) applications. For example: An NFT, minted back in the day on the Ethereum network, can be wrapped up and used within another network such as Polygon or Solana.
There’s also the ‘wrapped token,’ which represents assets of the real world such as gold, land, stock, or government bonds in the form of a token. For example: A gold bar can sit in a vault, and a wrapped token like PAXG (Paxos Gold) will denote ownership of that physical asset.
Wrapped coins offer a way to play with assets from one blockchain on another, extending their usefulness, but they also carry risks like centralization and security holes. And whilst these present cross-chain interoperability and liquidity, to access the network you have to trust the custodians and the smart contracts – both of which can be a single point of failure.
Enhanced Accessibility
Wrapped non-native assets enable users to interact with supported wallets, exchanges, and dApps more seamlessly without the burden of constantly exchanging or bridging tokens. They also allow the tokenization and handling of real-world assets (e.g., fiat money, commodities) inside the blockchain world.
Because they fit right in with DeFi platforms, wrapped tokens grant access to a host of services such as yield farming, staking, lending, borrowing, and token swaps. This optionality gives buyers power to browse other options and choose which is best for them.
Improved Liquidity
For illiquid assets, wrapped coins offer a solution, as they can be traded on mainstream DEXs like Uniswap or Curve. Their presence on these platforms raises the profile and facilitates broader engagement across the crypto sphere.
Increased platform coverage brings in more users, traders, and investors, who can increase the liquidity pool and thus increase the market value of the native asset.
Cross-Chain Interoperability
Wrapped tokens are bridges between blockchains, and the best of what each has to offer can be harnessed to enhance user experience. This cross-chain capability enables users to select networks that have lower fees or quicker transaction times to then better support their DeFi actions, like trades, staking, and liquidity sunset providing.
For example, Wrapped Bitcoin (WBTC) bridges the value of Bitcoin onto the Ethereum blockchain, giving users access to Ethereum dApps and protocols but keeping the price consistent with BTC.
Centralization and Custodial Risk
The main limitation of wrapped tokens is the dependency on centralized custodians for wrapping and unwrapping. These third parties are required to be trusted by the users to hold their original assets until redemption and therefore are exposed to loss or mismanagement.
If there were to be poor asset management, it is possible that custodians do not have the assets to unwind users, and you won’t be able to unwrap when your tokens are redeemed for them.
Smart Contract Vulnerabilities
Wrapping is automated and enforced using smart contracts. While these contracts are usually transparentand efficient, they are prone to bugs or security holes. Faulty smart contract code can be exploited by bad actors, resulting in things like theft, incorrect token issuance, or the protocol being derailed.
Technical Barriers for New Users
It is also deceptively simple; however, unwrapping and wrapping crypto can be a bit of a head-scratcher for beginners.
This complexity could make wrapped tokens unappealing to the average user, which would restrict the widespread usage of wrapped tokens as entry-level financial instruments in the crypto economy.
Here’s a rather simple comparison between Wrapped Tokens vs Native Tokens that can help to understand the basic difference:
| Feature | Native Tokens | Wrapped Tokens |
|---|---|---|
| Blockchain Origin | Exist on own chain or platform | Generated on a different blockchain than the token it represents |
| Interoperability | Limited to native chain | High – can be used for multiple chains |
| Liquidity Access | Limited to native ecosystem | Increases liquidity for DeFi protocols and chains |
| Custody | Held by users or wallets | 1:1 collateralized and served by a custodian or smart contract |
| Conversion Process | Direct use without wrapping/unwrapping | Need mint and burn function |
| Transparency & Trust | Transparent by concept of the native chain | Reliance upon the trust/security of the custodian/wrapping protocol |
| Governance | Core protocol managed, miners/stakers used as enforcers | Tokens that are frequently managed or controlled by DAOs, or through custodial agreements |
| Use Cases | Transactions, staking, gas fees, native apps | DeFi across chains, DEX trading, lending, collateralization |
| Examples | BTC, ETH, SOL | WBTC, WETH, etc. |
A native token is the heart and soul of its blockchain, the main currency used for gas fees, governance, and direct interaction with native apps. Wrapped tokens increase the usability of those native assets by allowing users to access them on other blockchains, and especially in DeFi, enhancing interoperability, ease of liquidity access, and cross-chain operability.
The largest wrapped token is Wrapped Bitcoin (WBTC), supported by a consortium of trusty custodians and governed by a DAO. But as the ecosystem has expanded, a number of other wrapped tokens have debuted on different chains and use cases, bringing with them serious questions of safety.

Getting them, users should consider custodial risks, smart contract risks, peg stability, and DAO governance and transparency as the main issues with wrapped tokens.
WBTC has raised the bar, but not all wrapped tokens are made equal. Wrapped tokens other than WBTC can be secure, but only if they’re supported by transparent custody, strong governance, and fully audited technology. As always in DeFi: trust, but verify.
So, here we considered what wrapped tokens are. These assets are quite literally game changers for what digital money can do and a bridge between blockchain worlds that would otherwise exist in walled-off districts. They enhance interoperability and liquidity across networks so users can make the most of their holdings. Tokens such as WBTC and WETH enable users to employ assets like Bitcoin on DeFi platforms native to Ethereum without having to sell or convert them beforehand.
If you’re interested in participating in decentralized loans, trading, yield farming, or more, wrapped tokens are a smart, multifaceted option. This will become even more important as DeFi grows and cross-chain activity becomes more important in facilitating wider DeFi usage. Knowledge of how wrapped tokens work and how to trade with them can yield new opportunities in an expanding crypto world.
