What Are Wrapped Tokens? wBTC and Beyond
Last Updated: June 15, 2026
Blockchains do not natively communicate with one another. Bitcoin cannot run smart contracts on Ethereum, and ETH cannot be used inside a Solana DeFi protocol without bridging. Wrapped tokens solve this problem by creating a tokenized, 1:1-pegged representation of an asset on a foreign blockchain. The most well-known example is Wrapped Bitcoin (wBTC), an ERC-20 token backed by real BTC held in custody. Understanding wrapped tokens is essential for anyone active in spot trading or exploring broader DeFi strategies on a crypto exchange.
How Wrapped Tokens Work
The wrapping process involves three parties in the most common custodial model: a user, a merchant, and a custodian.
- A user sends native BTC to an authorized merchant.
- The merchant instructs the custodian (for wBTC, primarily BitGo) to mint an equivalent amount of wBTC on Ethereum.
- The newly minted wBTC is delivered to the user's Ethereum wallet.
The BTC is locked in reserve for as long as the wBTC exists. When the user wants their BTC back, they burn the wBTC through the merchant, and the custodian releases the underlying Bitcoin. This full-reserve model ensures the peg holds at 1:1. The entire flow is tracked on-chain via a publicly auditable dashboard maintained by the wBTC DAO, so anyone can verify that circulating supply matches reserves at any given moment.
Non-custodial alternatives use smart contracts or decentralized liquidity networks instead of a central custodian. These eliminate single-point-of-failure risk but introduce smart contract risk and sometimes require over-collateralization to maintain the peg during volatile market conditions.
Major Wrapped Tokens and What They Enable
Beyond wBTC, dozens of wrapped assets circulate across different ecosystems. Here is a comparison of the most widely used wrapped tokens as of mid-2026:
| Token | Underlying Asset | Host Blockchain | Custody Model |
|---|---|---|---|
| wBTC | Bitcoin (BTC) | Ethereum | Centralized (BitGo) |
| WETH | Ether (ETH) | Ethereum | Smart contract |
| wSOL | Solana (SOL) | Ethereum / BNB Chain | Bridge protocol |
| BTCB | Bitcoin (BTC) | BNB Chain | Centralized (Binance) |
| wAVAX | Avalanche (AVAX) | Ethereum | Smart contract |
WETH is a special case: Ether itself predates the ERC-20 standard, so it must be "wrapped" into a compliant form to interact with most Ethereum DeFi applications. Wrapping ETH into WETH costs only a small gas fee and can be done in seconds through any compatible wallet or dApp.
The significance of wrapped tokens extends beyond convenience. They unlock Bitcoin's enormous capital for use in lending protocols, liquidity pools, and yield strategies. As of early 2026, over 150,000 wBTC remain in circulation, representing billions of dollars of BTC actively deployed in Ethereum-based DeFi rather than sitting idle.
Risks to Understand Before Using Wrapped Tokens
Wrapped tokens carry risks that the underlying native asset does not:
- Custodial risk: Centralized custodians can be hacked, go insolvent, or become subject to regulatory action. If the custodian fails, wrapped token holders may not be able to redeem at par.
- Smart contract risk: Decentralized wrappers rely on audited code, but no audit is a guarantee. Bugs or exploits in bridge contracts have resulted in some of the largest losses in DeFi history.
- De-pegging risk: Under extreme market stress or if a custodian is suspected of insolvency, wrapped tokens can trade below their peg. In liquid markets this discount is usually temporary, but it can be significant during a crisis.
- Bridge complexity: Moving assets across chains requires multiple steps, each carrying transaction fees and potential points of failure.
Understanding these risks does not mean avoiding wrapped tokens; it means sizing positions appropriately and choosing wrapping providers with strong audit histories and transparent reserve proofs.
Wrapped Tokens and EVEDEX
EVEDEX does not accept wrapped tokens as collateral and does not list them as trading pairs. It is a hybrid exchange for perpetual futures: orders are matched off-chain and settled on-chain on Arbitrum L2, and margin is posted only in USDT. If you hold wBTC and want a leveraged bitcoin position, the wBTC has to be converted to USDT first, on another venue or through the coin exchange in the EVEDEX deposit window, before it can back a BTC-USD position for leverage trading in its crypto futures markets.
The BTC-USD and ETH-USD perpetuals track the prices of bitcoin and ether, so they give the same price exposure as wBTC or WETH without holding either token. There is no token delivery: a perpetual pays or receives funding, calculated every 8 hours and charged hourly, and under cross margin a leveraged position can be liquidated.
Wrapped tokens stay useful for spot trading and DeFi activity on other platforms, where they move between chains and protocols. EVEDEX has no spot market and no token wallet, so it cannot hold your wBTC or WETH; its role is the derivatives side, such as a short BTC-USD or ETH-USD perpetual that hedges wrapped holdings kept in your own wallet.
