What Are Wrapped Tokens? wBTC and Beyond

Last Updated: June 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.

1. A user sends native BTC to an authorized merchant.
2. The merchant instructs the custodian (for wBTC, primarily BitGo) to mint an equivalent amount of wBTC on Ethereum.
3. 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.

Trading Wrapped Tokens on EVEDEX

EVEDEX supports several major wrapped tokens as collateral and trading pairs, giving traders flexible access to cross-chain liquidity without leaving the platform. If you hold wBTC and want to open a position without first unwrapping back to native Bitcoin, you can use it directly as margin for leverage trading or trade it against other assets in crypto futures markets.

When trading wrapped assets on EVEDEX, the platform displays the underlying asset price feed, so wBTC tracks Bitcoin's price directly. This means you capture the same price exposure as native BTC while keeping your capital inside the Ethereum ecosystem and accessible to the full range of EVEDEX instruments.

For traders who regularly move between spot and derivatives positions, wrapped tokens reduce friction considerably. Rather than bridging back to native assets before each trade, you can keep wBTC or WETH in your EVEDEX wallet and shift between strategies as market conditions change. The result is a more capital-efficient workflow, especially for active traders managing multiple open positions across different time horizons.
