Owinięty token (Wrapped)
Zasób z innego blockchainu.
Essential for 'Multi-chain' DeFi strategies. It allows assets like BTC, DOGE, or SOL to interface with Ethereum's mature smart contract ecosystem.

Imagine you have a gold coin on an island that only accepts paper bills. You give your gold coin to a trusted bank on that island, and they give you a 'Gold Certificate' bill. You can use this certificate to shop in all the local stores. If you ever want your gold back, you give the certificate back to the bank, and they return your coin. A wrapped [token](/pl/terms/token) is that 'Gold Certificate' for the digital world.
🤓 Expert Deep Dive
Wrapped tokens solve the Cross-Chain Interoperability problem. They are generally implemented via a Lock-and-Mint mechanism: 1. Locking: Native assets (e.g., BTC) are sent to a custodian or a smart contract (bridge) on the source chain. 2. Minting: An equivalent amount of wrapped tokens (e.g., WBTC) is minted on the destination chain (e.g., Ethereum). This process creates a synthetic asset that is pegged 1:1 to the original. Custodial wrapping (like WBTC) relies on a centralized entity (BitGo) to hold the collateral, introducing counterparty risk. Decentralized wrapping (like tBTC or renBTC) uses Threshold Signature Schemes (TSS) and collateralized nodes to eliminate single points of failure. The primary risk with wrapped tokens is the potential for a 'de-pegging' event if the collateral is stolen or the bridge is compromised.
