Wrapped Bitcoin: The Essentials of Wrapped Tokens, WBTC, and Cross‑Chain DeFi

When working with Wrapped Bitcoin, a tokenized version of Bitcoin that lives on other blockchains such as Ethereum. Also known as WBTC, it lets Bitcoin holders tap into DeFi ecosystems without moving their BTC off‑chain.

Wrapped Bitcoin is part of the broader Wrapped Tokens, cryptographic assets that mirror a native chain's coin on a different network family. The key attribute of any wrapped token is a 1:1 reserve ratio; the supply attribute equals the amount of real Bitcoin locked in a custodial vault. This lock‑mint‑burn process is the engine that ensures trust, because every newly minted WBTC must be backed by one BTC, and every burned WBTC releases one BTC back to its owner. The underlying Bitcoin, the original proof‑of‑work network provides the value anchor, while the Cross‑Chain Assets, tokens that move value between blockchains concept enables that value to flow into smart‑contract platforms.

Three semantic connections shape the ecosystem: (1) Wrapped Bitcoin encompasses a 1:1 token supply backed by real BTC; (2) Wrapped Bitcoin requires a transparent lock‑mint‑burn mechanism to maintain parity; (3) Cross‑chain assets influence Wrapped Bitcoin’s adoption by expanding liquidity on DeFi protocols. Because the reserve ratio is visible on‑chain, governance tools can audit the vault, and DeFi apps can safely accept WBTC for lending, borrowing, or providing liquidity. This practical link between Bitcoin’s security and Ethereum’s programmability is why many traders view WBTC as a bridge rather than a replacement.
