WBTC, the tokenized version of Bitcoin, is expanding its presence across multiple blockchain networks to enhance cross-chain functionality and support wider Bitcoin adoption in the DeFi ecosystem. This strategic move aims to leverage WBTC's existing market cap of approximately $14.5 billion and its deep liquidity in DeFi markets. Launched in early 2019, WBTC allows Bitcoin holders to engage with decentralized applications through a fully custodied, verifiable 1:1 token. The expansion is expected to facilitate broader use of Bitcoin in decentralized finance, further solidifying WBTC's role as a multichain standard.
