Over $6 billion worth of Bitcoin has been tokenized on Ethereum as Wrapped BTC (WBTC), representing 1% of Bitcoin's circulating supply. This milestone was acknowledged by Kia Mosayeri, Product Manager at BitGo, the custodian of the Wrapped Bitcoin protocol.
The Rise of WBTC: A $6.2 Billion Milestone
The Wrapped Bitcoin protocol launched WBTC in January 2019 as an ERC-20 token backed 1:1 by Bitcoin. According to Etherscan data:
- 187,610 BTC currently tokenized as WBTC
- $6.18 billion fully diluted market cap
- Represents 1% of Bitcoin's 18.73 million circulating supply
