Wrapped Bitcoin (WBTC) is the first ERC20 token backed 1:1 with Bitcoin and designed to act as representation of Bitcoin on the Ethereum blockchain. The WBTC supply listed here corresponds to the amount of Bitcoin held by BitGo, the custodian responsible for minting new WBTC ERC20 tokens and guaranteeing backing of new ERC20 tokens by actual BTC.

This is the Point-in-Time (PiT) variant of WBTC Balance. PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
