Properties

Circulating Supply

The number of wrapped asset units in possession of customers. It excludes units pre-minted and held in abeyance to quickly serve wrapping customers. Circulating supply is the most appropriate input to determine the market capitalization of a wrapped asset.

Total Supply

The total number of wrapped asset units that have been minted and exist on-chain.

Conversion Rate

The number of underlying staked units that can be exchanged for 1 wrapped asset (e.g., the number of ETH2 units per 1 cbETH unit).

Implied APY

Current annualized percentage yield earned as the net rewards by the staked ETH underlying cbETH. This estimate is based on the past 7 days of staking performance and is updated daily. For more details, refer to the “rate calculation” section of the cbETH whitepaper.
