cbBTC is onchain.

cbBTC is an ERC20 token that is backed 1:1 by Bitcoin (BTC) held by Coinbase.

This means millions of BTC holders can now securely access DeFi apps on Base and Ethereum ecosystems—with more chains coming soon.

Great!!! Wait, could there be BTC ETFs that offer yield based on BTC held by CB for BlackRock et al - AND - could this Bitcoin be wrapped as cbBTC on base?
