What this feed is
How many Coinbase Wrapped BTC (cbBTC) tokens exist on Base right now, counted by the token contract itself.
Methodology
Written by the provider.
The answer of totalSupply() on the cbBTC contract 0xcbB7C0000aB88B473b1f5aFd9ef808440eed33Bf on Base (chain 8453), read from the chain's own public RPC endpoint https://mainnet.base.org at the latest block and scaled from the token's 8 decimals. It is the supply on this chain only, not the issuer's total across chains, and it says nothing about reserves. Anyone can make the same call and compare.
