What this feed is
How many USD Coin (USDC) tokens exist on OP Mainnet right now, counted by the token contract itself.
Methodology
Written by the provider.
The answer of totalSupply() on the USDC contract 0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85 on OP Mainnet (chain 10), read from the chain's own public RPC endpoint https://mainnet.optimism.io at the latest block and scaled from the token's 6 decimals. It is the supply on this chain only, not the issuer's total across chains, and it says nothing about reserves. Native USDC only; bridged USDC.e is a separate token. Anyone can make the same call and compare.
