What this feed is
How many USD Coin (USDC) tokens exist on Arbitrum One right now, counted by the token contract itself.
Methodology
Written by the provider.
The answer of totalSupply() on the USDC contract 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbitrum One (chain 42161), read from the chain's own public RPC endpoint https://arb1.arbitrum.io/rpc 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.
