We all like to drive but sometimes it's interesting to see how the engine works. Found this article interesting
https://www.arc.network/blog/building-with-usdc-on-arc-one-token-two-interfaces
Relevant to X402 ?
USDC as the native gas token
Lives in each account’s native balance field.
Uses 18 decimals internally for EVM precision and gas metering.
Queried with calls like publicClient.getBalance(address).
USDC as the ERC-20 contract
Available at contract address
0x3600000000000000000000000000000000000000.
Exposes standard ERC-20 functions like balanceOf, transfer, and approve.
Uses 6 decimals, consistent with USDC’s behavior on other chains.
Queried through SDKs or libraries expecting an ERC-20 interface.
