Arc's native coin is USDC, and it has 18 decimals where the EVM can see it:
eth_getBalance, msg.value and every native amount in these contracts. The ERC-20 predeploy for the same balance presents 6 decimals. The two are one balance behind two interfaces, and mixing them misprices a figure by 1e12.
