What computation costs on Arc, in dollars, measured on chain.

Arc's gas token is USDC, carried at the EVM level with 18 decimals. So gasUsed × tx.gasprice is a dollar amount, directly — there is no price feed anywhere in that expression.

On a chain whose gas token floats, a contract that wants to know what it just cost in dollars needs an oracle, and inherits its staleness and its failure modes. Here the unit of gas is the unit of account. Every figure below was read from the contract just now, in your browser.

baseline is the measurement harness itself — two gasleft() reads with nothing between them. It is published rather than subtracted, so you can subtract it yourself.
