Arc Mainnet, T-minus 11: the four-tenths-of-a-cent dollar network

With eleven days to mainnet, we are examining the design decision everything else on Arc depends on.

What it means

Every blockchain before Arc made you pay fees in its own volatile token, a structure that works fine for speculation and terribly for commerce. A payments processor cannot budget in an asset that moves 8% overnight; a payroll platform cannot quote costs it does not know. Arc's answer is almost anticlimactic: fees are USDC. A dollar network where the tolls are in dollars.

The consequences compound. For users, there is no second token to buy and no way to be stranded holding money you cannot move. For businesses, cost forecasting becomes arithmetic — a million transactions at $0.004 is $4,000, knowable in advance. And for the network itself, it removes the usual reason a chain needs a tradable token at all, which is worth remembering when evaluating ARC token speculation: Arc launches without one by design, not by delay.

There is a second half to the bargain: what the fraction of a cent buys. Arc settles with finality — irreversibly — in under one second. Cards authorise in seconds but settle in days and can reverse; wires take a business day. Sub-second final settlement for sub-cent fees is the combination the validator cohort of payment giants signed up to operate.

The testnet has been rehearsing this at scale: roughly 13.5 million transactions in a single mid-August week.
