Arc USDC is worth exactly one dollar and does not trade at one dollar. This page explains why, shows what it costs right now, and compares the two ways in and the two ways out. Every number here was read off the chain.

1. What Arc USDC is

Arc is Circle's own layer 1, chain ID 5042. USDC is not a token you happen to hold on it. USDC is the money of the chain: it pays for gas, so there is no second volatile asset you have to acquire before you can move anything.

That creates the one thing that confuses every wallet and every script on first contact. Your balance has two faces. It is the native coin, carried at 18 decimals like ether, and it is also an ERC20 at 0x3600000000000000000000000000000000000000, carried at 6 decimals like USDC everywhere else. These are not two balances you can hold different amounts of. They are one balance shown two ways, and the two readings differ by exactly a factor of a trillion.

Because gas is denominated in a dollar, the cost of using Arc is legible in a way it is not elsewhere. At the current base fee an ordinary transfer costs about 0.0004 USDC, which is four hundredths of a cent.

2. Why it costs more than a dollar

Arc USDC redeems one for one against USDC on Ethereum, Base and every other chain Circle supports, through Circle's own CCTP. Burn a unit on one side, mint a unit on the other. By construction it is worth a dollar and there is no peg here to break.

It changes hands above a dollar anyway. The reason is not the asset, it is the queue. More people want to be holding USDC on Arc than are willing to carry theirs over and hand it to someone else, and the premium is the price of that willingness. It is a fee for immediacy, paid to whoever already did the slow part.

One thing the premium is not is a transfer limit. Moving USDC into Arc has never been capped. Moving it out is capped at 100,000 USDC per CCTP message, a ceiling almost nobody reaches. This is worth stating plainly because the widely repeated figure is 1 USDC per message, which was true early on and is no longer true; the current value is readable at any time from the batch contract's perMessageLimit().

3. Two ways in

Bridge it yourself. You need USDC on Base or another CCTP chain. You burn on that side, Circle attests, and it mints to your address on Arc. You pay no premium at all, because nobody is selling you anything. What you spend is time and a fee. This site does not offer the inbound leg; use Circle's own bridge for it.

Buy it from someone who already has it. Instant, and you pay whatever they ask. On this site the seller sets the price and their inventory is already deposited, so the delivery is not a promise: it is a balance sitting in a contract before you pay anything.

Which of the two is cheaper depends entirely on the premium, which is the figure at the top of this page. There is no general answer, only today's.

4. Two ways out, and where people lose money

The same two routes run in reverse, and the choice is worth more here than it is on the way in.

Bridging out returns exactly one for one. That is the whole point of CCTP and it is completely reliable. It is also, whenever the market pays a premium, the more expensive door: one for one means you receive the dollar and hand the premium to nobody. If Arc USDC is trading at 1.20 and you bridge 1,000 out, you have declined roughly 200 dollars that somebody was willing to pay you.

Selling collects that premium instead. You deposit into a contract, name your price, and keep the ability to withdraw anything that has not sold. The trade is that you wait for a buyer, where the bridge waits for nobody.

The honest summary: bridge out when you need the money now and the premium is thin, sell when the premium is not thin. Check the number above before you decide, because it is the only input that matters.

5. What each route costs

Bridge in (Circle, not here)none0Circle's attestation
Buy hereyou pay it2%nobody, inventory is deposited
Bridge outnone, and you forgo it2%Circle's attestation
Sell hereyou collect it2%a buyer

The 2% is this service's fee and it is capped in the contracts at 5%, a constant no key can raise. Circle charges nothing for CCTP itself; the chain charges the gas quoted in section 1.

6. Where these numbers come from

Everything above is a chain read, not a claim, and the build refuses to publish this page if any of it stops matching.

The chain ID, the ERC20 address and its decimals come from Arc itself. The per-message ceiling is perMessageLimit() on the batch contract at 0x477cecd9cad406c58a76dd048393b680be29ecfd, which forwards to Circle's own token minter. The fee and its immutable ceiling are feeBps() and MAX_FEE_BPS() on the escrow at 0x8eb82c4ed189ed310f3c0a4de44a68b82a05eb7e. The premium at the top of the page is read live from that escrow's open offers each time the page loads.

If you want to check any of it yourself rather than take our word, every address above is a public contract and the source is published.
