- Prices are dollars. Arc's own coin is USDC, so a floor, a bid and a profit target are all in the same unit — and that unit does not move.
- The marketplace is OpenSea — the same Seaport order format as Ethereum, on an EVM chain with
0xwallets. - It is busy. Arc Punks traded 13,635 times in 24 hours against a 1.7 USDC floor — a lot of small, fast trades.
- No per-action fee. A bot is charged only when an order fills — 0.1%.
- No wrapping. Unlike Ethereum, where a bid needs WETH you have to acquire first, one Arc balance funds both bids and buys.
- Non-custodial. Transactions are signed in your own wallet, and cancelling an unfilled offer returns the USDC in full.
What Arc is
Arc is an EVM chain, so if you have traded on Ethereum everything will be familiar: wallets are 0x addresses, NFTs are ERC-721 or ERC-1155, and orders are signed rather than submitted as transactions.
The part that is not familiar is what you pay in. Arc's native coin is USDC — not an ERC-20 sitting on top of a gas token, but the coin the chain itself runs on. Gas is USDC, listings are USDC, and the number on a collection header is a number of dollars.
Why a dollar-priced chain is easier to trade
On every other chain a price is a quantity of something that is itself moving. A 0.5 ETH floor is one number today and a different one tomorrow without a single listing changing, and a profit target set in ETH is really a bet on two things at once — the collection, and the coin.
On Arc that second bet is gone. A 22 USDC floor is twenty-two dollars now and twenty-two dollars next month, so "buy under 15 and sell over 20" is a rule that means exactly what it says. It is a small difference that removes a conversion step from every decision you make.

A new chain is usually a quiet one, and the reason to look at Arc is that it is not. These are real collections, with the sales counts they did in a single day:

ARCadesRead on 16 September 2026: Arc Punks did 13,635 sales in twenty-four hours against a 1.7 USDC floor, Punks on Arc did 12,245, and usdc00l did 9,335. Very high turnover at a very low floor is a particular kind of market — lots of small trades, moving fast — and it is exactly the kind a bot is more useful on than a person refreshing a page.
The marketplace is OpenSea
There is no separate Arc marketplace to learn. Trading happens on OpenSea, using the same Seaport order format as Ethereum — a listing is a signed Seaport order and an offer is a signed Seaport offer, exactly as elsewhere.
That also means the fee model is OpenSea's: the buyer pays exactly the ask, and the marketplace fee and any required creator fee come out of the seller's proceeds. If you have read the Robinhood Chain guide, it is the same arrangement — worth knowing before your first sale rather than after it.
Why an Arc bid needs no wrapping
A Seaport offer cannot be denominated in a chain's native coin. On Ethereum that is why bids are WETH while listings are ETH — and why bidding there starts with acquiring a token you probably do not hold.
Arc solves that in an unusual way. Its offer token is a precompile over your native balance rather than a wrapper: the same money, exposed through an ERC-20 interface so Seaport can reference it. There is nothing to wrap — deposit() on it simply reverts — so the balance you buy with is already the balance you bid with, and a bid needs only a one-off approval.
The bots that run here
All three bot types work on Arc, and none of them charges you for the work of staying competitive:
- Bidding bots keep a collection offer live and competitive, re-pricing as the book moves — see how auto-bidding works.
- Listing bots list and re-price for you, following the floor down but never below a minimum you set, so a bot cannot sell into a collapse at any price.
- The sniper auto-buys the instant a listing lands at or under your maximum — by floor, by rarity rank or by specific traits — with budget, buy-limit and lifetime guardrails, and a paper mode for testing a rule without spending anything.
What it costs
There is no per-action fee on Arc. A bidding or listing bot costs 0.1% when an order actually fills, and nothing while it waits, re-prices or cancels — so a bot that sits on the book for a week without filling has cost you only network gas, which on Arc is paid in USDC like everything else.
The sniper is charged only on a completed buy, at 10% of the buy price, falling to 8%, 6% or 5% for Chadbots NFT holders.
FAQ
What is Arc, and where do its NFTs trade?
Arc is an EVM chain, so it behaves like Ethereum rather than Solana: wallets are 0x addresses and NFTs are ERC-721 or ERC-1155. Its NFT marketplace is OpenSea, running the same Seaport order format as Ethereum. The one thing that is genuinely different is the money: Arc's native coin is USDC, so prices there are dollars rather than a token you have to convert first.
Why are Arc prices already in dollars?
Because the chain's own gas and settlement coin is USDC. On Ethereum a 0.5 ETH floor means whatever ETH happens to be worth that day; on Arc a 22 USDC floor means twenty-two dollars, today and next month. That removes the step every other chain makes you do in your head, and it makes a profit target something you can state directly rather than approximately.
Is Arc busy enough to be worth trading?
Yes, and that is the surprising part about a chain this new. Read on 16 September 2026, Arc Punks did 13,635 sales in twenty-four hours against a 1.7 USDC floor, and Punks on Arc did 12,245. Volume that high at a floor that low is a market with a lot of small, fast trades in it — which is the kind of book automation is actually useful on.
Does Chadbot charge a per-action fee on Arc?
No. As on every EVM chain Chadbot supports, there is no per-action fee: a bidding or listing bot costs 0.1% when an order actually fills, and nothing while it waits, reprices or cancels. The sniper is charged only on a completed buy, at 10% of the buy price, falling to 8%, 6% or 5% for Chadbots NFT holders.
Do I need to wrap anything to bid on Arc?
No, and that is unusual. A Seaport offer cannot be denominated in a chain's native coin, which is why bidding on Ethereum starts with wrapping ETH into WETH. Arc exposes your native balance through an ERC-20 precompile instead, so the same balance funds both bids and buys and there is nothing to convert — only a one-off approval the first time you bid. The one thing to know is that the ERC-20 view counts in six decimals while the native coin counts in eighteen, so the raw amounts differ by a factor of a trillion. Chadbot reads the token and its decimals from the chain itself rather than from marketplace metadata, which reports the wrong one for Arc.
Can the bidding, listing and sniper bots all run on Arc?
Yes. The bidding bot keeps a collection offer live and repriced, the listing bot follows the floor down but never below a minimum you set, and the sniper buys the instant a listing lands at or under your maximum — by floor, rarity rank or traits. The same budget, buy-limit and lifetime guardrails apply as everywhere else, and paper mode lets you test a rule without spending anything.
Does Chadbot hold my funds on Arc?
No. Chadbot is non-custodial on every chain it supports. Transactions are signed in your own wallet, and an unfilled offer can be cancelled to return the USDC to you in full.
