fomo on Arc
Circle's new layer-1 on the fomo app: the launch-day burst, what a trade costs, and the one deposit check fomo tells you to make before withdrawing to Arc.
Arc is Circle's layer-1 blockchain, where network fees are paid in USDC. Circle's September 16, 2026 mainnet release named fomo, Aero and Uniswap as Arc's day-one trading apps. On the fomo app an Arc trade costs 0.50% plus the network fee; Arc's fomo fees were $414K on launch day, then $33K in all of October (DefiLlama). In the 30 days to November 8, 2026, Arc accounted for 0.1% of fomo's fees ($13.9K of $10.3M, DefiLlama).

What Arc is
Circle, the company behind the USDC stablecoin, launched Arc’s public mainnet on September 16, 2026, describing it as “an open Layer 1 blockchain purpose-built for financial markets, real-time money movement, and agentic economic activity.” Arc’s own docs say it “denominates all transaction fees in USDC, the native gas token”, with a design target of about $0.001 for a simple token transfer under normal load. That target is Arc’s, not a fomo price.
Circle’s release also said: “Aero, fomo, and Uniswap anchor Arc’s day one trading infrastructure.” For fomo, Arc is one of seven EVM networks on your single EVM address, and fomo names explorer.arc.io as its explorer.
Funding, withdrawing and trading on Arc
- Deposits: USDC on Arc. fomo publishes no Arc minimum; the deposit screen shows it.
- Withdrawals: USDC on Arc, with a warning worth repeating: “check first that the receiving wallet or exchange accepts USDC on that network.” Arc only launched in September 2026, so do not assume a wallet or exchange supports it.
- Cost: 0.50% per trade, 0.45% with a referral code, plus the network fee, which you pay. The table above computes fomo’s part from its published schedule.
The launch-day burst
DefiLlama’s fee data for fomo on Arc starts on September 15, 2026, the day before Circle’s announcement. What followed is the sharpest launch curve of any fomo chain, from DefiLlama’s daily series (read November 10, 2026):
| Period | fomo fees on Arc |
|---|---|
| September 16, 2026 (launch day) | $414K |
| September 17 | $66K |
| September 18 | $25K |
| All of September | $625K |
| All of October | $33K |
Launch day alone was two thirds of Arc’s September total. October came in 95% below September, the steepest fall of any fomo chain. All-time, DefiLlama puts fomo’s Arc fees at $659K. Referrers received 15.8% of Arc’s September fees, out of what traders paid.
None of this says anything about Arc as a network, only about how much fomo’s users traded there. Arc’s current share of fomo’s fees is in the bars above.

Questions people ask
What is the minimum deposit on Arc for fomo?
fomo has not published it. Its help centre gives 0.50 for Base, BNB Chain, Monad and Robinhood Chain and none for Solana, and says the deposit screen shows the minimum when you select a network. Check it there before sending.
Can I withdraw from fomo to an exchange on Arc?
Only if the exchange accepts USDC on Arc. fomo's help centre says to check first that the receiving wallet or exchange supports USDC on Arc; sending on a network the receiver does not support can lose the funds.
