Arc chain alpha terminal, priced in USDC

Arc is Circle's layer 1 where USDC itself is the gas token, so every position, fee and PnL on this chain is already in dollars. There is no wrapped native token: the terminal trades the USDC ERC-20 directly through Uniswap's SwapRouter02 on Arc with exact-amount approvals.

The scanner follows the Uniswap V3 factory on Arc for new USDC-quoted pools, backfills liquidity and volume from DexScreener, and the Solo Agent sizes entries and daily loss caps in USDC instead of ETH.

Frequently asked about Arc

Why are Arc trades priced in USDC instead of ETH?: On Arc the gas token is USDC (chain id 5042), so there is no ETH to hold. The terminal shows quick-buy presets, agent trade sizes and daily loss caps in USDC, and your balance in the wallet is the same number whether you read it as gas or as the USDC ERC-20 at 0x3600...0000.
Do Arc USDC buys need a token approval?: Yes, unlike ETH on Base or Robinhood Chain. Arc has no wrapped native token, so the router pulls USDC via a normal ERC-20 allowance. The terminal requests the exact amount of each trade, never an unlimited approval.
Which DEX does the terminal use on Arc?: Uniswap's official deployment on Arc: the V3 SwapRouter02 for execution and QuoterV2 for quotes, verified against the V3 factory on-chain. Discovery also lists V4 pools from DexScreener, but execution today is on V3 pools.
