What is Arc?
The essentials, in plain English.
What makes Arc different from other chains? ▾
Arc uses USDC as its native gas token. On most EVM chains you pay fees in a volatile coin (ETH, BNB, etc.). On Arc, gas is paid in USDC — a dollar-backed stablecoin — so transaction costs are predictable and stable. It also delivers sub-second finality, meaning blocks are confirmed in under a second.
Why is USDC-native gas a big deal? ▾
Developers can let users pay fees directly in the stablecoin they already hold — no need to juggle a second "gas coin." For apps (payments, DeFi, gaming), this removes a major UX and treasury headache: predictable costs, no volatility on fees.
What chain ID / RPC should I use? ▾
Mainnet chain ID is 5042002. RPC endpoints and network config will be confirmed here the moment genesis lands — this dashboard detects mainnet automatically and displays the live endpoint.
When exactly does it launch? ▾
Genesis is scheduled for September 16, 2026 at 6:00 PM GMT. The countdown above converts to your local time automatically.
