Arc Testnet · live

Programmable money, at the speed of intent.

Arc is an open Layer-1 with USDC as native gas, sub-second finality, and EVM compatibility. This is the supercharged demo: live RPC, real wallet flows, an AI agent that can swap and send for you.

01 / Network

Built on Circle, designed for stablecoins

Open L1, EVM compatible, sub-second finality. USDC pays for gas — no native token speculation.

USDC as gas

Pay fees in the same dollar you transact. No bridging native tokens to start.

Sub-second finality

Optimised consensus targeting deterministic finality below one second.

EVM compatible

Deploy Solidity contracts unchanged. Use viem, ethers, foundry, hardhat.
