How It Works

Three steps from sign-up to sending payroll.

01

Create your account

Sign up in seconds. We instantly provision a developer-controlled SCA wallet on Arc Testnet and every supported source chain — no seed phrases, no MetaMask required.

02

Fund from any chain

Deposit USDC from Ethereum Sepolia, Base Sepolia, Arbitrum Sepolia, or Polygon Amoy. Circle CCTP V2 burns it on the source chain and mints it directly to your Arc wallet in ~2–3 minutes.

03

Run payroll or send payments

Add employees with wallet addresses and salaries, then hit Run Payroll. Or send one-off payments to any Arc Testnet address instantly. All transactions are on-chain and auditable.
