Money that moves
like a current.
Rill streams USDC by the second on Arc. Lock it once and it flows to the recipient continuously, payroll, vesting, and grants that arrive like water, not in lump sums.
A deposit that drains at the speed of the work.
Lock USDC once
Open a stream with a recipient, an amount, and a window. The deposit is held by the StreamPay contract.
It vests per second
The balance flows to the recipient linearly, every second, computed exactly on-chain with no rounding dust.
Withdraw or cancel
The recipient pulls whatever has vested at any time. Either party can cancel and split the balance fairly.
Money that should move continuously.
Payroll
Pay contributors continuously. They draw earnings whenever they want instead of waiting for a pay cycle.
Vesting
Token or stablecoin vesting that unlocks by the second, cancellable if someone leaves, with no cliff cliffhangers.
Grants
Fund builders over a period and keep the runway visible. Stop the stream if a milestone slips.
Open a real stream on Arc Testnet.

Arc testnet (chain 5042002), where USDC is the native asset. The StreamPay contract is live and settling real streams.
The vested-but-unwithdrawn amount goes to the recipient and the remainder returns to the sender. Either party can cancel.
Yes. The contract uses a deposit/start/stop model and computes the streamed amount exactly, so no dust is stranded by per-second rounding.
No. USDC is native on Arc, so a stream is a single asset end to end, no wrapping, no bridge, no second token for gas.
