On Arc · USDC · settles in under a second

Money that moves by the second.

Flux streams USDC continuously instead of in lumps — salaries, vesting and subscriptions that flow in real time, that the recipient can withdraw anytime, and that the sender can stop the moment they choose.

How it works

Four steps. No middleman, no trust required — just math on-chain.

01
Open a stream

The sender escrows USDC once and sets a window. The full amount locks in a smart contract up front.

02
It flows per second

Funds vest linearly from start to end. Halfway through, half is already the recipient's.

03
Withdraw anytime

Whatever has streamed is already theirs — pull it at second one or day thirty. No approval queue.

04
Cancel, fairly

Either side can cancel. The recipient keeps what streamed; the sender gets the rest back, in one tx.

Built for real-time money

USDC is native gas

No separate gas token to juggle — you pay and stream in the same asset.

Sub-second finality

Settlement that feels instant, the only way streaming money makes sense.

No token, no lockups

The contract holds only what you escrow. No fees, no governance, no surprises.

If it recurs, it should stream

Payroll

Salaries that pay by the second instead of once a month.

Vesting

Token & equity vesting that anyone can verify on-chain.

Subscriptions

Recurring payments that stop the instant you cancel.

Grants

Milestone funding that flows — and can be paused — transparently.
