Subscriptions that collect themselves.
A $5 monthly plan cannot survive where collecting it costs more than it earns. Here a charge costs the rounding error below — so a subscription can pull its own money, every period, with nobody clicking anything.
One charge — · a year of monthly billing — · gas paid in USDC
Send money with something to say
A payment carries a note on-chain, so the receipt explains itself later. Or turn it into a pay-link: the other side opens it, sees exactly what is being asked for, and pays in one tap.
Send a payment
One transaction, up to twenty wallets
Equal shares, a single confirmation, and a separate on-chain receipt for every recipient. Rounding dust comes back to you rather than being stranded in the contract.
Split a payment
Payments you can take back
Inspired by Miden's P2IDR notes. The recipient can claim at any moment; if they never do, the money returns to you once the window closes. The cure for sending to the wrong address.
Send a recallable payment
Your recallable payments
Connect & load — outgoing payments show a recall countdown, incoming ones a claim button.
One transaction, two chains
A message leaves Arc through the Chainlink CCIP router, crosses a live lane, and runs code in a contract on the far side — where it is stored and emits an event you can read back below. The fee is paid in USDC, like everything else here.
Send a message across chains
Powered by Chainlink CCIP. Your message leaves Arc Testnet and is delivered to Ethereum Sepolia — one of the few live cross-chain lanes on Arc. The fee is paid in USDC, like everything else here.
Messages on —
Read straight from your receiver contract — — every message that crossed from Arc and actually landed here.
Send a cross-chain message, wait a few minutes, then load — this proves it arrived and ran code on the other chain.
How this works
→ Chainlink routes the message over the live Arc → Sepolia lane
→ It lands on Ethereum Sepolia and runs your receiver contract
→ The contract stores the message and emits an event
→ One transaction, two chains, real app-to-app messaging
A worker that bills for you
A tiny on-chain agent with its own wallet, living in this page. While it is online it watches the subscription contract and charges every due subscription by itself — no MetaMask prompt, no click, no human. It pays only transaction fees; the subscription money always moves subscriber → merchant directly and never touches the agent.
Every payment, straight from the chain
Read out of the contract's own events and filtered to your address — nothing here comes from a server that could be wrong.
Your receipts
Connect your wallet and load — every Pay on Arc payment you sent or received, straight from the chain.
Recurring payments, settled on-chain
No money leaves your wallet up front. You approve USDC once, and each period is pulled only when it comes due — by the merchant, by you, or by the billing agent. Cancel in one transaction, any time, from either side.

A treasury that rebalances itself
It holds USDC and EURC and tries to keep a fixed split of value between them. Every EUR/USD tick moves that split, so the agent reads the Pyth feed and — once drift breaks the band — pays any keeper a bonus to settle it back on-chain.
