An open settlement primitive for agents, and the autonomous treasury agent that's already its first live user.
Treasury payments run on trust, not proof.
No custody without a chaperone
An agent that's supposed to act alone still needs a human to hold the keys or approve the transfer.
No provable record
A wrong payment is a support ticket and a spreadsheet, not a transaction anyone outside the company can check.
No settlement fast enough to watch closely
If checking a balance costs almost as much as the payment, nobody checks it often enough to catch problems early.
A ledger-writing machine, not a script with a cron job.
Arcurrent reads what's owed, decides from the real treasury balance, the due date, and a reserve floor, and settles by creating and releasing a mandate on MandateEscrow, an open primitive any address can fund, fulfill, or read.
Nothing here is simulated. Every figure on the next slide is a real transaction hash on Arc mainnet, not a mock.
Two real settlements, five real transactions, on Arc mainnet.
Captured 2026‑09‑22, real mainnet USDC. Current counts are on the live dashboard and Mandates table.
Two obligations, $0.05 and $0.03 USDC, settled by creating and releasing mandates on MandateEscrow · not a pre-funded pool, straight from the treasury wallet's own balance.
Fulfiller reputation after both: 2 completed, 0 refunded, $0.08 volume settled · read live from the contract, not this project's database.
Bonus proof, captured 2026‑09‑23: the one capability the two settlements above don't show, since both paid a single destination.
Four real primitives, one decision loop.
Developer-Controlled Wallets
The treasury and liquidity wallets are Circle-custodied. No private key lives in this codebase.
MandateEscrow
A permissionless contract on Arc mainnet: fund a mandate for anyone, prove fulfillment, release atomically, split payouts, refund on deadline. Reputation updates on-chain. Not project-owned · this agent is just its first live caller.
App Kit · Bridge (CCTP)
Circle's App Kit SDK, kit.bridge(): cross-chain USDC top-ups when a payment would breach the reserve floor. Proven on testnet; disabled on mainnet until a Live-environment source wallet is funded.
x402 nanopayments
The agent pays a sub-cent fee for the live FX rate it needs before acting on a foreign bill.
This is the pattern Circle's Agent Stack formalizes: wallets, an onchain program, cross-chain liquidity and a machine-payable service, wired into one loop. Built directly against those primitives rather than a starter kit, since the loop itself is the product.
Arcurrent: current, twice.
Gas paid in USDC, the same money moving through the system, not a second token to keep topped up. Settlement under a second, so a balance check every few minutes doesn't cost more than the payments it's protecting.
That's the whole bet: money that moves as fast as the decision to move it.
The money already moved on-chain. The agent didn't.
USDC already sits in real company treasuries as real settlement money. What's been missing isn't the rail, it's an agent trustworthy enough to be handed the keys and left alone.
Arc is the first L1 built specifically so that agent doesn't need a human chaperone: USDC-native gas, sub-second finality, and a Circle stack built for custody without a human touching a key.
What's real, what's gated.
- realLive on Arc mainnet: Circle Live-environment wallets, MandateEscrow, x402 nanopayments, autonomous cron, webhook-confirmed settlement end to end
- gatedStableFX: RFQ-only access, no self-serve signup yet. Non-USDC obligations are correctly flagged, not yet auto-settled. CCTP liquidity top-up currently disabled on mainnet pending a funded source chain.
A primitive, not another single-purpose demo.
Relevance to Arc
Impossible on a chain with volatile gas or probabilistic finality: USDC-native gas and sub-second settlement are what make per-obligation mandates economical at all.
Technical credibility
Real contracts, real mainnet deployment, a real autonomous caller · not a testnet-only illustration.
Depth
Solves trust and accountability, atomic multi-party settlement, and portable reputation in one primitive, rather than one narrow feature.
Promise
Open by design: any other agent or hackathon builder can fund, fulfill, or read a mandate today, no permission needed.
Where this goes from here.
What we're looking for.
The microgrant
Non-dilutive fuel to keep building the primitive out, not just the agent on top of it.
StableFX access
The one piece that's flagged, not faked. This closes the last gap between "correctly identifies" and "fully autonomous."
Introductions
To a real treasury with genuine recurring obligations to pilot against, and to other Arc builders whose agents could be MandateEscrow's second caller.
