This is right which is why we built Arc Studio, a coding agent harness for onchain development with access to all the best SDKs, skills, and protocols for integrating programmable finance. Try it:

I don't think people really understand how important sub-cent gas free payments will be for the internet. @arc + @circle + @USDC provides this today. Quicknode is the prime example of a data provider that will help unlock machine to machine payment use cases that fiat rails can't support.

Thanks to @ZeroDev, you can go from USD in @CashApp → USDC on @arc without ever manually buying USDC. Smart routing addresses on Polygon or Arbitrum handle the path to Arc behind the scenes. This is what a smooth stablecoin onramp should feel like.

Being able to drop Arc Studio CLI in your Cursor agent harness and have it deploy and test smart contracts on Arc Testnet with cloud agents is a magical DevEx because building onchain can be very difficult.

If you are building in the fintech space and need to integrate stablecoin infrastructure but don't know anything about smart contract development, I highly suggest you try out Arc Studio. Goto copy the CLI prompt in your favorite coding agent harness, and let it cook up the programmable financial flows you've always wanted to build but didn't know how to do because you didn't know Solidity.

We've spent a lot of time calibrating how SELAT matches an agent's intent to the right paid endpoint. Adding Jev as an independent judge has meaningfully raised our confidence in that step. An agent asks for "smart money 13F positioning for a stock." SELAT's ranker works on matching words, so it finds every endpoint whose listing mentions smart money, including a prediction-market feed that can't do the job. Pay it and the payment still clears; you just bought the wrong thing. Our catalog is open, which makes this harder. SELAT searches many registries at once, and anyone can list. ELI5: ask for a plumber and the ranker hands you a pile of business cards that all mention pipes. One fixes pipes, one sells pipes, one is a plumbing magazine. SELAT now checks the pile before your agent pays. Jev, @typesafeai's System One model, looks at each card and gives the odds that it can actually do what the agent asked. Jev doesn't get the final word. A gate decides: swap if Jev(top candidate) ≥ 0.6 and Jev(SELAT's pick) ≤ 0.4 Otherwise the pick stays. When SELAT's ranker already got it right, nothing changes. For the 13F request, SELAT's ranker put the prediction-market feed first. Jev(SELAT's pick) = 0.04, and Jev(top candidate) = 0.92 for an SEC filings endpoint that returns fund holdings. Both conditions held, so the pick flipped and the agent picks the endpoint that can do the job. Finding the right endpoint only matters if the agent can pay it. The right answers often sit on different rails. SELAT built that layer first. One balance, funded once, pays x402 and MPP across protocols, schemes and chains. SELAT can rank the whole open catalog and the agent can buy from whichever merchant it picks. Every SELAT search now gets a second opinion from Jev. Agents can let it flip the pick today. See it work across 253 real requests:

Used Arc Studio to write and deploy a Spigot on @arc which enables escrowing a borrower's revenue streams and automatically directing those cash flows toward loan repayment. This is an onchain finance innovation that @creditcoop_xyz brought to market to power pretty much all stablecoin back card settlement. Try it:

So we stopped sending people somewhere else to fund the thing. 1Shot Wallet now has Onramp Kit and @arc built in. Card or bank → USDC, in the same flow. No exchange tab. No “come back when you have crypto.”
