Next up on the roadmap: The AI Agent Bridge
We're building a dedicated arc-nano-kit/ai plugin that allows LLMs and autonomous agents to natively understand HTTP 402 errors and pay for API consumption on the fly using their own USDC wallets.

It’s one thing to write about usage-based billing on Circle Arc. It’s another to let anyone test it right in their browser.
The arc-nano-kit Live Demo is officially deployed.
Hit the paywalled endpoint, experience the automatic x402 payment flow, and see how fast USDC nanopayments actually are. No terminal required.

Payment verification isn't something you ship without tests. 🛡️
Just added 26 unit tests to arc-nano-kit, covering the core x402 payment engine, billing calculator, and usage metering.
If you're building Agentic Commerce and handling USDC, correctness isn't optional.

Next update is already scoped:
ethers adapter + scanner profiles.
The goal: strict CI checks for production transaction paths, lighter local checks while teams integrate Base Builder Codes.
SDK attribution should feel boring, automatic, and hard to forget.
Base Attribution OS update 1.
`bao scan-repo` now catches more unattributed tx flows before they hit mainnet:
- viem
- wagmi hooks
- wallet sendCalls
- agent transaction tools
Builder Codes should be enforced like tests.

Shipped the first version of Base Attribution OS.
The idea is simple:
if @base rewards, analytics and visibility depend on attribution, Builder Codes need to be enforced like tests. @CoinbaseDev
Today: SDK + CLI + GitHub Action.
Next commit: smarter CI scanner for unattributed tx flows.

Our new @CoinbaseDev portal is looking awesome! It's the best place to build in crypto.
It gives access to all our powerful developer tools (wallets, payment APIs, x402, etc) in one dashboard. You can even launch a branded stablecoin, backed 100% by USDC.

AI agents need infrastructure that can match the speed and determinism of software.
Arc gives developers a more usable foundation for the agentic economy with:
→ Gas paid in stablecoin (starting with USDC)
→ Sub-second deterministic finality
→ Programmable settlement logic
→ Opt-in transaction privacy
That makes it easier to build systems where agents can transact, coordinate, and settle value in real time.

Circle just shipped incredible primitives for the @Arc ecosystem: Nanopayments, the x402 protocol, and Gateway batched settlement.
But how do you actually use them in production?
Introducing ⚡️arc-nano-kit ⚡️
The open-source middleware that turns @Circle Nanopayments into drop-in usage-based billing for APIs and AI agents.

Prediction markets become more powerful when they start functioning like real market infrastructure.
That requires predictable costs, credible settlement, multi-currency flexibility, and architecture that can support higher-trust financial and operational use cases.
Arc is built to support that evolution.
