One signal is getting harder to ignore.
As of July 2026, @USDC accounted for 99.3% of x402 settlement volume for agent payments.
Now look at what @circle is building around it.
Circle Agent Stack gives agents a wallet, programmable spending controls, service discovery, and the ability to pay through x402 without relying on payment flows designed for humans.
At the same time, @arc is being built with USDC as native gas, predictable dollar-denominated fees, and sub-second deterministic finality.
So when I watch a tutorial like this, what stands out isn’t only how easy agent payments are becoming.
The bigger signal is that the infrastructure for the agentic economy is starting to come together.
If you’re building or integrating for that economy, Arc is getting harder to ignore.

This hits close to home. Since joining Arc and seeing the Architects actively preparing their projects, the builder vibes here are real.
The environment genuinely pushes you to turn ideas into reality. Ideas used to just swirl in my head and disappear. Now I'm learning to piece together, refine, and organize the puzzle.
Even though my project isn't finished yet. Still in the stage of maturing the technical architecture design. I genuinely feel like I've leveled up.
The exploration process is exciting and challenging at the same time.

Jeremy Allaire just shared his treatise on The Agentic Economy. It lines up perfectly with what Arc is enabling.
As AI agents start taking on real firm work and value moves natively on programmable networks, rails that are truly stable, fast, and programmable become essential. Not legacy systems full of uncertainty.
Arc is built for this moment. With USDC as native gas, deterministic sub-second finality, and safe programmable capabilities, Arc provides the foundation where agents can hire, complete tasks, escrow value, and settle payments autonomously.
Agents are no longer just service consumers. They can now get work and generate value on their own.
Projects like @arclens_app show this direction clearly.
For developers and builders, this is the opportunity to create systems where agents function as true independent economic participants.
Build on @arc
November was an amazing month to be on Abstract, with a ton of new Portal updates and exciting ecosystem launches.
Here's THE recap in case you missed it 🧵
It should not be understated how impressive it is that Ethereum has had 17 major upgrades and not a single instance of downtime.
Remember that this is a fully decentralized network without thousands of nodes across the world.
Just fantastic work overall by the core ETH devs.
Tomorrow: Fusaka
Ethereum’s second major upgrade this year.
→ Feature highlight: PeerDAS - Unlocking up to 8x data throughput. For rollups, this means cheaper blob fees and more space to grow.
