[WalletConnect @WalletConnect]

MILESTONE: a whopping $155.9 billion in @USDC by @circle moved through the WalletConnect Network in the first 6 months of 2026 alone.

This clearly demonstrates that USDC has become the connective tissue of the onchain economy, and WalletConnect its movement vehicle.

This is a great tool for booking restaurant reservations in LA since every new spot is always impossible to get a table.

@Jun__Yoo Stablecoin backed Visa cards with USDC is a killer combo because devs can bundle debit and credit cards into one. Metamask was the first to bring this to market.

@0xDezman @USDC It’s coming soon. Looping @chrisries from our privacy team here.

[Corey Cooper @corey__cooper]

Developers, end-users, and businesses will receive a huge upgrade in the @USDC transaction experience on 9/16/26.

- Every transaction fee is stable and predictable
- End-users don't have to source a volatile native token to send money
- Arc meets the bank's compliance and risk requirements

[Arc @arc]

Welcome to Arc 101.

Episode 1 breaks down the fundamentals of Arc, from stablecoin-native infrastructure and core network primitives to the developer building blocks available through Circle.

If you’re getting ready to build on Arc, this is where to start.

I tested this out with @zerodev_app last night and this is a huge unlock for building programmable chain abstracted base:0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 experiences

[Circle Developer @BuildOnCircle]

Gateway now supports ERC-1271 for transfer authorization.

That means smart contracts and smart wallets can authorize Gateway transfers through signature validation, without relying on an EOA delegate.

In this Release Notes episode, learn about:
→ Setting contractSigner: true on a Gateway transfer request
→ How Gateway validates burn-intent signatures through ERC-1271
→ Limits of read-only validation

[Corey Cooper @corey__cooper]

You definitely get it

[CriptoPoeta 🚬🥃 @criptopoeta]

Esto… lo cambia todo TODO. Esto es lo que rompe el gran problema de permitir que la buena UX/UI y web3 sean por fin compatibles al siguiente nivel.

🧘🏻🦖⚡️👊 well done

Ahora solo falta @arc en mainnet

[Corey Cooper @corey__cooper]

Seller pages are live on https://t.co/JP75T7VLFJ! Now you can see detail information on all the companies that are selling to agents earning @USDC.

[Danny Organ @organ_danny]

.@USDC is the highest velocity money, and it's not even close!

This will only further increase as the agentic economy takes off (99% of agentic txns already happen in USDC).

h/t @artemis

[Corey Cooper @corey__cooper]

Agentic economy is just getting started but many of the companies listed here are going to help make this a massive market for the internet. https://t.co/G5T0yIr6kh

Circle is here at the @BerkeleyRDI for the Agentic Summit 2026.

If you’re here, stop by our expo booth to see how Circle Agent Stack can expand what your agents are capable of doing when given @USDC…the currency of the internet.

@ryan_morr Cloud agents are unlocking so much flexibility in development cycles

[Corey Cooper @corey__cooper]

I'm looking forward to this project. Inference billing infrastructure for humans, agents, and model providers.

[jamie @Jamie_Alethieum]

MPP-I: Machine Payments Protocol for Inference

Read the paper on @huggingface: https://t.co/l8hHJSH9sS

MPP-I is a @mpp compatible, payment profile for inference. It defines the inference specific payment lifecycle inside an MPP compatible challenge, credential, receipt.

[Corey Cooper @corey__cooper]

The headless internet for agents is here and @circle is here to support your needs on the buy and sell side.

[Circle Developer @BuildOnCircle]

A new customer is forming for API providers: autonomous agents.

With x402 and Circle Agent Stack, agents can discover your API, pay per request in USDC, and use your service without a checkout page, account setup, or subscription.

Turn your endpoint into an agent-ready service: https://t.co/isWWFPXEoG

[Seal @heysealai]

54% of consumers say an agent acting on their behalf would be genuinely helpful.

Only 1 in 12 has ever used one.

Seal is built to close the gap between wanting an agent and actually being able to use one.

[Corey Cooper @corey__cooper]

@kleffew94 It’s the worse!

[Corey Cooper @corey__cooper]

@echulshin @heysealai 🔥

[Corey Cooper @corey__cooper]

@ryan_morr Dope!

[Corey Cooper @corey__cooper]

The future of software engineers will probably be them managing a fleet of agents from their iPhone. The real ones deploying cloud agents to manage codebases know what I’m talking about.
