More assets. Familiar tools. One integrated stack.
CCTP and Bridge Kit, now support expanded multi-asset workflows, with Arc as a Day 1 destination for USDC, EURC, and cirBTC on supported routes.
Interop on Arc is here.
A new integrated stack for builders creating crosschain applications on Arc.
Build with:
→ Move supported Circle-issued assets natively with CCTP
→ Bring third-party tokens crosschain through wrapping
→ Launch new multichain assets with CTS
→ Manage unified crosschain balances with Gateway
Crosschain liquidity, without the complexity.

There is one Arc Studio feature that, if you’re not using while building onchain, you’re debugging blind.
It’s called Tracing.
Let’s imagine you’re building an app that sends USDC. You click send and approve the transaction in your wallet, but your app is still loading.
Now you’re not sure what’s going on.
Did the wallet connect? Was the transaction submitted? Was it confirmed onchain? Did the contract emit the expected event?
Instead of checking your browser console, wallet, and explorer separately, Tracing shows the full flow in one timeline.
You can see every step, how long it took, where something failed, and the data your app sent and received.
You could paste logs into an AI coding tool and ask it to debug them. But the real value of Tracing is that it automatically captures the full onchain flow first, so the AI has the right context to explain what happened.
You can also click Ask Studio and let the AI explain the trace for you.

CCTP is expanding beyond USDC.
Developers can now enable crosschain transfers for supported Circle-issued assets, like EURC and cirBTC, and third-party assets using CCTP’s messaging infrastructure.
In this video, learn:
→ How CCTP supports more assets across blockchains
→ What this unlocks for developers
→ How to get started sending EURC over CCTP
CCTP V2 on @SuiNetwork is now live.
Developers now have access to native USDC burn and mint transfers, inbound Fast Transfer, hooks, programmable messaging, and Sui specific tooling.

USDC Bridge now supports @Solana.
Move USDC directly between Solana and 18 supported ecosystems through a simple, predictable bridging experience built by Circle.
Access Solana liquidity, apps, and market opportunities without fragmented flows or unnecessary complexity.

Give your agent a budget, not tools to wire up.
With SELAT, your agent finds the paid APIs and skills each task needs and pays for them as it goes, from one USDC balance funded on @arc.
Your turn: build a cross-rail workflow with SELAT and show us what your agent did.

Want to give your agent access to USDC (the $ agents use for 99% of txns)?

An agent can research market sentiment, pay for the services it needs, create a brief, and deliver the update by phone.
That is the shift Circle Agent Stack is built to support: agents that complete workflows, not just generate text.

This user experience of moving money from one wallet to another wallet will only continue to improve. Frictionless money movement is already here.
Programmable money on @arc is NEXT LEVEL.
I just sent USDC from my Arc wallet to my CashApp Polygon deposit address which immediately settles as dollars in a bank account.

Creating the wallet is the easy part. The part that actually kills conversion: getting money out of the bank an onchain (without getting mogged by fees), paying gas, and finishing one real transaction.
@GetOnramper says up to half of fiat-to-crypto swaps still fail after KYC. That’s a lot of people who already said yes and then bounced.
1Shot teamed up with @circle to fix this.

x402 is becoming a building block for agentic commerce.
@organ_danny co-authored the x402 whitepaper and is working on products to grow the agentic economy at @circle.
He'll be joining us at Agentic Zero. We can't wait to hear more!
