Arc builders in Bueno Aires.

Arc 🤝 @wirexapp Wirex BaaS is expanding to Arc, bringing stablecoin banking and payment infrastructure natively onchain. Wirex One is also expected to launch on Wirex’s infrastructure on Arc. This brings: → USDC and EURC card settlement on Arc → Wirex BaaS infrastructure backed by principal memberships with leading card networks → Recurring payments activity moving onto Arc → A stablecoin neobank experience built on Arc-native infrastructure Arc is built for real payments volume, not just idle liquidity. More to come.

Mystery fees, intermediary currencies, and value lost before settlement. Arc fixes that with predictable fees, transparent pricing, and instant FX settlement.

On Arc, asset servicing becomes programmable. → Conduct transfer and whitelist checks at the token level → Automate redemptions and distributions → Execute corporate actions with onchain logic Rules can be embedded in the asset and enforced across counterparties.

Most chains will address quantum security when they have to. Arc is being designed with future quantum capabilities in mind from the start. @gordonliao explains how Arc incorporates quantum-resistant signatures and a mapped path for migrating assets to quantum-safe wallets.

Arc 🤝 Pyth @PythNetwork is delivering high-frequency, proprietary financial data for developers building on Arc Testnet. This gives builders the precision and reliability needed to power real-time applications across DeFi, trading, and next-gen financial infrastructure. → Low-latency price feeds from market participants → High-fidelity data for advanced financial use cases → Infrastructure designed to accelerate new asset listings' Arc is built for performance. Designed for financial applications that cannot afford delay.

The Arc team joined builders in New York for ETHGlobal NYC, with 15,000 USDC in prizes for teams building on Arc. Across six tracks, 65 teams shipped apps and primitives exploring: → Advanced stablecoin logic → Chain-abstracted USDC flows → Prediction markets → Agentic economy use cases → Arc integrations for existing projects The creativity, ambition, and quality of the submissions stood out. Here’s what the winning teams built: 🏆 Best Agentic Economy with Circle Agent Stack Mars: On-chain audited marketplace where AI agents safely buy verified skills. Submission Showcase: ethglobal.com/showcase/mars-… Sidekick: Perpetual futures built for AI agents, not humans. Per-block funding, no liquidations, on Arc.

Submission Showcase: ethglobal.com/showcase/bitro… Thanks to all the teams that took part and congratulations to the winners! The Arc builder ecosystem keeps growing.

Builders need privacy primitives they can apply to real products. Arc’s future confidential execution pathways are designed to support opt-in private transactions and private smart contract states in a familiar EVM environment. That could help developers build for: → Private lending flows → Perps and trading workflows → Protected positions and strategy → Multi-step private app logic → Public and private transactions in the same block A roadmap for composable privacy in onchain finance.

Onchain liquidity is coming to Arc. @Uniswap is coming to Arc, to bring deep liquidity and a leading swap infrastructure to Arc’s stablecoin-native ecosystem. This would give builders: → Proven onchain swap infrastructure with $4.4T in volume → Deep stablecoin liquidity for trading and token discovery → A familiar venue for users to access assets on Arc More to come.

XyloNet is building stablecoin DeFi and social tipping on Arc Testnet. Built by ForgeLabs, @Xylonet_ brings together: → Stablecoin swaps for USDC and EURC → Liquidity pools → CCTP V2 bridging → ERC-4626 vaults Alongside XyloNet, PayX adds a consumer payment flow that lets users send USDC tips (which are held in smart-contract escrow) to an X handle before the recipient has connected a wallet. Together, they show how Arc can support both DeFi infrastructure and payment UX on the same stablecoin-native settlement layer. arc.io/blog/how-xylonet-is-b…

Onchain lending and borrowing on Arc.

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.

Arc Moves Fast. This Does Not. Watch what Arc was built to leave behind. June 9. arc.io/theboredroom

Quantum computing introduces long-term risk for digital infrastructure, from wallet signatures to validator integrity and more. Circle’s post-quantum whitepaper explores Arc’s phased approach to resilience across: → USDC → Smart contracts → Validators → Infrastructure systems Planning for long-term security and institutional adoption. arc.io/post-quantum-whitepap…

Corporate treasury has two modes right now: idle in accounts or in transit for days. Arc unlocks a third: deployed, earning, visible in real time.
