Arc Eye currently functions similarly to a DEX filter; DEX functionality will be added to the Arc testnet later.
Updated with new features...
Coming soon!

Hurry up and wait. A financial system tale as old as time.

On Arc, payments, FX, and treasury workflows are built to move in real time.

Move fast. Move agentically. Move forward.

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.

At @AIAgentsSummit Berlin, developers explored what happens when AI agents can do more than generate outputs.

Using Circle Agent Stack, builders showed agents that could hold wallets, manage budgets, discover paid services, pay for APIs or data, coordinate workflows, and return receipts.

Agents are starting to look like economic participants.

They need:
→ Wallets
→ Budgets
→ Low-cost payments
→ Programmable settlement
→ Receipts
→ Infrastructure for repeatable machine-to-machine activity

That is the kind of future Arc is being built to support.

Money's second act runs on @Arc. @0xrachelita lays out why in this article.

The first act got dollars onchain. The next one is about money that works: stable fees, final settlement, opt-in privacy, and agents settling at machine speed.

Arc 🤝 Chainlink

@arc has joined the @Chainlink Scale program to provide developers with secure access to premium enterprise-grade infrastructure.

Builders on Arc can now leverage Chainlink’s enterprise-grade suite of services to power advanced onchain applications, including:

→ CCIP
→ Data Streams
→ Data Feeds
→ Proof of Reserve

Arc is built for composable applications from day one.

Thanks for the shout out @TimHaldorsson!!

The complete Arc House and community vision is at 30% completion so far. Expect a whole lot more to come

We’re just getting started

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: https://t.co/ku35ztsvqS

Sidekick: Perpetual futures built for AI agents, not humans. Per-block funding, no liquidations, on Arc.
Submission Showcase: https://t.co/GLrxOYbOyN

🏆 Best Smart Contracts on Arc with Advanced Stablecoin Logic

Thanks to all the teams that took part and congratulations to the winners!

The Arc builder ecosystem keeps growing.

@bobbilee @arc Fantastic! Every day is a perfect score!

Vyper on Arc Testnet shows what comes after agentic payments.

Agents need more than wallets. They need identity, settlement, and programmable controls.

@vyperlang is building toward agentic economic workflows with:

→ ERC-8004 agent identity
→ x402 payment flows
→ USDC settlement
→ Escrow, subscriptions, splits, and spending limits

A blueprint for agents that transact under rules, not just send funds.

[Arc @arc]

Arc Transaction Memos are now available on Arc Testnet.

Memo-enabled calls add structured context to contract execution, preserve sender attribution, and only emit memo events when the contract call succeeds.

Use them to:
→ Add invoice IDs, payout refs, or customer IDs
→ Track payment context onchain
→ Make payments easier to reconcile

In this bootcamp you'll learn all about stablecoins and @arc , the stablecoin-native Layer-1 blockchain.

Arc is built for agents that do real economic work.

At the @AIAgentsSummit Hackathon in Berlin, builders can use Circle Agent Stack and Wallet, to create agents that can:
→ Hold a wallet
→ Manage a budget
→ Discover paid services
→ Pay in USDC
→ Return receipts and transaction logs
→ Coordinate across tools, APIs, or other agents

The best projects will go beyond “an agent sends USDC once” and show repeatable workflows where the wallet is part of the agent’s job.

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.

New in the Unified Balance Kit technical series: Production Safeguards and Recovery Patterns for spend()

Before calling spend(), applications need safeguards for fee validation, delegate readiness, and recovery if a mint fails.
