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.
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.
Privacy should be intentional, visible, and controlled.
Arc’s privacy roadmap is designed around future opt-in confidentiality, giving teams a way to choose where privacy belongs in a workflow.
For builders, that could open the door to product experiences with:
→ Privacy status indicators
→ Fee visibility
→ Clear user controls
→ Governed access for authorized parties
→ Confidential workflows without black-box opacity
Privacy without anonymity, designed for real financial apps.
Arc Testnet is upgrading to v0.7.2.
This release activates on Testnet on June 18, 2026 at 5:00 AM PT, bringing new features to the network.
Please upgrade your testnet nodes before activation to avoid desyncing.

The Bored Room was an eight-hour waiting game about legacy financial rails.
Approvals stalled. FX leaked value. Banking hours got in the way. The payment never arrived.
Funny because it was fictional.
Painful because it was familiar.
Arc is designed to fix this. An open internet platform built for:
→ 24/7 settlement
→ Sub-second finality
→ Stablecoin-native payments
→ Programmable FX
→ Agentic economic activity

We’re in New York for ETHGlobal New York from June 12–14, 2026 with $15,000 in prizes for best submissions.
Building on Arc in NYC? We’re looking for stablecoin-native applications built on Arc and with Circle tooling across wallets, interops, App Kit, and the new Agent Stack.
Come ship with the team, get hands-on support, share product feedback, and compete for prizes.
See you here!

Arc’s privacy roadmap is designed for real financial workflows where confidentiality matters:
→ Payroll-style payouts
→ Treasury operations
→ B2B settlement
→ FX workflows
→ Tokenized asset activity
The goal is privacy with governed visibility: sensitive activity protected from public exposure, while authorized parties retain defined access.
A future path for confidentiality with control in stablecoin 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.
Arc Public Testnet is now live.
Open to developers and enterprises globally, Arc is the Economic OS for the internet that unites programmable money and onchain innovation with real-world economic activity.

Zero gas fees mean even micro-agents can survive. My tiny task-solver earns fractions of NARA, but with no fees, every fraction counts. #NaraChain@NaraBuildAI
