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.
Another record month for adjusted stablecoin transaction volume.
USDC continues to play a major role in powering always-on money movement across the onchain economy.
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.
I wrote about why money's second act runs on @Arc.
The first act of digital money brought dollars onchain. The next one needs infrastructure built for businesses, institutions, and agents: stable fees, final settlement, opt-in privacy, and payments at machine speed. https://t.co/i4B0Rl13Fw
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.
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.

Lending infrastructure is building on Arc.
@Aave V4 is exploring coming to Arc, to bring cutting edge liquidity protocol infrastructure to Arc’s stablecoin-native ecosystem.
This would give builders:
→ Familiar onchain liquidity protocol infrastructure
→ Stablecoin-native lending and borrowing flows
→ Featuring Arc’s native asset set at launch, including USDC, EURC, and cirBTC
More to come.
