Welcome to Arc 101, Episode 4.
Follow a single USDC transaction across Arc, from send to final settlement.
This episode traces each layer the transaction touches, each validation it passes, and how Arc processes stablecoin movement through the network.
See the transaction lifecycle on Arc.
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.
Hibachi is building FX spot and perpetuals on Arc.
@hibachi_xyz pairs a high-performance offchain central limit order book with zero-knowledge verified settlement on Arc, giving professional FX participants a path to low-latency execution with onchain verification.
Why Arc:
→ Deterministic sub-second finality
→ USDC-denominated gas
→ Opt-in privacy
→ CCTP-enabled collateral movement
Arc is built for institutional-grade financial applications.

When you spend from a unified USDC balance without explicit allocations, Unified Balance Kit runs a greedy allocator across your confirmed per-chain balances to pick your source chains for you.
Our new blog post walks through the auto-allocation path end to end: balance discovery, greedy chain ordering, fee reserves, and burn-intent construction.

Arc builders showed up in London.
We kicked off the Arc at Encode Hub meetup series with developers exploring programmable money, stablecoin rails, and the agentic economy.
The Arc x Encode virtual Programmable Money Bootcamp is up next.
Builders will get:
→ Technical workshops
→ Mentorship from Arc and Encode
→ Hands-on hackathon support
→ Time to build real-world apps on Arc

Most capital market settlement still takes days.
This ties up working capital while adding operational risk.
Arc is designed to support real-time settlement for tokenized securities, prediction markets, collateral management systems, and more with atomic DvP and deterministic finality.

Circle Agent Stack helps developers build agents that can do more than generate text.
In this guide, an agent uses Circle Agent Wallet to:
→ Find a paid voice-call service
→ Pay for the resources it needs in USDC
→ Place the call
→ Return a transcript, recording URL, and spend details
→ Run the workflow on a recurring schedule
Agents are moving from planning work to completing work.

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!

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.
The reputation system on NaraChain is subtle but powerful. Agents with higher rep get better tasks and earn more. Meritocracy for machines. #NaraChain@NaraBuildAI
