ArcQRPay — Exploring Cross-Chain Payments on @arc Through a QR-Based Payment Experience.
Over the past few weeks, I started building a small Web3 payment project on @arc called ArcQRPay.

Technical Office Hours is on September 3 at 8 AM ET.

@hj_chen is hosting this one on account abstraction on Arc: how it works when gas is already USDC, where wallet providers stand on Arc support, how to sponsor gas for users, and a live demo.

Come with questions.

@onnet1001 great. congrats... bonus

[leonix0x @Leonix0x]

Another exciting step for @Arc.
🚀 As someone still learning, I love seeing the network continue to evolve and improve its infrastructure. The more stable and reliable Arc becomes, the more opportunities builders have to create real-world applications.

🚨 Arc Testnet upgrade is coming!
September 3 — the network will undergo a hard fork as part of the Zero8 upgrade.
Builders, make sure you’re ready and keep an eye on the latest updates.
Tell your friends. Zero8 is coming. ⚡️

Arc Testnet is upgrading to v0.8.0.

This release activates on Testnet on Sep 3, 2026 at 3:00pm UTC. Zero8 improves protocol correctness and strengthens the Arc Public Testnet for further building and testing.

Please upgrade your testnet nodes before activation to avoid desyncing.

Onchain credit is expanding.

@Morpho is building capital-efficient lending markets on Arc.

Coming soon.

[Arc @arc]

Arc was built for developers exploring what’s possible when stablecoins, wallets, and programmable payments come together.

@OpenVPP is using Arc Testnet to explore real-time energy settlement across EVs, utilities, and grid-connected devices, including:
→ Stablecoin settlement
→ Gas-sponsored wallets
→ Machine-to-machine payments
→ Nanopayments for grid data access

As a proof of concept, OpenVPP has built a grid-balancing agent that pays $0.0001 in USDC every 4 seconds to access grid frequency and pricing data, evaluate a battery dispatch decision, and track the resulting data cost.

A technical look at what they’ve built on Arc: https://t.co/KmCTDkHwZ9

Uniswap on Arc opens up core DeFi building blocks that depend on real onchain liquidity.

Builders will be able to design:
→ Lending and borrowing flows
→ Token launch and liquidity bootstrapping
→ LP strategies built around USDC-native gas
→ Structured products and derivatives that depend on tighter execution

[Circle @circle]

Arc Mainnet launches September 16.

Where Arc stands today:
→ More than half a billion testnet transactions
→ Nearly 3 million wallets
→ 100+ partners active on private mainnet
→ Initial validator cohort expected to help operate the network alongside Circle

Arc is being built as financial infrastructure for the world’s financial markets.

[Arc @arc]

Institutional banking meets internet-speed settlement.

@StanChart is bringing 24/7 real-time payments to Arc.

Coming soon.

[Arc @arc]

TLAY on Arc shows what machine-to-machine payments can look like in practice.

Builders can now explore patterns where devices:
→ Hold wallets
→ Read price signals
→ Make autonomous payment decisions
→ Settle USDC transactions continuously
→ Operate without custodial intermediaries

Arc’s sub-second deterministic finality, USDC-denominated gas, and stablecoin-native infrastructure make these high-frequency payment loops possible.

[Arc @arc]

Welcome to Arc 101, Episode 3.

Traditional cross-border payments move across multiple intermediaries, ledgers, and systems.

Arc takes a different approach with stablecoin-native infrastructure built around a shared open ledger.

Liquidity infrastructure is live on Arc.

@Uniswap will deploy on the upcoming Arc Mainnet, bringing the most widely used onchain AMM protocol to Arc’s stablecoin-native settlement layer.

Builders have been asking about liquidity since testnet launched. This is a key unlock for building a broader range of DeFi applications on Arc.

[Arc @arc]

Liquidity found its home.

@Uniswap is bringing deep pools to Arc.

Ready to dive in.

[Arc @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.

Arc Mainnet launches September 16.

Arc is an open blockchain network being built for the world’s financial markets, real-time money movement, and agentic economic activity.

Arc’s founding validator cohort includes @BlackRock, @The_DTCC, @galaxyhq, @GlobalPayInc, @Mastercard, @MoneyGram, @ICE_Markets, SBI, @StanChart, Sumitomo Corporation, and @Visa.

This is a different model for onchain infrastructure: a network secured by the institutions building on it.

Arc is already gaining traction across major institutions.

@BlackRock, @BNYglobal, @The_DTCC, and @StanChart are each exploring integrations spanning tokenized asset settlement, custody, stablecoin access, FX, and repo infrastructure.

Arc is also expected to launch with a broad ecosystem across liquidity, payments, access, and infrastructure with more to come.

Liquidity / DeFi: @aave, @AerodromeFi, @FalconXGlobal, @galaxyhq, @GSR_io, @keyrock, @Morpho, @nonco_otc, @Uniswap, @OfficialXFX

Payments: @raincards, @ThunesPayments, @wirexapp

Major Exchanges and Wallet Providers: @BinanceWallet, @chainlink, @FireblocksHQ, @krakenfx, @Ledger, @MetaMask, @Official_Upbit, @Uniswap

Participants building on Arc experience an open platform powering the world's financial markets, real-time money movement, and agentic economic activity.

Whether you're launching a financial application, integrating stablecoin flows, or experimenting with new, AI-powered economic models, Arc gives you the tools to build what isn’t possible anywhere else.

Arc Mainnet launches September 16.
