50 days ago, @ArcHub_ was just an idea. Today, it’s live on Arc Testnet 💥 I started building ArcHub on July 17 with a simple goal: create a better way to experience Arc, batter UI, faster, easy. Today, we’re shipping the first version, built around payments, swaps, exploration, AI & onchain reputation But this is just the beginning. The future is much bigger and we’re going to keep building, improving & pushing ArcHub forward as the Arc ecosystem grows. The new journey starts now 🩷🩷 Try ArcHub: archubapp.xyz/ Read the full vision here 👇

The Total Value Locked in DeFi on @arc increases every day.

LT;DR for what is Interop : This is @circle full interop stack built into arc so it can work as a liquidity hub, not another isolated L1 Users move assets with fewer steps. Builders stop stitching bridges, wallets, and balance systems together 𝗪𝗵𝗮𝘁 𝗶𝘁 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗶𝘀: • CCTP : native burn-and-mint for Circle assets like USDC, EURC, and cirBTC. Fast Transfer on arc routes is under 10 seconds • Wrapping : path for third-party tokens to move across chains without Circle taking control of the asset. • CTS : standard for launching a new multichain token from day one, with allowlists, rate limits, pause & upgrades already in the design. • Gateway : one unified balance across supported chains instead of a separate bag on every network. USDC is live on arc + eth ≠ EURC and cirBTC are next • Forwarding Service : destination tx gets relayed so the user doesn’t need gas on the other chain. 𝗪𝗵𝗼 𝘁𝗵𝗶𝘀 𝗶𝘀 𝗳𝗼𝗿: • Wallets and exchanges that want native USDC/EURC movement instead of another bridge integration. • Apps that need users to deposit on one chain and use funds on another without a broken UX. • Treasuries that want liquidity sitting on arc, then available where the trade + payout + DeFi position actually is. • Token issuers who want one asset, one policy layer and distribution across chains without rewriting the contract every time.

just crossed 1.5k friends 🥹🩷 started creating almost 1 year ago one year of posting, failing many times, learning everyday, building valuable thank you to everyone who followed before it looked “worth it” it’s proof that consistency still compounds, but yaah not fully consistent that a other think 😁 Love you all 🩷🩷

Really cooked easy 10× with Tranches

gArc 🩷 Day 15th to as Architect on @arc Congratulations again to every Architect who got selected. I’ve been here since the early days. Everyday working, writing, helping people move through arc the right way First week is done on Mainnet with strong growth & community Also I'm building @archub_ on mainnet too & goes live this week. Still building hard Still contributing Still shipping on arc Consistency is still the only signal that matters. BULLISH 🩷

Architects, before asking that question again… 👀 There’s a good chance the answer is already in the @arc house FAQ A lot of the questions being asked repeatedly are already covered there including: • Account access • Architect Program • Restricted pages • Points and posts • Projects • Other common Arc House questions Big appreciation to @silencexlm for putting this together and addressing many of the common questions and concerns from the community Save the FAQ Check it first You might find your answer faster than you think.

something interesting if you’re actually building on @arc this week Arc Studio is live, a easy way to build ; This is not a chatbot with a chain sticker on it, it’s @circle coding agent that turns a sentence into a full-stack onchain app, like UI, backend, Solidity & with USDC wire -- What it is: > you describe the product > studio writes the contracts > previews the app live > can deploy to arc testnet (With 8 other EVM testnets to test) > you can also paste a live contract address and it reads the chain > then builds the frontend around what’s already deployed -- Two ways to in: ▪︎ visit : studio.arc.io ▪︎ CLI / Cursor / Claude / Codex as a subagent (`@circle-fin/arc-studio-cli`) -- What it actually understands: ▪︎ CCTP > direct Gateway > Circle Wallets > Contracts .... ▪︎ so the output is closer to payments, escrow, checkout, bridges, agents (not just a random page) -- Useful details: ▪︎ default network is ARC ▪︎ built-in testnet faucet ▪︎ export the code to your own repo ▪︎ it does not deploy to mainnet for you ▪︎ it can resolve ERC-8004 agents and tell you if one is payable via x402 ▪︎ templates exist: USDC checkout, crosschain bridge, prediction market, onchain profile -- How i’d use it today as builder: 1. pick one small product (checkout or escrow is enough) 2. generate on testnet 3. open the contract panel and read every function 4. send a real test tx from the preview 5. pull the code locally and treat it like your own that last step is the whole job studio is a starting surface the build is still yours Go: studio.arc.io Learn more: docs.arc.io/ai/arc-studio if you’re on @arc to ship, this is the tool that shortens the distance between idea and something you can test Super bullish 🩷🩷 @samconnerone @bobbilee @0xemmyeth

gm gm We are back haha $SUI on the track 👀👀

First week as a builder on @arc mainnet The chain opened with institutions producing blocks and USDC paying gas, live to positioning We spent months to shipping @ArcHub_ on testnet but finally next week going live on mainnet too Pay. Swap. Bridge. Transfer. Gifts. Payment links. Mainnet landing... If you are building, use official rails and ship inside the loop. Next week is big ahead Full map below for arc rails👇
