Arcfun

Launching ideas into communities on Arc.

Built for builders. Powered by fun.

[Arcfun @arcfunapp]

arcfun is live on @arc mainnet.

the contracts are deployed, source-verified, and the platform is open. $ARCFUN, the official arcfun project token, is now live.

every launch has a fixed 1b supply, no presale, no team allocation and no mint authority. price discovery runs on a USDC bonding curve, with automatic Uniswap V4 migration at a $25k market cap and $7k in permanently locked liquidity.

creators earn 0.5% of every trade, before and after migration.

built for arc. live from day one.

liquidity can be locked while most of the supply sits in a few wallets.

we show holder distribution on arcfun because users need both pieces. a useful rating would explain those risks and let people check the evidence.

[Sam | Arc and Circle Dev Community @samconnerone]

Someone should build a trusted rating system for DeFi protocols and tokens….something that helps everyday users understand risk before allocating capital.

Security, liquidity, decentralization, audits, token concentration, protocol history, governance, yield sustainability, etc.

Risk is part of investing and it should be informed and calculated.

participation and visibility have really picked up over the last two days, so we’re extending the arcfun art & content contest by 5 days.

$700 for 1st place. $200 for 2nd.

if you’ve been working on an entry, you’ve got more time to get it out there.

[Arcfun @arcfunapp]

arcfun art & content contest. $900 in prizes.

@arc’s commitment to supporting builders inspired us to back another part of the ecosystem: the creators helping people discover what’s being built.

we’re opening a 7-day contest for arcfun artwork.

1st place: $700
2nd place: $200
how to enter:

follow @arcfunapp on X and repost this announcement. both are mandatory.

publish a post on X featuring your arcfun artwork. images and videos both qualify.
mention @arcfunapp and clearly identify it as a contest entry.
submit your post link here.
only entries completing all four steps will qualify.

the two entries with the strongest overall organic reach and engagement win. results will be assessed 7 days after this announcement is published. botted or purchased engagement will disqualify an entry.

organized and funded independently by arcfun.

entries are open.

[Arcfun @arcfunapp]

your token can go up 20% and still leave you down 4%.

if it gains 20% against eth while eth falls 20% in dollars, that’s your result before fees.

arcfun launches trade against usdc. keeping score shouldn’t require a second chart.

https://t.co/8HLLHkYKL5

[Arcfun @arcfunapp]

agents need to justify their research budget too.

on arc, data, gas and arcfun trades can all be paid for in usdc. that makes it easier to see whether an agent’s decisions are worth what it spends making them.

[Arc @arc]

Agent-ready services are now live on Arc through Circle Agent Marketplace.

Agents can search the live web, access real-time market data, enrich leads with people and company intelligence, and use more services through Circle Agent Stack.

Pay per call in USDC.

[Arcfun @arcfunapp]

the best part of this contest is seeing what arcfun looks like in someone else’s head.

nice work, @0x_zyven. what are the rest of you working on?

[Arcfun @arcfunapp]

@samconnerone @circle @the_tq 💪💪💪

[Arcfun @arcfunapp]

someone can love your project and still get stuck trying to fund a wallet.

yesterday’s @arc guide on onramp kit shows how builders can embed USDC funding through cards, apple pay and google pay, where supported.

we built arcfun around USDC. making that first balance easier to get could help creators bring in people who have never used a launchpad.

there are whole communities outside crypto. we should be building with them in mind.

https://t.co/VTGRZMQdeV

[Arcfun @arcfunapp]

$629.64m in stablecoins on arc. $42.49m traded on dexes in 24h.

if you’re building here, that’s a serious market to build for.

which arc app are you already coming back to every day?

[Arcfun @arcfunapp]

$30.8m in cirBTC on arc already.

what would make those holders open an arc app every day? that’s a product worth building.

[Sam | Arc and Circle Dev Community @samconnerone]

I love cirBTC on Arc

Arc is putting $1m behind its next wave of builders.

when their ideas need a token, Arcfun is already live.

[Arc @arc]

What will you build on Arc?

We’re giving up to $1M to eligible teams building exceptional projects on Arc, from payments and FX to lending, asset tokenization, and agentic workflows.

Arc Mainnet is live. The platform is ready. Now it’s time for builders.

the internet went global decades ago. value is finally catching up.

[Sam | Arc and Circle Dev Community @samconnerone]

Building beyond Borders

Happening in real time this is so amazing ❤️🙌🏾

[Arcfun @arcfunapp]

day two:

$339.3m TVL
$655.9m in stablecoins
$58.8m in DEX volume

Arc didn’t arrive asking for liquidity. it arrived with liquidity.

we know where we’re building.

[Arcfun @arcfunapp]

@samconnerone exactly. the end state is users choosing products, not chains, while liquidity moves underneath.

[Arcfun @arcfunapp]

Arc Studio may become one of the most important pieces of Arc’s growth loop.

Not because “AI can code.” Everyone has heard that pitch.

Because every new ecosystem faces the same problem: people arrive with ideas, but most of those ideas never become working products. Too much time is lost assembling wallets, contracts, backend logic, protocol integrations and test environments before a user can touch anything.

Arc Studio attacks that gap directly.

Describe an idea in natural language and it can generate a working full-stack prototype with frontend, backend and smart contracts. The code is exportable, inspectable and can be developed further inside existing workflows like Codex, Claude Code and Cursor.

More importantly, Studio understands the Arc and Circle stack. It is built around actual onchain primitives such as CCTP, Gateway, Wallets and USDC flows, not generic abstractions awkwardly forced onto a blockchain.

That matters to us at Arcfun.

Launchpads do not create ecosystems by themselves. Builders do.

Our role begins when one of those builders has a real reason to launch an asset and needs an open market around it.

On Arcfun, anyone can launch through a USDC-denominated bonding curve. Supply is fixed. There is no presale, no team allocation and no privileged minting. Price discovery happens onchain from the first trade, and successful launches automatically migrate into permanently locked Uniswap V4 liquidity.

Arc Studio lowers the cost of turning an idea into an application.

Arcfun lowers the cost of turning an asset into a live market.

This does not mean financial code should move from a prompt straight into production. Arc is explicit that generated code must still be inspected, tested and independently validated. That is the correct approach.

The opportunity is not removing engineers or skipping security. It is removing weeks of repetitive setup so builders can spend more time on the part that actually matters: finding out whether people want what they are building.

If Arc can shorten the path from idea to prototype, while infrastructure like Arcfun makes the path from token to market fairer and more transparent, the result is a powerful ecosystem loop:

more experiments
faster feedback
more products
more communities
more markets

This is how an ecosystem becomes dense.
Not through one giant application, but through hundreds of ideas being shipped, tested and allowed to earn attention on their own merits.

Arc Studio is opening the door for the next wave of builders.

Arcfun is already live for what they create next.

[Arcfun @arcfunapp]

@Mars_DeFi 💪

[Arcfun @arcfunapp]

we’re applying.

arcfun is already live on arc: a usdc-native launchpad with fully onchain price discovery and automatic uniswap v4 migration.

we have more ideas for it than hours in the day. time to pick the next one and ship. 💪

[Arc @arc]

Arc Microgrants is for early thinking and vision.

The side project. The prototype. The tiny app. The proof of concept you built because you wanted to see if it could work.

We’re awarding 20 microgrants of $500 USDC to eligible early builders shipping working mini apps on Arc Mainnet.

Submissions close October 14.

Details and Apply: https://t.co/0wV2pXCESj

[Arcfun @arcfunapp]

day two and @arc is already putting up to $1m behind its builders.

yeah, we picked the right chain.

[Arc @arc]

Arc Mainnet is live. Now look up.

Tonight, 850 drones will illuminate the San Francisco skyline above the Ferry Building, telling the story of Arc, the Economic OS for the internet.

The show points to what comes next: up to $1M for eligible teams building on Arc.

Fast settlement. USDC-powered transactions. Agentic payments. Builders around the world.

Watch live on X tonight.

[Arcfun @arcfunapp]

@samconnerone architects, what are we launching first?

[Arcfun @arcfunapp]

all these architects are going to need a launchpad.

[Sam | Arc and Circle Dev Community @samconnerone]

Built different.

Building everywhere.

We’re building toward the largest, most connected global network of founders and developers.

Chapter by Chapter.

Real relationships, shared ambition..

We are Architects
