Arc is set to launch its mainnet on Sept. 16, but the fight for liquidity has already started. Ahead of the rollout, USDC on Arc-related markets has been trading at a premium, with some participants even buying the stablecoin over the counter in an effort to position before trading opens.
A large part of that frenzy stems from the meme-fueled wealth effect previously seen on Robinhood Chain. With the market looking for the next traffic hub, Arc — backed by Circle and surrounded by a Wall Street-heavy narrative — has moved into focus.
Arc’s ecosystem race is underway before the chain is even live
Arc’s long-trailed mainnet launch is now set for Sept. 16.
At a time when more public chains have gone through reshuffling and, in some cases, faded from view, Arc has attracted unusual attention from the start. Circle, the issuer of USDC, is building Arc as a public blockchain centered on stablecoins and financial infrastructure. Unlike many new chains that need to cultivate users and liquidity from scratch, Arc comes with an existing USDC circulation base, institutional relationships and a compliance-oriented story. Those features are widely seen as part of its early edge.
One of the biggest reasons for market attention is Arc’s founding validator lineup. BlackRock, DTCC, Visa, Mastercard, ICE, Standard Chartered, SBI, MoneyGram and Galaxy are all involved, covering key areas across traditional finance including clearing, custody, payments and asset management. A public chain bringing in that many major TradFi names as validators is still relatively uncommon.
Capital markets have also pushed expectations higher. In May 2026, the ARC token completed a $222 million institutional round led by Andreessen Horowitz, or a16z, at a roughly $3 billion fully diluted valuation. BlackRock, Apollo, ICE and ARK also participated. That investor list, paired with the valuation, has helped expand the market’s expectations for Arc.
Even before the mainnet opens, community activity has continued to build. Guides, tutorials and interaction strategies focused on Arc have been circulating widely, and partnership announcements have picked up ahead of launch. Protocols, market makers, wallets and trading venues are taking positions as the countdown to a liquidity and attention battle enters its final stretch.
Arc’s ecosystem already has an early shape. On the DeFi side, Uniswap, Aave, Morpho, Aerodrome, Curve, Euler, Maple and Fluid have announced plans to join. Market makers including FalconX, Galaxy, GSR, Keyrock and Nonco are also in. Wallets and trading platforms such as Binance Wallet, OKX Wallet, Ledger, MetaMask, Upbit and Kraken have announced support as well. Beyond that, Arc’s ecosystem reaches into derivatives, crypto payments, NFTs, oracles and infrastructure.
Launchpads are moving early to capture meme traffic
For any new chain, the real challenge is not simply going live. It is pulling in liquidity, users and attention quickly enough at the start. Robinhood Chain previously used launchpads to ignite a meme wave that drew in capital and users in a short period, turning that approach into a reference point for how a new chain can jump-start activity.
That playbook is now being replicated around Arc.
Launchpads have moved first, trying to secure a piece of the “shovel-selling” business as Arc opens up. The goal is straightforward: control meme traffic and the entry point for early users. Community tallies suggest there are already dozens of token launch platforms in the Arc ecosystem, including Pools, the launchpad platform introduced by Uniswap. At the same time, Fomo APP, a trading terminal popular with meme traders, has announced support for Arc and received a positive response from Circle CEO Jeremy Allaire, adding to market expectations around Arc’s meme segment.
The wealth effect seen on Robinhood Chain has also amplified expectations among retail participants. Some are closely watching the social accounts of ecosystem teams, official members and related institutions in search of clues. Others have prepared capital and trading tools in advance, waiting for the mainnet to open. Some have even paid a premium for USDC in the OTC market in order to secure an early position.
For those traders, Arc’s mainnet launch is not just the arrival of another blockchain. It is an opening window for opportunity, and the fight for attention has already begun.
Arc and Robinhood Chain share some features, but the comparison has limits
Robinhood Chain broke out quickly after launch, powered by meme-driven wealth creation that turned it from a new financial chain into a hot onchain hunting ground. That path is one reason Arc, with Circle behind it, is being treated by some market participants as a leading candidate for the next wave.
The comparison has a basis. Robinhood Chain and Arc are both led by financial companies, and both benefit from their parent companies’ existing users, capital and resources. Robinhood is a brokerage. Circle is the issuer of USDC. Neither chain began as a crypto-native public blockchain built from zero. Both are attempts to move existing financial businesses onto a chain-controlled settlement layer.
They also share a finance-onchain narrative. Robinhood Chain is focused on tokenized U.S. stocks and ETFs, lending and perpetual products. Arc is centered on stablecoin settlement, foreign exchange, tokenized Treasuries, money market funds and institutional payments.
On the technical side, both use EVM architecture. That lowers the barrier for developers and makes it easier for mature Ethereum-based applications and infrastructure to migrate, giving ecosystem projects a path to scale quickly.
Why Arc may struggle to repeat Robinhood Chain’s meme-led start
Still, Arc may find it harder than expected to follow Robinhood Chain’s meme-driven cold start.
One major advantage for Robinhood Chain was Robinhood’s large retail user base. Those users were already familiar with stock trading and were not strangers to high-risk, high-volatility assets, making meme coins a natural first stop in the onchain ecosystem. Just as important, speculative onchain trading did not fundamentally clash with Robinhood’s business model. The more active the trading, the more room the platform had to generate revenue through transactions and fees.
Arc has a different center of gravity. Circle’s goal is to position the network as financial infrastructure built around stablecoins, financial institutions and real-world assets. Its future distribution may come more from payment systems, card networks and asset managers than from users primarily looking to speculate on tokens. For Arc and the institutions building around it, stability, compliance and credibility matter more than maximizing fee income through rapid speculative turnover.
Crypto researcher Haotian made a similar point. In his view, Robinhood Chain’s ability to heat up its ecosystem was tied closely to Robinhood’s brokerage DNA, retail traffic, tokenized stock business and CEO Vlad Tenev’s relatively open attitude toward meme culture. Whether those same conditions exist for Circle remains unclear.
He also argued that before Robinhood Chain, institution-facing chains such as Tether-linked Plasma and Stable, as well as Stripe’s Tempo, were mostly built around stablecoins, payments and settlement. For that category of chain, payment and settlement are the end goal, with compliance and stability taking priority and strategic positioning also playing a part. Robinhood was different. As a brokerage, it naturally put more weight on user traffic, trading activity and business extension.
Arc also departs from the standard public-chain playbook in its transaction design. The network has shut off the public mempool and uses an encrypted mempool instead, meaning outside participants cannot view pending transactions before they are included in a block. That sharply limits common forms of transaction sniping seen on other chains. For traders and infrastructure providers whose models depend on frontrunning, sandwich strategies and MEV extraction, the rulebook changes materially. Those activities are also an important source of revenue for some meme launchpads and trading infrastructure.
Expectations are high, but the real test starts after launch
The meme wealth effect created earlier by Robinhood Chain has already raised expectations across the market. Traders may be looking at Arc with even more excitement, but not necessarily with more patience.
Haotian noted that Arc has not even gone live yet, and the ecosystem already has dozens of launchpads, with some projects beginning to call in “leaders” to rally support. Traders familiar with Robinhood Chain’s early days know that the eventual winner rarely appears at the very beginning. Pons did not rise in a straight line, early projects such as Noxa later faded, and Pools.trade emerged midway through the process. There were many variables.
That means even if Arc eventually produces a true meme leader, the ecosystem will likely go through a round of cleansing first. Haotian’s view is that chasing the first wave of Fomo may be less attractive than looking for the projects that still stand after the mess clears.
For Arc, pulling meme traders onto the chain may be only the first step if it wants to echo Robinhood Chain’s story. The harder question is whether short-term Fomo can be converted into durable users, liquidity and onchain activity. With the mainnet about to open, Arc’s real test may only be starting.
