Circle's USDC-Settled Arc Chain Logs $410.8 Million in Day-One DEX Volume

Arc Mainnet Opens to Speculators

Circle's Arc, the EVM-compatible layer-1 blockchain the USDC issuer spent months positioning as infrastructure for institutional finance and real-time money movement, went live on mainnet on September 16 — and the market greeted it in the least institutional way imaginable. On-chain data from a Dune dashboard tracking the chain shows the network cleared $410.8 million in decentralized exchange volume and processed 7,763,670 transactions within its first 24 hours. Instead of bond desks and settlement corridors, the dominant users were memecoin traders: launchpad platforms generated $336.3 million of that flow, roughly 82% of everything that changed hands on day one. Circle built Arc as what CEO Jeremy Allaire described as an open, neutral “economic operating system” for the internet, secured by a founding validator set that includes BlackRock, Visa, Mastercard, DTCC and ICE. More than 100 institutions and developers deployed on or tested the network before the public opening, and asset managers including BlackRock, Bitwise and Janus Henderson had already moved tokenized funds onto the chain, while Visa and MoneyGram plan to run stablecoin settlement through it. But the opening-day order flow came from a very different crowd. A single launchpad, arguspad.io, absorbed $202.35 million — close to half the chain's entire volume — and minted 83,751 of the 97,025 tokens created on Arc in 24 hours, a one-day record that outpaces pump.fun's best. Minara.fun followed with $36.41 million, tollylabs.com with $19.65 million and redardex.pro with $13.11 million, spread across 19 active launchpads, with volume falling away sharply beyond the top five.

Robinhood Chain Set the Baseline

Comparisons with other high-profile launches frame how unusual that start was. Robinhood Chain, the tokenized-equities network that has become one of the most-watched chains of recent months, recorded just $568,630 in DEX volume on its own mainnet debut on June 30, per a second Dune dashboard — and needed a little over a week to clear the $581.12 million that Arc moved in a single day, making Arc's opening roughly 720 times larger. Part of the gap is timing. Arc went live with Aave, Morpho and Uniswap smart contracts already running, and with spot access from crypto exchanges including Binance, Kraken and OKX available from the first block — launchpads arrived on a chain with liquidity plumbing already in place. Robinhood Chain's own trajectory shows what typically comes next: speculation first, real assets later. Its risk-weighted assets stood at $168.13 million as of September 17, spread across tokenized stocks, ETFs, commodities and Treasury products, and after a quiet August the chain posted a record $3.7 billion in daily volume this month. Arc's institutional thesis is already visible outside the launchpad economy: roughly $74.6 million of day-one activity sat beyond memecoin platforms, tied to USDC-denominated settlement, tokenized collateral through BlackRock's BUIDL and Circle's USYC, currency swaps via StableFX and enterprise payment channels — a strong opening for any new chain, even before its flagship users arrive.

Sustainability Is Now the Test

Our reading of the on-chain record: September 16 was, above all, a liquidity event. Memecoin activity on freshly launched chains historically surges for days or weeks, then collapses once the first cohort of traders rotates out, and Arc's 82% launchpad share puts it squarely in that pattern. The durable signal is the $74.6 million of non-launchpad settlement — the activity Circle actually built the chain for. If that share compounds while memecoin volume cools, Arc becomes genuine financial infrastructure; if both fade together, day one will stand as a speculative debut rather than a turning point.
