Circle’s EVM-compatible Layer 1 blockchain Arc officially opened its mainnet, drawing active trading in token-launch platform coins and Arc-native meme tokens. ARC Screener recorded about $127 million in 24-hour volume across the network’s 500 largest tokens, compared with approximately $57.91 million in on-chain liquidity, 767,000 transactions and roughly 30,200 listed tokens. Argus and Tolly accounted for about $21.97 million and $9.12 million of volume, respectively, while rising 915% and 679%; some tokens gained more than 10,000-fold. The concentration of trading in newly listed, volatile tokens, alongside low market capitalizations and liquidity among popular assets, points to elevated price swings and slippage risk. Earlier GMGN data showed ARGUS reaching a $35 million market capitalization before retreating to $23 million, TOLLY peaking at $25 million before falling to $15 million, and LONG reaching $17 million before declining to $12 million. Polymarket assigns a 20% probability to an Arc token launch this year, while @poly_beats identified a leading smart-money address with a Yes position equal to 12.20 times its median wager.
