[Arc Chain Launchpad Long Responds to Criticism: Stock Tokens on Arc Correspond 1:1 to Robinhood Holdings, Discount Due to USDC Premium] BlockBeats News, September 14 — Arc Chain Launchpad Long addressed some community concerns about its project in a post on Platform X. It stated that the stock tokens issued on Arc are backed 1:1 by real stocks held in custody on Robinhood, which can be verified on-chain via the cross-chain treasury and are exchangeable 1:1 with Robinhood Chain. Longdotsupply will serve as the permanent issuer of these cross-chain stocks, ensuring that holders will not need to migrate their tokens in the future. Additionally, the official statement attributed the lower stock prices on Arc to a roughly 2x premium on native USDC on-chain, and noted that the premium will normalize once Arc's mainnet opens cross-chain functionality with USDC on September 16, at which point liquidity will be injected into CRCL/USDC. However, the post did not address other concerns, such as risks associated with the underlying protocol of its cross-chain bridge. In related news, well-known crypto KOL Bonk Guy promoted Arc Chain Launchpad Long, leading to a 27-fold surge in its market cap within a short period. Some wallets that positioned themselves a day earlier saw unrealized profits of hundreds of thousands of dollars. Meanwhile, several community members have raised concerns about significant security vulnerabilities in the protocol. [Original Link]
