[Robinhood and Arbitrum Collaborate to Launch On-Chain Trading Platform Rialto, Supporting Cryptocurrency, Stocks, and ETF Trading] BlockBeats News, July 3, Robinhood Crypto, Arbitrum, and Offchain Labs have partnered to build a new on-chain spot trading platform, Rialto, with the goal of 'rebuilding on-chain capital markets.' Driven by PropAMM (Proprietary Automated Market Maker), the Rialto platform focuses on the integration of cryptocurrency and traditional finance, supporting spot trading for various assets including cryptocurrencies, stocks, ETFs, commodities, Pre-IPO assets, and more. Self-custodied equities can be directly used as collateral for third-party lending, stablecoins can flow into broad-based indices in real-time, and Pre-IPO assets can achieve 24/7 trading. Rialto will operate its proprietary PropAMM 'Rivo Altus' to provide foundational liquidity while introducing other market makers and institutional liquidity providers. Initially, the platform will launch with over 90 tokenized Robinhood stocks and mainstream crypto assets. [Original Link]
