BlockBeats News, July 3rd, Robinhood Crypto, Arbitrum, and Offchain Labs announced a partnership to build a new on-chain spot trading platform called Rialto, aiming to "rebuild the on-chain capital market." The Rialto platform is powered by PropAMM (Proprietary Automated Market Maker), focusing on the integration of crypto and traditional finance. It will support spot trading of cryptocurrencies, stocks, ETFs, commodities, Pre-IPOs, and various assets. Self-custodied equities can be directly used for third-party lending collateral, stablecoins can flow in real-time into broad-based indices, and Pre-IPO assets can be traded 24/7.

Rialto will operate its own PropAMM "Rivo Altus" to provide base liquidity and will also onboard other market makers and institutional liquidity providers. In the initial phase, it will list 90+ Robinhood tokenized stocks and mainstream crypto assets.
