Arbitrum (ARB)

Now that @RobinhoodApp Chain is live, one of the more intriguing launches to watch is @rialto_xyz.

Rialto is positioning itself as a new onchain spot exchange built around a PropAMM model, designed to push “deep liquidity onchain” across:

- Spot crypto
- Equities (via Stock Tokens)
- ETFs
- Commodities
- Pre-IPOs
- Basically anything along the spectrum

FYI, PropAMM is an onchain market maker that actively prices and provides liquidity using its own logic and its own inventory, rather than relying on passive, crowdsourced liquidity like traditional AMMs.

At the core is Rialto’s own PropAMM, “Rivo Altus,” which brings orderbook construction, inventory management, and protective execution logic directly onchain.

That gives market makers a much larger sandbox for active trading, while maintaining reliable baseline liquidity across every listed market. On top of that, they’ll plug in external market makers alongside Robinhood Chain’s institutional liquidity providers.

And because DeFi is open and composable
