WHY ROBINHOOD CHOSE ARBITRUM

Summary from the TLDR Crypto newsletter

Robinhood announced that tokenized stocks will trade on Arbitrum One and later a custom chain built on Arbitrum's tech stack. The reasons for this decision include wanting production-ready infrastructure and easier access from traditional developers via Arbitrum's Stylus technology. Solana does not allow Robinhood to easily capture value, which they can do via sequencer fees with an L2.
