Robinhood debuts Arbitrum-based Robinhood Chain as Solana rolls out on-chain governance requiring 100,000 SOL to propose changes
Robinhood launched “Robinhood Chain,” a public Layer-2 blockchain built on Arbitrum (ARB), on July 3, targeting tokenized real-world assets and decentralized finance applications. Also on July 3, Solana (SOL) formally introduced an on-chain governance proposal system that requires validators to have at least 100,000 SOL staked to put forward protocol changes. Both moves were described as infrastructure-level rollouts rather than concept announcements or testnet launches. The article noted ARB as the underlying technology dependency and said SOL rose 5% that day.
