Robinhood Chain, an Ethereum layer-2 network built with Arbitrum technology, saw total value locked (TVL) increase 213x from $4.5 million to $960 million in under two months, according to Artemis data. Standard Chartered described the rise as the fastest blockchain growth it has seen. Arbitrum’s dashboard, arbdata, subsequently reported that TVL had surpassed $1 billion. The milestone came less than a year after the network’s public mainnet launch and reflects growing activity across self-custody wallets, token swaps, lending protocols, decentralized exchanges and other applications. Early adoption was driven mainly by memecoins and stablecoin deposits, while Robinhood Chain’s connection to Robinhood’s 23 million funded customers could support further DeFi adoption.
