Etherscan has officially launched RobinScan, a dedicated blockchain explorer for Robinhood Chain, accessible at robin.etherscan.io. The new explorer is built for the network identified by chain ID 4663, bringing Etherscan’s transaction, wallet and smart-contract tracking tools to Robinhood’s expanding Layer-2 ecosystem. Etherscan also introduced API access for the chain, giving developers programmatic access to on-chain data, with a 14-day processing window noted for certain requests.
Robinhood Chain itself is an Ethereum-compatible Layer-2 cross-chain network built on Arbitrum technology, designed for financial applications, decentralized applications and tokenized assets. The explorer launch comes as Robinhood’s on-chain activity is drawing both support and scrutiny. Dragonfly managing partner Haseeb Qureshi and Uniswap founder Hayden Adams defended the network after critics pointed to a sharp drop in fee revenue. Qureshi said the decline reflected a deliberate gas limit increase and fee reduction, not fading demand, and argued Robinhood Chain is “solidly #2 behind Solana.” Adams added that the chain simply “scaled up capacity to meet massive blockspace demand.”
On-chain data supports a still-active ecosystem: Robinhood Chain recorded about $403,000 in revenue and $448,600 in fees over 24 hours, alongside $1.81 billion in DEX volume, with more than $12.77 billion over seven days, up nearly 23% week over week. Total value locked has climbed above $937 million, and stablecoin market capitalization has passed $1 billion, led by USDG at over 68% of the float. However, Solana Labs co-founder Anatoly Yakovenko offered a more skeptical view, arguing that a cheap L2 may be a low-margin business for Robinhood and could benefit rival front ends.
The network’s ties to Arbitrum and Uniswap are notable. Uniswap reportedly keeps 0.465% of every dollar traded on Robinhood Chain — more than double its 0.214% rate elsewhere — because tokenized stocks trade in its priciest fee tiers, and those fees feed UNI’s buy-and-burn mechanism. Arbitrum, whose technology underpins the chain, receives 10% of net protocol revenue, with 8% going to the Arbitrum DAO treasury and 2% to a developer fund. Standard Chartered has begun covering ARB with a forecast of $10 by the end of 2030, compared with around $0.147 today, citing Robinhood Chain’s potential to make Arbitrum “the number 1 choice for TradFi when bringing assets on-chain.”
