On the day Robinhood Chain launched, HOOD's stock price rose 8%. Robinhood, with its Arbitrum-based stock token trading platform and on-chain ecosystem, allows traditional brokerages to formally enter the realm of self-built on-chain infrastructure. The core of this event lies in the fact that brokerage traffic, on-chain stocks, wallets, and potential DeFi yields, perpetual contracts, and AI Agent trading are all placed on the same chain, vertically integrated within the industry chain. Robinhood officially disclosed that it serves nearly 28 million customers in 38 countries across three continents, making Robinhood Chain's distribution capabilities different from typical L2. Robinhood Chain experienced significant growth in its initial phase. According to official and executive disclosures, within about a week of launch, it achieved 17 million transactions, nearly 350,000 addresses, approximately $250 million Protocol TVL, and over $1 billion in cumulative DEX trading volume. Latest data shows that the equity token is still in its early stages, valued at tens of millions of dollars, with a notional market capitalization of approximately $17.90 million. Trading activity is concentrated in a few popular assets such as $NVDA. This report provides a systematic overview of the Robinhood Chain ecosystem, from its underlying architecture to its ecosystem map, and explores a more fundamental question based on the actual performance of on-chain data: Where will the next evolution of internet brokerages lead? Positioning and Underlying Architecture Robinhood Chain is an Ethereum L2 platform built on the Arbitrum technology stack by the US internet brokerage Robinhood, using a Rollup model. It is a Layer 2 platform designed according to institutional standards for tokenized real-world assets (RWA) and tokenized stocks, targeting RWA and AI-native applications. According to the official documentation, its main technical framework is as follows: **Technical Parameters:** Chain ID: Mainnet chain ID 4663 / Testnet 46630. Robinhood Chain achieves a 100ms block time, inherits Ethereum-level security, and adopts a native permissionless architecture. It supports arbitrary message passing (AMP) between Ethereum L1 and Robinhood Chain L2, i.e., it has L1/L2 cross-chain messaging and bridging mechanisms. Data Availability: This chain uses Ethereum blobs for data availability (DA) and inherits Ethereum's security. Gas Token: This chain uses ETH as its native gas token. The absence of a native token means there is no tokenized economic incentive layer; value capture directly falls to the parent company (HOOD stock price) and Arbitrum (profit sharing), which is a key difference from most corporate blockchains. Transaction Fees: Robinhood Chain posts its data to Ethereum's L2, so a transaction fee consists of two parts: L2 Execution Fee: The cost of executing a transaction on Robinhood Chain. It operates similarly to Ethereum's Gas fees, and is relatively inexpensive and stable. L1 Data Fee: The cost of publishing transaction data to Ethereum to ensure data availability. This fee fluctuates depending on Ethereum network congestion and is proportional to the size of the calldata in the transaction. Transaction ordering mechanism: Robinhood Chain uses FCFS (first-come, first-served), ordering transactions by the time they arrive at the sequencer. Robinhood Chain performs compliance screening at the sequencer level, meaning some transactions may be filtered or have their execution affected before entering the ordering or execution process. (*FCFS is a type of MEV that reduces public gas bidding, but does not eliminate MEV. Ordering power is concentrated in the sequencer. Fairness mainly depends on the sequencer operator itself enforcing FCFS. Theoretically, the sequencer still sees the transaction flow first and can delay, rearrange, insert, or censor transactions.) Protocol Revenue: 10% of net protocol revenue goes to Arbitrum, 8% to the DAO, and 2% to the Developer Guild. Under the Arbitrum Expansion Program, approximately 10% of net protocol revenue flows back to Arbitrum. This was a direct catalyst for ARB's surge after the mainnet launch—the market priced it as a "L2 revenue-sharing template." From the fee audit in mid-July, Arbitrum takes about 10% of the fees flowing back to Ethereum, while Ethereum captures less than 0.2% of the value. Platform Features: Planned support for DeFi composability, 24/7 self-custody, and DeFi support and accessibility. The actual implementation depends on the whitelist, risk control, and regulation. Based on the official ecosystem partners and related data, the chain's ecosystem mainly presents a combination of self-built flagship assets and external protocol access. We have organized it into layers as follows: src="https://img.jinse.com.cn/7493240_image3.png" title="7493240" alt="L4uTjOe5O28wJB1cBb747FedMAOzqReL364jpEC8.png">



Robinhood Chain's DEX trading volume experienced explosive growth after July 8th, reaching a peak on July 11th.

The latest protocol TVL breakdown shows that Robinhood Chain's core TVL remains lending, DEX, derivatives/bridges, and yield. Morpho Blue currently has a TVL of approximately $156.8M, making it the largest single protocol; Uniswap V2/V3/V4 combined has approximately $75.6M; Arcus Perps, Spark Savings, and Lighter Bridge have also entered the tens of millions of dollars level.
The latest protocol TVL breakdown shows that Robinhood Chain's core TVL remains lending, DEX, derivatives/bridges, and yield.

Due to potential differences in terminology and double counting between protocol TVL aggregation and Chain TVL, a more reasonable understanding is that: Morpho is the main source of funds, Uniswap is the main trading platform, and stablecoin yields and derivatives form the second growth curve. ...>
The growth of TVL (Total Value Chain) is not just about the expansion of DEX LP pools, but also includes the accumulation of stablecoin settlement assets and yield funds. In DeFiLlama data, the stablecoin supply page is the foundation of the chain's important sustainable activities.

Among them, USDG has become the foundation of on-chain funds, and its expansion is particularly crucial. It is both the underlying narrative asset of Robinhood Earn and a major part of Morpho's lending and stablecoin yield strategy. ...center">
