What is Robinhood?

Introduction

Robinhood is best known as the mobile app that made trading stocks, options and cryptocurrencies commission-free and accessible to everyday investors. In recent years the company has expanded well beyond its original brokerage role: on 1 July 2026, at its "The World is Flat" event in London, Robinhood launched its own blockchain – Robinhood Chain – a Layer 2 network built on top of Ethereum that aims to bring tokenized stocks, DeFi products and AI-agent trading under one roof.

This guide first walks through Robinhood's history as a company and app, but focuses primarily on what Robinhood Chain is, how it works technically, and the risks and opportunities involved. If the basic concepts of crypto are still new to you, we recommend starting with the crypto investing basics and browsing the crypto glossary.

Robinhood as a company – a brief background

Robinhood Markets, Inc. was founded in April 2013 in Menlo Park, California. Its founders Vladimir "Vlad" Tenev and Baiju Bhatt met as maths and physics students at Stanford University and had previously built high-frequency trading software for financial firms in New York through their earlier companies, Celeris and Chronos Research. After seeing how cheaply large Wall Street players could trade compared with retail investors, the pair decided to build a mobile app that removed trading commissions entirely.

Robinhood went public in July 2021 (Nasdaq: HOOD) and has since grown into a major fintech company:

• Roughly 28 million users across more than 30 countries
• 2025 revenue of around $4.47 billion and net income of about $1.88 billion
• Main revenue streams: payment for order flow, interest income on client cash and margin lending, crypto trading fees, and Robinhood Gold subscriptions

Robinhood has also attracted criticism and regulatory scrutiny, most notably during the 2021 GameStop episode, when the company restricted trading in certain stocks amid extreme volatility. It also has a long history of offering cryptocurrencies such as Dogecoin as part of its product line-up – in Q2 2021, as much as 62% of Robinhood's crypto revenue came from Dogecoin alone.

Robinhood Chain – a new blockchain on top of Ethereum

Background and launch

Robinhood announced its plans to build its own blockchain in June 2025. The public testnet went live on 10 February 2026 and attracted roughly four million transactions in its first week as developers and institutional partners tested wallets, bridges and tokenized equities.

The production network (mainnet) launched on 1 July 2026 at the "The World is Flat" event held at London's Old Royal Naval College. Robinhood's stock (HOOD) rose more than eight percent following the announcement. Three weeks after launch the chain already had around $257.4 million in total value locked (TVL) and processed roughly $4.5 billion of decentralized exchange volume over a seven-day period – higher figures than many networks that have been running for years. Real-time Layer 2 data is available at, for example, L2Beat.

Technical architecture

Robinhood Chain is built on top of Arbitrum's Orbit tech stack (Arbitrum Nitro) and operates as an optimistic rollup Layer 2 on Ethereum. In practice this means:

• Sequencing: A single sequencer operated by Robinhood receives and orders transactions. Ordering is strictly first-come, first-served, so no one can jump the queue by paying a higher fee.
• Speed: Block times are roughly 100 milliseconds, enabling near-instant "soft" confirmations for users.
• Finality: These soft confirmations are not final at the Ethereum layer, however. In the optimistic rollup model, all batched state transitions are assumed valid unless challenged during a fraud-proof window of roughly 6.4–7 days.
• Data availability: Transaction data is posted to Ethereum via EIP-4844 blobs, which have significantly reduced Layer 2 data costs compared with earlier solutions.
• Validators: State commitments are verified by validators, but the set is currently permissioned rather than fully decentralized – Robinhood chooses who is allowed to operate as a validator.
• Gas and fees: The network's gas token is ETH, not a separate Robinhood token. This is an unusual choice for a corporate-led Layer 2, which typically launches its own gas token. Transaction fees are made up of two components: a Layer 2 execution fee and a Layer 1 data-publishing fee to Ethereum. Robinhood has covered gas costs for eligible Robinhood Wallet users during the first 90 days after launch.
• Developer-friendliness: The network is EVM-compatible and fully permissionless for application development – anyone can deploy Solidity or Vyper smart contracts using standard tools (Foundry, Hardhat) without Robinhood's approval. It also supports ERC-4337 account abstraction, allowing, for example, gas-fee sponsorship. The mainnet chain ID is 4663; the testnet is 46630.

Stock Tokens – tokenized equities

The flagship product of Robinhood Chain is Stock Tokens: on-chain tokens that track equities (for example Nvidia, Apple, Google and Tesla) and can be traded 24/7 – unlike traditional stock exchanges with limited trading hours. The tokens are available through Robinhood Wallet in more than 120 countries, though availability varies by jurisdiction.

On the practical side, Stock Tokens can still be used as trading collateral and deposited into DeFi lending pools, blurring the line between a traditional listed share and a programmable, on-chain financial instrument.

DeFi ecosystem and Robinhood Earn

Robinhood Chain launched with a mature DeFi infrastructure already in place, including:

• Decentralized trading via Uniswap (which deployed its own AMM pool as the chain's primary liquidity venue), Lighter, 1inch, Arcus (built by the former dYdX team) and Rialto
• Robinhood Earn, a lending product offering around 7% APY on the USDG stablecoin
• Infrastructure partners including Alchemy, Allium, Chainlink, LayerZero and TRM (the latter providing compliance and monitoring tools)
• Third-party bridging routes through LayerZero, Stargate, Chainlink CCIP, Relay, Across, LiFi and 0x

AI agents – an "AI-native" blockchain

Robinhood describes Robinhood Chain as an "AI-native" network. In June 2026 the company launched agent-based trading (Agentic Trading) for stocks and options in the United States, with equivalent functionality for digital assets (Agentic Accounts) planned for later. The idea is that users can authorise AI agents to trade, swap and lend tokenized real-world assets on their behalf without constant human intervention.

How decentralized is Robinhood Chain really?

Although Robinhood markets the chain as a "permissionless" network, this applies primarily to application development and user access. On the core infrastructure side, the network contains several centralized elements:

• A single sequencer operated by Robinhood
• A permissioned validator set
• Compliance filtering at the sequencer layer (for example sanctions list checks)
• System contracts that can be upgraded without delay

On the security side, however, Robinhood Chain inherits a significant portion of its security from Ethereum: all data is posted to Ethereum, and any observer can in principle challenge an invalid state commitment during the dispute window. The dependence on Robinhood's infrastructure is clearly greater than in fully decentralized Layer 1 networks such as Bitcoin or Solana.

Robinhood Chain vs. other Layer 2 networks

Robinhood Chain competes in the same field as other corporate-led Ethereum Layer 2 networks, the best-known peer being Coinbase's Base. Both are optimistic rollups with a seven-day dispute window, but they are built on different tech stacks: Robinhood Chain uses Arbitrum's Orbit stack, while Base uses Optimism's OP Stack. In late July 2026 Robinhood Chain overtook Base in daily active users – although much of the growth has come from memecoin activity rather than tokenized equities.

This is directly linked to the network's open nature: because anyone can deploy a token without approval, the chain does not technically distinguish a tokenized Nvidia share from a community-launched memecoin. The phenomenon crystallised when a memecoin exploiting Robinhood's original, discarded corporate name "CashCat" reached a market cap of around $156 million shortly after launch. For a more detailed comparison of scaling solutions, see our guide to the Layer 2 comparison.

Risks and things to keep in mind

Summary

Robinhood has grown from a commission-free mobile app into one of the most notable bridges between traditional finance and blockchain technology. Robinhood Chain represents the company's strategic shift from securities broker to on-chain financial-infrastructure provider: it brings tokenized equities, DeFi products and AI-agent trading under one Ethereum-based network.

Technically, the design is a familiar and well-tested one – an optimistic rollup based on Arbitrum's Orbit technology – but the novelty comes from who is holding the reins: a brokerage with 28 million users, direct access to its customer base and a ready-made product pipeline for tokenized real-world assets. At the same time the network contains meaningful concentrations – a single sequencer, permissioned validators and upgradeable system contracts – that set it apart from fully decentralized blockchains.

As with any new financial technology, it pays to do your own research and understand both the opportunities and the limitations before committing capital or using the products – especially when it comes to legally complex products such as tokenized equities.
