A chain suits securities-backed lending only if it clears three bars. The collateral must be a standard ERC-20 that holders keep in their own wallets. A regulated entity must stand behind it. Chainlink must price it. Robinhood Chain clears every one, and adds an advantage competitors cannot copy: the broker that issues the collateral is also the one that distributes it to its holders. The evidence follows below. ## Point by point The sources are Robinhood's own published documentation and Arbitrum Foundation material. ### Collateral and prices | Area | On Robinhood Chain | Value to Spatial | | ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------- | | Native RWAs | **Stock Tokens**, which are 18-decimal ERC-20s from Robinhood Assets (Jersey) Ltd, backed 1:1 by shares in US custody and sold across 120+ countries | Collateral issued directly by a listed broker | | Corporate actions | ERC-8056 `uiMultiplier()`: dividends are reinvested and splits become a shares-per-token ratio | The collateral compounds without help, and dividends never leak out of escrow | | Oracles | Chainlink Data Feeds running 24/5; Data Streams on the v11 RWA schema with its `marketStatus` field; CCIP; the Sequencer Uptime Feed; the multiplier is included in every price | Production-grade pricing from day one | | Stablecoins | USDG (Paxos, regulated under MiCA), native, and what Robinhood Earn lends out through Morpho; USDe live; USDC via CCTP *unconfirmed* | The currency loans are made in | | Token-level compliance | **Nothing at token level**: no allowlist or transfer hook on Stock Tokens; Robinhood enforces eligibility in its interface and at issuance and redemption, which require KYC | Spatial runs its own eligibility checks where users enter the protocol | ### Infrastructure | Area | On Robinhood Chain | Value to Spatial | | -------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------- | | Stack | A dedicated Arbitrum Nitro (Orbit) chain in rollup mode; settles on Ethereum with data in blobs; canonical withdrawals take 7 days | Security from Ethereum and Arbitrum tooling with no changes needed | | Status | Chain ID 4663, on mainnet since 1 July 2026; about $540M TVL in mid-August 2026, though reported figures range from $536M to $1.4B | A live network with real users and real assets | | Deploying | Permissionless, EVM-equivalent; Solidity or Vyper using Foundry or Hardhat, plus Stylus for Rust and WASM | No permission needed to ship; signature verification is in Solidity now, and Stylus is an option for a cheaper batch verifier | | Speed and cost | Blocks roughly every 250 ms, 100 ms with preconfirmations; a typical transaction costs about $0.001 (median); ETH pays for gas | Quick originations and liquidations, and filling twenty offers at once remains inexpensive | | Sequencer | Robinhood runs one sequencer, ordering first come first served and screening for sanctions; if it censors, the L1 delayed inbox lets transactions in once 24 hours pass | Spatial is designed to withstand a full day of downtime, and can read sequencer status from a Chainlink uptime feed | | Smart accounts | EIP-7702 plus ERC-4337 EntryPoints from v0.6 up to v0.8 (ArbOS 40), served by Alchemy Gas Manager and ZeroDev | Gas-free onboarding, approve and borrow in a single batch, and offer signatures via EIP-1271 | | Existing DeFi | Morpho Blue; Uniswap in versions 2, 3 and 4; 1inch, Lighter and Arcus | Somewhere for unmatched capital to wait, plus liquidity that auctions can clear into | | Economics | 10% of net chain revenue goes from Robinhood to the Arbitrum DAO, and Robinhood also committed $1M to sponsor Arbitrum Open House 2026 | Grants and audit subsidies are open to builders | ## The alternatives * **Solana.** Stocks tokenised on Solana (Kamino, Jupiter Lend) live in pooled markets with strict caps, and they come from third-party issuers rather than from the broker whose customers own the shares. * **Base.** Coinbase launched tokenised stocks on Base on 24 August 2026. They are new, and no lending stack has formed around them so far. * **Ethereum mainnet.** It has the deepest DeFi anywhere but no broker-issued equities of its own, and its gas costs make a twenty-lender syndicate unviable. Robinhood Chain is the only place that combines the assets, the feeds, the loan currency, cheap fees and account abstraction, all backed by the distribution of the broker that issues them. ## Gaps Spatial fills An honest case names what is missing. Three things are, and Spatial handles each. 1. The chain does not restrict who can hold a Stock Token. For Spatial, the [permission registry](/inside-the-protocol/eligibility.md) takes on that job. 2. The chain offers users no protection when the sequencer halts. Spatial offers the delayed-inbox route plus a grace period before liquidation, described in [Sequencer outages](/risk-and-safeguards/sequencer.md). 3. The chain does not handle the price gap that builds up while markets are shut. Spatial uses haircuts that depend on the trading session; see [pricing and sessions](/risk-and-safeguards/pricing.md). --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.onspatial.org/the-network/the-case-for-robinhood-chain.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
