Nothing that Robinhood Chain already provides gets rebuilt here; Icaria is designed to work with it. Each integration below sits either inside the settlement path or in the services around it. ## Chainlink **Role:** pricing, market status, sequencer status, and a possible policy engine for eligibility. Data Feeds and Data Streams supply 24/5 equity pricing with the ERC-8056 multiplier already applied, alongside the `marketStatus` field the regime engine runs off. What drives the post-outage grace is the Sequencer Uptime Feed. Treasury and gold listings on the [Asset roadmap](/assets/asset-roadmap.md) will bridge over CCIP. Should Chainlink ACE and CCID reach general availability on chain 4663, they become a candidate adapter for the eligibility registry. See [Oracles and market sessions](/risk/oracles.md). ## Paxos and USDG **Role:** quote asset. Native to the chain, regulated under MiCA, and already the dollar behind the chain's lending markets, USDG is what traders turn up holding. Co-marketing with Paxos forms part of the go-to-market plan. See [Quote asset: USDG](/assets/usdg.md). ## Aggregators, Uniswap and 1inch **Role:** arbitrage flow, and distribution through aggregators. Uniswap v2, v3 and v4 and 1inch are all deployed here. Arbitrageurs pulling generic pools back toward Icaria's anchored quotes are flow the venue wants, and skew pricing pays them for rebalancing vaults along the way. Plugging into aggregators through the public router interface is a distribution goal in itself: wherever the anchored quote wins, the routed flow follows. ## Morpho Blue **Role:** the chain's lending layer, and a natural source of flow. Morpho runs the chain's USDG lending markets, somewhere around $80M to $90M of RWA deposits sitting behind Robinhood Earn. Lenders and borrowers rotating between yield and Stock Token exposure are exactly the flow a swap venue exists to serve. ## Account abstraction providers **Role:** onboarding without gas, and batched transactions. ERC-4337 entry points and EIP-7702 are both available. Alchemy Account Kit handles embedded accounts and gas sponsorship on the front-end, with ZeroDev as the fallback. One user operation covers a first swap: Permit2 approval and swap together, with gas sponsored. Smart accounts sign RFQ quotes through EIP-1271. ## Robinhood Wallet **Role:** the trader's primary wallet. Deep links from the front-end point into Robinhood Wallet, and getting listed in that wallet's dApp directory is a distribution target, since the venue's first audience is whoever self-custodies Stock Tokens outside the Robinhood app. ## Blockscout **Role:** transaction transparency. Inside the trade explorer, fills, parameter changes and fee accruals all link out to their transactions on Blockscout. ## TRM Labs **Role:** sanctions and AML screening. TRM runs at the chain's sequencer level. Independently of that, the KYC provider issuing Icaria's eligibility attestations screens at attestation time and again at renewal, which makes two distinct layers. ## Indexing Ponder, self-hosted in TypeScript, or Envio HyperIndex over chain 4663 powers the trade explorer, the execution-quality dashboards and the keeper service. See [Off-chain services](/architecture/off-chain-services.md). ## Arbitrum ecosystem An Arbitrum Orbit chain is what Robinhood Chain is. Applying to the Arbitrum Foundation for audit subsidies is on the plan, as is taking part in the Arbitrum Open House 2026 buildathon track and in Chainlink BUILD. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.useicaria.xyz/robinhood-chain/ecosystem.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
