The integrations below fall into two groups: those that sit directly in the origination and liquidation path, and those that surround it. ## Morpho Blue **What it does for Ethosis:** absorbs idle lender capital and backstops liquidation liquidity. Morpho already powers Robinhood Earn and holds roughly $80M to $90M of RWA deposits on the chain. Ethosis parks unmatched lender USDG in a whitelisted Morpho USDG vault and pulls it out just in time when a loan originates. The liquidators and arbitrageurs who already serve Morpho are obvious bidders in Ethosis collateral auctions. The two protocols cover different ground. Morpho handles deep, liquid collateral at variable rates; Ethosis handles the long tail on fixed, negotiated terms. Ethosis complements Morpho rather than competing with it. See [Idle capital](/protocol/idle-capital.md). ## Chainlink **What it does for Ethosis:** prices, market status, sequencer status, and potentially the eligibility policy engine. Data Feeds and Data Streams supply 24/5 equity prices with the ERC-8056 multiplier already applied. The Sequencer Uptime Feed governs the grace period after an outage. Chainlink ACE and CCID are candidates to become an adapter for the access registry once they are generally available on chain 4663. See [Oracles and market sessions](/risk/oracles.md). ## Paxos and USDG **What it does for Ethosis:** the settlement currency. USDG is native to Robinhood Chain and regulated under MiCA. Joint marketing with Paxos forms part of the go-to-market plan. See [Settlement asset: USDG](/assets/usdg.md). ## Uniswap and 1inch **What it does for Ethosis:** liquidity for liquidations, and price discovery. Uniswap v2, v3 and v4, together with 1inch, are live on the chain. The DEX depth behind each Stock Token feeds into its tier and its exposure cap, and DEX arbitrageurs are expected to be the most active bidders in collateral auctions. ## Account abstraction **What it does for Ethosis:** onboarding without gas, and batched transactions. The chain supports ERC-4337 entry points and EIP-7702. The front-end relies on Alchemy Account Kit for embedded accounts and sponsored gas, with ZeroDev as a fallback. A lender signs offers without spending gas; a borrower combines approve and borrow into a single user operation. Smart accounts sign through EIP-1271. ## Robinhood Wallet **What it does for Ethosis:** the main wallet for borrowers. The front-end deep-links into Robinhood Wallet, and a listing in the wallet's dApp directory is a distribution goal. ## Blockscout **What it does for Ethosis:** transaction-level transparency. Each event shown in the loan explorer links to its transaction on Blockscout. ## TRM Labs **What it does for Ethosis:** sanctions and AML screening. TRM runs at the sequencer level across the chain. Separately, the KYC provider that issues Ethosis eligibility attestations screens at issuance and at each renewal. The result is two independent screening layers. ## Indexing The loan explorer, the dashboards and the keeper bots all read from an indexer over chain 4663, either self-hosted Ponder (TypeScript) or Envio HyperIndex. See [Off-chain services](/architecture/off-chain-services.md). ## The wider Arbitrum ecosystem Because Robinhood Chain is an Arbitrum Orbit chain, Ethosis intends to apply for Arbitrum Foundation audit subsidies and to take 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.ethosis.org/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.
