Most of what a lending market needs was on Robinhood Chain before Gimbal arrived. Rather than rebuild any of it, the protocol connects to it. Below, the integrations are grouped by where they touch a loan: on the path from origination to liquidation, around the user, and behind the scenes. ## On the loan path ### Chainlink: prices and status Equity prices arrive 24/5 through Data Feeds and Data Streams, multiplier included. The Sequencer Uptime Feed starts the post-outage grace period. ACE and CCID, once generally available on chain 4663, could back the role registry. Details on the [pricing and sessions](/risk/pricing.md) page. ### Paxos: the loan currency USDG is minted natively on the chain and regulated under MiCA. Every loan is priced, funded and repaid in it. Joint marketing with Paxos features in the go-to-market plan. More on [USDG, the loan currency](/collateral/usdg.md). ### Morpho Blue: parked capital and auction liquidity Morpho powers Robinhood Earn and carries RWA deposits of roughly $80M to $90M on Robinhood Chain. Lender USDG that has not yet been matched sits in a Morpho USDG vault on the whitelist and is pulled out the moment a loan is written. The arbitrageurs and liquidators already active on Morpho are natural bidders in a Gimbal collateral auction. The two are not rivals. Morpho lends against deep, liquid collateral at a variable rate; Gimbal lends against the long tail at fixed, negotiated rates. See [Capital parked between fills](/mechanics/parked-capital.md). ### Uniswap and 1inch: where depth comes from Versions 2, 3 and 4 of Uniswap run on the chain, as does 1inch. The DEX depth behind a Stock Token informs both the tier and the exposure cap, and arbitrageurs from those pools are expected to be the busiest bidders in collateral auctions. ## Around the user ### Account abstraction The chain supports ERC-4337 entry points and EIP-7702, with Alchemy Gas Manager and ZeroDev available as infrastructure. The platform signs through Privy: sign-in, embedded wallets and gasless EIP-712 signing, so lenders post offers without paying gas. Approve and borrow can be folded into one user operation, and smart accounts sign through EIP-1271. See [How the platform is built](/architecture/platform.md). ### Robinhood Wallet The primary borrower wallet. The platform deep-links into it, and a listing in its dApp directory is one of the distribution goals. ### TRM Labs Sanctions and AML screening at two layers that do not depend on each other: TRM screens at the sequencer for the whole chain, and the KYC provider behind Gimbal's attestations screens at issuance and again at every renewal. ## Behind the scenes ### Blockscout Every line of a flight log, the per-loan event history in the Explorer, links to the transaction on Blockscout. See [Reading the Explorer](/guides/explorer.md). ### Data for the Explorer and keepers The Explorer reads loans, slices and events from the platform's Supabase registry. Ponder, self-hosted in TypeScript, and Envio HyperIndex are the two indexers evaluated for reading chain 4663 directly for dashboards and keeper bots. See [Services off the chain](/architecture/services.md). ### Arbitrum As an Arbitrum Orbit chain, Robinhood Chain gives Gimbal access to Arbitrum Foundation audit subsidies, the buildathon track at Arbitrum Open House 2026, and Chainlink BUILD; the protocol intends to pursue all three. --- # 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.usegimbal.app/robinhood-chain/neighbours.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.
