Much of the infrastructure a lending market needs already existed on Robinhood Chain when Spatial launched. The protocol connects to it instead of building it again. Below, each integration is sorted by the point where it meets a loan: along the route from origination to liquidation, at the user's side, and in the background. ## Along the loan's route ### Chainlink for prices and market status Data Feeds and Data Streams deliver equity prices 24/5 with the multiplier already applied. The Sequencer Uptime Feed triggers the grace period after an outage. Once ACE and CCID are generally available on chain 4663, they could sit behind the permission registry. The [pricing and sessions](/risk-and-safeguards/pricing.md) page has more. ### Paxos for the loan currency USDG is issued natively on the chain and falls under MiCA. All loans are priced, funded and repaid in it, and co-marketing with Paxos is part of the go-to-market plan. See [USDG as the loan currency](/what-can-be-pledged/usdg.md). ### Morpho Blue for idle capital and auction bidders Morpho runs Robinhood Earn and holds about $80M to $90M in RWA deposits on this chain. Lender USDG that has not been matched yet waits in a whitelisted Morpho USDG vault and is withdrawn as soon as a loan is created. Arbitrageurs and liquidators who already work on Morpho are obvious bidders in Spatial's liquidation auctions. The two protocols do not compete. Morpho offers variable-rate loans against deep, liquid collateral, while Spatial offers fixed, negotiated rates against long-tail collateral. More in [Idle capital between fills](/how-loans-work/parked-capital.md). ### Uniswap and 1inch for market depth The chain hosts Uniswap v2, v3 and v4 along with 1inch. How deep the DEX market is for a Stock Token feeds into its tier and its exposure cap, and arbitrageurs working those pools should be the most active bidders when liquidation auctions run. ## At the user's side ### Smart accounts Both EIP-7702 and ERC-4337 entry points work on the chain, and Alchemy Gas Manager and ZeroDev supply the infrastructure. Spatial's platform handles signing through Privy, covering sign-in, embedded wallets and gas-free EIP-712 signatures, so lenders can post offers at no gas cost. A single user operation can bundle approve and borrow, and smart accounts produce signatures via EIP-1271. See [Platform architecture](/inside-the-protocol/platform.md). ### Robinhood Wallet This is the main wallet for borrowers. The platform deep-links to it, and getting listed in its dApp directory is among the distribution aims. ### TRM Labs TRM provides sanctions and AML screening in two independent layers. It screens the entire chain at the sequencer, and the KYC provider that backs Spatial's attestations screens users when a credential is issued and again each time it is renewed. ## In the background ### Blockscout Each entry in a flight log, the event history shown per loan in the Explorer, links through to its transaction on Blockscout. See [Using the Explorer](/step-by-step-guides/explorer.md). ### Indexing for the Explorer and keepers Loans, slices and events in the Explorer come from the platform's Supabase registry. For dashboards and keeper bots that read chain 4663 directly, two indexers have been evaluated: Ponder (self-hosted, TypeScript) and Envio HyperIndex. See [Off-chain services](/inside-the-protocol/services.md). ### Arbitrum Because Robinhood Chain is an Arbitrum Orbit chain, Spatial can apply for Arbitrum Foundation audit subsidies, the Arbitrum Open House 2026 buildathon track and Chainlink BUILD, and it plans to go after all three. --- # 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/neighbours.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.
