# What Farlight connects to on Robinhood Chain

The protocols, oracles, wallets and services already running on Robinhood Chain that Farlight relies on, and the part each plays in the life of a loan.

Robinhood Chain already carries most of the infrastructure a lending protocol needs, so Farlight connects to it instead of building a second copy. Some of these integrations sit directly on the origination and liquidation path. Others surround it: wallets, screening, indexing, funding.

## Morpho Blue

**Role:** a home for idle lender capital, and a backstop for liquidation liquidity.

Morpho is the engine behind Robinhood Earn and holds about $80M to $90M of RWA deposits on the chain. Unmatched lender USDG is parked in a whitelisted Morpho USDG vault and withdrawn just in time when a loan originates. The liquidators and arbitrageurs who already work Morpho are natural bidders in Farlight collateral auctions.

The two protocols occupy different ground: Morpho serves deep, liquid collateral at variable rates, while Farlight serves the long tail on fixed, negotiated terms. One complements the other. See [Idle capital between fills](/protocol/idle-capital.md).

## Chainlink

**Role:** prices, market status, sequencer status, and possibly the eligibility policy engine.

Data Feeds and Data Streams deliver 24/5 equity prices with the ERC-8056 multiplier already applied. The Sequencer Uptime Feed drives the grace period after an outage. Chainlink ACE and CCID are candidates for an access registry adapter once they are generally available on chain 4663. See [Oracles, sessions and the price checks](/risk/oracles.md).

## Paxos and USDG

**Role:** the settlement currency.

Minted natively on Robinhood Chain and regulated under MiCA, USDG is the currency every loan is priced and settled in. Joint marketing with Paxos is part of the go-to-market plan. See [USDG as the settlement currency](/assets/usdg.md).

## Uniswap and 1inch

**Role:** liquidity for liquidations, and price discovery.

Uniswap v2, v3 and v4 are live on the chain alongside 1inch. The DEX depth behind each Stock Token informs its tier and its exposure cap, and DEX arbitrageurs are expected to be the most active bidders in collateral auctions.

## Account abstraction

**Role:** onboarding without gas, and batched transactions.

ERC-4337 entry points and EIP-7702 are both supported. The front-end uses Alchemy Account Kit for embedded accounts and sponsored gas, with ZeroDev as the fallback. Lenders sign offers without paying gas; borrowers fold approve and borrow into one user operation. Smart accounts sign through EIP-1271.

## Robinhood Wallet

**Role:** the primary wallet for borrowers.

The front-end deep-links into Robinhood Wallet. A listing in the wallet's dApp directory is a distribution target.

## Blockscout

**Role:** transaction-level transparency.

Every entry in a loan's flight log, the event history shown in the Observatory, links to its transaction on Blockscout.

## TRM Labs

**Role:** sanctions and AML screening.

TRM screens at the sequencer level for the whole chain. Independently, the KYC provider that issues Farlight eligibility attestations screens at issuance and at every renewal. Two separate layers cover the same ground.

## Indexing

The Observatory, the dashboards and the keeper bots all read from an indexer over chain 4663, either self-hosted Ponder (TypeScript) or Envio HyperIndex. See [The off-chain layer](/architecture/off-chain-services.md).

## The Arbitrum ecosystem

Robinhood Chain is an Arbitrum Orbit chain, so Farlight intends to apply for Arbitrum Foundation audit subsidies, to take part in the Arbitrum Open House 2026 buildathon track, and to join Chainlink BUILD.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.usefarlight.com/robinhood-chain/ecosystem.md?ask=<question>&goal=<endgoal>
```

`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.
