描述

Peridot brings lending, liquidity and long/short markets to Robinhood Stock Tokens, with cross-chain access and fiat onboarding in the same product. It is built for people who want to borrow against their Stock Tokens without selling them, earn returns by supplying capital, or take a (leveraged) position in either market direction.

Check it out here:

Our first market pair is NVDA Stock Token and USDG on Robinhood Chain mainnet. The lending markets, isolated-margin contracts and paired liquidity vault integrate the mainnet NVDA Stock Token, USDG and Uniswap v4 infrastructure. USDG connects the system as the stable side of the liquidity pair, the borrowing asset for long positions, and the underlying asset of the pUSDG margin collateral.

Cross-chain access is already working, including from Solana. Users can access Peridot with funds from Ethereum, Avalanche and Solana without manually switching to Robinhood Chain. Stock Token execution remains on Robinhood Chain, while the access layer connects capital from other ecosystems.

Fiat onboarding and virtual accounts are also operational. Users can fund Peridot through the integrated fiat on-ramp and their assigned virtual account details, including virtual IBAN functionality. This gives the product an entry point for people arriving with bank funds as well as those who already hold crypto.

Lending and long/short markets

Suppliers deposit NVDA or USDG into lending markets and receive pTokens representing their claims. Borrowers can access liquidity against eligible collateral, while suppliers earn interest from borrowing activity. These same two markets provide the credit used by Peridot’s isolated-margin system.

A long position borrows USDG to increase NVDA exposure. A short position borrows NVDA and sells it for USDG, creating exposure to a decline in the Stock Token’s price. Both directions use pUSDG as deposited margin, with positions held in separate custody accounts. The contracts are configured for up to 5× gross leverage, subject to conservative canary limits and the protocol’s risk checks.

A dedicated cloud keeper provides liquidation infrastructure but users can run liquidation as well. The stock-price guard rejects stale prices and also reduces functionality on the weekend.

Boosted lending liquidity

Peridot’s Boosted Markets connect lending liquidity to a paired Uniswap v4 strategy. A controlled portion of matched value from the NVDA and USDG lending markets can enter a full-range NVDA/USDG liquidity position.

Capital allocated to borrowers earns lending interest; capital allocated to Uniswap can earn trading fees. Both can contribute to suppliers’ returns without requiring each supplier to manage a separate LP position. Cash buffers and allocation limits determine how much capital enters the strategy. They do not guarantee a fixed yield or immediate withdrawal of every deposit.

Providing liquidity between a Stock Token and USDG introduces divergence risk. A configured share of collected Uniswap LP fees is routed into an in-kind strategy reserve, which can also receive direct funding.

This is a capped reserve-backed loss mitigation.

Product roadmap

The next market expansion is additional Robinhood Stock Token pairs. NVDA/USDG establishes the initial lending, liquidity and margin structure; further markets would extend those functions to more assets, with their own liquidity, oracle and risk configurations.

We also plan an opt-in accounting layer that lets users give up a chosen portion of their supply rewards in exchange for a lower effective borrowing rate. For someone who both supplies and borrows, this creates a practical choice: retain more of their rewards, or use part of that economic benefit to reduce borrowing costs. The feature is intended to make the relationship between what a user earns and what they pay more flexible, rather than treating the two sides of their account independently.

Longer term, we plan to bring Peridot to a mobile app, combining account funding, deposited assets, borrowing and position management in one interface. The existing cross-chain and fiat integrations provide the foundation for that experience.

A future credit card linked to borrowing against deposited Stock Tokens would extend the lending product into everyday spending. A user could retain their deposited Stock Tokens as collateral and spend borrowed funds through the card, rather than selling the tokens to fund a purchase. This would require a card-issuing integration, with spending capacity tied to available borrowing capacity and the underlying loan’s interest, repayment and collateral requirements.

本次黑客松进展

We entered the buildathon with Peridot’s lending and boosted-vault foundations. During the event, we extended them into isolated long/short markets for NVDA Stock Token and USDG on Robinhood Chain mainnet, then completed real lending, long-position and short-position round trips. The work connects the mainnet Stock Token and USDG markets to borrowing, leveraged trading and our paired Uniswap v4 strategy. On September 18, we deployed the isolated-margin stack through 66 user-signed transactions, with verification covering 31 runtime targets and 53 contract-wiring checks. On September 19, we completed a four-transaction update configuring both directions for up to 5× gross leverage, with 20% initial margin and 10% maintenance margin. Long positions borrow USDG against NVDA exposure; short positions borrow NVDA against USDG assets. Both use pUSDG as deposited margin. Lending was reactivated on September 29 following contract hardening and verification. On September 30, we completed a ten-transaction lending cycle covering NVDA supply, collateral activation, USDG borrowing, full repayment and redemption. We also completed a six-transaction long-position cycle that day, followed by a six-transaction short-position cycle on October 1. Both margin positions were opened, fully closed and their returned pUSDG shares withdrawn, with no remaining position debt or locked margin. The margin tests used 2× and 5x requested gross leverage within the initial $2 gross-assets and $1 debt limits per position. By September 20, the dedicated cloud liquidation keeper was funded and execution-enabled, using its own signer and a durable PostgreSQL transaction journal. We also strengthened mixed-decimal lending valuation and shared-loss accounting in the paired vault, installing both corrections on mainnet on September 26. The vault upgrade preserved its public interface, storage layout and existing account ledgers. The keeper is deployed as well. We published the dedicated PeridotV2-Robinhood repository with pinned compiler inputs, source hashes, deployment receipts, frontend interfaces and automated CI checks. The evidence includes reproduction of 26 archived artifacts and verification of 16 frontend ABIs. Test coverage is reported separately by scope: 92 baseline Solidity tests, eight lending-adapter regressions, 50 unique V2 vault tests, six lending mainnet-fork checks and three vault mainnet-fork checks. These cover price units, borrowing boundaries, liquidation quotes, shared-loss accounting and upgrade compatibility, including fuzz and invariant testing. The wider Peridot product also has working cross-chain access from Ethereum, Avalanche, Solana and more chains, together with fiat onboarding and virtual accounts, including virtual IBANs. These capabilities complement Robinhood Chain by bringing in outside capital with the best user experience we can offer. The buildathon’s completed mainnet workflows cover supplying, borrowing, repaying, redeeming, and opening and closing leveraged positions in both directions. The paired LP strategy and capped reserve-backed loss mitigation are deployed alongside them.

融资状态

Peridot has been bootstrapped through hackathon prizes and a grant from the Stellar Development Foundation (SDF), with no outside investment raised to date. We are currently raising $1 million. SDF has offered to match outside investment up to $500,000, conditional on securing the corresponding investment.
