Ward

Ward is a credit line backed by tokenized stocks on Robinhood Chain, with an anti-liquidation autopilot. Borrow USDG against assets like TSLA, and an on-chain keeper repays from your safety buffer before a crash can liquidate you. Risk is priced by a volatility-aware engine written in Rust with Arbitrum Stylus.

Description

Borrowing against volatile tokenized stocks is risky: a 16% dip can liquidate a healthy loan and seize your collateral. Ward fixes this.

You deposit a stock token, borrow USDG, fund a small USDG buffer and set a trigger/target. A keeper monitors your health factor every block and, before liquidation, repays just enough from your buffer to restore safety, keeping your collateral and your upside. The threshold adapts to volatility, computed on-chain in Stylus.

Progress During Hackathon

Built entirely during the Buildathon: the Solidity protocol (LendingCore, WardVault, interest + risk models, liquidation backstop), a dynamic risk engine in Rust/Stylus (realized volatility → adaptive liquidation threshold), the anti-liquidation keeper (de-risking-only, security invariant), and a Next.js app. All deployed and live on Robinhood Chain testnet, with a full end-to-end demo: deposit, borrow, arm Ward, crash the price, watch it protect, on-chain.

Fundraising Status

Not currently fundraising — built for the Arbitrum Open House London Buildathon. Open to grants and pre-seed conversations to bring Ward to mainnet.
