Stock Oracle Guard — Buildathon Progress What we're building: A safety system for the Arbitrum Open House Singapore Buildathon. Stock tokens (like tokenized TSLA) trade 24/7, but their price feeds only update 5 days a week — so lending apps can get tricked by stale weekend prices. Our project fixes that. What's done: Smart contracts — built and tested (23 passing tests) the core safety logic: it checks if a price is trustworthy, knows when markets are closed (weekends/holidays), and blocks risky actions (like liquidations) when data is stale or paused. Live on testnet — fully deployed and working on Robinhood Chain's test network. Verified with real transactions, including a full end-to-end test: deposit collateral → borrow → simulate a price crash → liquidate. Worked exactly as designed. Tested against real mainnet data — ran our contracts against the actual live Chainlink price feed to confirm the logic holds up outside of test conditions. SDK (developer toolkit) — a TypeScript library so other developers can easily plug this safety layer into their own apps. Verified working against the live deployment. Keeper bot — an automated script that keeps the market holiday calendar up to date on-chain. Frontend & live demo — a teammate built a website on top of this (dashboard + interactive walkthrough) and it's deployed and publicly accessible. Fixed a few bugs along the way (wallet connection issues, network switching errors). Where things stand: Everything — contracts, SDK, keeper, and the live demo site — is deployed, tested, and working end-to-end. Repo is public and the site auto-updates when we push changes.
