Progress During Hackathon
Built end-to-end during the hackathon and deployed live to Robinhood Chain Testnet (chain ID 46630):
Five Solidity contracts shipped and verified on Blockscout: TokenConfigRegistry, ShortStackOracle, SwapAdapter, LendingPool (core: shares, kinked interest model, shorts, liquidation, pausability), and a read-only Lens for aggregated reads.
Full security posture: OpenZeppelin AccessControl/Pausable/ReentrancyGuard/SafeERC20, strict CEI pattern, custom errors, full NatSpec, role separation (owner/admin/guardian), and a staleness-protected oracle.
Test suite with unit, integration, fuzz/property, and solvency-invariant tests reaching ≥85% line coverage.
Next.js frontend with /lend, /short, /positions, /portfolio, /admin, and /pitch pages — wagmi v2/viem reads batched through L2 Multicall3, a network guard, health-factor warnings, and explorer-linked transaction toasts.
Node 20 + TypeScript liquidation bot with a 10s poll loop, retry/backoff, in-flight dedupe, restart reconciliation, and graceful shutdown.
Deploy + seed scripts that configure tokens, oracle prices, inventory, risk parameters, and the interest model against the real first-party token addresses on chain 46630.
Fundraising Status
Not raised. ShortStack is an independent hackathon project built for the Robinhood Chain track at Arbitrum Open House London. It is currently deployed on testnet only, is unaudited, and is pre-revenue with no external funding or token.
