RBD Shield is a trust and accountability protocol for autonomous AI agents on Arbitrum — built for a world where agents execute trades, manage liquidity, and control on-chain capital with no human in the loop.
The problem is real: AI agents in DeFi can fail, mis-execute, or cause financial harm with zero recourse for users. Off-chain reputation scores don't help when money is lost.
RBD Shield solves this by letting agents register on-chain, stake collateral into vaults, and back their own service-level agreements with real capital. When pre-agreed failure conditions trigger, affected users receive automatic parametric payouts — no claims process, no arbitration.
The risk-scoring engine runs in a Stylus (Rust) contract, delivering on-chain actuarial math at a fraction of EVM gas costs. The frontend marketplace lets users browse registered agents, view their bonded collateral, and subscribe to coverage.
This is not another agent bot — it's the financial primitive the entire agent economy is missing: accountability backed by skin in the game.
Deployed on Arbitrum Sepolia. Stack: Solidity + Foundry, Stylus (Rust), React/Vite, Wagmi, Alchemy.<p>Built the entire protocol from scratch during the hackathon:</p><ul><li><p>Designed and deployed the core smart contracts (agent registry, collateral vaults, SLA enforcement, parametric payout logic) in Solidity + Foundry on Arbitrum Sepolia</p></li><li><p>Built the Stylus (Rust) risk-scoring engine for on-chain agent reliability evaluation</p></li><li><p>Developed the full React/Vite/TypeScript frontend marketplace connected to live on-chain data</p></li><li><p>Integrated Wagmi + Alchemy for wallet connection and RPC</p></li><li><p>Shipped a live working dApp at <a href="http://rbd-shield.onrender.com">rbd-shield.onrender.com</a></p></li><li><p>Wrote full test coverage with Forge and documented the protocol</p></li></ul><p>Zero pre-existing codebase — concept, contracts, risk engine, and frontend all built within the hackathon window.</p>
<p>RBD Shield is currently bootstrapped — fully self-funded and built solo during the hackathon with no external investment. No rounds have been raised to date.</p><p>The project is at MVP stage and open to grants, ecosystem funding, or strategic partnerships — particularly from within the Arbitrum ecosystem. The Arbitrum buildathon is the first step toward validating the concept publicly and exploring growth opportunities.</p>
