I'm Ridwan — a full-stack engineer and prolific hackathon builder. From smart contracts to AI agents to the frontends that ship them, I've taken 40+ projects from idea to live deployment across more than fifteen ecosystems — winning a few along the way.
Projects that placed at hackathons — judged against the field and came out on top.
Pre-execution safety firewall for autonomous DeFi agents.
Runs eleven pre-execution checks on an agent's proposed swap, blocks unsafe trades, auto-remediates, and returns an EIP-712 signed, on-chain-verifiable plan that the PreflightGuard contract enforces. Shipped as an npm skill with 21 passing tests.
1st place · OKX Build X — Skill Arena
Composable pay-per-tick signal marketplace for agents.
A marketplace for paid agent intelligence where every call settles via x402 (EIP-3009 on USDT0) and composite signals cascade payments upstream to source authors, bound by an on-chain EIP-712 CascadeReceipt. Reference consumer Atlas V2 fires five real on-chain txns per tick.
2nd place · OKX Build X — X Layer Arena
Real-time autonomous transaction firewall for BNB Chain.
Intercepts Web3 transactions in real time and runs six pluggable analyzers to compute a weighted ShieldScore that blocks honeypots, rug pulls, and malicious contracts before execution. Delivered as a Chrome extension, RPC proxy, Telegram bot, REST API, and SDK; forensic reports stored on BNB Greenfield.
3rd place · Good Vibes Only Hackathon
Reusable private ZK-KYC layer for HashKey Chain.
Turns HashKey's existing KYC infrastructure into Semaphore zero-knowledge credentials any dApp can verify with a single Solidity require line — verify once, then privately prove KYC, accreditation, or jurisdiction without revealing identity on-chain. Ships an npm SDK, a Policy Composer, and 74 passing tests.
3rd place · HashKey Chain Horizon — ZKID
Offline multimodal maintenance copilot for technicians.
Lets industrial technicians search by photo of a broken part, error code, voice note, or manual snippet and returns evidence-backed fixes. Built on Actian VectorAI DB with named vectors, filtered search, and hybrid RRF fusion; runs 100% offline and CPU-only.

A few flagship products — all live, all on-chain.
Programmable conditional transfers on Sui.
On-chain inheritance with gasless zkLogin onboarding (sign in with Google — no wallet, no gas), Seal threshold-encrypted last-wishes letters stored on Walrus, and sponsored heir claims. Proven end-to-end on Sui testnet.
Sui Overflow 2026
The risk OS for Sui — crash & depeg insurance.
On-chain crash/depeg insurance built on DeepBook Predict. An SRX fear index from DeepBook's options surface, trustless sub-400ms oracle settlement, and an autonomous AI underwriter that prices and supplies cover on-chain while logging verifiable decisions to Walrus.
Sui Overflow 2026
A public on-chain index of autonomous AI yield agents.
The 'S&P 500 of AI yield agents' on Mantle — ERC-8004 agent identity and reputation, a reputation-weighted ERC-20 index token, EIP-712 signed receipts, and live AI agents publishing verifiable on-chain decisions. 130+ tests.
Mantle Turing Test 2026
Trustless AI arbitration for on-chain escrow.
A reusable AI-jury primitive on Somnia's agentic L1: convenes a panel of validator LLM agents that return byte-identical majority verdicts, with stake-backed appeals, graded split settlements, and an on-chain precedent registry. Multiple live disputes settled on Shannon.
Somnia Agora
Verifiable proofs of multi-model AI consensus.
Heterogeneous AI agents deliberate over a Gensyn encrypted P2P mesh, sign votes with ed25519, and anchor settlements on Gensyn L2. Each verdict mints a transferable, ENS-addressable receipt; transcripts persist to 0G Storage. 100+ settlements recorded.
ETHGlobal Open Agents 2026
Autonomous reputation watchdog for ERC-8004 agents.
Continuously discovers, analyzes, and scores every ERC-8004 agent on Base with no humans in the loop, returning a trust score backed by on-chain proof, IPFS-pinned evidence, and staked ETH. Has scored 3,769+ agents and unmasked 84 sybil networks in production.
Whether it's a protocol, an agent, or a product that needs to go from zero to live — I move fast and ship real things.
