A case study in treating scientific peer review as a coordination game: authors stake ETH, an AI agent screens for plagiarism, Chainlink VRF picks reviewers, and human verdicts settle on-chain — with research artifacts pinned to IPFS.

• Getter-less contract, event-sourced reads — BioVerifyV3 emits events instead of exposing view getters; Alchemy Notify delivers logs to an HMAC-SHA256-verified webhook that projects into Neon Postgres with optimistic concurrency — the frontend reads from the projection, not the chain.
• Dual-agent pipeline — a Submission Agent fetches the IPFS manifest and runs a neural search via Exa AI for plagiarism screening; a Review Agent manages multi-day human-in-the-loop peer review, with LangGraph checkpointers and Inngest durable execution so workflows survive serverless cold starts.
• Trust-minimized reviewer selection — after screening passes, Chainlink VRF provides cryptographically verifiable randomness to pick peer reviewers from the staked pool — no operator or contract owner can influence who reviews a submission.

A proof-of-concept for running prediction markets where settlement is decentralized and tamper-resistant, staying outside any operator's hands: Chainlink Price Feeds set the price at deadline, Automation triggers resolution, and VRF randomizes ERC-1155 rewards.

• Automation-driven resolution — Chainlink Automation calls performUpkeep so eligible rounds move without a human operator clicking resolve.
• Verifiable inputs — Chainlink Price Feeds for settlement prices and Chainlink VRF v2.5 for unpredictable ERC-1155 reward ids.

An experiment in ERC-1155 crafting rules: the ledger (FToken) handles balances while the rules contract (Forge) encodes recipes, cooldowns, and atomic burn-then-mint — with 100% Foundry coverage.

• Atomic forging — Composite tokens (IDs 3–6) are created by burning their inputs and minting the result in a single transaction (burnBatch + mint) — one wallet confirmation, no half-updated balances.
• Ownership-gated composition — Forge deploys FToken (ERC-1155) and becomes its immutable owner; all supply mutations are gated behind onlyOwner, cleanly separating crafting rules from the token ledger.
• Foundry rigor — 37 tests, 100% coverage on Forge.sol, FToken.sol, and deploy scripts; contracts verified on Sepolia.

A learning build for real-time full-stack flows: live multi-user bidding over Supabase Realtime, automated auction closure via CRON + Edge Functions, and Stripe settlement with RLS-safe webhook handling.

• Asynchronous Settlement — secure Stripe webhook ingestion, using elevated Supabase Service Roles to safely bypass Row Level Security (RLS) and update payment states asynchronously.
• Automated lifecycle + live sync — a Supabase CRON job triggers the close-auctions Edge Function on schedule; DB changes propagate to all connected clients via Supabase Realtime broadcasts.
• i18n + DDD — French, English, and German via Lingui; domain/ports/repositories/services with Jest coverage on core workflows.
