DEmystiFI

DemystiFI is a browser extension that removes the biggest barrier to DeFi for newcomers: not understanding what anything means. Hover over any DeFi or crypto term on a page — Bridge, Swap, Gas, NFT, Perpetuals, Staking, and more — and it explains that term in plain language, using an analogy from your own career field (IT, marketing, finance, healthcare, education) or a beginner-friendly explanation if you're new to everything. The goal is simple: someone who's currently too intimidated to try DeFi should be able to actually understand what they're looking at, and be more willing to participate in trading or investing as a result. Every time you mark a concept as understood, that's recorded onchain via a minimal smart contract on Monad testnet — a public, tamper-proof record of what you've actually learned, not just a UI toggle. Building this taught me the full deploy pipeline for the first time: writing a Solidity contract, using a testnet faucet to fund a wallet with test MON, configuring a wallet to a custom EVM network (RPC URL, chain ID), and deploying with Hardhat to Monad testnet. I also wired in live, tailored explanations using Anthropic's API directly from the browser (a "bring your own key" pattern) for terms outside the pre-written set, alongside window.ethereum calls from a content script to submit real transactions. Going from "I don't understand crypto" to shipping something that runs on it was the whole point of the project turning into its own proof of concept.
