What's New

You have heard of DeFi. Maybe you even use it. But between you and the people who live in it sits a wall of words nobody stops to explain: funding rates, impermanent loss, ve-tokenomics, real yield, FDV. Your First 90 Days in DeFi tears that wall down one checkpoint at a time, starting where DeFi actually starts: how any market works, from the NYSE to an AMM pool.

24 interactive checkpoints across four acts: The Market, The Protocols, The Deep Water, and Fluency. You will follow leverage to its liquidation, walk the x times y equals k curve, find out where every yield really comes from, and finish by reading a protocol you have never seen, cold, in twenty minutes. One question runs through the whole course: who is paying, and why? Answer it reflexively and you stop being a tourist.

About twenty minutes per checkpoint, Lynx and the 90 Days leaderboard included, and no code anywhere. The first three checkpoints need no account. If you are brand new, start with Your First 90 Days in Web3 first; this course picks up where it leaves off and goes deep.

Zealynx Insiders is the room we wish existed when we got into security. Not a course you finish, and not another chat channel, but a membership where devs, founders, auditors, and anyone between roles keep getting better alongside people on the same path. It is worth more the longer you stay.

Inside: Zealynx Live weekly sessions where the room works through real content together, a library of findings, prompts, and post-mortems, a member directory, ranks and a leaderboard, office hours with Carlos, and study groups you can run yourself. Founders also get direct advice, Krait runs on their contracts, and a founding discount on a full Zealynx audit. You also get a direct support line to the whole Zealynx stack: the Academy, Audit Grants, and Krait.

Founding pricing is $20 per month, locked for life, for anyone who joins before July 16. After that it moves to $50. Joining the waitlist is free, and there is no charge until we open. Reserve your seat and you are first in line.

New to Web3, or been around a while without ever building the foundation? Foundations is your on-ramp. Your First 90 Days in Web3 walks the whole space, what crypto and DeFi actually are, wallets, NFTs, scams, security, one connected idea at a time, until it stops being noise and becomes a map you can read.

24 interactive checkpoints across four acts, about twenty minutes each. You learn to judge things by what they do, not what they say, the same lens a professional auditor uses. Earn Lynx as you go and climb the new 90 Days leaderboard. The first three checkpoints need no account, and an audio companion is coming soon.

Finish a Build module, review a Shadow Arena audit, ship an AI Auditor, wrap an eMBA module, or unlock a new rank. When you share it to X for your +10 Lynx, the post now lands publicly on the Academy Feed. Click any entry to read the original tweet, see the card, or open the builder's profile.

Two-column layout on desktop with a live sidebar (top builders this week, trending protocols and audits), a sticky filter strip to slice the feed by kind, and verification gating so every entry on the page is a real tweet from a real builder. No engagement gaming, no follower-of-followers noise. Only shipped work.

Find it from the Header (Feed tab), or directly at /feed. At launch you will see a sample timeline showing what each card kind looks like; those disappear automatically once real posts start landing.

The Build track gains its fourth protocol: Liquity V1, the cleanest CDP/stablecoin design in DeFi. Open a Trove, borrow LUSD against ETH, absorb liquidations into the Stability Pool, enforce the peg through redemptions — every function, every invariant, modernized to Solidity 0.8.x. 15 sections across 3 parts.

Paired with it: four new Shadow Arena audits on real Liquity forks — Gravita (multi-collateral), Lybra V2 (liquid-staked collateral), Tapioca (cross-chain, a 4-week boss fight), and Raft (a true production fork, including the precision bug behind a $6.7M exploit). Build the protocol, then break its forks.

Hit a milestone — a finished Build module, a reviewed Shadow Arena audit, a completed eMBA module, or the AI Auditor Builder — and a Share-to-X card now appears on the completion screen and on your dashboard. Post it, and +10 Lynx land in your balance.

No farming: the bonus is gated on real completion and capped at one claim per milestone per account, enforced server-side.
