Nine modules, 77 lessons. Modules are being translated from Lithuanian one at a time — where a module is not in English yet, it says so.
People who already hold crypto and want to understand the mechanics behind lending, liquidity provision and hedging — before committing capital, not after. Every lesson explains how a strategy can fail, not just how it works.
Educational material published from the EU. Not investment advice; no price predictions and no trading recommendations.
Yes, entirely. Every lesson and all three difficulty levels are free. There is no subscription and no hidden fee.

Solana: Kamino, Orca, Meteora, Jupiter. Ethereum: Aave, Uniswap V3 and V4. Options: Deribit. Each with step-by-step walkthroughs.
No. This is educational material published from the EU. It contains no price predictions and no trading recommendations — you make your own decisions.
The full course exists in Lithuanian and is being translated one module at a time, starting with the topics people search for most. Every lesson is fact-checked again during translation, so English lessons are not just a copy — several errors were found and fixed in the original this way.
Through affiliate links — when someone signs up to a platform through our link, we receive a small commission at no cost to you. That is the only revenue source, and no recommendation is ever made because of it.

Something practice teaches: when you paid nothing to learn, it is easy to postpone learning indefinitely. If these lessons actually gave you something — saved you a mistake, or explained what nobody else did — you can pay whatever you think they were worth.
This is not a price, a subscription, or a fee for access. The amount is yours to choose, and paying nothing is entirely fine.

Send SOL or SPL tokens (e.g. USDC) only on the Solana network. Sending from an exchange over a different network loses the funds permanently — nobody can recover them.
Nothing extra, and that is deliberate. Every lesson, all three difficulty levels and every calculator stay free and sign-up-free, with or without a donation. There is no gated section, no share of profits, no future token and no claim on anything.
A donation becomes my own money. I use it to keep the site running and to fund a public demonstration position on a lending protocol — real money, so the lessons have something to show instead of only theory. I publish the results, losses included, publicly and free for everyone. It is my position and my risk, not a pooled fund.
