Before we build anything, let's get comfortable with the handful of words you'll see again and again. I'll use everyday comparisons instead of jargon, and every term gets its own little box so you can come back and find it fast.
You don't need to become a crypto expert to do this: you need about ten words. Let's go through them one at a time, slowly, with something familiar to compare each one to.
Imagine a notebook that millions of computers around the world all keep an identical copy of. Every time someone makes a transaction (sends money, creates a coin, trades one coin for another), a new line gets written into that notebook, on every copy, at the same time. Once written, a line can never be changed or deleted. That shared, tamper-proof notebook is what people mean by "the blockchain." It's the reason you can trust that a coin's history is real without having to trust any single company or person.
A crypto "wallet" is just an app (usually a free browser extension or phone app) that holds your coins and lets you approve transactions. Unlike a bank account, there's no bank in the middle: you alone control it, using a password-like list of words called a "recovery phrase." That's powerful (nobody can freeze it) and risky (if you lose that phrase, or someone else gets it, there's no customer support line to call). Write your recovery phrase down on paper, keep it somewhere safe and offline, and never type it into a website.
Every blockchain has its own main currency used to pay small processing fees: think of it like the local currency you need on hand for tolls. On Solana, that currency is called SOL. On Gate Layer, it's called GT. When you create a new memecoin, you're creating a brand-new, separate coin: but you still need a small amount of the blockchain's main currency in your wallet to pay the "toll" for creating and trading it.
You do not need to write any code to create a memecoin. Websites called "launchpads" (Pump.fun, LetsBONK.fun, and Gate Fun are the three we'll compare in Lesson 2) let you fill out a simple form (name, symbol, picture, description), connect your wallet, click a button, and your coin exists. This is the single biggest thing that makes memecoins different from traditional investments: creating one is closer to publishing a social media post than starting a company.
Once your coin is created, its price isn't set by you: it's set automatically by a simple, built-in rule called a bonding curve. Picture a vending machine that raises its own price a tiny bit every time someone buys, and lowers it a tiny bit every time someone sells. Nobody is in control of the price by hand: it just follows the rule, based purely on how many people are buying versus selling. If enough real buying happens, the coin crosses a size threshold and "graduates": meaning it moves off that starter vending-machine system and onto a normal trading marketplace.
Three more words you'll see constantly:
When you create a coin, most launchpads let you (the "creator") earn a small slice, often under 1%, of the value of every trade that happens on your coin, automatically, for as long as it keeps trading. This is the entire legitimate monetization model this guide is built around: you don't sell your own coins for a profit, you earn a small ongoing fee from other people choosing, on their own, to trade a coin you made.
"Wash trading" means trading with yourself: buying and selling between wallets you control, to make a coin look busier or more popular than it really is. It's illegal market manipulation, not a gray area, and it's the opposite of everything this guide teaches. We'll come back to this in Lesson 6, but it's worth planting early: real activity from real strangers is the only kind that counts, and the only kind that's legal to try to earn from.
