This course follows one trade from the first search to the final review. The token is Pebble (PBL). It is illustrative and its numbers are invented, but every figure is computed from one consistent market, so what you learn in one lesson carries into the next. The trade starts where most trades start: with a name in a search box.
A meme coin is a token
A meme coin is a digital token whose attention often comes from an internet community, joke, or narrative. Its price can move because buyers and sellers change their minds quickly. A memorable name does not create cash flows, ownership rights, or a reliable floor under the price.
On Solana, a token is identified by its mint address, a long string that only one token can have. Names, symbols, and images are labels anyone can choose. Search for Pebble and you get three results, all called Pebble, all with the ticker PBL. Two of them even share the first and last four characters of the address, which is all most screens show.
A price needs a market
A displayed price is a recent observation or quote, not a promise that your whole order can trade there. A pool needs enough of the other asset on its far side for the amount you want to exchange. The larger your order relative to that, the further your result drifts from the displayed price. Lesson 04 measures exactly how far.
Trading is a sequence of decisions: choose a token, test whether it can be bought and sold, decide how much you can lose, define an exit, and review what happened. This course walks Pebble through each of those decisions in order.
A useful first rule
Treat every unfamiliar token as a question to investigate. Ask what you know about its identity, liquidity, holder concentration, token controls, and the reason you would exit. If a key fact is unknown, write down the uncertainty instead of replacing it with confidence.
That habit of writing things down is the thread of this course. Each lesson adds one entry to Pebble's file. By lesson 20 the file is the whole trade, and the review is only possible because the file exists.
Practice with paper SOL
PaperTrader gives you simulated SOL in a paper wallet. A paper buy changes only that simulated balance and the recorded position. You do not deposit SOL, sign a transaction, or own the token on-chain. Your practice results are a record of modeled decisions, not withdrawable funds.
Practice
Open one token in Discover. Record its full mint address, displayed price, liquidity, and one reason you would avoid trading it. Find the mint in the project's own channels and compare every character. Do not place a trade yet.
Added to Pebble's file
1 of 2019 entries still to come. The file is the journal you will grade in lesson 16.
