What crypto and Solana are
Crypto in plain words: a shared public record of who owns what, and why memecoins live on Solana.
Crypto is digital money that no bank runs. Instead of one company keeping the record of who owns what, thousands of computers around the world keep the same copy of that record and check every change to it. That shared record is called a blockchain.
Think of it as a giant public notebook. Every page lists payments: this address sent that address 2 coins. Once a page is added, nobody can tear it out or rewrite it. Anyone can read the whole notebook, at any time, for free.
Why people care
- Nobody can reverse a payment once it is on the chain, and no bank can freeze your SOL. That is freedom, and it is also danger: a mistake or a scam cannot be undone.
- It runs all day, every day. No bank holidays, no closing time, no permission needed.
- Anyone can create a new coin in minutes. That is how memecoins are born, and why there are so many of them.
Coins and tokens
Each blockchain has its own main coin. Bitcoin's is BTC. Ethereum's is ETH. Solana's is SOL. On top of a chain, anyone can create extra tokens: a dollar-pegged token like USDC (a stablecoin), or a joke coin with a dog on it. Most memecoins in this guide are tokens on Solana. A few famous ones started on other chains: Dogecoin has its own, and Shiba Inu and Pepe began on Ethereum. The next track shows how to tell the real coin from a copy with the same name.
What Solana is
Solana is a blockchain that went live in 2020 and was built for speed and low cost. A payment usually confirms in about a second, and the basic network fee is a tiny fraction of a cent. That is why most memecoin trading happens there. When you might buy and sell ten times in a day, speed and fees matter a lot.
The computers that keep Solana running are called validators. They check each transaction, add it to the chain and earn fees for the work. Nobody owns the network as a whole.
What SOL is for
SOL does three jobs for you. You pay network fees in SOL. You buy memecoins with SOL. And you often measure your results in SOL, because most memecoins trade against it. Even if you only want to hold a memecoin, you need a little SOL to move it or sell it.
SOL splits into tiny pieces called lamports. One SOL is 1,000,000,000 lamports, the same way one dollar is 100 cents, just with more zeros. You will see lamports when people talk about fees.
One payment, start to finish
Ana wants to send 2 SOL to her friend Ben. In late October 2026 one SOL traded at about $99, so this is roughly $198.
- Step 1: Ana's wallet app builds the payment: 2 SOL from Ana's address to Ben's address.
- Step 2: She approves it. The app signs it with her private key, which proves the payment really comes from her.
- Step 3: Validators check that Ana's address holds at least 2 SOL plus the fee, then add the payment to the chain.
- Step 4: About a second later Ben's wallet shows 2 more SOL. Ana paid a network fee of 0.000005 SOL, which is 5,000 lamports, or about one twentieth of a cent.
- Step 5: Anyone can now look this payment up on a block explorer such as Solscan. It stays there forever.

This guide is for learning. It is not financial advice. Most memecoins go to zero and most people who trade them lose money. Only ever trade what you can afford to lose.
