I've bought into more presales than I'd care to admit, some that turned into 40x wins and a few that turned into expensive lessons. The mechanics are the same every time. What trips people up isn't the concept. It's the small stuff. The wrong wallet, the fake link, the gas fee they forgot about. So here's the whole thing, start to finish, the way I'd walk a friend through it.
First, a quick reality check. A presale means you're buying a token before it lists on any exchange, usually at a lower price than the eventual launch. That's the upside. The downside is you're early, which means more risk. If you're fuzzy on the basics, read what a presale is before you put money anywhere.
Let's get into it.
What you need before you start
Three things. A self-custody wallet, some crypto to spend, and the official presale link. That's it. No exchange account required for the actual buy, though you'll probably use one to get your starting funds.
I'll use the Blazpay presale as the running example throughout because it's live right now, it's audited by QuillAudits, VC-backed, and it's raised over $3 million, so it's a clean, real-world case to point at. The steps are universal though. Swap in whatever presale you're actually buying.
The steps, in order
Here's the whole sequence. Do them in this order and you won't get lost.
- Set up a self-custody wallet. Install MetaMask (or Trust Wallet, Rabby, Coinbase Wallet) as a browser extension or phone app. Write your 12-word seed phrase on paper and store it offline. Never type it into a website, ever.
- Fund the wallet. Buy ETH, USDT, or BNB on an exchange, then withdraw it to your wallet's public address. Send a small test amount first, confirm it arrives, then send the rest. Keep a little extra for gas fees.
- Go to the official presale site and connect your wallet. Type the URL yourself or use a link from the project's verified channels. Click 'Connect Wallet' and approve the connection in your wallet popup.
- Verify the contract address. Match the presale contract shown on the page against the address in the project's official docs or pinned announcement. If they don't match, stop.
- Buy your allocation. Enter how much you want to spend, approve the token if you're paying in a stablecoin, then confirm the transaction. Wait for it to finish and check the site shows your allocation.
- Claim or vest at TGE. When the token generation event happens, return to the project's claim page, connect the same wallet, and claim your tokens. If they vest, come back for each release.
Now let me flesh out the parts that actually matter.
Setting up the wallet
MetaMask is the default for a reason. Most presales run on Ethereum or BNB Chain, and MetaMask handles both. Download it only from the official site or your phone's app store. Fakes exist, and they're good fakes. I've watched people install a lookalike extension with a five-star rating and 200 fake reviews, then wonder why their funds vanished an hour later.
Why self-custody and not just an exchange? Because presales run on-chain. You connect your wallet directly to the sale contract, and an exchange account can't do that. Your Coinbase or Binance balance sits behind their walls. A self-custody wallet is yours to plug into any dApp, which is exactly what a presale is.
The one rule I'd tattoo on people: your seed phrase is the wallet. Anyone who has it owns your money. Write it down. Store it somewhere physical. A presale site will never ask for it, and if one does, you've found a scam.
Funding it
You'll buy your ETH, USDT, or BNB on a centralized exchange, then withdraw to your wallet. Copy your public address carefully. It's a long string, and clipboard-hijacking malware is a real thing, so paste it and then eyeball the first and last four characters.
Send a tiny test amount first. A few dollars. Confirm it lands. Then send the rest. This one habit has saved me from disaster more than once.
And keep gas in the tank. On Ethereum a transaction might cost you a few dollars in ETH, sometimes more when the network's busy. If you send over exactly enough for the token and nothing for gas, you'll be stuck.
Connecting and buying
Head to the presale page. On the Blazpay presale page you'd connect your wallet and choose your amount, and nearly every other sale works the same way. You click connect, a popup appears, you approve.
Here's where people lose money, so slow down. Before you sign anything, confirm you're on the real site and the contract address matches the official one. Phishing clones copy the design pixel-for-pixel and just swap the wallet you're paying into. Cross-check the address every single time. It's worth learning how to check it isn't a scam before you commit real funds.
If you're paying with a stablecoin like USDT, you'll do two transactions: one to approve the token, one to buy. That's normal. Paying in the native coin (ETH or BNB) is usually a single transaction.
Enter your amount. Start smaller than you think you should on the first go. Confirm in your wallet. Wait for the green checkmark. The site should now show your allocation.
Before you decide how much to put in, it's smart to work out your potential ROI at a few different launch prices. Presales are a bet, and a bet you've sized is a lot calmer than one you haven't.
Claiming your tokens
This is the part beginners forget about. Your tokens don't show up in your wallet the moment you buy. Presale tokens are almost always distributed at the TGE, the token generation event, which is when the token officially launches.
When TGE hits, the project opens a claim page. You connect the same wallet you bought with, click claim, and the tokens land. Some projects vest instead, meaning you get a slice at launch and the rest drips out over weeks or months. If that's the case, set a reminder, because you'll need to come back for each unlock. I keep a note with the dates. Miss one and your tokens just sit there unclaimed, which isn't the end of the world, but it's annoying.
One thing worth saying: only use the official claim link. Scammers love TGE day. They spin up fake claim sites the second a launch is announced, hoping you'll connect your wallet and sign a malicious approval. Same discipline as before. Verify, then click.
My take
Buying a presale isn't hard. It's a checklist. Wallet, funds, connect, verify, buy, claim. The failures I've seen almost never come from the buying itself. They come from skipping the verify step, or chasing a link from a Telegram stranger, or forgetting to claim at TGE and missing a vesting window.
Go slow the first time. Use small amounts until the muscle memory kicks in. And treat every link with suspicion until you've matched that contract address yourself. Do that, and the rest is genuinely just clicking buttons.
