How Placerion works under the hood.

Setting up a wallet

Placerion is designed to work without requiring any technical knowledge.
For collectors who want to explore advanced features — such as minting stamps as NFTs or managing their own digital assets — this page explains the underlying technology in a clear and practical way. You’ll learn what a wallet is, how NFTs work, and how to stay in control of your collection at every step.

Option 1: Quick setup with Google or ApplE

Go to the official Phantom website: https://phantom.com/

Click Download and choose your device (iOS, Android, or browser extension for Chrome, Edge, or Firefox)

Open the app and click Continue with Google or Continue with Apple

You’ll get a recovery phrase (12 secret words). This is the “master key” to your wallet. Write it down and store it somewhere safe — never share it with anyone

That’s it! You can now start receiving and storing NFTs.

Option 2: Create a wallet manually

Install the Phantom Wallet app or browser extension

Click Create a new wallet

Phantom will generate your recovery phrase — carefully write it down and keep it offline (never in email or cloud storage)

Set a strong password for quick logins

Your wallet is ready — you’ll see your public wallet address (looks like a long string of letters and numbers). This is what you share to receive NFTs

Why Phantom?

Super easy for beginners.

Works perfectly with Solana (where Placerion NFTs live)

Mint your digital stamp as an NFT

Your Placerion digital stamp can be optionally minted as an NFT.

Minting turns your stamp into a blockchain-based digital collectible that you fully own and control in your own non-custodial wallet. This step is completely optional — your stamp remains valid on the Placerion platform even if you never mint it and minting is not required to use the Placerion platform.

New to the NFT world?

To understand NFTs, let’s start with the word itself: non-fungible token.

Fungible = interchangeable. Some things in life are all the same. For example, one $1 bill can always be swapped for another $1 bill — they’re identical in value. The same goes for a train ticket or a liter of milk. You don’t care which one you get, because they’re all equal.

Non-fungible = unique. Other things are one-of-a-kind. Think of a painting, a signed baseball, or your own passport. Even if someone made a copy, it wouldn’t be the same — the original has its own history and value.

How NFTs Work

Whenever an NFT is created, bought, sold, or transferred, it’s written into this notebook. Once it’s written down, it stays there forever. Anyone can open the notebook and check the full history.

For example: Imagine buying a piece of art. Normally you’d get a piece of paper that says it’s authentic. But papers can be lost, destroyed, or forged. With NFTs, the proof is built directly into the blockchain. You can see:

Who created it

Every person who has owned it

Every sale price since it was first made.

It’s like giving each item a digital passport that proves it’s the real thing.

Selling your NFTs

You can also sell or trade your NFTs on marketplaces like OpenSea, Magic Eden, or Blur. When someone buys your NFT, you receive cryptocurrency directly in your wallet, which you can later convert into regular money (EUR, CZK, USD) through an exchange such as Coinbase, Binance, or Kraken.

Security tips for beginners

Your NFTs are valuable digital collectibles, so keeping them safe is important. Here are a few simple rules:

Never share your recovery phrase

When you create a wallet, you’ll receive 12 secret words (your recovery phrase). This is the master key to everything you own. Keep it offline, write it down, and never send it by email or message.

Use only official apps and websites

Download wallets like Phantom only from their official website or app store. Access Placerion and mint stamps only through official Placerion pages, and scan Placerion QR codes exclusively at partner locations.

Beware of scams

If someone asks for your recovery phrase or wallet password, it’s a scam. Placerion will never ask you for these details.

Keep your device secure

Use a strong password on your phone or computer, and keep your software up to date.

By following these simple steps, your collection will stay safe and fully under your control.

Glossary

Crypto / Cryptocurrency - Digital money used online, like Bitcoin (BTC), Ethereum (ETH), or Solana (SOL). You can use it to buy NFTs or exchange it for traditional money (EUR, USD, CZK).

Blockchain - A blockchain is a shared digital record (like a permanent online notebook) where information (like who owns an NFT) is stored in linked blocks. Every action — such as creating, buying, or selling an NFT — is recorded forever and once added, it can’t be changed. This makes it safe and trustworthy., making it safe and trustworthy.

NFT - NFT (non-fungible token) is a unique digital collectible stored on a blockchain. NFTs can represent almost anything, but unlike a regular file or image, an NFT serves as a digital record of ownership. It can’t be copied, replaced, or faked.

Wallet - A wallet is a digital tool you need to store your NFTs and the cryptocurrency used to buy them. It works like an online keychain that proves what’s yours. Popular examples are MetaMask, Coinbase Wallet, and Phantom.

Solana - The blockchain where all Placerion NFTs live. Solana is fast, low-cost, and environmentally friendly, making it perfect for collectibles.

Gas Fee / Transaction Fee - A small fee paid when you buy, sell, or move an NFT on the blockchain. On Solana these fees are very low, usually just a fraction of a cent.
