Hi crypto fans 💸

As you all know, adding custom tokens to your wallet is a powerful way to expand your crypto portfolio. However, it requires a security-first mindset. While the process is straightforward, it is critical to exercise extreme caution: adding tokens with unverified addresses can expose you to sophisticated scams.

One of the most prevalent threats in the crypto space is address spoofing, where fraudsters create counterfeit tokens that look identical to legitimate ones. To keep your assets safe, you must always double-check the official contract address through trusted sources before hitting “Add,” as interacting with a fake address is a common trap that can lead to a total loss of funds.

Let’s begin!

Step 1. Open Your Wallet

If you aren’t yet a part of the Coin Wallet community, you can download the app any way you like — for example, from the App Store, Google Play, Galaxy Store, or the web version. After that, create a new wallet or export an existing one. Now you’re ready to go!

If you’re already with us, just open the app and follow the next steps below.

Step 2. Add a New Token From the List

That’s a very easy task. You have already opened the wallet and you’re looking at the screen where there is a list of cryptocurrencies. By default, three tokens are available: Bitcoin, Litecoin, and Monero. However, you can add more tokens by scrolling down the screen and tapping the “Add crypto” button.

Now you will be able to choose tokens from the list. For example, our new crypto, Kaspa (KAS).

Step 3. How to Add a New Token Outside the List

You also have one more option — to add a new token that is not on the Coin Wallet list, let’s say Pengu. For that, you need to go through the same steps, but tap the “Add custom token” button in the token menu.

To add a custom token, choose a blockchain from the list and enter a contract address. You can use the “Paste” option or scan a QR code. After that, tap “Continue,” and the token will appear in your wallet.

That’s all, you’re perfect ❤️

Now we have some important details for you.

What Is the Contract Address of a Custom Token?

In blockchain technology, a contract address is the unique digital identifier for a smart contract.

A smart contract is self-executing code recorded on a blockchain that automatically fulfills the terms of an agreement once the conditions are met.

While a standard wallet address (like the one you use to hold Bitcoin or Ethereum) is controlled by a person with a private key, a contract address is controlled by pre-written code. It acts as the “home” for an application on the blockchain, allowing users and other contracts to interact with it.

Many modern cryptocurrencies, such as Ethereum, Solana, and Cardano, actively use smart contracts to create decentralized applications (dApps), tokens (DeFi), and to automate transactions without intermediaries. In our case, the Pengu Penguins token is based on the Solana blockchain.

Although Bitcoin itself has basic scripting capabilities, networks like the Lightning Network further expand its possibilities.

Frequently Asked Questions

Where Can I Get a Reliable Contract Address?

The safest way to find a contract address is through official sources. Always start with the project’s official website, verified social media accounts, or trusted blockchain explorers. Avoid copying addresses from comments, ads, or random messages — this is one of the most common ways people get scammed. When in doubt, double-check the same address across multiple trusted sources before adding a token to your wallet.

What's the Difference Between a Token and a Cryptocurrency?

A cryptocurrency usually refers to a native coin of a blockchain, like Bitcoin or Solana. These coins are used to pay network fees and secure the blockchain itself.

A token, on the other hand, is created on top of an existing blockchain using smart contracts. Tokens can represent almost anything: utility, governance, access, or even digital collectibles. In short, all tokens are crypto assets, but not all crypto assets are native cryptocurrencies.

How to Add Crypto to Stake

Before staking, make sure the token you want to stake is already added to your wallet. Then, check whether the blockchain or project supports staking directly in the app or through an external validator or platform. Once staking is available, choose the amount, confirm the transaction, and sign it with your wallet. Your assets remain yours — they’re just temporarily locked to help secure the network and earn rewards.

How Do Crypto Tokens Work?

Crypto tokens are powered by smart contracts. These contracts define how many tokens exist, how they can be transferred, and what they can be used for. When you send or receive a token, you’re interacting with its smart contract on the blockchain. Everything happens automatically, without banks or intermediaries, and every transaction is recorded transparently on the network.
