Create Your Own Digital Currency in Five Minutes or Less

An ERC721 token is a type of non-fungible token (NFT) on the Ethereum blockchain. It follows a standard set of rules called the ERC721 standard, which ensures that every token created with this format is unique, trackable, and secure.

Unlike ERC20 tokens (which are all the same and interchangeable like dollars), ERC721 tokens are one-of-a-kind. Each one has its own identity and metadata — making it ideal for digital collectibles, artwork, membership passes, in-game assets, and more.

Popular NFT projects like CryptoPunks, Bored Ape Yacht Club, and Art Blocks are all ERC721 NFTs. But you don't need to be an artist or a celebrity to create NFTs — anyone can create, own, or sell something unique using ERC721.

In simple terms: 
If ERC20 is like printing your own money, ERC721 is like minting your own collectible or digital asset — each with its own story, design, or purpose.

Turn Digital Items into Collectibles
ERC721 tokens (NFTs) are perfect for representing digital artwork, music, photos, designs, 3D models — anything that needs a unique stamp of ownership. Each token is like a digital certificate that proves you created or own the original.

Example: You can mint a digital painting and sell it as an NFT. Whoever buys it holds the official, verifiable version — just like owning a signed art print.

Attach Files like Images, Music, or Video
Your NFT can point to content such as .jpg, .mp3, .mp4, or 3D files. These files are often stored on decentralized networks like IPFS. The token acts as the public proof of ownership or access.

Example: You can create an NFT for a music track. Fans who own it hold a blockchain-backed version of your song.

Sell or Gift your NFT
You can transfer NFTs to anyone — for free, for sale, or as a reward. Because each one is unique, it’s like giving away a collectible item.

Example: Creators and brands use NFTs to sell digital merch, special editions, or even exclusive experiences.

List Your NFT on Marketplaces
Marketplaces like OpenSea, Rarible, or Foundation make it easy to sell or auction your NFT. These platforms handle the transactions and expose your work to a global audience.

Example: You can mint an NFT and list it on OpenSea — buyers can find it and purchase it using their crypto wallet.

Use it in Games or Metaverse worlds
Many blockchain games and virtual worlds allow NFTs to serve as in-game items, land, avatars, or tools. The player owns these assets — not the game company.

Example: In games like The Sandbox or Decentraland, people use NFTs to own and trade land, outfits, and items.

Prove Ownership and Authenticity
NFTs are recorded on the blockchain forever. This means no one can forge or tamper with your ownership, making them ideal for digital certificates, event tickets, or official records.

Example: A university can issue diplomas as NFTs, allowing graduates to prove their achievement without paperwork.

Unlock Access or Membership
NFTs can act as digital keys. Only wallets that own a specific NFT can access private communities, events, or content.

Example: Projects like VeeFriends and Proof Collective use NFTs as passes to exclusive events, meetups, or benefits.

Trade or Collect for Fun
Many people buy NFTs just to collect them — the same way they collect stamps, baseball cards, or digital art. It’s fun, personal, and often social.

Example: You can build or grow a personal NFT collection, trade with others, or showcase it online.

Create Exclusive Content or Experiences
You can build NFT drops with hidden content, unlockable files, or private experiences that only the NFT holder can access.

Example: A filmmaker could mint an NFT that unlocks access to a behind-the-scenes documentary or private screening.

Build a Community around Your Creations
Just like ERC20 tokens can represent a movement, ERC721 tokens can help you build a loyal fanbase or collector group.

Example: Artists and influencers use NFTs to reward early supporters, recognize contributions, or fund new projects.

In simple terms, a smart contract is a self-executing piece of code that runs on the blockchain. But let’s break that down.

Think of a smart contract as the engine behind your cryptocurrency token — it's the program that defines how your token works and what it can do. This code is stored on the blockchain, meaning it runs automatically and can’t be changed once deployed.

When you create a token using our platform, what we’re actually doing behind the scenes is deploying a smart contract for you. This smart contract includes your token’s name, symbol, and features — and it contains built-in functions like:

mint() – to create more tokens
burn() – to destroy tokens
transfer() – to send tokens

and other optional features depending on what you select (e.g. pausing transfers, adding roles, enabling upgrades)

Your token is the output of this smart contract — it exists because the contract says it should.

And just like your token has a name, the smart contract itself also has an address and identity on the blockchain. You can interact with it using the same wallet you used to create the token — for example, to mint more tokens or manage permissions.

So when you use our platform, you're not just creating a token — you're launching your own custom smart contract, without needing to write a single line of code.

Creating your own token may sound complex — but with our platform, it's simple, fast, and requires no coding at all.

Here's how to get started:

1. Connect Your Wallet
To create a token, you'll need a crypto wallet (like MetaMask or Trust Wallet).
If you don't have one yet, check out our guide: How To Get a Digital Wallet.

Once your wallet is set up, connect it to our platform by clicking “Connect Wallet”. You'll see a popup list of wallets you can use with our platform, including any wallets installed in your browser.

After selecting a wallet, a message popup or notification will appear in your wallet asking you to connect. Once you approve this, a second security authorization popup will appear for you to confirm wallet ownership.

That's it — you're now ready to proceed with the token creation process.

2. Choose a Blockchain Network
There are two types of networks available where you can deploy (create) your cryptocurrency smart contract: Mainnets and Testnets.

If you're ready to launch your project live on the blockchain — where it will be stored permanently and be publicly accessible — you'll want to deploy it on a Mainnet.

If you just want to test how your project will behave without making anything permanent, use a Testnet. Testnets simulate real-world conditions on a blockchain, allowing you to thoroughly test your smart contract before moving to the Mainnet.

For Mainnets (e.g., Ethereum Mainnet, Polygon Mainnet), the differences between networks come down to a few key factors — such as the number of participating computers (nodes), network stability, security, transaction speed, and the cost to deploy and run smart contracts (gas fees).

Think of these networks like different airlines. They all get you to your destination (run smart contracts), but they vary in ticket cost (gas fees), speed and comfort (transaction speed and reliability), and flight availability (network congestion). Some people choose premium options (like Ethereum Mainnet), while others go budget (like Polygon or BSC), depending on their needs and preferences.

One of your most important considerations when choosing a network will likely be gas fees. For example, if typical transactions involving your token are in small amounts (e.g., $0.15 to $100 per transaction), you might prefer a network with lower fees.

On Ethereum Mainnet, gas fees can fluctuate but often range between $5 to $50 or more depending on network congestion — meaning you could end up paying $35 or more in fees for a $25 transaction.

On Ethereum Mainnet, gas fees can fluctuate but often range between $5 to $50 or more depending on network congestion — meaning you could end up paying $35 or more in fees for a $25 transaction. In contrast, other networks like Polygon, Binance Smart Chain, or Arbitrum typically have gas fees as low as $0.01 to $0.10 per transaction — sometimes even less than $0.025.

Choosing a lower-fee network ensures your users aren't discouraged from buying or using your token due to high transaction costs, making your token more practical for everyday use.

 

3. Fill Out Your Token Details
Give your token a name (e.g., “GreenToken”), a symbol (e.g., “GRN”), and choose how many tokens to mint once the smart contract is created. If you don't select the Mintable feature, the number you input here will be the maximum number of tokens that can be Minted by your token's smart contract.

4. Customize Features (Optional)

You may add extra features like:

Mintable - Allows new tokens to be created after deployment. Useful if you plan to increase supply later (e.g., reward programs, ecosystem growth).

Burnable - If you select this feature, your token holders can burn (permanently destroy) their tokens. This can reduce supply and create scarcity over time.

Pausable - Lets you temporarily stop token transfers if needed, useful in case of emergencies or security issues.

Permit - Allows token holders to approve token transfers via signatures without paying gas fees, enabling gasless approvals and improving user experience.

Flash Minting - Lets users mint tokens within a single transaction as long as they are burned (returned) by the end of the transaction. Useful for advanced DeFi operations like arbitrage.

Votes - Enables token holders to delegate their voting power and ensures votes are based on historical token balances, helping secure and fair on-chain governance.
 

• Block Number - Token balances are snapshotted based on the block number at voting time, preventing users from transferring tokens to manipulate voting power.
• Timestamp - Token balances are snapshotted based on timestamps instead of block numbers, useful for blockchain systems that support time-based voting.

Access Control - Restricts who can access specific functions of the contract and under what conditions. Offers more granular security and permissions.
 

• Ownable - Grants admin control to your wallet, allowing you to perform important privileged actions like minting, pausing, or upgrading (only you as the owner).
• Roles - A flexible system where each privileged action has its own role, and multiple accounts can be authorized for each role. Great for larger teams or organizations.
• Managed - Allows a central managing contract to decide which accounts can use certain functions, based on a customizable access policy.

Upgradeability - (Coming Soon) Lets you deploy your token behind a proxy so it can be upgraded in the future. Normally, smart contracts are immutable once deployed.
 

• Transparent Proxy - Uses a separate ProxyAdmin contract to manage upgrades. It's slightly heavier but allows smoother upgrade management. Compatible with Beacon proxies as well.
• UUPS Proxy - A lighter proxy mechanism where upgrade logic is embedded in your contract. Gives you full control over who can authorize upgrades, but requires a bit more careful implementation.

Security Contact - Allows you to specify a contact address where users can report security issues. This will only appear if your contract metadata is verified.

5. Review & Confirm
Double-check your settings. When you're ready, click “Create Token”. Your wallet will ask you to approve the transaction and pay a gas fee.

6. Your Token Is Live!
In just a few moments, your smart contract is deployed and your token is created on the blockchain. You'll see your token's smart contract address, and you can view it on a block explorer like Etherscan.

What Is a Digital Wallet?
A digital wallet (also called a crypto wallet) is a secure tool that lets you store, send, receive, and manage cryptocurrencies and digital assets like tokens or NFTs. Think of it as your personal bank account for the blockchain — but fully under your control.

Why You Need a Digital Wallet
To create, own, or interact with cryptocurrency tokens and decentralized applications (dApps), you need a digital wallet. It’s how you:

• Receive and store your tokens
• Send tokens to others
• Connect to blockchain apps and platforms
• Prove ownership of assets like NFTs

Without a wallet, you can't securely participate in the crypto world.

Types of Digital Wallets
There are different kinds of wallets, but for beginners, the most common are:

• Browser Wallets – Extensions for your web browser (e.g., MetaMask) that make it easy to interact with websites and apps.
• Mobile Wallets – Apps you install on your smartphone (e.g., Trust Wallet) that give you access on the go.
• Hardware Wallets – Physical devices (like Ledger or Trezor) that store your crypto offline for maximum security. Best suited for advanced users.

For getting started quickly with CosmoTitan, browser wallets are the easiest to set up.

Popular Wallets for Beginners
Here are some trusted wallets that are beginner-friendly and support popular blockchains like Ethereum:

• MetaMask (Browser + Mobile)
• Trust Wallet (Browser + Mobile)
• Coinbase Wallet (Browser + Mobile, not the same as Coinbase exchange website/app)
• Rainbow Wallet (Browser + Mobile, focused on simplicity and NFTs)

These wallets are free to use and widely supported across crypto platforms.

How to Set Up a Digital Wallet
Setting up a wallet is quick and doesn’t require personal information:

• Download the wallet from the official website or app store.
• Install the wallet on your browser or mobile device.
• Create a New Wallet — you’ll be given a recovery phrase (12 or 24 secret words). Write these down and store them securely.
• Set a Password for daily access.
• Backup Your Wallet by safely saving your recovery phrase. This is the only way to restore your wallet if you lose your device.

Now you’re ready to send, receive, and manage your crypto.

Important Security Tips

• Never share your recovery phrase. Anyone with it can access your wallet.
• Beware of phishing sites. Always download wallets from official sources.
• Backup properly. Store your recovery phrase offline and in a secure place.

Your wallet’s security is your responsibility — treat it like you would your bank PIN or password.

How to Add Funds to Your Wallet
Once your wallet is set up, you can add funds:

• Buy crypto directly inside the wallet app (many support credit card purchases)
• Transfer crypto from another wallet or exchange (e.g., send ETH from Coinbase to your MetaMask address)

You'll usually need a little ETH (Ethereum) to pay for transaction fees (called gas fees) if you’re working on the Ethereum blockchain.

What You Can Do With Your Wallet
With your wallet set up, you can:

• Create and manage your own tokens
• Buy and sell NFTs
• Connect to dApps and DeFi platforms
• Send and receive crypto payments
• Participate in blockchain-based communities

A wallet unlocks everything the blockchain has to offer — it’s your passport to Web3.
