What Is a Crypto Token?
A crypto token is a digital asset built on top of an existing blockchain, such as Ethereum or Solana.
Unlike coins, which are native to a blockchain, tokens represent assets, rights, or utilities and rely on smart contracts for functionality.
They can represent anything from governance power in a DAO to ownership of a real-world asset like real estate or artwork. Tokens are widely used in DeFi, gaming, and NFT ecosystems.
How Does a Crypto Token Work?
Crypto tokens function by using smart contracts deployed on a blockchain like Ethereum, Binance Smart Chain, or Solana. These smart contracts define how tokens are created, managed, and transferred.
Smart contracts enforce rules: Each token follows a standard (e.g., ERC-20 or BEP-20) that dictates its supply, transfer logic, and approval process.
Balances tracked on the contract: Unlike coins like Bitcoin, tokens don't modify the base blockchain ledger. Instead, balances are stored and updated within the token’s smart contract.
Transactions require gas fees: Sending tokens requires blockchain interaction, so users must pay gas fees in the network’s native coin (e.g., ETH for Ethereum-based tokens).
Custom utility: Developers can program unique behaviors, such as staking rewards, governance votes, or automatic burns.
As a result, crypto tokens are highly versatile and can power everything from DeFi lending apps to NFT platforms—without the need to build a new blockchain from scratch.
Crypto Coins vs. Tokens: What’s the Difference?
Although the terms are often used interchangeably, crypto coins and tokens serve different functions and operate under distinct technical conditions. Here's how they compare:
-
Native Blockchain vs. Built on Existing Chains
Coins like Bitcoin and Ethereum operate directly on their own blockchains. Tokens, however, are created on top of existing chains.
Crypto coins run on native blockchains like Bitcoin (BTC) or Ethereum (ETH).
Tokens like USDC or Uniswap (UNI) are built using standards such as ERC-20 or BEP-20.
Creating a coin typically requires launching a blockchain, while creating a token uses existing networks.
Therefore, coins are foundational to their ecosystems, while tokens leverage established infrastructure to deliver specific functionalities.
-
Primary Use Case
Coins usually function as digital money or a store of value, while tokens can represent much more—like assets, access, or governance rights.
Bitcoin is mainly used as a store of value or medium of exchange.
Utility tokens like BAT give access to services within a platform.
Governance tokens such as AAVE allow users to vote on project proposals.
Because of this, tokens tend to offer broader functionality than just payments or transfers.
-
How They’re Transacted and Stored
Coins are transferred through their blockchain, while tokens rely on smart contracts within a host chain like Ethereum.
Coin transfers involve direct changes to the blockchain’s ledger.
Token transfers interact with smart contracts that manage balances.
Wallets like MetaMask can store both, but the mechanics differ under the hood.
As a result, using tokens often involves gas fees from the host blockchain, especially in high-traffic networks.
-
Mining vs. Token Issuance
Coins are often mined or validated through blockchain consensus mechanisms, while tokens are issued directly by developers.
Bitcoin and Litecoin use mining (Proof of Work).
Tokens like Chainlink (LINK) are issued during token launches or ICOs.
Token supplies are managed via smart contract rules, not miners.
This makes token creation quicker and more flexible, but also puts more control in the hands of project founders.
Utility Tokens vs. Security Tokens: What's the Difference?
Utility tokens give holders access to a product or service, while security tokens represent ownership or investment—similar to traditional securities. The distinction matters for both regulation and risk.
Utility tokens are common in decentralized applications, whereas security tokens are subject to stricter financial laws and oversight, especially in the United States.
Feature | Utility Tokens | Security Tokens |
|---|---|---|
Regulation | Light or none (unless violating laws) | Strictly regulated by securities authorities |
Purpose | Access services, staking, governance | Ownership, dividends, asset-backed rights |
Launch Method | ICOs, platform incentives | STOs (Security Token Offerings) |
Investor Rights | Limited rights | Rights similar to shareholders |
Popular Examples | UNI, AAVE, BAT | INX, tZERO, Exodus Tokens |
Examples of Popular Crypto Tokens
Tokens power many of today’s most used blockchain platforms. Here are some well-known tokens across various sectors:
Uniswap (UNI): A governance token for the Uniswap DEX, allowing holders to vote on protocol changes.
Chainlink (LINK): A utility token used to pay for data feeds within the Chainlink oracle network.
Aave (AAVE): Used for governance and staking within Aave’s decentralized lending system.
Basic Attention Token (BAT): Rewards users and publishers in the Brave browser ecosystem.
Tether (USDT): A stablecoin pegged to the U.S. dollar, widely used for trading and transferring funds quickly.
These tokens showcase a broad range of use cases, spanning DeFi, advertising, governance, and stable digital payments.
Risks of Investing in New Crypto Tokens
While new tokens offer exciting opportunities, they also come with elevated risks investors must understand.
Lack of Regulation: Many new tokens aren't registered with regulatory bodies, which can lead to fraud or sudden shutdowns.
Low Liquidity: Smaller tokens often have low trading volumes, making them hard to sell without slippage.
Pump-and-Dump Schemes: Projects may inflate prices using hype, only for early insiders to dump their holdings.
Smart Contract Vulnerabilities: Poorly coded contracts can be exploited, leading to loss of funds.
Because of these risks, it’s essential to conduct thorough research, use trusted platforms, and avoid chasing hype without fundamentals.
FAQ
Most tokens on Ethereum follow the ERC-20 or ERC-721 standard. These formats ensure compatibility with wallets, exchanges, and dApps.
Yes. Some projects launch multi-chain tokens or use bridges to allow the same token to exist on different networks like Ethereum and Binance Smart Chain.
Stablecoins are a type of token specifically designed to maintain a fixed value, usually pegged to fiat currencies. Other tokens may fluctuate in price or offer different functions.
A token burn is when a project removes tokens from circulation, typically by sending them to an unusable address. This is done to reduce supply and increase scarcity.
No. Some tokens are purely speculative or used for fundraising. Utility depends on the token’s purpose within its ecosystem.
Yes, platforms like Ethereum allow you to create a token using smart contracts, but you’ll need coding knowledge or a token-generation service.
Tokenomics refers to the economic design of a token, including its supply, distribution, incentives, and how it's used within a network.
Sending tokens still requires gas fees in the blockchain’s native coin (like ETH), because the transaction interacts with a smart contract.
Yes. In many jurisdictions, buying, selling, or using tokens can trigger taxable events. Check with a local tax advisor or authority.
