Token (Crypto)

In cryptocurrency, a token is a digital asset that is created and operates on top of an existing blockchain platform rather than having its own native blockchain. The most common platform for token creation is Ethereum, where tokens follow standardized formats like ERC-20 (fungible tokens) and ERC-721 (non-fungible tokens). This distinction between coins (native to their own blockchain) and tokens (built on existing blockchains) is fundamental to understanding the crypto ecosystem.

Tokens serve various purposes depending on their design. Utility tokens provide access to a product or service within a specific ecosystem (e.g., LINK for Chainlink oracle services). Governance tokens grant holders voting rights in protocol decisions (e.g., UNI for Uniswap governance). Security tokens represent ownership in real-world assets like real estate or company equity. Stablecoins are tokens pegged to fiat currencies. Wrapped tokens represent assets from one blockchain on another (e.g., Wrapped Bitcoin on Ethereum).

The ease of creating tokens has been both a blessing and a curse for the crypto ecosystem. Anyone can create a token using a smart contract template in minutes, which has democratized fundraising and innovation but has also enabled countless scams and worthless projects. When evaluating tokens, investors should examine the token's utility within its ecosystem, the supply schedule (fixed vs. inflationary), distribution (how concentrated holdings are), and whether the token captures value from the protocol's growth.
