What is Token?
A token is a unit of value recorded on a blockchain, representing anything from a currency and a utility credit to a share in an asset. Tokens are created and transferred according to rules set by a smart contract or protocol.
Also known as: crypto token · digital token · coin
In plain terms
On a blockchain, a token is an entry in a ledger saying a certain address owns a certain amount of something. What that something is depends on the project: money, access rights, governance votes, or a claim on a real-world asset.
The word is broad by design. Whether a token is a security, a payment instrument or something else is decided by its design and by regulation, not by what it is called.
How it works
Most tokens follow published standards, such as ERC-20 for fungible tokens on Ethereum, which define how balances and transfers work so wallets and exchanges can support them uniformly.
A project issues tokens by deploying a contract that mints a supply and assigns it to initial holders. From then on, transfers simply update balances on the chain.
Tokens can carry extra logic: transfer restrictions, vesting, approval flows or compliance checks such as ERC-3643's identity requirements.
Example
Hypothetical: a software company issues 1,000,000,000 utility tokens to power discounts in its product and, separately, 5,000,000 security tokens representing profit participation in another entity, in two different contracts with different rules — the word token alone does not tell you what you hold.
Why it matters for founders and investors
For investors, the first step in evaluating any token is understanding what rights it actually confers: cash flows, votes, access, or nothing enforceable. Marketing names are unreliable; the contract and the legal documents are not.
For founders, token design decisions — supply, standards, transfer rules — affect everything from exchange listings to whether the token needs securities treatment.
Common misconceptions
Token and coin are often used interchangeably, but strictly speaking a coin like bitcoin runs on its own blockchain, while a token is issued on an existing one. The distinction rarely changes the analysis.
A token with no transfer restrictions or legal wrapper is not automatically free of securities laws; classification depends on how it is sold and what it promises.
Frequently asked questions
What is the difference between a coin and a token?
A coin is the native currency of its own blockchain, such as bitcoin or ether. A token is issued on top of an existing blockchain, such as an ERC-20 token on Ethereum, and depends on that chain for security.
Are all tokens investments?
No. Some tokens exist to pay network fees, represent loyalty points or grant software access. Whether a token is an investment depends on its design, how it is marketed and the applicable regulation.
