Token

A token is a digital asset built on an existing blockchain platform rather than having its own native blockchain. While cryptocurrencies like Bitcoin and Ethereum operate on their own blockchains, tokens are created through smart contracts on established networks, most commonly Ethereum.

Tokens vs Coins: Key Differences

Cryptocurrencies (Coins): Native to their own blockchain (BTC on Bitcoin, ETH on Ethereum, SOL on Solana). Used primarily for transactions and paying network fees.

Tokens: Built on existing blockchains using smart contracts. Can represent virtually anything—from company shares to voting rights to in-game items. Don't require building an entire blockchain infrastructure.

Creating a cryptocurrency requires launching a blockchain with nodes, consensus mechanisms, and network security. Creating a token requires deploying a smart contract—achievable in hours rather than months.

Token Standards

Blockchain platforms use standardized templates for token creation, ensuring compatibility across wallets and applications:

ERC-20 (Ethereum): Fungible token standard for currencies and utility tokens. Each token is identical and interchangeable. Used by USDT, LINK, UNI, and thousands of projects. Defines functions like transfer(), balanceOf(), and approve().

ERC-721 (Ethereum): Non-fungible token (NFT) standard where each token is unique with distinct properties. Used for digital art, collectibles, and proof of ownership.

ERC-1155 (Ethereum): Multi-token standard allowing both fungible and non-fungible tokens in one contract. Efficient for gaming with various asset types.

BEP-20 (BNB Chain): Similar to ERC-20 but on Binance's blockchain. Lower transaction costs, compatible with Ethereum tools.

SPL Tokens (Solana): Solana's token standard, extremely fast and cheap. Used by major Solana projects.

Each standard defines required functions and events, ensuring tokens work across the ecosystem without custom integration.

Types of Tokens

Utility Tokens: Provide access to products or services within a protocol. Filecoin (FIL) buys decentralized storage. Chainlink (LINK) pays for oracle services. BAT rewards Brave browser users. Utility tokens aren't investments per se but functional tools within ecosystems.

Governance Tokens: Grant voting rights on protocol decisions. UNI (Uniswap), COMP (Compound), and MKR (Maker) holders vote on protocol upgrades, fee structures, and treasury spending. Distribute power among users rather than centralizing in development teams.

Security Tokens: Represent traditional securities (stocks, bonds, real estate) on blockchain. Subject to securities regulations. Offer programmable compliance, 24/7 trading, and fractional ownership. Still emerging due to regulatory complexity.

Stablecoins: Pegged to external assets (usually USD). USDC and USDT are backed by dollar reserves. DAI maintains $1 peg through algorithmic mechanisms. Essential for crypto trading without converting to fiat.

Wrapped Tokens: Represent assets from one blockchain on another. WBTC (Wrapped Bitcoin) brings Bitcoin to Ethereum for DeFi use. Maintains 1:1 backing with original asset through custodians.

Social Tokens: Represent creators, communities, or personal brands. Musicians issue tokens for exclusive content. Communities create tokens for membership benefits. Experiment in monetizing influence and community.

Gaming Tokens: In-game currencies and items as tradeable tokens. Players truly own assets, usable across games or sold on open markets. Axie Infinity's AXS/SLP, Decentraland's MANA, and The Sandbox's SAND are examples.

Token Economics (Tokenomics)

Token design determines project success. Key considerations:

Total Supply: Fixed (21M Bitcoin) or inflationary (Ethereum post-merge has small inflation). Affects scarcity and long-term value.

Distribution: How tokens are allocated at launch. Common splits: Team/advisors (10-20%), investors (20-30%), treasury (20-30%), public sale (10-20%), ecosystem rewards (20-30%). Heavily concentrated ownership creates centralization risks.

Vesting Schedules: Time-locks preventing immediate token sales. Team tokens often vest over 2-4 years. Prevents dumps that crash prices.

Utility and Value Accrual: How tokens capture value. Transaction fees? Protocol revenue sharing? Staking rewards? Tokens without clear utility struggle to maintain value.

Incentive Alignment: Do tokenomics encourage beneficial behavior? DeFi protocols incentivize liquidity provision. Governance tokens encourage active participation.

Poor tokenomics doomed many projects. Excessive team allocations, infinite inflation without burn mechanisms, or purely speculative value propositions often fail.

How Tokens Are Created

On Ethereum, creating an ERC-20 token requires deploying a smart contract defining:

Token name and symbol
Total supply
Decimal places (usually 18)
Transfer functions
Approval mechanisms

Tools like OpenZeppelin provide battle-tested templates. A basic token contract can be deployed in minutes, though production tokens need thorough audits.

The deployment process:

Write smart contract defining token properties
Compile to bytecode
Deploy to blockchain (costs gas fees)
Contract address becomes token identifier
Token appears in wallets and can be traded

Token Distribution Methods

Initial Coin Offerings (ICOs): 2017-era public sales, mostly unregulated. Raised billions but many were scams. Now largely replaced by regulated alternatives.

Initial DEX Offerings (IDOs): Launch tokens on decentralized exchanges. More democratized access but still risky.

Airdrops: Free token distribution to users, often rewarding early protocol adopters. Uniswap's 400 UNI airdrop (worth $1,000+ at launch) set the standard.

Liquidity Mining: Distribute tokens to users providing liquidity or using protocols. Incentivizes adoption but can attract mercenary capital.

Token Sales (Private/Public): Selling tokens to investors pre-launch at discounted prices. Often includes vesting to prevent immediate selling.

Fair Launches: No pre-mine or pre-sale—everyone mines or earns tokens simultaneously. Bitcoin pioneered this model.

Token Regulation and Securities Law

The SEC's "Howey Test" determines if tokens are securities:

Investment of money
Common enterprise
Expectation of profits
Derived from others' efforts

Many tokens arguably qualify as securities, creating legal risks. The industry debates whether sufficient decentralization exempts tokens from securities laws.

Security tokens explicitly embrace regulation, registering offerings and complying with securities law. Utility tokens try to avoid classification by emphasizing function over investment.

Regulatory uncertainty remains among the biggest challenges facing token projects, with different jurisdictions taking vastly different approaches.

Token Burning

Projects permanently destroy tokens to reduce supply. Burning mechanisms include:

Transaction fee burns (EIP-1559 burns ETH base fees)
Buyback and burn programs (using protocol revenue)
Deflationary tokenomics with automatic burns

Burning creates deflationary pressure, potentially increasing remaining token values. However, burning alone doesn't create value—underlying protocol utility matters most.

Token Migration and Upgrades

Projects occasionally migrate tokens to new contracts for:

Security fixes
Feature additions
Blockchain changes

Migrations require users to exchange old tokens for new ones, creating friction and potential user loss. Well-executed migrations include long transition periods, clear communication, and automatic exchange mechanisms where possible.
