Fungible Tokens (ERC20)


ERC20 Fungible Tokens are digital assets that adhere to the ERC20 standard. They represent a standardized form of tokenization commonly used for creating fungible assets such as currencies, loyalty points, and utility tokens. Fungible tokens are identical and interchangeable, meaning that each token holds the same value and can be exchanged on a one-to-one basis with other tokens of the same type.


  1. Interchangeability: ERC20 Fungible Tokens are interchangeable with each other, meaning that one token is equivalent in value to another token of the same type. This interchangeability facilitates seamless transactions and liquidity within the token ecosystem.

  2. Divisibility: Fungible tokens are divisible into smaller units, allowing for precise transactions even with fractional amounts. The divisibility of ERC20 tokens is defined by the number of decimal places specified during token creation, typically ranging from 0 to 18.

  3. Standardization: ERC20 Fungible Tokens adhere to a common set of rules and functions defined by the ERC20 standard. This standardization ensures compatibility with various wallets, exchanges, and smart contracts, enhancing interoperability and usability.

  4. Smart Contract Compliance: ERC20 Fungible Tokens are deployed as smart contracts on the blockchain, enabling programmable features such as token transfers, approvals, and allowances. These smart contracts govern token behavior and enforce rules specified by the token issuer.

Use Cases

  1. Digital Currencies: ERC20 Fungible Tokens are widely used as digital currencies within decentralized applications (DApps), enabling peer-to-peer transactions, remittances, and payments without the need for intermediaries.

  2. Loyalty and Rewards Programs: Businesses utilize ERC20 tokens to create loyalty and rewards programs, incentivizing customer engagement and retention through token-based incentives and discounts.

  3. Utility Tokens: Many blockchain projects issue ERC20 tokens as utility tokens to access and pay for services within their ecosystems. These tokens grant holders specific rights or privileges within the platform, such as voting, staking, or accessing premium features.

  4. Token Offerings (ICOs/STOs): ERC20 Fungible Tokens are commonly used for Initial Coin Offerings (ICOs) or Security Token Offerings (STOs) as a means of crowdfunding and token distribution. Investors receive tokens representing ownership or participation in the project.


  1. Accessibility: ERC20 Fungible Tokens provide a straightforward method for token creation and distribution, allowing businesses and projects of all sizes to tokenize assets and engage with their communities.

  2. Interoperability: Standardization under the ERC20 standard ensures compatibility with a wide range of wallets, exchanges, and decentralized applications, fostering a vibrant ecosystem of tokenized assets and services.

  3. Scalability: Fungible tokens offer scalability for decentralized applications by enabling efficient and cost-effective transactions on the blockchain. Projects can leverage existing infrastructure and tools to integrate token functionality into their platforms.

  4. Transparency: The immutable and transparent nature of blockchain technology ensures that token transactions and ownership are publicly verifiable, enhancing trust and accountability within the ecosystem.


ERC20 Fungible Tokens play a crucial role in the tokenization of assets and the development of decentralized economies. With their standardized format, programmable features, and widespread adoption, ERC20 tokens continue to empower businesses, developers, and users to participate in the growing digital economy powered by blockchain technology.
