With smart contracts, you simply insert cryptocurrency (such as Bitcoin) into the system (like a vending machine) to execute the contract. While ERC-20, ERC-721, and ERC-1155 have become staples, the blockchain world is always cooking up something new. Several emerging token standards aim to improve upon existing models or address specific needs that aren’t fully met by the current ERC standards. These new standards often focus on enhanced functionality, improved efficiency, or specialized use cases. After a boom in 2018, the year 2019 saw a further increase in the acceptance and in applications of the ERC20 token standard on an international scale as the utilisation of Ethereum smart contracts is growing. The ICO space is becoming increasingly more regulated while some countries are currently banning ICOs all together.
- That way, holders can use their BTC for activities such as staking and lending, which are impossible on its native blockchain.
- But as DeFi continues to expand, we might see more uses for these cryptocurrencies, particularly when it comes to staking, lending, and yield farming.
- The ability to quickly convert a digital currency or token into another asset or cash without affecting its price.
A basic implementation of ERC-20 tokens
It is perhaps easiest to think of ERC20 as a set of instructions that a smart contract on the Ethereum network must include. The ERC-20 token standard allows developers to create their own tokens on the Ethereum network. It has provided an easier route for companies to develop blockchain products instead of building their own cryptocurrency. ERC20 tokens operate on the Ethereum blockchain, which is renowned for its robust smart contract capabilities and wide adoption. The network is supported by the Ethereum Virtual Machine (EVM), allowing for complex contract operations and a broad range of decentralized applications (dApps).

«Token» and «Cryptocurrency» are often used interchangeably; all cryptocurrencies are tokens, but not all tokens are cryptocurrencies. Token, in the context of ERC-20 compliance, simply means a blockchain representation of something that meets the standards set by the Ethereum community to be considered a smart contract standard-compliant token. This means that other tokens can run on top of it, and decentralized applications (dapps) can be built atop it using smart contracts. ERC20, which stands for “Ethereum Request for Comments 20,” is a technical standard used for issuing and managing tokens on the Ethereum blockchain.

This compatibility enhances user experiences by providing uniform interfaces and functionalities across various applications and platforms, simplifying token management and utilization for developers and users. ERC-20 has been one of the key driving forces of the Ethereum ecosystem, and a boon for the blockchain space as a whole. By creating a common standard for participation in the blockchain industry, ERC-20 facilitated widespread adoption of decentralized technology. Its implementation is an example of the community-driven governance of Ethereum, and its network effect ensures that Ethereum currently is the focal point of blockchain development.
All of which facilitates token creation and interoperability in multi-chain environments. Of the mandatory and optional functions that the ERC-20 proposal outlined, the “transfer” function is the most foundational. This function is embedded in Ethereum smart contracts to enable direct token transfers from a sender’s address to a specified Ethereum address.

Moves the amount of tokens from the function caller address (msg.sender) to the recipient address. The ERC-20 standard allows an address to give an allowance to another address to be able to retrieve tokens from it. This getter returns the remaining number of tokens that the spender will be allowed to spend on behalf of owner.
