It’s a bit like watching the internet evolve – you know it’s going to be big, but you can’t quite picture exactly what it will become. Audits are essential to identify and fix potential issues before deployment. It’s like building a house – you need to make sure the foundation is solid before you start adding walls. Formal verification methods can also be used to mathematically prove the correctness of a smart contract.
What are blockchain token standards?
Just like Bitcoin, Litecoin, and any other cryptocurrency, ERC20 tokens are blockchain-based assets that have value and can be sent and received. The difference is that instead of running on their own blockchain, these tokens are issued on the Ethereum network. This means they’re hosted by Ethereum addresses and are sent using Ethereum transactions. Developers can create ERC-20 tokens by deploying smart contracts on the Ethereum network.
- There are several types of blockchain token standards, each designed for different purposes.
- Cryptocurrency token standards enable interoperability so that native coins of one blockchain can be transferred to and traded on another.
- A contributing tech reporter at CoinDesk, Alyssa Hertig is a programmer and journalist specializing in Bitcoin and the Lightning Network.
- Using computer code, the developers can set the maximum supply of their tokens and set rules for how they are issued and traded.
- ERC-20 tokens are digital assets that can be created by anyone but are mostly made by organizations and tech-focused companies.
- The project is focused on providing reliable data feeds to enable smart contract execution.

This accessibility has helped accelerate the Ethereum network’s growth, driving innovation and expanding the blockchain’s capabilities. Despite inherent risks and challenges, the ERC20 standard continues to evolve, with ongoing efforts to address scalability, security, and regulatory concerns.
Is ERC20 the Same As Ethereum?
“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.
What are the characteristics of ERC-20?
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.
Discover what crypto OTC trading is, and how it can offer a secure, private way to execute trades outside of traditional exchanges. The regulatory landscape surrounding ERC-20 tokens remains uncertain, with some regulatory bodies yet to define their classification and oversight. Chances are you have found an interesting Ethereum project and you are looking to receive its native ERC-20 token. If this describes your current predicament, then you are in the right place.
