ERC-20: The Golden Ticket of the Ethereum Wonderland
Picture this: You’ve magically landed in the Ethereum Wonderland, a bustling digital world where tokens roam free and decentralised applications (dApps) spring up like mushrooms after rain. You’ve heard whispers about ERC-20, a mysterious token standard that seems to have everyone buzzing, but what on earth is it? Buckle up, dear reader, because we’re about to dive deep into this enchanted realm and uncover the secrets of ERC-20 in a way that’s easier to digest than a Vegemite sandwich.
ERC-20: The Eccentric Rulebook for Tokens
First things first, ERC-20 stands for Ethereum Request for Comment 20. Yeah, it’s a bit of a mouthful, but think of it as the golden rulebook that token developers on the Ethereum blockchain follow to ensure their tokens can interact seamlessly. It’s like the universal translator for tokens—enabling them to speak the same language, so they can understand one another and play nice.
Now, why is ERC-20 such a big deal? Here’s the scoop: before ERC-20 came along, creating tokens on Ethereum was a bit like a Wild West for developers. Each token had its own quirks and unique code, making interoperability (a fancy word for “working together smoothly”) nearly impossible. Enter ERC-20, an elegant set of rules defining how these tokens should behave, making them as compatible as a well-matched pair of socks.
The Marvelous Obligations of ERC-20 Tokens
Alright, let’s break down what ERC-20 actually dictates. Get ready to meet the six key functions that shape every ERC-20 tokenAlright, folks! Strap in and hold onto your virtual hats because we’re diving into the wonderfully wacky world of “tokens” in the world of crypto and blockchain. So, what on earth is a token? No, it’s…:
1. Total Supply: This function sets the total amount of tokens that will ever exist. Imagine it as the upper limit on a batch of collectible footy cards—no more will be printed once the cap is reached.
2. Balance Of: This checks how many tokens a specific addressIn the world of cryptocurrency and blockchain technology, an address is a string of alphanumeric characters used to send and receive transactions. These addresses are similar to bank account numbers, but they are specifically used in… (think of it as the digital version of a bank account) holds. It’s like peeking into someone’s walletSure! Let’s dive into the wonderful world of wallets in the realm of crypto and blockchain, with a bit of humour to keep things light and engaging. Imagine you’ve just boarded a spaceship headed for the… to see their cash stash.
3. Transfer: This function makes sending tokens to another addressIn the world of cryptocurrency and blockchain technology, an address is a string of alphanumeric characters used to send and receive transactions. These addresses are similar to bank account numbers, but they are specifically used in… as easy as shooting off a text message.
4. TransferFrom: This one allows someone to send tokens on behalf of another addressIn the world of cryptocurrency and blockchain technology, an address is a string of alphanumeric characters used to send and receive transactions. These addresses are similar to bank account numbers, but they are specifically used in…. It’s like giving your mate permission to grab a six-pack for you from the local bottle shop using your card.
5. Approve: Before using TransferFrom, the tokenAlright, folks!

No, it’s… holder needs to give the green light with this function. Think of it as nodding yes when your mate asks if he can borrow your card.
6. Allowance: This function tells you how many tokens you’re authorised to spend on someone else’s behalf. It’s like checking the balance on your pre-approved shopping credit.
Why Should We Care?
Great question. Since its inception, ERC-20 has become the backbone for thousands of tokens. Don’t believe it? As of 2021, there were over 200,000 ERC-20 compatible tokens circulating the globe. Heavy hitters like Chainlink (LINK), USD CoinA term that is gaining popularity in the world of finance and technology is “coin” when used in the context of cryptocurrencies and blockchain. In simple terms, a coin in the world of cryptocurrencies refers to… (USDC), and Basic Attention TokenAlright, folks! Strap in and hold onto your virtual hats because we’re diving into the wonderfully wacky world of “tokens” in the world of crypto and blockchain. So, what on earth is a token? No, it’s… (BAT) all adhere to the ERC-20 standard, proving its immense popularity and utility.
For developers, ERC-20 is a dream come true. Instead of reinventing the wheel each time they create a new tokenAlright, folks! Strap in and hold onto your virtual hats because we’re diving into the wonderfully wacky world of “tokens” in the world of crypto and blockchain. So, what on earth is a token? No, it’s…, they can follow this standard and focus on what makes their tokens unique. It’s like using a cake mix – why measure out the flour and sugar individually when you can just use a proven recipe and customise the frosting?
A Few Hiccups
While ERC-20 is undeniably revolutionary, it’s not without its quirks. One common issue is the accidental loss of tokens when sent directly to smart contracts—kind of like feeding your favourite jumper to a washing machine without checking the settings.
