ERC-20 Token: What It Is and Why It Powers Most Crypto Projects
When you hear about a new crypto coin like ERC-20 token, a standardized digital asset built on the Ethereum blockchain that lets different apps talk to each other. Also known as Ethereum token standard, it's the reason you can send Howl City, Schrödinger, or HGT tokens without needing a new network for each one. This isn’t just tech jargon—it’s the invisible plumbing behind almost every coin you’ve heard of. If it runs on Ethereum and isn’t Bitcoin, it’s probably an ERC-20 token.
ERC-20 isn’t a coin itself. It’s a rulebook. Think of it like a universal USB port: no matter if you plug in a phone, camera, or headset, they all fit because they follow the same design. Same with ERC-20. It says every token must have a name, symbol, total supply, and functions to send, receive, and check balances. That’s why your wallet can handle 100 different tokens without learning a new system each time. But here’s the catch: following the rules doesn’t mean the project is real. Look at Howl City (HWL) or Schrödinger (SGR)—both are ERC-20 tokens with zero team, zero utility, and zero future. The standard makes them possible. It doesn’t make them trustworthy.
Behind every ERC-20 token is a smart contract, a self-executing code on Ethereum that enforces token rules automatically. That’s what lets you trade tokens on decentralized exchanges like Quickswap or FEG Exchange. But if the code has bugs—or worse, if the owner can freeze or mint more tokens—you’re at risk. That’s why some tokens, like MMF from MM Finance, turn out to be scams: they use the ERC-20 format to look real, but the contract hides traps. And when you see an airdrop, a free distribution of tokens to wallets, often used to kickstart adoption for HGT or BIRD, always check the contract address. Fake airdrops copy the look of real ones but steal your keys.
ERC-20 tokens thrive because they’re easy to build. That’s why Southeast Asia sees so many of them—low cost, fast launch, no need for a new blockchain. But ease doesn’t equal value. The same standard that powers real DeFi apps also lets scammers drop fake coins overnight. Your job isn’t to avoid ERC-20 tokens. It’s to ask: Who’s behind this? Is the code open? Is there real activity? Is this just another coin with no game, no team, and no reason to exist? The posts below dig into exactly that. You’ll see real examples, broken projects, and how to spot the difference before you lose money.
