ERC-20 Tokens: A Beginner's Guide
Welcome to the world of cryptocurrency! This guide will focus on a specific type of cryptocurrency called an ERC-20 token. Don't worry if that sounds complicated – we'll break it down step-by-step. This guide is designed for complete beginners with no prior knowledge of crypto or blockchain technology.
What is a Token?
First, let's understand the difference between a cryptocurrency and a token. Think of a cryptocurrency like Bitcoin or Ethereum as a native currency of its own blockchain. A token, on the other hand, is built *on top* of another blockchain. It uses the existing blockchain's infrastructure and security.
Imagine a shopping mall. The mall itself is the blockchain (like Ethereum). Stores within the mall are the tokens (like Chainlink or Shiba Inu). The mall provides the foundation, security, and infrastructure, but each store operates independently and has its own unique products.
What does "ERC-20" mean?
ERC-20 is a *standard*. It’s a set of rules that token creators follow when building tokens on the Ethereum blockchain. "ERC" stands for "Ethereum Request for Comments," and 20 is simply the proposal number.
Think of it like a standard plug for electrical devices. Because of the standard, any device with that plug can be used in any outlet with that socket. The ERC-20 standard ensures that all ERC-20 tokens can interact with each other and with the Ethereum ecosystem. This includes being traded on decentralized exchanges like Uniswap and stored in crypto wallets that support ERC-20 tokens.
Why are ERC-20 Tokens Popular?
- **Compatibility:** Because they follow a standard, they work with many wallets, exchanges, and other applications.
- **Ease of Creation:** It's relatively easy for developers to create new tokens using the ERC-20 standard.
- **Liquidity:** Many ERC-20 tokens are listed on major exchanges, meaning you can easily buy and sell them.
- **Innovation:** ERC-20 tokens have enabled a huge range of new projects and concepts, including DeFi (Decentralized Finance) and NFTs (Non-Fungible Tokens).
Common ERC-20 Tokens
Here are a few examples of popular ERC-20 tokens:
- **Chainlink (LINK):** Provides data to smart contracts.
- **USD Coin (USDC):** A stablecoin pegged to the US dollar.
- **Shiba Inu (SHIB):** A meme coin that gained popularity.
- **Wrapped Bitcoin (WBTC):** Represents Bitcoin on the Ethereum blockchain.
How to Trade ERC-20 Tokens
Trading ERC-20 tokens is similar to trading any other cryptocurrency. Here’s a basic outline:
1. **Choose an Exchange:** You'll need a cryptocurrency exchange that supports ERC-20 tokens. Some popular options include Register now, Start trading, Join BingX, Open account, and BitMEX. 2. **Create an Account:** Sign up for an account and complete the necessary verification steps (KYC - Know Your Customer). 3. **Deposit Funds:** Deposit either cryptocurrency (like Ethereum) or fiat currency (like USD) into your exchange account. If you deposit fiat, you'll need to convert it to a cryptocurrency to trade ERC-20 tokens. 4. **Find the Trading Pair:** Look for the ERC-20 token you want to trade paired with another currency, usually Ethereum (ETH). For example, LINK/ETH. 5. **Place Your Order:** Choose the type of order you want to place (market order, limit order, etc.). We'll discuss these later in the trading strategies section. 6. **Monitor Your Trade:** Keep an eye on your trade and the market.
Market Orders vs. Limit Orders
These are two of the most common order types:
| Order Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Market Order | Buys or sells the token immediately at the best available price. | Quick execution. | Price can fluctuate, leading to a different price than expected. |
| Limit Order | Buys or sells the token only at a specific price you set. | You control the price. | May not be executed if the price doesn't reach your limit. |

Important Considerations
- **Gas Fees:** Ethereum transactions require "gas," a fee paid to miners to process the transaction. Gas fees can fluctuate significantly. Be aware of these fees before making a trade.
- **Slippage:** The difference between the expected price of a trade and the actual price. This can happen on decentralized exchanges with low liquidity.
- **Wallet Security:** Always use a secure crypto wallet to store your tokens. Consider using a hardware wallet for extra security.
- **Research:** Before investing in any ERC-20 token, do your research! Understand the project, its team, and its potential. Read the whitepaper.
- **Risk Management:** Never invest more than you can afford to lose. Cryptocurrency trading is inherently risky.
ERC-20 vs. Other Token Standards
While ERC-20 is the most popular standard on Ethereum, other blockchains have their own standards:
| Blockchain | Token Standard | Example |
|---|---|---|
| Ethereum | ERC-20 | Chainlink (LINK) |
| Binance Smart Chain | BEP-20 | PancakeSwap (CAKE) |
| Solana | SPL | Serum (SRM) |
Understanding these differences is important if you plan to trade tokens on multiple blockchains. See also: Blockchain interoperability.
