What is ERC-20: Understanding Smart Contracts in Blockchain

·


The Universal Language of Ethereum Tokens

ERC-20 serves as the standard protocol for tokens on the Ethereum blockchain, akin to a universal language that ensures seamless interoperability. This set of rules enables tokens to interact with each other and with smart contracts efficiently.

Key Features of ERC-20 Tokens:


Stablecoins: USDC and USDT – The ERC-20 Powerhouses

Two prominent ERC-20 tokens, USDC and USDT, stand out as stablecoins—digital assets pegged to the US dollar. Unlike volatile cryptocurrencies (e.g., BTC, ETH), their value remains stable, making them ideal for:

  1. Cross-Border Payments: Instant transfers without traditional banking fees.
  2. Trading Hedges: Safeguard assets during market volatility.
  3. DeFi Applications: Serve as collateral or liquidity in lending protocols.
