As decentralized finance (DeFi) has matured, standardization has emerged as a critical factor in its evolution, enhancing and safeguarding interoperability—a feature widely regarded as one of the most unique and appealing aspects of DeFi. A prime example of this is the ERC-20 token standard, which has become the backbone of programmable money, defining how market participants can interact with digital currencies at both high and low levels. Standards like ERC-20 benefit all actors in the ecosystem, undeniably making DeFi a more robust and accessible field.
