Frequently Asked Questions

What is the ERC-20 token standard?

ERC-20, proposed by Fabian Vogelsteller in November 2015, defines a standard interface for fungible tokens on Ethereum. It specifies functions like transfer, approve, and balanceOf, enabling interoperability across wallets, exchanges, and DApps. It became the foundation for the 2017 ICO boom.

What is ERC-721 and how does it enable NFTs?

ERC-721, finalized in January 2018, is the standard for non-fungible tokens on Ethereum. Unlike ERC-20 tokens, each ERC-721 token has a unique ID, making it suitable for representing ownership of distinct digital or physical assets. It enabled CryptoKitties, art NFTs, and digital collectibles.

What was the Ethereum Merge?

The Ethereum Merge, completed on September 15, 2022, transitioned Ethereum from proof-of-work to proof-of-stake consensus. It merged the existing execution layer with the Beacon Chain (launched December 2020), reducing Ethereum's energy consumption by approximately 99.95% without any downtime.

What is EIP-1559 and how did it change Ethereum?

EIP-1559, activated in August 2021's London upgrade, introduced a base fee mechanism that burns ETH with each transaction instead of paying all fees to miners. This made gas fees more predictable and introduced deflationary pressure on ETH supply, fundamentally changing Ethereum's monetary policy.

How do Ethereum Improvement Proposals (EIPs) work?

EIPs are the formal process for proposing changes to the Ethereum protocol. Anyone can submit an EIP, which goes through draft, review, and finalization stages. Core EIPs require consensus among client teams and are activated through coordinated network upgrades (hard forks).
