What Is Etherscan?
Definition
Etherscan is the primary block explorer for Ethereum — used to verify contracts, check transactions, view token holders, and confirm ownership status of ERC-20 tokens.
Etherscan (etherscan.io) is the Ethereum blockchain's official explorer. Basescan (basescan.org) is the equivalent for Base, built by the same team.
- Contract verification — upload Solidity source code so anyone can read it. CoinDevTools contracts are automatically verified.
- Token tracker — view total supply, holders, transfers, and price (once listed on a DEX)
- Read/Write contract — interact with smart contract functions directly from the browser
- Ownership check — verify if ownership is renounced (owner set to zero address)
- LP token tracking — view liquidity pool token balances and burns
After creating a token on CoinDevTools (Ethereum or Base): 1. Search the contract address on Etherscan/Basescan 2. Check "Contract" tab → verify source code matches 3. Check "Read Contract" → call owner() to verify ownership is renounced 4. Check "Holders" tab → view token distribution 5. Share the Etherscan link with your community as proof of legitimacy

Block Explorer
A block explorer is a web tool that lets you search and view all transactions, addresses, tokens, and smart contracts on a blockchain — like a search engine for on-chain data.
ERC-20 Token
ERC-20 is the most widely used token standard on Ethereum and EVM-compatible chains, defining how fungible tokens are created and transferred.
Renounce Ownership
Renouncing ownership permanently removes the admin (owner) role from an ERC-20 smart contract, making it fully decentralized and immutable.
Smart Contract
A smart contract is a self-executing program stored on a blockchain that automatically enforces the rules of an agreement when predefined conditions are met.
