Etherscan officially launched in August 2015.

This Ethereum block explorer has grown into a cornerstone of blockchain analysis since its debut. Founded by Matthew Tan in Malaysia, it quickly became one of the longest-running independent Ethereum projects.

Launch Timeline

Etherscan's key early milestones unfolded rapidly:

  • August 2015 : Core platform launched as the primary Ethereum block explorer.
  • September 2015 : API services rolled out for developers.

A Twitter post even pins the exact date as August 12, 2015, highlighting its role in early Ethereum history.

Historical Context

Back in 2015, Ethereum was still in its infancy post-mainnet launch (July 30), making Etherscan vital for tracking transactions and contracts. It filled a critical gap, evolving from a simple explorer to a full analytics suite with tools like gas trackers and verified signatures by 2018.

Its staying power shines through a 2025 "10 Years of Etherscan" campaign, celebrating its endurance amid Ethereum's massive growth.

Why It Matters Today

Etherscan's 2015 launch positioned it as the go-to for Ethereum transparency, much like how early tools shaped Bitcoin's ecosystem. No major disputes exist on the date—sources align on mid-2015.

TL;DR: August 2015, specifically around August 12 per community notes.
