📢 Scroll Explorer Migration: Transitioning to Blockscout
We are migrating our block explorer backend from Etherscan to Blockscout to better serve the Scroll ecosystem.
✅ Automatic Redirections (No Action Required for Web Users)
Starting soon, our official domains will automatically redirect to the new Blockscout-powered interfaces:
- Mainnet: scrollscan.com → scroll.blockscout.com
- Sepolia: sepolia.scrollscan.com → scroll-sepolia.blockscout.com
🛠️ New Blockscout API Endpoints
Developers using our APIs should begin migrating to the following endpoints:
- Scroll Mainnet API: https://api.blockscout.com/534352
- Scroll Sepolia API: https://api.blockscout.com/534351
⚠️ Legacy Etherscan Access (Retiring April 16th, 23:59 UTC)
The Etherscan-hosted version will remain accessible via these temporary links until April 16th, after which they will be permanently retired:
Web Interface:
- Mainnet: etherscan.scrollscan.com
- Sepolia: sepolia-etherscan.scrollscan.com
Legacy API (Etherscan v2):
- Mainnet: https://api.etherscan.io/v2/api?chainid=534352&...
- Sepolia: https://api.etherscan.io/v2/api?chainid=534351&...
Action Required: Please update your dApp integrations and scripts to the new Blockscout APIs before the April 16th deadline to ensure uninterrupted service.
Thank you for your patience as we upgrade our infrastructure! 📜🚀
