SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires ethers, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill enables the creation of an on-chain content indexer for Ethscriptions on Base, reducing costs and increasing decentralization of data indexing.

Core Features & Use Cases

  • Content Indexing: Tracks and indexes inscribed content hashes and ownership transfers on the Base L2.
  • Historical Backfill: Supports syncing from genesis to latest, ensuring comprehensive data coverage.
  • APIs for Data Access: Provides REST endpoints for existence checks, detailed retrieval, owned content, and statistics.
  • Use Case: For dApp developers or content platforms to reliably verify and retrieve user-inscribed content across the Base network without direct Ethereum mainnet costs.

Quick Start

Use the script to run the indexer from genesis or a specific block range, then query the APIs for content or ownership info.

Frequently Asked Questions about Skill: Ethereum Ethscriptions Indexer for Base

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I index Ethscriptions content on Base L2?▼

To index Ethscriptions content on Base L2, run the provided script to process batched blocks from genesis, tracking inscribed content hashes and ownership transfers while storing records in PostgreSQL via Supabase.

What is on-chain content indexing for Base Ethscriptions used for?▼

On-chain content indexing for Base Ethscriptions enables scalable, decentralized content discovery and verification, allowing dApp developers to reliably retrieve user-inscribed data without incurring Ethereum mainnet costs.

Does this Base Ethscriptions indexer support historical data backfill?▼

Yes, the Base Ethscriptions indexer supports historical data backfill by syncing from genesis to the latest block, ensuring comprehensive data coverage for inscribed content hashes and ownership transfers.

Can I use ethers.js with Supabase to build a blockchain indexer?▼

Yes, you can use ethers.js with Supabase to build a blockchain indexer, as this configuration uses ethers.js for Base L2 interaction and PostgreSQL via Supabase for scalable database storage and REST API access.

How do I verify inscribed content ownership using a REST API?▼

You can verify inscribed content ownership using the provided REST endpoints, which support existence checks, detailed content retrieval, owned content queries, and indexer statistics for the Base network.

What's the best way to retrieve inscribed content hashes without Ethereum mainnet costs?▼

The best way to retrieve inscribed content hashes without Ethereum mainnet costs is using a Base L2 indexer that tracks inscriptions and provides REST APIs for decentralized, low-cost content verification and access.
