What is this repository?

This repository documents blockchain service providers (RPCs, wallets, explorers, analytics, bridges, etc.) in a structured way. The goal is to build a clean, comparable dataset that developers and researchers can rely on.

Each service type has its own table with predefined columns. Contributors should follow the rules for each table to keep the data consistent and accurate.

The repository follows this model:

provider -> offer -> listing

• references/providers/providers.csv stores provider identity and metadata.
• references/offers/<category>.csv stores canonical offers.
• listings/specific-networks/<network>/<category>.csv stores network-specific listings.
• listings/all-networks/<category>.csv stores listings propagated to all networks.

How to Contribute

1. Pick the correct category CSV (for example APIs, Wallets, Bridges, MCP Servers).
2. Read the Style Guide for general guidelines.
3. Read that table’s page for column definitions.
4. Fill rows according to the rules.
5. Submit a PR.
