# QRL Developer Resources

> Official documentation, APIs, source code, and protocol resources for developers building with The Quantum Resistant Ledger (QRL).

For the complete agent-oriented site index, see [llms.txt](/llms.txt).


## QRL 2.0 development

QRL 2.0 is the project's quantum-resistant, EVM-derived network. Start with the [QRL 2.0 Testnet V2 documentation](https://test-zond.theqrl.org/testnet) for network access, node operation, and smart-contract development.

## Original QRL network

The [QRL documentation](https://docs.theqrl.org/) covers nodes, wallets, mining, the command-line interface, and integrations for the original QRL network. Its [node API reference](https://api.theqrl.org/) documents the APIs exposed by that network.

## Machine-readable API discovery

The [QRL OpenAPI specification](/openapi.json) describes the public, read-only developer-resource catalog hosted on this website:

- [API index](/api)
- [Versioned developer-resource catalog](/api/v1/resources)

The website catalog requires no authentication. It points clients to QRL documentation and source material; it is not a blockchain node or wallet API.

## Source code and protocol proposals

- [QRL on GitHub](https://github.com/theQRL): official protocol, cryptography, wallet, tooling, and website repositories.
- [QRL Improvement Proposals](/roadmap/#qips): protocol proposals and their current statuses.
- [Security reporting](/security-report/): responsible-disclosure instructions and security contact details.

## Webhooks and MCP

This directory does not currently advertise an official QRL webhook product or MCP server. Use the documentation and repository links above for supported integration surfaces.
