A secure and user-friendly system for distributing testnet tokens to developers using Cosmos SDK.

Project Description

The Cosmos Faucet is a sophisticated platform designed to facilitate the distribution of testnet tokens to developers working on the Cosmos SDK. This project is essential for developers who need to test their smart contracts and decentralized applications. With a focus on security and user experience, the platform provides a robust framework for requesting tokens while preventing spam and ensuring fair distribution. It supports multiple wallet types, offers real-time monitoring and analytics, and includes an admin dashboard for efficient management. By streamlining token distribution, the Cosmos Faucet significantly aids developers in their testing and development processes.

Scope of Work

The client's original goals were to create a secure Cosmos testnet faucet that enables developers to request tokens using verified wallets, while ensuring rate-limited distribution to prevent misuse. The project needed user-friendly admin tools for monitoring the platform’s usage, managing the faucet infrastructure, and distributing tokens fairly. The challenge was to ensure a spam-free environment that supports reliable token requests, while providing analytics and support for multiple wallet types. This required a system capable of managing high-volume token requests efficiently and securely.

Our Solution

Crazi Co delivered a comprehensive Cosmos faucet system with various advanced features to address the client’s needs. The solution included wallet validation for Cosmos-based addresses to ensure they are valid and secure. A key component was the token distribution logic that implemented strict rate limits per IP and wallet, preventing abuse and ensuring equitable access. An admin dashboard was developed to provide complete oversight of faucet activities, allowing the monitoring of usage, token reserves, and detailed distribution logs. Additionally, a queue and retry system was established to manage large token requests efficiently, and reCAPTCHA was integrated to ensure human verification, blocking bots effectively.

Key Features

• Wallet Validation: Supports Cosmos-based wallet addresses with checksum validation to ensure secure and valid token requests.

• Token Distribution Logic: Incorporates rate limits on token requests per IP and wallet to prevent abuse and ensure fair access for all developers.

• Admin Dashboard: Equipped with tools to monitor faucet usage, manage token reserves, and review detailed distribution logs, the dashboard empowers efficient management.

• Queue and Retry System: Manages high-volume token requests with queued processing and retry mechanisms ensuring no request is lost.

• Captcha Protection: Utilizes reCAPTCHA for bot protection, ensuring each request is made by a human, thereby maintaining integrity and security.
