It’s designed to empower users with autonomy, operational intelligence, and a truly customizable financial infrastructure.

Key Features

Midaz isn’t just another financial tool; it’s a comprehensive ecosystem built on a foundation of powerful features designed for the modern financial landscape. Here’s what makes it stand out:

• Open-source financial ledger: Released under Apache 2.0 license, providing transparency and allowing for community-driven development and auditing, fostering trust and adaptability across the financial sector.
• Modular plugin architecture: Enables users to extend and customize the system’s functionality with ease, tailoring it to specific business needs without rigid constraints through a marketplace of community-built plugins.
• AI-powered Model Context Protocol (MCP): Integrates seamlessly with AI assistants like Claude and ChatGPT through dedicated MCP servers, enabling intelligent transaction analysis and automated financial operations.
• Advanced AI integration: Leverages Model Context Protocol to enhance transaction insights, automate processes, and support intelligent decision-making with real-time AI assistance.
• Operational intelligence tools: Equips users with powerful analytics and insights to monitor performance, identify trends, and optimize financial operations through comprehensive reporting and monitoring.
• Latin America-focused design: Specifically tailored to meet the unique regulatory, operational, and market demands of the Latin American financial sector while maintaining global compatibility.

How It Works

Understanding the mechanics behind Midaz reveals its innovative approach to financial management. The platform operates on a cloud-native, microservices architecture that puts control directly into the hands of its users. Here’s a look at its operational flow:

Users begin by deploying Midaz as an open-source financial system, which serves as the core ledger built on Go with PostgreSQL and MongoDB databases. This foundational setup is then enhanced through its modular plugin architecture, allowing for seamless integration of custom functionalities and extensions. The system uses RabbitMQ for event-driven processing, efficiently coordinating data flow across various financial channels. What truly sets Midaz apart is its Model Context Protocol (MCP) integration, which enables AI assistants to interact directly with the ledger system, significantly enhancing transaction tracking and supporting more informed decision-making. This design ensures high levels of autonomy and interoperability, making Midaz a versatile solution for diverse financial environments.

Use Cases

The versatility of Lerian Midaz makes it an ideal solution for a variety of financial challenges and innovative projects. Its unique combination of open-source flexibility and AI-powered intelligence opens doors for numerous applications:

• Digital banking platforms: Create full-featured digital banks with accounts, payments, and comprehensive financial products using Midaz as the foundational ledger system.
• Payment processing systems: Build robust payment infrastructure with multi-currency support, handling high-volume transactions with real-time processing capabilities.
• Asset management platforms: Manage complex portfolios across multiple asset classes with sophisticated balance tracking and audit trails.
• Treasury management systems: Create sophisticated cash management and forecasting tools with real-time liquidity monitoring and automated reconciliation.
• Blockchain and crypto integration: Bridge traditional finance and digital assets in a unified system with multi-asset support and immutable transaction records.
• Financial inclusion solutions: Develop accessible financial services for underserved markets with customizable workflows and compliance features.

Pros \& Cons

Like any powerful tool, Midaz comes with its own set of strengths and considerations. Understanding these can help you determine if it’s the right fit for your organization.

Advantages

• Open-source transparency: Released under Apache 2.0 license, fostering trust, allowing for community contributions, and providing full visibility into system operations without vendor lock-in.
• Highly modular architecture: Offers unparalleled flexibility through microservices design, enabling users to customize and extend functionality to precisely match their unique requirements.
• AI-enhanced processing: Leverages Model Context Protocol for intelligent transaction analysis, automated compliance checking, and enhanced operational intelligence through AI assistant integration.
• Proven track record: Successfully implemented by established financial institutions including Banco Boreal, demonstrating production-ready reliability and scalability.
• Strong community support: Active Discord community and comprehensive documentation provide extensive support for developers and operators.

Disadvantages

• Technical expertise requirement: As an open-source system, initial setup and customization require significant technical proficiency and development resources.
• Limited global market presence: While powerful regionally, its focus on Latin America means it may not yet have the widespread recognition of established global competitors.
• Early ecosystem stage: Though growing rapidly, the community and third-party integrations are still developing compared to more established platforms like Hyperledger or traditional core banking systems.

How Does It Compare?

In the competitive landscape of financial ledgers and open-source banking solutions, Lerian Midaz positions itself uniquely against both established and emerging players in 2024-2025.

Formance recently raised \$21 million in Series A funding (January 2025) and offers a programmable ledger with multi-module platform approach. While Formance focuses on European and global markets, Midaz distinguishes itself with deeper Latin American regulatory compliance and native AI integration through MCP protocols.

Blnk Finance provides an open-source ledger with strong developer tools and reconciliation features. However, Midaz offers superior AI capabilities and more comprehensive plugin architecture, making it particularly appealing for organizations seeking advanced automation and intelligence.

TigerBeetle, which raised \$24 million in July 2024, excels in raw transaction performance with specialized database architecture. Midaz trades some performance for greater flexibility and AI integration, targeting organizations that prioritize customization and intelligent operations over pure speed.

Hyperledger Fabric remains the established enterprise blockchain platform with extensive enterprise adoption. Midaz differentiates through its financial-specific design, AI-native architecture, and significantly simpler deployment process, making it more accessible for fintech startups and mid-market banks.

Traditional core banking systems like Temenos and Mambu offer comprehensive features but with significant vendor lock-in and licensing costs. Midaz provides a truly open alternative with comparable functionality at a fraction of the cost, while enabling complete customization and control.

Final Thoughts

Lerian Midaz represents a significant leap forward for financial technology, not just in Latin America but globally. By combining the transparency and flexibility of open-source development with cutting-edge AI integration through Model Context Protocol, it offers a compelling solution for complex financial operations. The platform’s successful implementation at institutions like Banco Boreal and recognition in BTG Pactual’s Boostlab program demonstrate its production readiness and market validation.

While it continues building its global presence and ecosystem, Midaz’s regional expertise, commitment to modularity, and AI-native design make it a powerful contender for businesses ready to embrace the future of finance with complete autonomy and intelligence. As the open-source financial infrastructure movement gains momentum, Midaz is well-positioned to become a cornerstone technology for the next generation of financial services.
