Pasacoin

Pasacoin is a DeFi platform that transforms traditional collective savings into a digital, secure, and frictionless experience. Inspired by ancestral methods—such as the pasanaco in Bolivia, the vaquita in Argentina, or the rosca in other regions—Pasacoin leverages blockchain technology to ensure every transaction is immutable and transparent. At the heart of the project is its intelligent agent integrated via WhatsApp, which empowers any user, regardless of technical expertise, to access advanced financial tools. The agent performs multiple functions: it retrieves the current USDT price and converts it to the local currency (using, for example, the parallel dollar rate in Bolivia), automatically generates QR codes for seamless payments, and directly interacts with smart contracts to execute transactions. Additionally, the agent monitors all operations in real time, detects suspicious activities, and triggers security measures to protect community funds. By merging traditional savings methods with state-of-the-art technology, Pasacoin democratizes access to secure, transparent, and efficient financial services for communities worldwide.

Pasacoin was developed by integrating cutting-edge technologies to build a scalable and secure architecture:

Blockchain & Smart Contracts: Smart contracts written in Solidity on the Ethereum network record every transaction immutably and transparently.

State Channels: Implementing state channels enables nearly instantaneous off-chain transactions, reducing both costs and waiting times.

Intelligent WhatsApp Agent: The core of the system is an intelligent agent built with AI algorithms. Integrated with the WhatsApp Business API, the agent:

Queries the real-time USDT price and converts it to the local currency (e.g., factoring in Bolivia’s parallel dollar rate). Automatically generates QR codes for easy payment processing. Interacts directly with smart contracts to execute and verify transactions securely without manual intervention. Frontend & Backend: The user interface is developed in React, providing an intuitive and accessible experience. Meanwhile, the backend, built with Node.js and Express, manages communications between the interface, the intelligent agent, the blockchain, and external exchange APIs.

Decentralized Storage: IPFS is used for decentralized storage of digital assets and data, ensuring data integrity and availability.

Showcased at the EHT Agents Hackathon, this integrated architecture demonstrates how the fusion of digital innovation and traditional financial practices can transform access to financial services—delivering a robust, transparent tool that anyone can use right from their everyday WhatsApp.
