Accord365 (Gin + Blockchain)

Accord365 is an Ethereum-based banking application built using the Go Gin framework and modern web technologies. The project explored blockchain integrations, user account management, and real-world transaction workflows.

Although development was not fully completed, this repo documents significant progress toward building a decentralized banking app that combines blockchain with a traditional backend.

Features & Accomplishments

- Go/Gin Server

• Built server with HTML templates and dynamic routes.
• Implemented cookies and session management.

- Authentication & Security

• Integrated OAuth2 for Google in Gin framework.
• Validated JavaScript forms using regular expressions.

- Database Layer

• Designed and updated Postgres and MySQL schemas.
• Created database models and implemented Create & Update queries.

- Blockchain & Web3 Integration

• Developed an ERC-20 token buying page using Solidity, JSON, and JavaScript.
• Connected with Web3.js API for contract and transaction calls.
• Implemented wallet functionality for users to load Ether.
• Used JavaScript Promises to complete web3 transactions.

- Testing & Tools

• Conducted blockchain testing with Ganache, Metamask, Geth, Rinkeby, and Ropsten testnets.
• Used Truffle-Contracts to interact with smart contracts.

- Front-End Work

• Built pages with JavaScript, jQuery, HTML, CSS, and Bootstrap.
• Prototyped wireframes and collaborated with the client in focus groups.
• Experimented with the Buffalo framework (Go front end).

Tech Stack

Getting Started

This project was developed using Go Gin, Postgres/MySQL, and Web3.js.
To explore the code:

1. Clone the repository
2. Review the /models, /routes, and /blockchain directories
3. See main.go for the application entry point

⚠️ Note: This project is not currently maintained as a runnable app,
but the codebase provides a solid reference for blockchain integration in Gin.

Project Notes

This repo represents my work during the development phase of Accord365. While I was not able to complete every feature, the following milestones were achieved:

• Successful integration of blockchain interactions into a Go/Gin web app.
• End-to-end testing of token transactions in Ethereum testnets.
• Client meetings, documentation, and planning to support the next developer.

Collaboration

• Partnered with teammates on JavaScript and Go development challenges.
• Reached out for peer support on routing problems.
• Led debriefs with the client to ensure transparency and alignment.

Lessons Learned

Working on Accord365 gave me hands-on experience with:

• Designing for both traditional databases and blockchain systems in the same application
• Implementing authentication flows in a new backend framework (Gin)
• Balancing client requirements with technical feasibility through prototyping and iteration
• The importance of clear project organization, which I improved by documenting plans and creating a mobile to-do tracker

Future Development

If continued, the next developer could expand this foundation by:

• Finalizing the Gin routing logic and improving scalability.
• Enhancing the wallet system for production readiness.
• Migrating front-end components to a modern framework for a smoother UX.
• Strengthening error handling and transaction security in blockchain interactions.
