Simplifying blockchain through conversations: GoPay enables anyone to send, receive, and manage cryptocurrencies with simple text messages, no technical knowledge or complex jargon required
The problem GoPay Wallet solves
The Problem GoPay Solves
GoPay addresses the fundamental challenge of blockchain adoption: accessibility. Despite cryptocurrency's growing popularity, most people find blockchain technology intimidating due to its technical complexity. Our solution removes these barriers:
1. Elimination of Technical Barriers
Users no longer need to understand wallets, private keys, gas fees, or blockchain addresses. GoPay handles these complexities behind the scenes, allowing anyone who can send a text message to use blockchain effectively.
2. Natural Conversation Instead of Complex Interfaces
Rather than navigating complicated wallet interfaces, users simply chat with our AI assistant:
- "Send $20 to [email protected]"
- "What's my balance?"
- "Show me my recent transactions"
3. Email-Based Identification vs Cryptic Addresses
Instead of dealing with long, error-prone hexadecimal addresses, users can send funds to email addresses. This dramatically reduces transaction errors and the anxiety of potentially losing funds.
4. Seamless Multi-Step Transactions
The system maintains conversation context, allowing for natural interactions:
- User: "I want to send some money"
- GoPay: "Sure, who would you like to send to?"
- User: "[email protected]"
- GoPay: "How much?"
- User: "50 dollars"
5. Security Without Complexity
GoPay maintains high security standards without burdening users with seed phrases or backup procedures.
By transforming blockchain interaction from a technical process to a conversational experience, GoPay opens cryptocurrency to the millions who would otherwise find it too complex to use.
Challenges we ran into
Challenges We Ran Into
Managing AI API Credits and Costs
Our most significant challenge was handling the limited AI API credits available for development. As we built and refined our conversational interface, we repeatedly reached our credit limits on OpenRouter, particularly during critical testing phases.
This constraint forced us to become resourceful. We developed a multi-pronged approach to maximize our available credits:
- We implemented selective API calling, where only complex queries would reach the external AI service
- We created a development environment with simulated responses for testing
- We carefully optimized our prompts to reduce token usage without sacrificing quality
- We prioritized certain features for AI testing, while using rule-based systems for others
This experience taught us valuable lessons about building AI applications within real-world constraints. We gained expertise in prompt engineering and learned to balance capability with cost efficiency - skills that will help us scale the product sustainably.
Balancing Technical Complexity and User Simplicity
Another significant challenge was maintaining the technical robustness required for blockchain operations while keeping the user experience conversational and approachable.
When a user types "send $20 to John," multiple complex operations happen behind the scenes - email resolution, balance checking, transaction preparation, gas estimation, and blockchain interaction - yet the user should see only a simple, human response.
Structuring our system to handle this complexity while maintaining a conversational flow required careful architecture and considerable testing, especially for multi-step transactions where context needed to be preserved between messages.
Through solving these challenges, we've created a system that hides extraordinary complexity behind a simple chat interface - precisely what's needed to bring blockchain to mainstream users.
