The Problem Voca.fi Solves
Complexity Barriers
Traditional DeFi interfaces can be intimidating and overwhelming, creating barriers to entry for new users and slowing down experienced traders during critical market moments.
Accessibility Challenges
Users with visual impairments, motor difficulties, or those uncomfortable with complex frontends face significant obstacles accessing DeFi markets.
Speed Constraints
Voice is often the fastest UI method. In fast-moving markets, navigating multiple screens and forms can mean missing optimal trading windows. Voice commands enable the quickest trade execution in time-sensitive environments.
Poor User Experience
Instead of conversing naturally about trading intentions, users must navigate complex DEX interfaces, manually compare routes, and execute multi-step transactions.
Core Capabilities
Voca.fi combines OpenAI's chat language models with real-time voice API to create a seamless multi-modal trading experience. Users can chat about their trading intentions, receive AI-powered market insights, and confirm trades via voice commands.
The AI assistant understands current market conditions and suggests optimal trading strategies, all while executing trades through simple voice confirmations.
Integration with Enso Finance enables intelligent routing that finds the best prices across decentralized exchanges while minimizing gas fees and slippage.
The AI assistant leverages Enso's routing capabilities to suggest optimal trading strategies, consolidating complex multi-hop swaps into single transactions for maximum efficiency.
Built on Safe's smart account infrastructure to provide secure, auditable transaction execution. Voice commands are translated into verified Safe transactions with built-in safety checks.
This creates novel infrastructure for human-agent-Safe communication, enabling voice-first interactions while maintaining enterprise-grade security standards.
Voice-first design removes barriers for users with visual impairments, motor difficulties, or those who find traditional DeFi interfaces overwhelming.
By combining chat assistance with voice commands, Voca.fi democratizes access to decentralized financeāmaking complex trading operations as simple as having a conversation.
Technical Innovation
Integrating OpenAI's real-time voice API on the client side presented unique challenges. To avoid building a complex backend and keep costs manageable for all users, we implemented a bring-your-own-keys (BYO) approach.
This allows users to leverage their own OpenAI API keys, ensuring privacy and cost control while maintaining the seamless multi-modal experience that combines chat language models with real-time voice processing.
Built on Next.js with TypeScript (98.7% type coverage), ensuring type-safe voice command processing, robust wallet interactions, and reliable state management.
Custom hooks manage swap quotes, token approval validation, balance tracking, router data retrieval, and transaction executionāall with compile-time safety guarantees.
Understanding Enso's routing and API structure was initially challenging, but once implemented, the SDK proved extremely easy to use and work with.
Enso's powerful routing capabilities enable optimal trade execution across multiple DEXs, consolidating complex operations into single transactions while maximizing value and minimizing gas costs.
Privy provides seamless authentication while Wagmi hooks enable secure wallet connections, transaction signing, and blockchain state management.
This combination ensures users can authenticate easily and execute trades securely, all while maintaining the speed and simplicity of voice-first interactions.
Real-World Impact
Beyond the Hackathon
Voca.fi demonstrates how voice technology can transform complex financial interfaces into accessible, intuitive experiences. The same principles powering this DeFi innovation are now being applied to practical business solutions through Cybergarden Software Development.
Whether it's voice-controlled trading platforms, AI receptionists, or conversational business tools, voice technology is reshaping how people interact with digital servicesāmaking them faster, more accessible, and genuinely user-friendly.
