Messenging app for peer-to-peer contract sharing
The problem ChronosProtocol solves
Chronos Protocol solves the trust problem in peer-to-peer agreements by combining secure wallet-to-wallet messaging with immutable smart contracts. Users can create binding agreements directly from chat conversations, with automatic execution when conditions are met.
It eliminates:
i. Middlemen and fees in contract creation
ii. The need to trust counterparties
iii. Technical barriers to blockchain use
iv. Security concerns with sensitive agreements
The platform allows anyone to create self-executing agreements with deadlines and value transfers using just their crypto wallet, bringing legally-binding smart contracts to everyday users without coding knowledge.
Challenges I ran into
Building Chronos Protocol presented several significant technical challenges:
Smart Contract Event Handling
The most complex issue was with our server-side contract event handling. We encountered a syntax error in our async arrow function for finding AgreementCreated events that broke the entire API. The function was missing proper curly braces, causing cascading failures across the application. We solved this by implementing a more robust event detection pattern with proper error handling and fallback mechanisms.
MetaMask Chain ID Formatting
Another critical bug occurred when users tried connecting to Base Sepolia. MetaMask rejected our chain ID with
Unrecognized chain ID "0x14a34"
errors. We discovered MetaMask expects zero-padded hexadecimal values. We implemented aformatChainIdHex
utility that properly formats chain IDs (converting 84532 to "0x014a34" instead of "0x14a34").XMTP Integration Challenges
Integrating wallet-to-wallet messaging required careful state management to avoid component re-rendering issues. We implemented custom hooks with useReducer for more predictable state transitions when handling message delivery confirmations.
The most valuable lesson was implementing comprehensive error boundaries and fallback mechanisms throughout the application, ensuring our dApp remains functional even when individual services fail.
