MAS Market

MAS Market is a real-time agentic prediction market platform where specialized AI agents work together to analyze events and make intelligent predictions. The platform leverages a multi-agent architecture powered by the A2A (Agent-to-Agent) protocol, with a host orchestrator coordinating three specialized agents: a Research Agent that analyzes markets using advanced technical indicators (RSI, MACD, Bollinger Bands), real-time crypto price data, and news sentiment; a Polymarket Agent that fetches live market data and executes trades with real-time CLOB pricing; and a Bettor Agent that handles blockchain transactions and payouts using the x402 payment protocol on Hedera testnet.

Backend Technical Architecture

System Overview

MAS Market uses a multi-agent architecture with A2A (Agent-to-Agent) protocol for distributed intelligence. The system consists of a host orchestrator (A2A Client) coordinating three specialized A2A Servers, each running on independent ports.

Architecture Components

1. Host Agent (A2A Client) Role: Central orchestrator that receives user requests and delegates to specialized agents

Communication: Uses A2A SDK to communicate with remote agents via HTTP Flow:

Receives user query from frontend Determines which agent(s) to invoke based on task Sends requests to appropriate A2A servers Aggregates responses and returns to frontend

1. Research Agent (A2A Server)

Role: Market analysis and prediction generation

Technology Stack: LangChain v1 for agent creation Google Gemini 2.5 Flash LLM A2A SDK server implementation

Tools:

internet_search - Tavily API for news and events get_crypto_price_data - CoinGecko API for real-time prices

Input: Event ID or market question

Output: JSON with summary, market_type, what_to_bet, confidence, technical_signals, data_sources

Response Types: Binary markets: "yes" | "no" | "insufficient_data" Continuous markets: numerical price target

1. Polymarket Agent (A2A Server)

Role: Market data fetching and trade execution

Technology Stack: LangChain v1 agent A2A SDK server Polymarket Series API

Tools:

Market data retrieval from Polymarket API

Input: User preferences and event data from Host Agent

Output: Available markets, prices, and trade confirmation

1. Bettor Agent (A2A Server)

Role: Blockchain transaction execution and settlement

Technology Stack:

LangChain v1 agent Hedera SDK for blockchain interaction x402 payment protocol integration A2A SDK server

Tools:

trigger_x402_payment - Initiate blockchain payment record_bet - Store bet on-chain check_market_resolution - Verify market outcomes get_winning_bets - Query winning positions trigger_payout - Execute winner payouts

Input: Payment intent from Host Agent

Output: Transaction hash and settlement confirmation

Blockchain: Hedera testnet with HCS (Hedera Consensus Service)
