EVM-Prediction-Market-Backend
EVM Prediction Market Backend Node.js TypeScript service for a prediction market on EVM chains: JSON-RPC reads/writes, REST API for a web UI, PostgreSQL via Prisma, an off-chain central limit order book (CLOB) with optional EIP-712 signed orders, and Socket.IO for live order book and trade updates. This repository is a backend template. You must align the Solidity ABI (src/contracts/prediction-market.abi.ts) and environment variables with your deployed contracts. Architecture - Chain layer (src/services/blockchain/): ethers v6 JsonRpcProvider, read-only + optional operator wallet, calldata encoding for wallet-driven txs (/api/v1/tx/), and a lightweight log listener that upserts Market rows and stores raw logs in ChainEvent. - Order book (src/services/orderbook/): in-memory price–time priority matching per (marketId, outcomeIndex); PostgreSQL persists orders and trades. Suitable for a single API instance or a leader writer; for horizontal scale, add Redis or move matching behind a dedicated worker. - UI integration: CORS-enabled REST + GET /api/v1/config/eip712 for typed-data signing;
