EVM Prediction Market Contracts

A comprehensive collection of smart contracts for building prediction market platforms compatible with EVM chains, including BASE.

---

Overview

This repository provides a suite of smart contracts supporting prediction markets on EVM-compatible blockchains. It includes tools for deployment, testing, and network management, enabling developers to efficiently build and maintain prediction market applications.

---

Installation

Install requirements with npm:

npm install @gnosis.pm/pm-contracts

---

Testing and Linting

Run all tests (requires Node version >=7 for async/await; TestRPC runs automatically):

npm test

Run tests matching a pattern:

TEST_GREP='your-pattern' npm test

Lint the JavaScript code:

npm run lint

---

Compile and Deploy

Ensure your RPC provider (e.g., TestRPC or a local node) is running on port 8545.

Compile all contracts to generate ABI and bytecode:

npm run compile

Migrate contracts to your network:

npm run migrate

Note: These commands are wrappers around Truffle commands. You can pass additional options via --.

---

Network Management

Show deployed contract addresses on all networks:

npm run networks

Clean network artifacts:

npm run networks -- --clean

Inject network info from networks.json into build artifacts:

npm run injectnetinfo

Extract network info to networks.json (overwrites existing):

npm run extractnetinfo

---

Gas Usage Measurements

Log gas statistics for your contracts:

npm run measuregasstats

Results are stored in build/gas-stats.json.
