Ω Olympus Smart Contracts

This is the main Olympus smart contract development repository.

🔧 Setting up local development

Requirements

• Node.js 22+
• git

Local Setup Steps

# Clone the repository
git clone https://github.com/OlympusDAO/olympus-contracts.git

# Install dependencies
yarn install

# Set up environment variables (keys)
cp .env.example .env # (linux)
copy .env.example .env # (windows)

# compile solidity, the below will automatically also run yarn typechain
yarn compile

# if you want to explicitly run typechain, run
yarn compile --no-typechain
yarn typechain

# run a local hardhat node
yarn run start

# test deployment or deploy
# yarn run deploy:<network>, example:
yarn run deploy:hardhat

Local Setup Steps (with Docker)

A Docker image is available to simplify setup.

# First setup keys, to do this first copy as above
cp .env.example .env # (linux)
copy .env.example .env # (windows)

# Populate ALCHEMY_API_KEY and PRIVATE_KEY into `.env` afterwards
# Then, start the node
make run

📜 Contract Addresses

• For Ethereum Mainnet.
• For Rinkeby Testnet.

Notes for localhost

• The deployments/localhost directory is included in the git repository, so that the contract addresses remain constant. Otherwise, the frontend's constants.ts file would need to be updated.
• Avoid committing changes to the deployments/localhost files (unless you are sure), as this will alter the state of the hardhat node when deployed in tests.

📖 Guides

Contracts

• Allocator Contribution Guidelines
• Allocator Interaction Instructions
• Allocator version 1 guide (1.0.0).
• System Architecture (image)

Testing

• Hardhat testing guide
• Dapptools testing guide

Security Exceptions

Current unresolved findings are tracked inline in .trivyignore.

• @openzeppelin/[email protected] advisories are ignored for now because remediation requires migration to OpenZeppelin 4.x, which is currently out of scope.
• Remaining Docker image OS findings come from upstream node:22-bookworm-slim Debian packages. These should be revisited as upstream base-image patches are published.

Node Version Note

The repository currently targets Node.js 22 in CI and local tooling. This is a temporary compatibility measure while resolving Hardhat compiler-download failures observed under Node.js 24.
