AstraDeFi Smart Contracts

This repository contains the Solidity smart contracts and subgraph configurations for the AstraDeFi platform. The contracts cover a wide range of DeFi functionalities, including staking, rewards, liquidity provision, automated market makers (AMM), and more. These contracts are deployed across multiple test networks to ensure broad coverage and scalability.

📜 Contracts Overview

The following key contracts are deployed across various networks:

• Staking Token Contract: Users can stake their tokens in this contract to participate in the platform.
• Reward Token Contract: Provides rewards to users who participate in staking or liquidity provision.
• Staking Contract: Manages staking, rewards, and other related functionalities.
• AMM Contract: Automated market maker contract for facilitating decentralized trading and liquidity.
• Faucet Contract: Provides tokens for testing purposes on supported networks.

Supported Networks & Chain IDs

• ETH Sepolia Testnet (11155111)
• ETH Holesky Testnet (17000)
• Optimism Sepolia Testnet (11155420)
• Mode Testnet (919)
• Base Sepolia Testnet (84532)
• Polygon Amoy Testnet (80002)

Each network has its own set of contract addresses and subgraph URLs for data querying.

📦 Development Setup

To get started with the development of the smart contracts and The Graph subgraphs:

Step 1: Clone the Repository

git clone https://github.com/your-username/astradefi-contracts.git
cd astradefi-contracts

Step 2: Set Up Environment Variables

Step 3: Compile Contracts

Compile the smart contracts using Hardhat:

npx hardhat compile

Step 4: Deploy Contracts

To deploy the contracts to a specific network:

npx hardhat run scripts/deploy.js --network <network-name>

Replace with the target network (e.g., ethSepolia, polygonAmoyTestnet, etc.).

Step 5: Verify Contracts

To verify the contracts on the blockchain explorers:

npx hardhat verify --network <network-name> <contract-address>

Step 6: Build & Deploy Subgraphs

To deploy the subgraph for querying contract data:

graph build
graph deploy --product hosted-service <your-subgraph-name>

Step 7: Testing

To run tests:

npx hardhat test
