UFarm EVM Contracts

UFarm Digital — Efficient digital asset management for everyone.

This repository contains the smart contracts of UFarm Digital Protocol.

Development

Hardhat is used for smart-contracts development, testing and deploying.

Prerequisites

• NodeJS v20.9.0 or newer

Installation

git submodule update --init --recursive
npm install

Compilation

To compile smart-contracts and typechain types use the command:

npm run compile

It places aftifacts into the directories according to the template:

artifacts/contracts/<ContractName>.sol/

and typescript types into the directory:

typechain-types/

Testing

Tests are launched by the command:

npm test

Launching a node for the DApp

As the first step the ethereum node should be launched by the command:

npm run start-no-deploy

It prints the URL of the JSON-RPC server, which might be used by the DApp.

Now in the second terminal the command deploying the contracts should be run:

npm run deploy-local-all

It deploys contracts into the local blockchain. Since that moment the DApp is able to use JSON-RPC API.
