TWISTER

There is already a popular protocol for depositing an amount and withdrawing it from another account, but unfortunately the deposit amounts are predefined. Would you like to be able to deposit any amount in increments of 0.001 eth and withdraw that amount in one or more transactions.

Noir with Vite and Hardhat

This example uses Vite as the frontend framework, and Hardhat to deploy and test.

Getting Started

Want to get started in a pinch? Start your project in a free Github Codespace!

In the meantime, follow these simple steps to work on your own machine:

1. Install yarn (tested on yarn v1.22.19)

2. Install Node.js >20.10 (latest LTS) (tested on v18.17.0)

3. Install noirup with

   curl -L https://raw.githubusercontent.com/noir-lang/noirup/main/install | bash

4. Install Nargo with

   noirup

5. Install dependencies with

   yarn

Generate verifier contract

Contract

The deployment assumes a verifier contract has been generated by nargo. In order to do this, run:

cd circuits
nargo codegen-verifier

A file named plonk_vk.sol should appear in the circuits/contracts/with_foundry folder.

Test locally

1. Copy vite-hardhat/.env.example to a new file vite-hardhat/.env.

2. Start a local development EVM at http://localhost:8545 with

   npx hardhat node

   or if foundry is preferred, with

   anvil

3. Run the example test file with

   yarn test

The test demonstrates basic usage of Noir in a TypeScript Node.js environment.

Deploy locally

1. Copy vite-hardhat/.env.example to a new file vite-hardhat/.env.

2. Start a local development EVM at http://localhost:8545 with

   npx hardhat node

   or if foundry is preferred, with

   anvil

3. Build the project and deploy contracts to the local development chain with

   NETWORK=localhost yarn build

   Note: If the deployment fails, try removing yarn.lock and reinstalling dependencies with yarn.

4. Once your contracts are deployed and the build is finished, you can preview the built website with

   yarn preview

Deploy on networks

You can choose any other network in hardhat.config.ts and deploy there using this NETWORK environment variable.

For example, NETWORK=mumbai yarn build or NETWORK=sepolia yarn build.

Make sure you:

• Update the deployer private keys in vite-hardhat/.env
• Have funds in the deployer account
• Add keys for alchemy (to act as a node) in vite-hardhat/.env

Feel free to contribute with other networks in hardhat.config.ts
