Setup Local Environment

Setup HTTPS for Local Wallet Pairing

The Hedera DeFi Accelerator apps utilize the hashconnect library to pair with supported wallet extensions. Currently, the only supported wallet extension is HashPack. The HashConnect 1-click pairing feature only works in an SSL secured environment (https URLs). To enable HTTPS in your local build:

1. Create an .env file in the root of this project.
2. In the .env file set the HTTPS environment variable to true.

/* .env */
HTTPS=true

3. Create an SSL certificate. There are several tools that can be used to generate a certificate and key. An easy way to do this is to use the mkcert tool.

# The [Homebrew](https://brew.sh/) macOS package manager is used for this example

# Install mkcert tool
brew install mkcert

# Install nss (only needed if you use Firefox)
brew install nss

# Setup mkcert on your machine (creates a CA)
mkcert -install

# Create a directory to store the certificate and key
mkdir -p .cert

# Generate the certificate (ran from the root of this project)
mkcert -key-file ./.cert/key.pem -cert-file ./.cert/cert.pem "localhost"

4. Set the SSL_CRT_FILE and SSL_CRT_FILE environment variables to the path of the certificate and key files.

/* .env */
HTTPS=true

/* Path to certificate */
SSL_CRT_FILE=./.cert/cert.pem

/* Path to key */
SSL_KEY_FILE=./.cert/key.pem

5. Make sure to include .env and .cert in your .gitignore file so this information is not committed to version control.

6. Run the application with vercel dev (see Usage for Vercel installation). You should see https:// prefixed to the localhost URL.

Setup Pinata Environment variables to use the Pinata IPFS API

The DeFi apps store and retrieve IPFS data using Pinata. A Pinata public key, secret key, and gateway URL are necessary for IPFS pinning and fetching features to work as intended. You will need to create a Pinata account to create a new set of keys and a gateway URL. A more comprehensive tutorial can be found in the Pinata API Docs.

PRIVATE_PINATA_API_KEY=/** Public Key **/
PRIVATE_PINATA_API_SECRET_KEY=/** Secret Key **/
VITE_PUBLIC_PINATA_GATEWAY_URL=/** Gateway URL **/

Usage

The DeFi apps utilize Vercel Serverless Functions to communicate with third-party APIs such as IPFS. You will need to install the Vercel CLI to run the applications.

Run The Application

vercel dev
