Zap by Paycrest is a dApp developed for the [Onchain Summer Buildathon](https://onchain-summer.devfolio.co/). Our goal is to simplify the conversion of cryptocurrency to local currency by leveraging a decentralized liquidity protocol, we aim to provide a seamless and efficient user experience.

Check out our live demo at [zap.paycrest.io](https://zap.paycrest.io).

## 🚀 Running Locally

To run Zap locally, follow these steps:

```bash

git clone https://github.com/paycrest/zap.git

cd zap

npm install

npm run dev

```

Don't forget to fill in the necessary variables in the `.env.local` file according to the template provided in [`.env.example`](.env.example).

Then, visit [http://localhost:3000](http://localhost:3000) to start converting crypto to fiat.

## 📚 How It Works

Zap streamlines the conversion process through a simple flow:

1. **Create Order:** User creates an order on the [Gateway Smart Contract](https://github.com/paycrest/contracts) (escrow) through the Zap interface.

2. **Aggregate:** Paycrest Protocol Aggregator indexes the order and assigns it to one or more [Provision Nodes](https://github.com/paycrest/provider) run by liquidity providers.

3. **Fulfill:** The provisioning node automatically disburses funds to the recipient's local bank account or mobile money wallet via connections to payment service providers (PSP).
