## Deployment

The contrct is already deployed to the ropstan test network using [infura](http://infura.io/), to redeploy you need to use the first account from the accounts generated by the seed phrase in truffle-config.json.



more information on how to deploy and intract with contracts on infura in this [guide](https://blog.infura.io/deploying-smart-contracts-managing-transactions-ethereum/).


- Deployed contract address: [ropstan](https://ropsten.etherscan.io/address/0x8f129e60fd0a99128b234ab2ad434178df78442d).

- Run `truffle migrate --network ropstan` to deploy to ropstan test network

## Web Interface development

There are 2 user interfaces, one for the customer and another for the admin/regulator,

which one is loaded depends on the account selected in metamask,

if its the first account in ganache then its the admin,

o add accounts from ganache to metamask follow [this guide](https://www.trufflesuite.com/docs/truffle/getting-started/truffle-with-metamask).

- Start the server using `npm run dev`

## Some Notes

- Referesh the page after changing account in metamask.

- `tailwind.config.js` enables tailwind IntelliSense in vscode with the [tailwind extension](https://marketplace.visualstudio.com/items?itemName=bradlc.vscode-tailwindcss).
