Please note that the video provided here was recorded on rinkeby test network, since we were facing issues connecting to bttc test network, and we were running late for submissions on devpost.
The contract was intented to be deployed on bttc network, as well as tron network which supported energy free transactions with locked trx.
We will be uploading complete features video, with bttc deployment as well as tron deployment link soon.
We will also be updating a lot of UI as soon as possible.
