Pokemon ERC-721

ERC-721 is the Ethereum standard for non-fungible tokens.

Full working sample

This project is composed by two components:

• Truffle project
• App - repository

The Truffle project contains the smart contracts and all the tools for the contracts deployment and testing.

The App project contains a simple server to retrive the Pokemon tokenURI information and a HTML page to display and transfer the tokens and so the related Pokemons.

To quickly run the whole project

• clone this repository
• $ npm i
• $ cd config && cp config.js.sample config.js
• use the following as config.js:

module.exports = {
  pokemon: {
    min: 1,
    max: 151,
    extraMax: 201,
    uriUrl: 'http://localhost:3000/api/pokemons',
  },
  networks: {
    parity: {
      receiver: 'SOMETHING',
    },
  },
} 

• $ npm run ganache | Save the private keys of the displayed accounts, you will need to import it into Metamask
• $ npm run migrate:development

At this point leaving all up and running move to the Pokemon App README and follow the instructions.

System used

System used during the development of the project

• node v10.9.0
• npm 6.2.0

Install

Install project dependencies

Command: $ npm i

Available networks

Truffle newtowks

• development
• parity (usage needs to be granted)

Run local Ethereum node

As it's configured the following script spawn a local Ethereum Network with the following params:

• port: 7545
• networkId: 47
• blockTime: 1 sec

Command: $ npm run ganache

Truffle migration

Deploy and mint each unique token to the specified network

NOTE: for the contracts deployment will be used the eth.accounts[0] on both network (it needs to be unlock and funded)

NOTE: at t0 all the tokens will be minted towards eth.accounts[1] in the development network

NOTE: at t0 all the tokens will be minted towards config specified account in the parity network

Command: $ npm run migrate:NETWORK_NAME

Run the tests

Truffle smart contract tests

Command: $ npm run test:NETWORK_NAME

Mint Pokemon on demand

NOTE: will mint towards eth.accounts[1] in the development network

NOTE: will mint towards config specified account in the parity network

Command: $ npm run mint:NETWORK_NAME

Config

The config folder contains a config file where you can specified for the parity network the receiver address of the minted tokens.

In addition you can specify the range of avaiable pokemons you want to mint. Keep in mind that the related App project supports only the first 151 pokemon.
