demo-erc721

Using Democracy to access ERC-721 assets.

This demo retrieves the owner of an NFT by Token ID programmatically using the ERC-721 ABI.

We call the ownerOf method, but any of the methods are available here:

http://erc721.org/

Prerequisites

I use Node v11.14.0 (earlier may also work) managed by nvm

How to use

Clone this repo locally

git clone https://github.com/cryptogoth/demo-erc721.git

Install dependencies with yarn or npm install

yarn

Create a secure, web-accessible Ethereum account by going to http://ethgarden.com and copying and pasting them into your .env file.

This wallet doesn't need any ETH so far and isn't used to hold any assets. You'll fund it later and use it if you need to call contract mutator methods that change on-chain state.

For this demo, we only call read-only methods.

Edit these lines in the .env file

MAINNET.DEPLOYER_ADDRESS=''
MAINNET.DEPLOYER_PASSWORD=''

Do the thing

yarn depart

Wait a few seconds, and you'll see some output (the owner of an ERC721 NFT on mainnet)

NFT Owner is {"0":"0x66040374e443ae3e25afef08a781c4c2d175f43c"}

You can verify this with the NFT on Etherscan:
