How do I get my free PyCon India 2019 ticket?
We want you to create a python application that creatively uses the EthVigil API by end of September 29th, 2019 (IST). It could be any idea that utilizes the blockchain in a useful and/or a fun way. If you feel stuck, feel free to build on the following idea. Jump to quick references, read the rules or check the full docs.
CryptoZombies Game Tutorial
We will recreate the first two chapters of the Cryptozombies game tutorial that runs on blockchain on EthVigil, our API gateway for the Ethereum blockchain.
But I know nothing about blockchain!
Worry not. You will be using our APIs for Ethereum that abstracts away primitives like transaction, transaction fees(gas costs), ABI, monitoring contract events etc.
- you will be making GET/POST calls over HTTPS to automatically generated REST API endpoints.
- set up webhook endpoints to which EthVigil will push real time event data from the smart contract
Cool. How do I get started?
We have slightly modified the source code of the main 'zombie feeding' contract to fetch 'kitty' data from a contract instance that is on the Ethereum Görli testnet, not the mainnet.
Mainnet transactions cost real Ether monies.
Zombie feeding contract
Dummy cryptokitty contract
0x6feBb2A3E3AeD1691Aba98350ee6CF447E1AF9B8 in the code above is an instance of a dummy contract deployed on the Görli testnet that emulates the interface of the main CryptoKitties contract by supplying a
getKitty() method implementation.
This is just a placeholder contract. Feel free to make it as complex and detailed as you wish to support more 'character traits'. We suggest reading through The Oatmeal's guide on cats: How much does your cat actually kill
Quick references to get started
Deploying a contract
Adding webhook integrations
We would strongly suggest going through any of the following walkthroughs we have published to get comfortable with reading from and writing to a smart contract via the API gateway as well as connecting off-chain logic through webhook integrations.
