The Wan Smart Contract

This very simple smart contract is used to store a single IPFS file hash that can be retrieved by calling the contract.

My deployed contract address (Wanchain Testnet) is 0x4Ef0e1c84c937bc1cE35f9b63047881E41fa1076

Contract Code

//deployed using remix

contract Contract {
 string ipfsHash;

 function sendHash(string x) public {
   ipfsHash = x;
 }

 function getHash() public view returns (string x) {
   return ipfsHash;
 }
}

1. Deploy Your Smart Contract using Remix

Once you deploy your smart contract you will receive a contract address.

In storehash.js on line 5 update the contract address to your new contract address.

If you made any edits to the contract, you will also need to update the contract ABI inside storehash.js
