Solidity Metadata Uploader

Solidity Metadata Uploader uploads Solidity code metadata to swarm.

The metadata swarm hash is already added to end of your smart contract's byte code.

End user applications can then pull down this metadata from swarm and automatically generate a user interface for your dapp.

No more copy and pasting around ABI JSON! 🎉

Install

npm install --save-dev solidity-metadata-uploader

Usage with truffle

Add the following to your truffle migrations:

var MetaCoin = artifacts.require("./MetaCoin.sol");
var SolidityMetadataUploader = require("solidity-metadata-uploader");

module.exports = function(deployer) {
  deployer.deploy(MetaCoin);
  SolidityMetadataUploader.upload(`contracts/MetaCoin.sol`, (address) => {
    console.log(`Uploaded contract metadata to: http://swarm-gateways.net/bzzr:/${address}`);
  });
};
