Is there a blockchain app that you've been thinking of building? Need a hand getting started with blockchain development? Come hack on your favorite blockchain or crypto project with us every Thursday! Experts are on hand to help out and we keep each other accountable on each others' week to week progress.



Feel free to work on whatever platform or project you'd like.



From 12pm - 3pm join Crypto NYC and Token Foundry solidity developers, and learn how smart contracts work and the data payload required for all our blockchain startups to include when contributing to a token sale!



We will go over:

1. What is signing a transaction/data payload?

2. How to sign a transaction

3. How to verify the signature in a smart contract

4. Why this reduces gas



It would be helpful for participants to familiarize themselves with Remix (remix.ethereum.org) and install MetaMask (https://metamask.io/) prior to the meetup.



Bring your laptop!
