Ethereum Contract Creation
Step by Step
Ujwal Tamminedi
Date – 30-03-2019
• To take forward the process of showing my
understanding of crypto currency and blockchain, I took
up the task of creating my own ICO on Ethereum (I have
called the token – UJI and the name of the ICO – UJWAL
Token)
• Ethereum Wallet – MyEtherWallet
• https://www.myetherwallet.com/
• My address or public key
0x595F556aAEf0066536C128D4786389b07c8BbBb2
• Ethereum network – Ropsten network
• Test ether for Ropsten network
• https://faucet.ropsten.be/
• Test editor
• https://www.sublimetext.com/
• Existing contract
• https://www.github.com/bitfwdcommunity
• Ethereum compiler
• http://remix.ethereum.org/
• Modify the existing contract using Sublimetext to define
• Own crowdsource project
• Own tokens (UJI)
• ICO parameters such as number of tokens per ether, time to avail
bonus, time to end of crowdsource project
• Compile the code using ethereum remix
• Use myethereumwallet to create & deploy the contract
(use test ether from https://faucet.ropsten.be)
• Register and verify the contract for others to interact with
it using etherscan (https://ropsten.etherscan.io/)
• Check that the UJI tokens are being issued (By sending
ether to contract using myethereumwallet)
- Please use any ethereum wallet which provides Ropsten ETH
- Use the wallet to send ethers to my ICO contract address
below
- Contract :
0xf70A17FE1E686dD29beCbcd71f2fb506f8fb19fE
- Check the wallet for custom tokens and search for UJI Tokens
- For every 0.001 ethers you sent to the address above you
should receive 1.2 UJI tokens
- After the bonus period for every 0.001 ethers you sent to the
address above you should receive 1 UJI tokens
- THANK YOU
- HAPPY TO RECEIVE ETHERS FOR MY ICO !
