Oracles Presale Contract

Build Status Coverage Status

Full Test Report Presale contract that records investor's balances and sends ether to presale owner. It allows to set minimum Contrubution amount, start Date, end Date.

To use:

  1. Flat contracts/PresaleOracles.sol by using solidity-flattener
solidity_flattener --solc-paths=zeppelin-solidity=$(pwd)/node_modules/zeppelin-solidity/ contracts/PresaleOracles.sol --out flat/PresaleOracles_flat.sol

  1. Deploy flat file

  2. Call initialize with following params:

    -startTime in unix format

    -endTime in unix format

    -cap in wei format

    -minimumContribution in wei format

    -vault (eth address where funds will be collected)

Example:

"1510291574","1610291574","100000000000000000000","100000000000000000","0x0039f22efb07a647557c7c5d17854cfd6d489ef3"
startTime: `Friday, November 10, 2017 5:26:14 AM `
endTime: `Sunday, January 10, 2021 3:12:54 PM `
cap: `100 eth `
minimum: `0.1 eth `
vault: `0x0039f22efb07a647557c7c5d17854cfd6d489ef3`
  1. Whitelist investors by calling whitelistInvestors with an array ['0x0039f22efb07a647557c7c5d17854cfd6d489ef3']
  2. Let whitelisted investors send money to contract's address OR to send to buy method (0xa6f2ae3a)

How to whitelist a lot of addresses in batch

  1. cd scripts
  2. npm install
  3. open .env file and modify settings:
PRESALE_ADDRESS=0x6F3f79941f89E03D4aF9bDb8BE0623DC24F2bef0
UNLOCKED_ADDRESS=0x0039f22efb07a647557c7c5d17854cfd6d489ef3
RPC_PORT=8549
GAS_PRICE=0.7
  1. run parity with unlocked account from which the deployment will happen. It has to match with your .env UNLOCKED_ADDRESS:
parity --jsonrpc-port 8549 --chain kovan --unlock 0x0039F22efB07A647557C7C5d17854CFD6D489eF3 --password $HOME/FILE_PATH_TO_YOUR_PASSWORD_FILE
  1. Copy list of addresses into scripts/ARRAY_OF_ADDRESSES.json
  2. run node whitelist.js

The script will show you how many total transactions will be generated

Caution:

If you see this error:

- Unhandled rejection Error: Transaction was not mined within 50 blocks, please make sure your transaction was properly send. Be aware that it might still be mined!

it's totally ok because the transaction is still in the queue and hasn't been mined yet.
