1. We have upgraded the Betting dApp

We have added several features to our Betting dApp

Now you can specify the minimum and maximum value of the bet, and also set the time limit — the block number, after which the bets can no longer be made.

Try it now in dApp Builder Marketplace

2. Gas price Pop-Up

We created a Pop-Up window for setting the gas price for your transaction before opening the MetaMask window. By default, the gas price is set as the current gas price in the blockchain + 1 Gwei.

3. Smart contracts verification

We have done the smart contract verification on Etherscan for the Custom Token and ICO Token dApps.

Etherscan API does not support automated verification for smart contracts, so you need to do it manually.

To verify a smart contract, you need to:

1) Go to the My dApps or My Test dApps page in the dApp Builder interface and select your token application that you want to verify.

2) Click “Verify smart-contract” button. You will see a pop-up window with all the necessary information to verify the smart contract.

3) Go to the https://etherscan.io/verifyContract (Main Net) or https://rinkeby.etherscan.io/verifyContract (Rinkeby Test Net) page and copy-paste the information from the pop-up to the form, pass reCaptcha and click “Verify And Publish” button.

4) If everything is done correctly, you will receive a message about the successful verification, and your contract will be verified.
