Hello there! Today we would like to give a quick walkthrough of our new token sale function in the O3 app. The screenshots are for iPhone, but it works the same for Android!

To start, open the O3 app and push the round + button. On iPhone it’s on the bottom middle, for Android it’s on the right side of the screen. When you click the + button you can click ‘Token Sale’.

Next you will see the below screen. If there are no token sales available you can sign up for the token sale newsletter and get notified when a token sale launches in O3. We won’t use your e-mail address for anything other than this and will never give it out to third parties.

If there is a token sale, you will see the below screen. Here it shows what the token sale is about and how long it is open for. The O3 wallet will check your wallet address with the smart contract of the corresponding token sale. If you are not whitelisted/eligible for the token sale, you will not be able to participate.

In our case, we’re whitelisted for the O3 token sale. Awesome! Let’s get some of these sweet O3 coins and off to the moon we go! Click participate to go on.

Next you get to the token sale page. You can find the basic info on the token, and the amount of money being raised. You can choose whether you want to participate with NEO or with GAS but depending on the token sale it might be limited to one of the two.

Now if you want to participate with NEO click on the bar that says NEO, if you want to participate with GAS click GAS (easy huh?). Fill in the amount of NEO or GAS you want to put towards the token sale. You can also select a percentage of the total amount of tokens you hold. In case of NEO it will get rounded off because NEO is indivisible.

If you want to, you can select to send your transaction with priority. This will cost you a bit of extra GAS, but your transaction will get prioritised over ones that do not pay this bit of GAS. This can be useful in case the token sale is quite popular and everyone is sending at the same time.

*PLEASE NOTE: These GAS network fees for priority transactions will be sent to the consensus nodes, O3 is not receiving any of these fees and is in no way responsible for whether your transaction goes through or not.

Next click the review button and you will see a screen to do a final check. Here you see how many NEO you are sending, how many tokens you will receive in return and you will have to agree to the terms of the token sale.

If you agree with all the terms click the checkboxes and then click participate.

Now your transaction will be sent to the NEO blockchain, this shouldn’t take more than 30 seconds.

Woohoo!! We succeeded! Here you can see an overview of the transaction details.

It is highly recommended that you save these transaction details. If anything goes wrong or you have any questions about your participation for the token sale you can use this when contacting the respective team.

After saving the transaction details you can go back to the main wallet screen.

If the smart contract is designed to automatically mint your tokens you just have to refresh the wallet by swiping down, and after a bit your tokens should show up!

Now some smart contracts do not automatically mint your tokens. In that case your address gets registered and the tokens will be sent to your address at a later stage by the teams that are organising the token sale. We will always show you whether you get the tokens directly or not, but if you have any questions regarding the token delivery please contact the project organising the token sale.

That’s it, simple and easy right? :)

If you have any questions or suggestions to make this service better please do leave a message on the O3 community website:
