@benjaminbollen

it is the Gnosis MultiSig (always with a multisig requirement of 1, so all devices are equal), that is the owner of the users TokenHolder contract (proxy); therefore you need to sign Gnosis SafeTx (similarly executable transactions, etherless but not following EIP1077) to perform wallet operations (eg. adding a new device key, or authorizing a new ephemeral key (is also called a "session key") )

the device keys in the multisig can also "log out", which disables all currently active session keys in the TokenHolder contract

similar to the "executeRule" for executing actions using the executable transactions signed by ephemeral keys within the economy,
to take wallet actions with Gnosis Safe executable transactions, you can use GnosisSafe.executeTransaction https://github.com/OpenSTFoundation/openst.js/blob/develop/lib/helper/GnosisSafe.js#L140

Thank you Benjamin for clarification! I will play a bit with openst.js

Hi everyone, I have few questions related to your Platform.

Benjamin Bollen

@benjaminbollen

Happy to answer

Is it possible for a user to create a wallet in the web browser? Or do you need a mobile app to confirm transactions?

Ankit Yadav

@ankit-yadv

The OST Wallet SDKs support non-custodial wallets, where users hold their keys and can transact with Brand Tokens using their mobile devices.
The mobile-first approach takes advantage of the security features of modern mobile devices to securely generate the required keys on the user's mobile device and encrypt them using the secure enclave (on iOS) or key store (on Android)

There are a number of security advantages to building the wallets into Android and iOS mobile apps and using the security on the devices.

Browser-based solutions are less secure unless implementing a browser extension/plug-in like Metamask does. We have looked at potentially adding something like that in the future but it is not on the near term roadmap since it's a more clumsy user experience, and most companies are very comfortable with and have existing Android and iOS apps, or can launch a new one. In the future we can also look at providing a standalone OST wallet, however our clients tell us they care more about having Brand Tokens in their own apps, so that has not been prioritised at this time.

Thanks @ankit-yadv

Can I split Brand Tokens into small units?

Ankit Yadav

@ankit-yadv

Happy to help @sacOO7

Can I split Brand Tokens into small units?

Brand Tokens are ERC20 based tokens, so they support division up to 18 decimals. Following the SI-naming conventions the smallest denomination is referred to as atto Brand Tokens on the OST Platform.

The denominations are explained further on dev website.

Alright, I also have a question related to stake.

Ankit Yadav

@ankit-yadv

Yeah, go ahead.

@sacOO7

Do we have to buy OST and mint all BTs in advance or can we buy OST as the users obtain more and more BTs?

Ankit Yadav

@ankit-yadv

Do we have to buy OST and mint all BTs in advance or can we buy OST as the users obtain more and more BTs?

The smart contract to create branded tokens requires the full value of all minted tokens to be backed by the stake. There is no way around that requirement.

However, you can mint tokens as you go, so you can start with the minimum required amount and mint more as needed for distribution.

sachin shinde

@sacOO7

That is great.

But how should we calculate the value of a BT? is 1 OST = 1 BT? Or should it be calculated in USD?

Ankit Yadav

@ankit-yadv

But how should we calculate the value of a BT? is 1 OST = 1 BT? Or should it be calculated in USD?

You set the conversion rate between BT and OST before launching the economy. OST Platform sets a default conversation rate of 1OST=1BT. If you like, you can choose to set an alternative conversion rate. Once you mint your token, the conversion rate is fixed and cannot be changed.

Two things to consider when setting the conversion rate:

Order of magnitude of token rewards: do you wish to reward single digit, 10s, 100s, 1000s of tokens per incentive?
Fiat value of each token

sachin shinde

@sacOO7

Where can we set the conversion rate?

Ankit Yadav

@ankit-yadv

You can set the conversion rate during your Brand Token set up in OST Platform Dashboard.

Awesome, thank you.

Hello :) I just received the message from OST launch and I wanted to check the current state

is the REST API still available?

Benjamin Bollen

@benjaminbollen

the REST API is available, but updated, and improved, check out for full documentation https://dev.ost.com/platform/docs/api/#introduction

the new platform is available under https://platform.ost.com

@daan-ost

Hi Ben, question, when adding new users the token_id is always the same 4 digit number. Will that always be the same for all users in the BT environment?

Rachin Kapoor

@rachinkapoor

Hi Daan,
Yes, you are correct

thanks @benjaminbollen

Hi all! I'm new to OST, I was wondering if it's possible to deploy an custom solidity smart contract, like on Ethereum, in OST that can use BT?

Benjamin Bollen

@benjaminbollen

hi @Dionli . yes you can deploy custom solidity contracts;
we even built a framework which we can "token rules" which allows you as an app developer to ensure that your application token only functions in the way you designed it

these token rules can be any custom solidity smart contract, the user can call your contract, and for it to transfer BT, your custom rule contract calls "executeTransfers()" on TokenRules (after being registered) https://github.com/OpenST/openst-contracts/blob/develop/contracts/token/TokenRules.sol#L213

@Dionli

thanks @benjaminbollen !

Hi!

As the OST Platform and OpenST Protocol projects keep growing, there is a need to set up two dedicated communities to funnel the discussions.

Please visit the URLs below to find the two respective communities.

OpenST Protocol: https://discuss.openst.org

Hi guys. Sorry for barging in here. I was looking for the OST wallet where I purchased OST from the IPO. Where can I find those funds? I've been looking for an hour now. Thanks!

Has anyone had success integrating OST Platform into Wordpress to use as an eCommerce payment gateway?

@SaintNSinner81_twitter,

We have moved OST Platform chat to: https://gitter.im/ostdotcom/OST-Platform

I would suggest you to post this message on our new Gitter chat for OST Platform.
