“There are three different layers in the cardstack framework
The first layer – This is the secure ledger layer, it is basically focused on the mechanism of application of the blockchain technology in Ethereum, which is the cryptocurrency the token is based on.
The second layer – this layer is called the scalable payment and governance layer. It involves the cardstack token – CARD and the aggregation protocol known as Tally. Tally uses cryptographic proof-of-usage protocol to verify and validate transactions to the smart contract. Consequently, Tally improves the experience by reducing the demands on the Ethereum blockchain.
The third layer – the final layer, known as the orchestration and experience layer, this layer is all about the general framework of the cardstack hub and card based blockchain applications.”

Please note: Transactions will be disabled while we perform the upgrade.

The upgrade is planned to begin Tuesday, Sep. 11, at 9:00 AM EST (15:00 CEST) and will last an estimated 8-12 hours.

Cardstack's smart contract upgrade is now complete.

The new, official address for Cardstack Token (CARD) as of September 12, 2018 (00:00 UTC) is:

0x954b890704693af242613edEf1B603825afcD708

This address may be verified by looking up our ENS address, cardstack.eth: https://etherscan.io/address/cardstack.eth

Exchanges have been notified of our new address and will be updating their systems to reflect this soon. Direct token transfers are now reactivated.

If you have Cardstack Tokens: You do not need to do anything, except to use the new address going forward! We want to make sure you have a great user experience, so the hard part of swapping tokens and transferring balances has been completed and paid for by our team.

This major upgrade also enables us to make future upgrades without changing our contract address, to further improve the user experience.

Funny of course .. The team raised $ 35 million, and now the market cap is only 4.2 million tokens. And this is in fact taking into account the tokens of the advisers and the team that have already been unlocked .. Some bench projects and that look nicer.

UPDATE: There may be a few reporting issues with CARD as the transition to the new smart contract takes place. Please be patient as the reporting tools update.
