STAKE Staking Token FAQ

If I only need xDai coins for transactions, what is STAKE used for?
STAKE is a volatile token used as a staking token to protect the xDai chain. It enables delegated staking and community participation in xDai consensus. It is also used for STAKE weighted proposal initiation and voting.
You do not need STAKE to use the xDai chain for regular transactions. You only need STAKE if you want to be a validator or delegator on the xDai chain or to participate in governance.

Why is STAKE an ERC677?
ERC677 is very similar to an ERC20, but includes additional functionality. We use the transferandCall functionality to enable easier bridge conversions, moving STAKE from the Ethereum Mainnet to the xDai chain and back.
For more information see the EIP677 standard https://github.com/ethereum/EIPs/issues/677.
What is multi-chain staking?
xDai is the first developed use-case for STAKE. However, it may be adopted by other chains in the future and used as a staking token for their consensus as well. POSDAO consensus is an algorithm we’ve developed that may be adopted by other chains, and those chains would have the opportunity to also incorporate a ready-made solution with STAKE to protect their chain.
Can I move STAKE on the xDai Chain directly to the Huobi Exchange or AscendEx exchange?
Huobi
To move to Huobi, you will first need to have your STAKE on the Ethereum mainnet as an ERC20. If you currently have STAKE on xDai, you should bridge it back to Ethereum with the OmniBridge before sending to the Huobi exchange. 
If you send STAKE on xDai directly to Huobi, the xDai team cannot help with this issue and you will need to contact Huobi directly.
Note: The transfer operation between xDai and STAKE can be costly, more on gas fees associated with bridging to Ethereum.
AscendEx (formerly BitMax)
It is possible to send STAKE on xDai to the AscendEx exchange. Be sure to connect to the correct chain when sending STAKE to AscendEx. More information​
Note: if you have STAKE on xDai on AscendEx and want to transfer it to Huobi, be sure to exchange it to STAKE on Ethereum before transferring between exchanges.
