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.

I've got STAKE but can't find it in my wallet.

You may need to add a custom token - Instructions for doing this with MetaMask.

Yes - it is possible on Ethereum with EasyStaking and on xDai with Public POSDAO Staking.

When does public staking start on xDai?

Public staking is now active on xDai.

• Validators: 20K STAKE

• Delegators: 200 STAKE* (Initial amount was 1K, reduced to 200 through a community proposal)

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.
