How can I claim back my XHT after the collateral is locked?

If you've put XHT collateral towards an exchange project of your own and the target collateral amount is met, then the XHT will be locked for a period of 6 months. You can not withdraw the XHT before that time is up. Withdrawing XHT will invalidate any exchanges projects that are using the HollaEx kit.

If your XHT collateral is pooled into a multi-party collateralization scheme then you vote and wait for the majority of voters to unlock the XHT so that it can be freely withdrawn.
