The rebrand to the Liquid token will be the first step. That will simply mean we make some changes to the ERC-20 smart contract. This should happen around the time of the launch of the Liquid platform. An alpha of the LDL is expected to be released within the next few months, with a beta to follow later on.
The next step will then be the full mainnet release of the LDL, at which point there will be a token swap. You will be notified well in advance of the plans for the token swap. We will endeavor to make the token swap as painless as possible for all QASH holders, wherever you may store your tokens.
