There will be no token swap initially. The rebrand is really just changing the name and ticker of the token in the ERC-20 smart contract. This will not require any kind of token swap. Later down the line, with the full release of the LDL, there will be a token swap of the ERC-20 tokens to the new mainnet tokens, but this is still some way off.
We will notify you well in advance on the process of the token swap, but it’s not something you should be concerned about.
