Non-developer here. I have just read Pundi X's blog post about their proposed forthcoming token split and I am curious about how they could implement this:
They plan to give token holders an additional 999 PXS for every 1 PXS they already hold. However the current total supply of 36,104,947.59 PXS would not be nearly enough to cover the number of additional tokens required:
I can't imagine that it would be possible for them to retroactively increase the total supply of an ERC20 token. Is this possible or would they have to create a second token with 1000x supply and airdrop this on a 1000:1 ratio to current token holders instead?
