We will be issuing the PRSM smart contract on Ethereum in the next couple days. As we state here on the website and the upcoming Whitepaper, PRSM tokens will be issued on the Ethereum blockchain as a ERC20 token as a holding token. This is because the Presiam private blockchain/wallet hasn't been completed. These Ethereum PRSM tokens will be swapped out for Presiam PRSM tokens once blockchain/wallet is complete.
It's important that for all Airdrop recipients that you hold onto your Ethereum PRSM tokens so that you can get them swapped out.
