Securypto is based on PIVX, just like PIVX is based on DASH and DASH on bitcoin. We are working on our own blockchain which is similar to PIVX in code. So we have our own blockchain. However to raise funds we use the ethereum network token for now and tokens will be swapped later for SCU which is the native token on the Securypto blockchain.

Other ICO's use only eth to raise funds, we are creating our own blockchain!
