* Description: Silver The Hedgehog ($SILVER) Official Token Contract
*
* BIO:
* Silver the Hedgehog (シルバー・ザ・ヘッジホッグ Shirubā za Hejjihoggu?) is a character that appears
* in the Sonic the Hedgehog series. He is an anthropomorphic hedgehog who travels back in time from
* two hundred years into the future. His goal is to preserve peace in his future by resolving the
* catastrophes of the past, resulting in frequent interactions with Sonic and other denizens of the
* time. For his missions, Silver can access powerful psychokinetic abilities, which in his time are
* considered the norm, and which allow him to manipulate physical objects with the power of his mind.
