Both SilverToken and SilverDollar work only on the Ethereum network. In order to use the network for transactions a fee is charged called "GAS". This fee is always paid for with Ethereum (ETH).

So by requiring silver to be purchased with ETH it ensures that the sending wallet is a Ethereum based wallet, and you have gas to pay for the transaction fee.

Aligned with our belief to create sound money, all SilverTokens are fully redeemable on demand for a minimum of 1 : 1 silver. Each SilverToken is fully represented by vaulted silver, and initially the ratio of silver to SLVT started at 1:1 but has since grown, meaning for each SLVT in circulation there is more than 1 troy ounce of 99.9% silver secured within the vaults. All SilverTokens in circulation may be sent back to SilverToken and exchanged for the silver represented by the token (this is called exchanging or redeeming). Thus, SLVT is commodity money. When redeeming, a minimum of 200 ounces must be redeemed.
