Oyster Shell

- Oyster Pearl platform ulitily token

Shells(SHL) are used to pay for connectivity and Dapp operation across the Oyster meshnet, whilst Pearls are used for static data retention on the tangle. Shell is not pegged to storage like how Pearl is. In the future you will be able to use Shells to access the decentralized web, connectivity that entirely bypasses ISPs and centralized infrastructure.
