Currently, the only exchange that MAY be participating in the Airdrop is KUCOIN where PRL is traded.
Oyster is still awaiting final confirmation.
As always with any airdrop, it is highly recommended that PRL holders who want to receive SHL tokens store their PRLs outside an exchange in a personal wallet.
The Shell (SHL) token, is a utility token that will be used to pay for connectivity and Dapp operation across the Oyster meshnet
Pearls (PRL) on the other hand, are used for static data retention on the tangle.
In the future you will be able to use Shells to access the decentralized web, connectivity that entirely bypasses ISPs and centralized infrastructure (very ambitious project)!
This airdrop will be the only way to attain SHL, it will not be offered in a token sale.
1 PRL held on the blockchain will be airdropped 1 SHL. The total supply of SHL will match the total supply of PRL (after the 10m PRL coin burn event).
Airdrop ratio 1 PRL : 1 SHL
