“Shell tokens” or “shells” are what we call LP tokens in the Shell Protocol. They represent a claim on the underlying reserve assets held by the pool. The ERC20 ticker for shells is $SHL. Shells should not be confused with the protocol governance token (which is yet to be issued). The tentative ticker for the governance token is $SEA.
I think that “shells” could be a powerful meme, especially down the road when the protocol is crossing the chasm from early DeFi users over to mainstream adoption. If you knew nothing about DeFi, would you rather have some shells or some CRV?
Having the best core protocol is important, but so is having the best memetics. A github repo can always be forked, an algorithm can always be reverse engineered. Our brand and the concept of “shells” as an asset class is unique to us.
Therefore, promoting the term is probably in our strategic best interests.
