Setting aside the question of liquidity mining for now (as it is very much in the design stage, as the core protocol ebbs and flows), we can at least shed some light on our philosophy for the ultimate use case of $SEA and convey some of its future character. That too is much in the early days, but there are some principles we know we will abide by nonetheless.
The first, and most important, is that the token should align incentives across many stakeholders. We must attract a broad ecosystem of cooperation. There will be the core protocol devs, liquidity providers, other protocols, builders, and possibly mass market adoption. Part of the intention of this very topic and forum is to build these lines of communication between us. To us this is a fertile ground where our vision will come to fruition.
A second principle for $SEA is that in order for it to claim value from the protocol, then it must provide value to the protocol. We do not want to construct a system where the token is essentially a means of the right pocket taking from the left. If the token is to reap rewards, it must first offset that cost. This would probably come in absorbing risk for the protocol or enhancing profits. Two brief ideas are:
Employing $SEA to subsidize insurance on deposits into Shell. LPs could stake their $SEA to back the network against a broken peg.
Employing $SEA in parameterizing Shell pools, which will be a nuanced art in the future.
