Hey Marino!
Unstaking of SOL on Solana takes 1 epoch (2-3 days). Unstaking JUP takes 30-day cooldown. I guess a 15-day cooldown is a good middle ground, as it gives time to retain collateral in case there was any slashing event.
As for points — deBridge has a deBridge points campaign which is some sort of loyalty program that accounts loyalty points for different activities that add value to the ecosystem.
Season 1 of the points campaign concluded with an airdrop, where 6% of the total supply was distributed proportionally to all point owners.
DAO still has 11%+ of the total supply in the “Community and launch part” which is intended to be distributed to the community over the next 3 yeards, through future seasons of the points campaign (Season 2 is live now). So you can think of deBridge points as an analog for Jupiter’s Jupuary.
I’d think about adding more utility, like discounted bridging fees for stakers or giving the top 10% of stakers first choice on airdrops from partner projects.
Users get points accounted for fees paid, so they get exposure on future seasons of the points campaign.
In v2 of deBridge Liquidity Network, we’ll move the ledger off-chain drastically lowering the operational costs, so DAO will be able to impose fees only on solvers while rebating them in the form of DBR. This can also open a room for discount mechanics that you suggested — solvers will provide tighter spreads for users with voting power. DAO can set Tier levels based on 30d volume and voting power — similar to VIP levels that Binance grants depending on volumes and BNB stake.
Your point that delegation is not necessary makes sense too!
