The initial liquidity will be provided via Masternode Collaterals. The masternodes will be incentized required to create lightning channels with each other and moreover to end user.

How this works is the Masternode collaterals would need to be decreased and must be held in an even number in an address marked as a masternode collateral lightning channel address. Further details are underwraps and will be revealed closer to release date.

There will be a fee model for masternodes. Masternodes will earn masternode rewards in addition to fees. Fees for DEX would come in the form of watch tower services, which is pay per contract/trade. Pay per transaction via lightning for routing and light wallet functionalities. Basically any type of resource intensive work done by masternode network would require fees. These fees will go to the relevant masternodes as fee rewards in addition to the masternode collaterals.

Stakenet is building out its masternode ecosystem, and dApps will soon be built on it.
