Streamflow is currently generating revenue in three ways:
SOL transaction fees upon each Vesting/Token Transfer/Locks/Staking contract creation as per Costs of Using Streamflow
One-time fee (in stablecoins) for unrestricted access to the platform
Custom offerings available for enterprise-level projects
With the launch of upcoming products, as well as the progressive decentralization and the STREAM, there are many more ways for Streamflow to accrue value via different revenue streams (e.g., through SPL staking rewards, launchpad fees, OTC trades) and the business model will evolve accordingly.
