Streamflow is currently generating revenue in three ways:
0.117 SOL transaction fee upon each Vesting/Token Transfer/Locks contract creation
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.
