Streamflow is currently generating revenue in few ways:
0.19% transaction fee (in kind) taken upon each withdrawal
$19 999 one-time fee (in stablecoins) for unrestricted access to the platform
Custom offering available for enterprise-level projects
With the launch of Streamflow v2 and STREAM, there are more ways for Streamflow to accrue value via different revenue streams (e.g. through SPL staking rewards, launchpad, OTC deals, via lending against payment streams), and the business model will evolve accordingly.
