From product to ecosystem
Build the product. Share the foundation.
OPTN Wallet brings BCH payments, CashTokens, connected apps, and advanced tools into one self-custody product. The work behind it also produces resources that can help other teams build better Bitcoin Cash experiences.
That product and ecosystem experience now informs a newer area of exploration: controlled-payment pilots where software can act within owner-defined financial boundaries.
Principles
How we work
Self-custody by design
We build products and tools that let users retain control of their keys and funds.
Open ecosystem
We publish reusable resources and support infrastructure that other teams can inspect, use, and extend.
Self-custody architecture
Customers retain control of their keys and funds.
OPTN provides application and transaction infrastructure around customer-controlled funds. Where a workflow uses BCH covenants, transaction rules can enforce defined financial conditions for funds placed in that workflow.
