Custodial Tether wallet and OTC platform
TetherBaax
A custodial Tether wallet with instant buy and sell, launched on the BitBaax exchange core with only its own business logic and client surface added.

Context
What the system had to do
The company wanted a second consumer product — a simple Tether wallet with OTC pricing — without forking or destabilizing the exchange it would depend on.
What I built
Decisions and delivery
- Defined the boundary between the shared exchange core and product-specific logic, so a second platform could launch without modifying the underlying system.
- Built the OTC client surface and the instant buy/sell flow on top of the existing trade engine, wallet and custody infrastructure, exposing an OTC capability of the core that BitBaax itself does not surface to end users.
Outcomes
What it delivered
—
Launched with no changes to the exchange core — a live test of the module boundaries.
—
Reused the trade engine, wallet and custody infrastructure instead of rebuilding them.
