OPTN Labs
Bitcoin Cash wallets, tools, and infrastructure.
Bitcoin Cash can do more than simple payments. OPTN builds practical products and supporting layers that make advanced BCH capabilities usable—from a self-custody wallet to developing systems designed to set clear limits around software-operated funds.

From proof to control
Build the stack. Control the outcome.
Once a real wallet works, the next layers become clear: give other builders the tools and infrastructure they need, then explore transaction rules that control what software-operated funds can do.
Programmable fund control
In developmentExplore transaction rules that limit what software-operated funds can do.
As applications become more capable, the question shifts from who can request a transaction to what transactions should be possible at all.
Financial coordination · In development
Give software room to act—with clear limits.
When people, software, or AI need to move money, OPTN is exploring a financial coordination layer that maps requests to permitted transaction outcomes.
The design can cover recipients, amounts, next steps, and recovery—so a signed request is not the only line of defense.
