Engineering
Turn a BCH product idea into something people can use.
We built OPTN Wallet and the supporting BCH stack ourselves. Now we help teams apply those lessons to wallets, CashToken apps, and controlled transaction workflows of their own.
Illustrative engineering path
Apply the stack
The same expertise, applied to your product.
Wallet and application integration
Connect your product to BCH apps, wallets, and transaction flows.
CashTokens and BCMR
Make token balances, metadata, and user experiences work together.
CashScript and covenant patterns
Design transaction rules for workflows with real constraints.
Backend, testing, and deployment
Build services, adversarial test harnesses, and release checks that keep a workflow ready for launch.
From product idea to launch
Define the workflow, threat model, constraints, and outcome you want to reach.
Work through architecture, implementation, or transaction design.
Test failure paths, review integration points, and get ready for release.
Proof behind the work

What we currently support
Current fund-level enforcement work is scoped to BCH and CashToken funds deliberately placed under BCH covenant control.
