Products and infrastructure for Bitcoin Cash
Wallet software, token data, and hosted services for Bitcoin Cash
OPTN Labs builds products and infrastructure for the BCH ecosystem, from end-user wallet software to developer tooling and hosted backend services.
We also help teams build wallet products, token systems, contracts, and backend services on BCH.
What we do
We build for the BCH ecosystem from three angles: end-user products, developer tooling, and company infrastructure.
Live services
A few services we run today. Status appears when the service exposes a usable health check.
Products
The main things we offer today.
OPTN Wallet
A BCH wallet for end users and a reference app for developers.

- •Electrum, Chaingraph, BCMR, and IPFS
- •Public endpoints and request-based access
- •Built to support wallet and app teams
Engineering Support
Direct engineering help for teams building products on BCH.
- •Wallet and token integration work
- •Contract and transaction flow design
- •Backend architecture and launch support
Use cases
The kinds of products we most often support.
Payments & App Backends
Wallets, payment products, and app backends that need BCH monitoring, metadata, and history.
- •Index and query on-chain activity
- •Serve token metadata and media
- •Monitor payments and confirmations
Covenant-Powered Workflows
Escrow, staged spends, restricted transfers, and other custom transaction flows.
- •Escrow and conditional releases
- •Restricted spends and recipient controls
- •Multi-party or staged transactions
Token Launch & Control
CashTokens projects that need metadata, issuance controls, and lifecycle visibility.
- •BCMR + metadata distribution
- •Media hosting via IPFS gateway patterns
- •Issuance and lifecycle monitoring
Product proof from OPTN Wallet
The wallet is not separate from the Labs story. It is where advanced BCH transaction flows, token UX, and covenant-oriented patterns get tested before they become guidance, product decisions, or reusable implementation patterns for teams.
Writing & code
Recent writing, source code, and a few references tied to our work.
