OPTN Wallet is a self-custody Bitcoin Cash wallet for BCH, CashTokens, connected applications, and advanced transaction workflows. In 2026, the project has expanded across Android and desktop, alongside developer-facing experiments in payment tooling.
Google Play currently shows 500+ downloads and lists the app as updated on August 16, 2026. The stable v1.7.3 GitHub release was also published on August 16. This is a current-state update: what is available now, what we are still refining, and what remains experimental.
The goal is straightforward: make Bitcoin Cash useful without requiring users to understand every UTXO, token field, connection protocol, or transaction detail underneath it.
A Bitcoin Cash wallet built to interact
At the product level, OPTN Wallet lets users send and receive BCH, manage CashTokens, connect to compatible applications through WalletConnect, and work with more capable transaction flows from one self-custody wallet. The Wallet page describes the current user-facing surface.
The wallet is being built around the BCH application layer. That means the product has to handle more than balances and addresses: applications may ask for a connection, token-aware transactions need a clear explanation, and advanced flows need boundaries that users can understand before they approve anything.
The add-on model is the next step in making wallet capabilities extensible. The system remains in development while we refine its permission and integration model. The design goal is simple: an application should be able to request a wallet action without automatically receiving unrestricted control over the wallet itself.
Improving the everyday wallet first
A lot of recent work has been less visible than adding a new headline feature.
The August stable update focused on reliability. Its public release notes list improvements to wallet synchronization, balance updates, transaction history, watch-only PSBT and QR transfers, merchant-payment flows, CashConnect, payment handling, localization, diagnostics, and general stability.

That work matters because advanced transaction features are not very useful if the basic wallet experience is unreliable.
A wallet needs to know what it owns, show it correctly, construct the intended transaction, make the result understandable to the user, and broadcast it reliably. Every higher-level integration depends on those foundations working first.
CashTokens as a first-class wallet primitive
CashTokens are one of the areas where OPTN Wallet goes beyond basic BCH transfers.
Bitcoin Cash can carry fungible token amounts and NFTs directly inside transaction outputs. That means token handling is part of the transaction model itself rather than a balance maintained by a separate smart-contract account.
For a wallet, that creates additional responsibilities. It has to select token-bearing UTXOs correctly, construct token-aware outputs and change, and show the user what a transaction will do before it is signed.
OPTN Wallet treats those flows as native wallet behavior rather than an external token interface bolted onto a BCH wallet.
This article is not another CashTokens tutorial. For the protocol and implementation layers, see the CashTokens guide, CashTokens in practice, and production wallet failure cases. The wallet gives us a practical environment for testing the CashTokens and BCMR infrastructure we build across OPTN Labs.
Connecting the wallet to BCH applications
Application connectivity is the other major direction. WalletConnect is the current public path for connecting OPTN Wallet to compatible external applications.
That opens the door to a wallet that can act as an interface to more of the BCH ecosystem.
A user should eventually be able to discover an application, understand what it is requesting, review the transaction that results, and approve or reject it without needing to manually reconstruct what happened at the protocol layer.
That is the direction behind our work on application connections, transaction construction, token support, merchant flows, and contract interaction. The developer resources provide the surrounding integration and implementation context.
Android and desktop distribution
Google Play is the straightforward distribution path for the stable Android application. The v1.7.3 GitHub release also provides downloadable builds for Windows, macOS, and Linux.
The release notes distinguish these channels for a reason. Mobile is the easiest path for everyday users, while GitHub exposes source code, release artifacts, and implementation context for developers and technical users. iOS is not included in the current v1.7.3 release.
Stable wallet, new payment experiments
It is important to distinguish the stable wallet from public development work.
The v1.7.3-alpha.41 prerelease, published on August 30, includes a headless wallet with x402 payments, CashTokens support, and agent skills, alongside additional desktop, PSBT, and connection work. These capabilities are prerelease experiments, not features of the stable Wallet release.
Software and AI agents may need to receive BCH, manage UTXOs, compose transactions, pay for APIs and services, and participate in automated workflows. This creates new payment and wallet requirements beyond the familiar person-with-a-phone flow.
As agent authority grows, programmable transaction rules can define payment amounts, destinations, transaction composition, and what happens next. OPTN is exploring these problems through its separate in-development programmable-payment work, including how BCH covenant rules apply to funds deliberately placed under that control.
OPTN Wallet shaped the wider stack
OPTN Wallet matters to us for another reason: it forces us to work with Bitcoin Cash as a real product environment.
CashTokens are not an abstract specification when a wallet has to handle token change correctly. WalletConnect is not just an integration standard when a user has to understand what an application is asking them to sign. Covenant contracts are not just scripts when a wallet has to construct the exact transaction that can spend them.
The Wallet gives us a place to encounter those problems directly. That work feeds into the broader tools, infrastructure, and programmable transaction systems we are building at OPTN Labs.
We build infrastructure alongside the products that depend on it.
Where we are now
OPTN Wallet is available today for self-custody BCH, CashTokens, application connections, and advanced transaction workflows.
Alongside the stable wallet, we are exploring richer desktop experiences, developer interfaces, machine-operated payments, covenant interaction, and new ways to connect BCH applications while keeping wallet permissions explicit.
These experiments are helping shape the next generation of OPTN products—from connected-wallet experiences and developer tools to autonomous payment infrastructure.
The common thread is the same:
make Bitcoin Cash easier to use without hiding what controls the transaction.
