Money movement
Send, receive, account, transaction, balance, and history flows stay centered on everyday Bitcoin Cash use.
Bitcoin Cash, built for Apple platforms.
58 Opals builds Opal Wallet and the Swift Bitcoin Cash stack beneath it: practical product work, shaped by careful Apple-platform craft.
Flagship product
Opal Wallet feels native to Apple devices.
The wallet keeps Bitcoin Cash inside platform patterns: SwiftUI surfaces, local persistence, notifications, and system intents move with the product instead of sitting beside it.
Apple fit
SwiftUI, App Intents, local persistence, notifications, platform-aware navigation, and spatial UI readiness make the wallet feel at home across Apple devices.
Infrastructure pull
When product work needs wallet orchestration, cryptography, Fulcrum access, CashFusion, or hedge contracts, the reusable Swift stack gets sharper.
Open infrastructure
Open Swift pieces. One native path.
Each package has a narrow job. Together they let Opal Wallet depend on typed Swift surfaces instead of raw cryptography, raw JSON-RPC, or protocol glue scattered through product code.
App-facing wallet and account domain: mnemonic wallets, deterministic addresses, transaction planning, persistence, CashTokens metadata, and Fulcrum-backed refresh.

Product taste, open foundations, and Apple-platform craft move together.
Product first
Opal Wallet turns the work into real send, receive, storage, privacy, and Apple-platform workflows.
Open foundations
The public Swift packages make the engineering path inspectable for developers who want Bitcoin Cash primitives without leaving the Apple ecosystem.
Native craft
Apple-platform conventions shape the wallet experience and the Swift APIs behind it, so the product and infrastructure feel like one system.
