Custom Blockchain Wallet Development

Obsidian Systems specializes in developing secure cryptocurrency wallet infrastructure and applications across multiple platforms including desktop, web, and hardware wallet integrations. Their wallet development service covers the full stack from cryptographic key management to user interface design, enabling blockchain ecosystems and applications to provide seamless wallet experiences.

Wallet Infrastructure Capabilities

Key capabilities include hardware wallet integration (particularly Ledger devices), multi-signature support, transaction signing and broadcasting, address management, balance tracking, and support for multiple blockchain networks. They build wallet infrastructure that prioritizes both security and user experience, making complex cryptographic operations accessible to end users.

Their Haskell-based development approach provides strong security guarantees for wallet software, critical for applications handling user funds. They have established relationships with hardware wallet vendors like Ledger, as evidenced by Ledger Security Audit feedback praising their app as a potential "reference for other app developers."

Major Wallet Projects

Kadena Chainweaver Wallet: Desktop wallet application for the Kadena blockchain supporting Mac, Linux, and Windows with full key management and transaction capabilities.

Nervos Ledger App: Complete Ledger hardware wallet integration including the Ledger app itself, LedgerJS support, abstract hardware wallet support in CKB-CLI, and CLI plugins.

Tezos Kiln: Desktop GUI app for Tezos validators that includes wallet functionality with hardware wallet support, demonstrating "PHENOMENAL user experience for such an extremely technical endeavor in crypto."
