Built for aBitcoin Standard
A unified operational view across wallets, transactions, infrastructure, and market activity.
Holdings. Aggregate your Bitcoin across self-custody wallets, exchanges, and connected services.
Connect through descriptors, extended public keys, APIs, or secure authentication flows, then organize holdings into flexible groups with custom balance views and shared configurations. Track balances, transactions, and activity from a single watch-only system without private keys.
Receiving
Generate receive addresses across connected wallets without exposing private keys. Route deposits intentionally, organize incoming funds by wallet or purpose, and coordinate receiving from a single interface.
Transactions
A unified transaction layer across all connected wallets. Name and label transactions, attach notes, and organize activity in one place with full historical visibility across accounts and holdings.
Alerts & Notifications
Monitor balance changes, transactions, miner activity, fee conditions, and Bitcoin price movement in real time. Configure granular alerts across wallets, infrastructure, and market conditions from a single notification system.
UTXO Management
Inspect and manage funds at the UTXO level. Split, merge, flag, and organize outputs with precise coin control designed for long-term holders and external signing workflows.
PSBT & External Signing. Prepare, review, and export transactions for external hardware wallets and signing devices.
BNKR keeps the workflow watch-only while making transaction coordination fast and approachable.
Cost Basis & Performance
Track cost basis, realized and unrealized gains, and lifetime performance across all holdings. Analyze income and spending over time with a consistent historical view across wallets and accounts.
Node & Network Integration
Connect your own node and electrum server to independently verify balances, transactions, and network data. Monitor fee conditions and blockchain activity directly from your own infrastructure.
Miner Monitoring
Monitor solo miners alongside the rest of your Bitcoin infrastructure. Track hash rate, uptime, performance history, and miner activity from a unified operational view.
Architecture & Security
BNKR is watch-only by design. Private keys never enter the app, transaction signing remains external, and verification can run through your own infrastructure. The system is built to provide operational visibility without custody.
Exchange Rate
Track the purchasing power of Bitcoin across currencies, assets, and time. BNKR approaches price from a Bitcoin-first perspective, where exchange rates are measured against Bitcoin rather than treating Bitcoin as another traded asset inside a brokerage interface. Monitor exchange rates, historical performance, portfolio impact, and price conditions across multiple data sources through a charting system designed for holders, not traders.
