Part of Epic: Breez SDK Integration for Expo App (epic:97fd7dcb-10ec-46a8-b681-b2805eb0eb56)
SRS Spec: spec:97fd7dcb-10ec-46a8-b681-b2805eb0eb56/a8f8bef7-d1c5-4113-a9ad-6092120bfe76

Overview

Implement channel management and monitoring: automatic channel opening via Breez LSP, channel list view, balance/capacity display. Use Breez SDK listChannels(), nodeInfo(), and channel/sync events.

Related SRS Requirements: FR-CH-001, FR-CH-002, FR-CH-003, Section 7.5.2

Tasks

• Rely on Breez LSP for automatic channel opening on first receive; show progress and notify user
• Display total Lightning balance (local balance), total channel capacity, inbound/outbound liquidity (from nodeInfo(), listChannels())
• Channel list: all channels with peer, capacity, local/remote balance, state (pending, active, inactive, closed)
• Channel details: channel ID, funding tx, age, total sent/received
• Real-time updates via SDK events (channelOpened, channelClosed, syncComplete); list updates within 500ms of state change
• Filter channels by state; handle channel opening failures gracefully (notify, retry option)
• Display balance in sats and BTC; optional progress bar for capacity utilization

Acceptance Criteria

• AC-CH-001-01 to 05: Auto open on first receive, <30s, progress notification, list update, handle failures
• AC-CH-002-01 to 05: Total balance, capacity, inbound/outbound, update <500ms, sats and BTC
• AC-CH-003-01 to 05: List all active channels; peer, capacity, balances, state; details view; real-time; filter by state

Technical Notes

• Data source: Breez SDK node state and channel manager. Breez SDK handles channel opening automatically via LSP.

Dependencies

• Setup Expo Project with Breez SDK Integration #1 Setup Expo Project with Breez SDK Integration

Closing as implemented on main.

Delivered: ChannelListScreen with state filters, capacity summary, navigation to detail; ChannelDetailScreen (ID, funding tx, balances, capacity bar, pubkey, state); inbound/outbound liquidity in LiquidityBar; channels from WalletContext / SDK. Real-time updates follow SDK-driven wallet state (see wallet context commits).
