Receive Methods

• spark — Reusable Spark address (default)
• spark_invoice — Spark invoice with amount
• lightning — BOLT11 invoice
• bitcoin — On-chain address

Payment Flow

Always two-step:

1. wallet_prepare_send → Show fees
2. User confirms → wallet_send(confirmed=true)

Security

• Never expose mnemonic unless explicitly requested
• Always show fees before sending
• Require explicit confirmation for sends
• Wallet data: ~/.openclaw/breezclaw/

Examples

"What's my balance?" → wallet_balance

"Invoice for 1000 sats" → wallet_receive(method="lightning", amount_sats=1000)

"Send 500 sats to [email protected]" → resolve LNURL → wallet_prepare_send → confirm → wallet_send
