LND Anchor Output Errors - Fix Reserve and CPFP Fee Bumping

What Are LND Anchor Outputs?

Anchor outputs allow either party to fee-bump a force-close via CPFP when on-chain fees spike, preventing stuck channels.

Common Errors

• insufficient funds for anchor output reserve
• cannot open channel: anchor channel requires 10000 sat reserve
• force close transaction not confirmed: anchor CPFP failed

Fix: Fund the Anchor Reserve
