Node Tags

Wumbo classifies Lightning nodes using heuristics, metadata, and network topology.

Implementation

Identifies the node software (LND, CLN, Eclair, LDK) using default feature bit patterns. Can be spoofed.

Outbound Fees

Based on the outbound fee-rate (PPM) a node sets on its channels. Higher fees generally indicate active routing nodes.

Inbound Fees

Based on the inbound fee-rate (PPM). Inbound fees are a newer feature where nodes charge for receiving liquidity.

Rank

Percentile rank by total public channel capacity.

Network

Based on advertised connection addresses. Nodes can be clearnet-only, Tor-only, hybrid, or broadcast no address at all.

Wumbo

LND limits channels to ~16.7M sats by default. Wumbo-enabled nodes accept larger channels.

Disabled Channels

A disabled channel stops forwarding from one side. If both sides are disabled, no routing is possible.

Alias

Nodes optionally broadcast a UTF-8 alias. Tags detect emoji usage, domain names, or no alias at all.

Color

Nodes broadcast a 3-byte RGB color. Nodes sharing a color are grouped together.
