Toughest in C4 sites: Sleepless Safeguard

Class 4 wormholes

The quiet class. C4s connect to other wormholes and almost never to known space, so nothing casually stumbles through - safer to live in, and slower to move anything in or out of.

B Community-corroborated Two independent community datasets - anoik.is and the MIT-licensed whdbx dataset - agree on the static connections of 2556 of 2567 J-space systems (99.57%). Only the systems both sources agree on feed these figures. Aggregate shape only. Per-system statics are deliberately not published here: no official CCP source carries them, and shipping another project's table needs a licence answer first.

The static wormhole types in C4

Every static is a named wormhole type, and the type sets how much mass the hole takes before it collapses, the heaviest ship that fits through, and how long it lives. That decides how hard your static is to roll, and what you can move in and out through it.

Mass, ship limit and lifetime: A ESI-derived / official EVE's official ESI data for each wormhole type. Which system has which static: B Community-corroborated two community datasets that agree. "Rolling jumps" is the hole's full mass divided by 300M kg, the usual mass of a Higgs-rigged rolling battleship with its propulsion module on. It is a size guide, not a plan: every hole varies by about 10% either way. The rolling guide explains how to do it without stranding anyone.
