But what about the spaceships?
The Verge is science fiction, so it has to have spaceships, right?
Well, sort of. People certainly want to get to other worlds, or asteroids, or other places far away from the world that they live on.
However, most of these needs can be met by wormholes.
As noted above, a wormhole with a jet of stuff shooting through it has the same physics as a rocket.
So, the projected wormhole mouth is itself the spacecraft.
But using wormholes for your spaceship has lots of advantages.
For example, you get to leave the engine back home. And the sensors, power plant, heat rejectors, crew, and all the other stuff you need to make a rocket work.
Just shoot the rocket jet through the wormhole, look through the wormhole with your sensors, and so on.
The crew are not so much crew as mission control, working in shifts at a control room to direct and operate the wormhole and the rest of the equipment needed to make it work and get it where you want it to go.
The mission control room might look like the bridge of a spaceship, but when their shift is up the crew can go back to their own homes and families for the night.
In addition, if something goes horribly wrong, you can lose your wormhole but you don't lose the lives of the people operating the craft.
If you want to get anywhere where there is already something there (like a world, asteroid, or artificial satellite), you launch a small wormhole mouth. It will be a few milligrams and steered by high powered lasers (for Humans) or tractor beams (for Gummis and Mants). When the wormhole gets there, it can gobble up the mass at the object in order to exchange with the mass of the people and equipment coming through.
In this way, valuable siderophile elements can be taken from asteroids and replaced by worthless gravel; people can be sent to other worlds in exchange for dirt, air, or water; and satellites can be drawn through, repaired, and then put back.
This leaves getting somewhere when there is nothing there. Which begs the question, why would you want to?
Close to a planet, satellites are still very useful for communication, planetary observation, and geolocation; and you need to put them in orbit where no pre-existing mass is conveniently floating around to be scooped up.
Consequently, Humans make aerospace rocket planes to loft satellites up into orbit.
Although usually they leave the satellite at home and loft a bunch of water with the same mass as the satellite and a wormhole mouth instead, and then trade the water for the satellite once the rocket is in the right orbit.
This greatly cuts down on the risk of losing your expensive satellite if the rocket blows up or crashes, as rockets sometimes do.
Mants and Gummis use tractor beams instead of rocket spaceplanes, projected from base stations on the planet to push and pull the satellite until it is on the proper orbit.
Farther from a planet, there is not much demand to put things out in empty space.
However, there are situations where this is desired - the gravitational focal point of a star makes a convenient spot for astronomical observation, and Antecessor relics are often found in deep space (and not likely to sit idly by while their mass is gobbled up or while they are being engulfed in a wormhole for transit to a planet).
These situations lead to the closest the Verge usually comes to a traditional spacecraft.
A convenient asteroid or comet is located on an orbit that minimizes the delta-V needed to reach the mission objective.
A milligram wormhole mouth is launched to this orbiting body, which serves as a source of mass to build the wormhole mass up to whatever the mission requires.
Powerful NOW reactors are used to shoot jets of atomic-hot plasma through the wormhole to act as a rocket torch, propelling the wormhole spacecraft to its target.
Probes, instruments, or other equipment can then be put out in deep space.
In the case of an Antecessor artifact, weapons and deflectors might be needed if the artifact is still operational and cranky about being boarded and looted; as well as away teams of researchers and the officers and security personnel needed to protect the researchers from Antecessor defense bots and death fields.
These defenses are kept back at home and projected through the wormhole, and the people kept there as well until they are needed for their job.
