Transmitter Pearl
Transmitter Pearl is a Fabric equipment mod for 1.21.1 that lets a player link two living entities and swap their positions with a single pearl.
What it does
Right-clicking a living entity sets it as a target, and shift-right-clicking an air block sets a target position for the player. Once two targets are locked, a left-click with the pearl triggers the swap, and the two targets can sit in different dimensions, such as the Nether and the Overworld. Shift-left-click clears the active links and resets the pearl. Each of the pearl's two targets is recorded by a distinct signature, and every transmission draws on the pearl's internal energy, which gives it ten uses in total before it becomes unstable.
The pearl's durability can be kept up by repairing it with Redstone Blocks. Once its durability is fully depleted, it shatters and reverts to a standard, non-functional Ender Pearl. On multiplayer servers, a linkTrust gamerule keeps players from linking others unless they are explicitly granted permission. The mod is client and server, so both the server and every player need it. The code is released under CC0 1.0 Universal, so the mod is open source and the source code is public.
Key features
Entity linking
A pearl can link two living entities and swap their positions regardless of the distance between them.
Cross-dimension swaps
Targets may sit in different dimensions, so a swap can move an entity from the Nether to the Overworld.
Limited pearl uses
Every transmission drains the pearl's internal energy, so it lasts for ten uses in total before it becomes unstable.
Trust system
A gamerule restricts linking to players who have been explicitly granted permission, which helps on multiplayer servers.
Repair and reset
Redstone Blocks repair the pearl's durability, and shift-left-click clears active links and resets it.

How it compares
Key Pearl is a Fabric mod for 1.21.1 that runs client-side only, so it changes nothing on the server, and it is released under All rights reserved, so it is not open source. AuraPearl is a client-side Fabric mod for 1.21.1 – 1.21.11, also under All rights reserved and not open source. Transmitter Pearl instead needs both client and server and is open source under CC0 1.0 Universal.
