# General message passing

All transactions on Strobe Protocol involve general message passing (GMP). A GMP through Axelar goes through three steps in its path:

1. Source blockchain (XRPL)
2. Axelar
3. Destination blockchain (EVM Sidechain)

An example of a [devnet GMP can be located here](https://devnet-amplifier.axelarscan.io/gmp/0xdcb88c59f2a4c3721d0a5bbbfefc98bb73bbf9a08c2d229d46fe7d65a551f5af-71565).

You can use Axelarscan to track your transaction initiated from XRPL. Please refer to the following links:
