# Default network ports
> This page lists the default ports used by **Midaz** and the **plugins**. If you're deploying in a self-hosted environment, we recommend checking if the required ports are available and open in your infrastructure.
These are the default internal ports. If you're using Docker Compose, Kubernetes, or a cloud provider, port mappings may differ. Always verify your configuration before exposing services publicly.
## Core services
***
| Service | Port | Name |
| :---------------- | :--- | :----------------------- |
| Midaz Onboarding | 3000 | midaz\_onboarding |
| Midaz Transaction | 3001 | midaz\_transaction |
| Midaz Ledger | 3002 | midaz\_ledger |
| Transaction gRPC | 3011 | midaz\_transaction\_grpc |
| Midaz Console | 8081 | midaz-console |
| Matcher | 8080 | matcher |
## Plugin services
***
Each plugin runs as an independent service and may expose its own API or background processes.
| Plugin | Port | Name |
| :------------------------ | :--- | :--------------- |
| Access Manager - Auth | 4000 | plugin-auth |
| Access Manager - Identity | 4001 | plugin-identity |
| Fees Engine | 4002 | plugin-fees |
| CRM | 4003 | plugin-crm |
| Reporter Manager | 4005 | reporter-manager |
For better security, expose only necessary ports (like Console and MCP) and restrict others using firewall rules or internal networking policies.
## Customization
***
You can change the default ports using environment variables, Docker Compose files, or Helm values, depending on your setup. If you override a port, make sure to update any references across your infrastructure, load balancers, and API consumers.
