# ElectrumX Server Infrastructure

### **Why ElectrumX Nodes Matter for Lynx**

As a UTXO-based blockchain derived from Bitcoin, Lynx relies on the Unspent Transaction Output (UTXO) model for tracking coin ownership and balances. ElectrumX servers play a critical role in making this data accessible to lightweight wallets and third-party applications without requiring users to download and sync the entire blockchain.

Traditional full nodes must download every block in the blockchain's history—a process that can take days and consume hundreds of gigabytes of storage. ElectrumX servers solve this problem by maintaining indexed UTXO databases that allow wallets to:

* Query balance information instantly without blockchain synchronization
* Verify transactions quickly using SPV (Simplified Payment Verification)
* Broadcast transactions to the network efficiently
* Access historical transaction data on demand
* Operate on mobile devices and resource-constrained hardware

For UTXO-based projects like Lynx, ElectrumX infrastructure is essential for wallet developers building lightweight clients, mobile applications, and web-based interfaces. These servers act as a bridge between the full blockchain and end-user applications, enabling fast, responsive wallet experiences without sacrificing security or decentralization.

### **Public ElectrumX Nodes**

The following public ElectrumX nodes are available for integration and inclusion with third-party wallets and development partners. Members of the Lynx community donate generous time and resources to ensure these globally distributed ElectrumX nodes remain operational, performant, and synchronized with the latest blockchain state.

```
electrum5.getlynx.io # Milan
electrum6.getlynx.io # Sydney
electrum7.getlynx.io # Chicago
electrum8.getlynx.io # Frankfurt
electrum9.getlynx.io # Toronto
```

{% hint style="warning" %}
Secure ElectrumX ports for Lynx are 50002 and 50004. A non-secure port is not supported.
{% endhint %}

By maintaining multiple geographically distributed ElectrumX servers, the Lynx network ensures reliable access for wallet developers and users worldwide, reducing latency and providing redundancy against server outages.

### **Monitoring and Status**

The operational status of all public Lynx service nodes is [available for real-time inspection](https://status.getlynx.io/). A comprehensive ElectrumX uptime monitoring dashboard tracks node availability, synchronization status, and blockchain height consistency across all servers. [This monitoring tool](https://1209k.com/bitcoin-eye/ele.php?chain=lynx) ensures all ElectrumX nodes remain online and properly synchronized with identical block heights. In the event of a service disruption or synchronization issue, the system automatically notifies the Lynx Core team for immediate remediation, ensuring minimal downtime and consistent service quality for wallet developers and end users.
