Security measures that should be taken before running Nethermind Node on Ethereum Mainnet

Security

{% hint style="danger" %} 📢 DO NOT use Nethermind wallet / signers for mainnet ETH handling! {% endhint %}

{% hint style="danger" %} 📢 JSON RPC endpoint (port 8545) should NOT be exposed publicly (should be behind the firewall). {% endhint %}

{% hint style="danger" %} 📢The private key from which the node ID is derived is stored on disk (NOT protected by password). {% endhint %}

{% hint style="warning" %} Nethermind is thoroughly tested but the more popular it will get the more likely it will be the target of client-specific attacks. Generally you should always consider running backup client nodes implemented by a different team for any critical operations. {% endhint %}

{% hint style="info" %} For non-mainnet signing you can use dev wallet configurations. {% endhint %}
