# eth\_sign

{% hint style="warning" %}
The `eth_sign` JSON-RPC method is not supported because chainRPC doesn't store the user's private key required for the signature.
{% endhint %}

For more information about the method refer to the [official Ethereum wiki](https://eth.wiki/json-rpc/API#eth_sign).
