# eth\_getStorageAt - Somnia

Example code for the eth\_getStorageAt JSON-RPC method. Complete guide on how to use eth\_getStorageAt JSON-RPC in GetBlock Web3 documentation.

This method returns the value from a storage position at a given address on the Somnia network. This is useful for reading raw contract storage, analyzing state, and debugging smart contracts.

| address     | string | Yes      | Contract address                 |
| position    | string | Yes      | Storage slot position (hex)      |
| blockNumber | string | Yes      | Block number in hex, or "latest" |
