offchain_localStorageGet - JSON-RPC Method

Description#

Reads a value from the offchain worker local storage of the queried node. Offchain workers can persist data in either persistent or temporary storage; this RPC lets operators debug that state. Because it exposes node-local data, the method is typically available only on trusted endpoints.

Parameters#

ParameterTypeRequiredDescription
kindstringYesStorage kind ("PERSISTENT" or "LOCAL")
keystringYesHex-encoded key

Request Example#

{
  "jsonrpc": "2.0",
  "method": "offchain_localStorageGet",
  "params": [
    "PERSISTENT",
    "0x6d795f6f6666636861696e5f6b6579"
  ],
  "id": 1
}

Response Example#

{
  "jsonrpc": "2.0",
  "result": null,
  "id": 1
}

A non-null result is a hex-encoded SCALE value written by an offchain worker.

Notes#

  • This RPC surfaces node-local data; public API providers often disable it for security.
  • Use "LOCAL" to read ephemeral values stored for the current block.
  • Pair with offchain_localStorageSet on validator tooling for smoke tests.
