Bases: object

__init__(key, value)

Initializes a KVStoreData instance.

• Parameters:

  • key (str) – Key

  • value (str) – Value

class human_protocol_sdk.kvstore.kvstore_utils.KVStoreUtils

Bases: object

A utility class that provides additional KVStore-related functionalities.

static get(chain_id, address, key)

Gets the value of a key-value pair in the contract.

• Parameters:

  • chain_id (ChainId) – Network in which the KVStore data has been deployed

  • address (str) – The Ethereum address associated with the key-value pair

  • key (str) – The key of the key-value pair to get

• Return type:str

• Returns: The value of the key-value pair if it exists

• Example:

  from human_protocol_sdk.constants import ChainId
  from human_protocol_sdk.kvstore import KVStoreUtils
  
  chain_id = ChainId.POLYGON_AMOY
  address = '0x62dD51230A30401C455c8398d06F85e4EaB6309f'
  key = 'role'
  
  result = KVStoreUtils.get(chain_id, address, key)
  print(result)

static get_file_url_and_verify_hash(chain_id, address, key='url')

Gets the URL value of the given entity, and verify its hash.

• Parameters:

  • chain_id (ChainId) – Network in which the KVStore data has been deployed

  • address (str) – Address from which to get the URL value.

  • key (Optional[str]) – Configurable URL key. url by default.

• Return url: The URL value of the given address if exists, and the content is valid

• Example:

  from human_protocol_sdk.constants import ChainId
  from human_protocol_sdk.kvstore import KVStoreUtils
  
  chain_id = ChainId.POLYGON_AMOY
  address = '0x62dD51230A30401C455c8398d06F85e4EaB6309f'
  
  url = KVStoreUtils.get_file_url_and_verify_hash(chain_id, address)
  linkedin_url = KVStoreUtils.get_file_url_and_verify_hash(chain_id, address, 'linkedin_url')

• Return type:str

static get_kvstore_data(chain_id, address)

Returns the KVStore data for a given address.

• Parameters:

  • chain_id (ChainId) – Network in which the KVStore data has been deployed

  • address (str) – Address of the KVStore

• Return type:Optional[List[KVStoreData]]

• Returns: List of KVStore data

• Example:

  from human_protocol_sdk.constants import ChainId
  from human_protocol_sdk.kvstore import KVStoreUtils
  
  print(
      KVStoreUtils.get_kvstore_data(
          ChainId.POLYGON_AMOY,
          "0x15d34aaf54267db7d7c367839aaf71a00a2c6a65"
      )
  )

static get_public_key(chain_id, address)

Gets the public key of the given entity, and verify its hash.

• Parameters:

  • chain_id (ChainId) – Network in which the KVStore data has been deployed

  • address (str) – Address from which to get the public key.

• Return public_key: The public key of the given address if exists, and the content is valid

• Example:

  from human_protocol_sdk.constants import ChainId
  from human_protocol_sdk.kvstore import KVStoreUtils
  
  chain_id = ChainId.POLYGON_AMOY
  address = '0x62dD51230A30401C455c8398d06F85e4EaB6309f'
  
  public_key = KVStoreUtils.get_public_key(chain_id, address)

• Return type:str
