Ethereum: Get all transactions from/to a Gnosis address
Tracking Ethereum Transactions from a gnosis address
=============================================== ==== =======
As you use the Tokentx Gnoza Scan API to take over the transaction data for an ERC-20 token, you may want to track all the coins that come and leave that address. In this article, we will explore how to achieve this.
Gnosos Scan API Reply Format
——————————
The Gnosis Scanning API returns a list of JSon Transactions. Each Transaction is represented as follows:
`Json
{
"tx_hash": "hash",
"Block_Number": 12345,
"From_address": "Address1",
"to_address": "Address2",
"Value": number (in wei),
"gases_price": number,
"Gas_used": number,
"Timestamp": Timestamp,
"Date": {
// Data Properties
}
}
tracking transactions from a gnoza address
-----------------------------------------------
To track all the movements of coins that come and move from a gnosis address, you can use the following steps:
- extract the transaction hashes : analyze the JSON response from the Gnoza Scan API and extract theTx_hash
Property, which contains the hexadecimal hash of each transaction.
- Store transactions in a database or cache : Store transactions extracted in a database (for example, sleblite) or a memory layer in cache (for example, redis). This will allow you to effectively recover all the transactions associated with the Gnoza Address.
- Use a data structure to track coins
: Create a Data Structure, Such which contains information on circulation currency.
Example Python Code
Python
Import sleqite3
Since Typing Import Dict
Configure the database connection
Conn = sleqite3.connect ('transaction_database.db')
Cursor = conn.cursor ()
Function for Extracting Transactions in the API Response
Def Get_transacti_Hashes (API_Response):
Return [tx_hash for tx_hash in api_response]
Function to Store Transactions in Database or Cache
Def store_transactions (transaction_hashes, db_name = 'transactions.db'):
with open (db_name, 'w') as f:
For tx_hash in transaction_hashes:
Enter the database or cache using a simple key value approach
Cursor.execut (in insert in transactions (tx_hash) values ({tx_hash} ')
Conn.commit ()
Function to track transactions from Gnoza Address
Def track_transactions
transaction_hashes = get_transction_hashes (api_response)
Store_transactions (transaction_hashes, db_name)
Example of Use:
API_Response = {{
"Result": [
{
"tx_hash": "0x1234567890ABCDEF",
"Block_Number": 12345,
"From_address": "Address1",
"to_address": "Address2"
},
{
"tx_hash": "0x23456789ABCDEF0",
"Block_Number": 67890,
"From_address": "Address3",
"To_address": "Address4"
}
]
}

benefits and considerations
-----------------------
- Thetx_hasha` property offers a unique identifier for each transaction.
- By historing transactions in a database or cache, you can effectively take over all the transactions associated with the Gnosis Address.
- This approach requirements some Aerial Data Structures for Transaction Storage and Management.
However, consider the following:
- The performance of the database or cache can be affected by the number of transactions.
- An additional storage space is required to store transaction.
- Make sure that they are in effect errors management mechanisms and proper exploitation.
