Decoding of safe events from Ethereum web3.py
Ethereum’s decentralized funding (defi) ecosystem is strongly dependent on intelligent contracts to facilitate safe and open transactions. One of the most common cases is the Multisig wallet, which allows many users to share one wallet and authorize events without having to accept each individual event manually.
When a safe event takes place, it includes sending funds from one Multisig wallet to another. However, due to the decentralized nature of Ethereum Blockchain, transaction data cannot be decoded or terminated from the agreement with ABI (abstract syntax) without proper understanding and tools.
In this article, we are looking at how to unpack safe event data from the Etheruma Python Library with WEB3PY, which provides a simple and intuitive application interface interacting with the Ethereum block chain.
What is safe event information?
Safe transaction information refers to every metadata related to the event. In Ethereum, the agreement ABI (abstract syntax) defines the structure and behavior of an intelligent contract. However, when the Multisig wallet sends funds from one address to another, the event information itself does not contain the necessary information to dismantle it directly.
Understanding the information of safe events
Safe transaction data typically contain fields such as:
txhash: the hexadecimal seal of the event
Blocknumbber: block number where the event took place
FROM: Sender Address
To: The address of the recipient
- “Value”: The amount of ether to be moved
Gasprice: The price of gas used to complete the trade
Web3py and Safe Event Information
To dismantle safe event data, the Web3PY application interface interacts with the Ethereum block chain. First, make sure you have the latest Web3PY version installed:
`Bash
PIP to install web3
`
Let’s now create a simple script that disassembles the safe event of the txhash field:
`Python
Web3 Import Web3
Start web3
w3 = web3 (web3.httpprovider (‘
Specify Safe Event Information
tx_hash = ‘0x6a761202’
replaces with real TXHAS field
try:
Get an event object from the blockchain
tx = w3.eth.gettransaction (tx_hash)
Print unloaded transaction data
Print (‘Event Information:’)
Print (f’xhash: {tx_hash} ‘)
Print (F’blocknumber: {tx.blocknumbber} ‘)
Print (F’Sender: {tx.from} ‘)
Print (F’receiver: {tx.to} ‘)
Print (F’Money Sent: {tx.valu} ether ‘)
Print (F’Gas price: $ {tx.gasprice} ‘)
Except the exception as E:
Print (f’error: {e} ‘)
`
In this example, we use the “eth.gettransaction” method to retrieve a transaction object associated with a safe event. Then we use different fields of event data.
Demolition of long six queues
If you have a long six -queue starting from 0x6A761202, you can use the Web3PY “Fromhex” to dismantle it:
`Python
Long_hex_string = ‘0x6A761202’
Replace with a real six queue
try:
tx_data = w3.eth.fromhex (long_hex_string)
Print (TX_Data)
Print Disassembled Transaction Information
Except the exception as E:
Print (f’error: {e} ‘)
`
This produces the txhash field, which you can then use again to dismantle safe events.
conclusion
In this article, we have shown how web3PY can be used to dismantle and disassemble Ethereum’s safe event data. By utilizing the library’s application interface and understanding of intelligent contract information structures, you can effectively dismantle complex metadata of events without calling for manual approvals or direct access to the contract Abbi.
