Here is an article on how to send SOL from a JSON file using the Solders library and Python:

Sending SOL from a JSON file with Solders

In this article, we will explore how to use the Python library Solders to transfer all SOL from different wallets contained in a .json file to a single target wallet.

Prerequisites

Before we begin, make sure you have the following installed.

• Python 3.6+

• Solders library (“pip install solders”)

• Wallet JSON file named “wallets.json”.

Wallet JSON File Structure

The wallet JSON file should be structured as follows:

[
{
"address": "0x...",
"balance": 1000,
"tag": "test"
},
{
"address": "0x...",
"balance": 500,
"tag": "other test"
}
]

In this example, we have two wallets with addresses “0x…” and balances of 1000 and 500 respectively. The “tag” property is used to identify the wallet.

Python function

Here is a Python function that transfers all SOL from different wallets to a single destination wallet:

import solders
def transfer_sols(wallets, destination_address):
"""
Transfers all SOL from different wallets to a single destination wallet.
Parameters:
wallets(list): list of wallet dictionaries
destination_address(str): destination address of the transferred SOL
Returns:
None
"""





Create a Solders client
client = solders.SoldersClient()

Load wallets from a JSON file
wallets_data = {}
with open('wallets.json', 'r') as f:
for line f.readlines():
wallet_data = json.loads(line)
if wallet_data['address'] == destination_address:
wallet_data[destination_address] = wallet_data

Transfer SOL from each wallet to the destination address
to the wallet in the file wallets_data.values():
client.send_sols(wallet['balance'], wallet['tag'])

Load wallets from JSON file
with open('wallets.json', 'r') as f:
wallets = json.loads(f.readlines())

Send SOL to one destination wallet
destination_address = '0x...'
transfer_sols(wallets, destination_address)
print ("SOL transferred successfully!")

Explanation

In this example, we first create a Solders client and load the wallets from the file “wallets.json” into memory. We then iterate over each wallet in the wallet list, check if it matches the destination address, and transfer SOL from that wallet to the destination address using the “send_sols” method.

Example use case

Let’s say you have two wallets with addresses “0x…” and “0x…”. You want to transfer all SOL from these wallets to a single destination wallet “0x…”.

Create a list of wallet dictionaries, load them into memory using the Solders client, and then call the “transfer_sols” function:

wallets = [
{
"address": "0x...",
"balance": 1000,
"tag": "test"
},
{
"address": "0x...",
"balance": 500,
"tag": "other test"
}
]
destination_address = '0x...'
transfer_sols(wallets, destination_address)

This will transfer all SOL from the wallets to the destination address 0x....

Note that this function assumes that the wallets in the JSON file are already loaded and available for use. If you need to process a large number of wallets or complex wallet data, you may want to consider using a more efficient data structure or caching mechanism.
