Solana: Sending SOL in Python using Solders from a JSON file
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 using Solders
In this article, we will look at how to use Python’s Solders library to transfer all the SOL from different wallets in a .json file to a single target wallet.
Prerequisites
Before you begin, make sure you have the following installed:
- Python 3.6+
- Solder 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": "another 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 SOLs from different wallets to a single destination wallet:
import solders
def transfer_sols(wallets, destination_address):
"""
Transfers all SOLs 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 clientclient = solders.SoldersClient()
Load wallets from JSON filewallets_data = {}
with open('wallets.json', 'r') as f:
for f.readlines() line:
wallet_data = json.loads(row)
if wallet_data['address'] == destination_address:
wallets_data[destination_address] = wallet_data
Transfer SOL from all wallets to the destination addresswallet in wallets_data.values():
client.send_sols(wallet['balance'], wallet['label'])
Load wallets from JSON filewith open('wallets.json', 'r') as f:
wallets = json.loads(f.readlines())
Send SOL to a single destination walletdestination_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 from the “wallets.json” file into memory. We then iterate through all the wallets in the wallet list, check if they match the destination address, and use the send_sols
method to transfer the SOL from that wallet to the destination address.
Example Use Case
Let’s say you have two wallets with addresses 0x...
and 0x...
. You want to transfer all the SOL from these wallets to a single destination wallet, 0x...
.
You need to 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": "another test"
}
]
destination_address = '0x...'
transfer_sols(wallets, destination_address)
This will transfer all SOLs from the wallets to the destination address 0x…`.
Note that this function assumes that the wallets in the JSON file are already loaded and ready to use. If you need to manage a large number of wallets or complex wallet data, you may want to consider using a more efficient data structure or caching mechanism.
