Example: How to Send Signed Transactions to Besu RPC Nodes
|
||||
|
||||
This script demonstrates the correct way to send transactions to Besu,
|
||||
which requires eth_sendRawTransaction instead of eth_sendTransaction.
|
||||
|
||||
Usage:
|
||||
python3 example-send-signed-transaction.py <rpc_url> <private_key> <to_address> <amount_eth>
|
||||
|
||||
Example:
|
||||
python3 example-send-signed-transaction.py http://192.168.11.250:8545 0x<private_key> 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb 0.01
