I can't execute a send transaction method of my smart contract from the frontend by Alchemy
I am a beginner and I am trying to execute a method from my frontend that sends a transaction to the blockchain but I get an error from alchemy saying that the transaction needs to be signed with my private key but I have no idea how to do this and I did not find anything similar In Internet
Error in the front: Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'transactionHash')
Error in Alchemy: Unsupported method: eth_sendTransaction. Alchemy does not hold users' private keys. See available methods at https://docs.alchemy.com/alchemy/documentation/apis
Error in Alchemy: {
"jsonrpc": "2.0",
"error": {
"code": -32600,
"message": "Unsupported method: eth_sendTransaction. Alchemy does not hold users' private keys. See available methods at https://docs.alchemy.com/alchemy/documentation/apis"
},
