eth_sendRawTransaction
Creates a new message call transaction or a contract creation for signed transactions.
Alchemy does not store keys, so transactions sent via Alchemy must be signed ahead of time using another provider like ethers (via eth_signTransaction) and sent with eth_sendRawTransaction.

Parameters

DATA, The signed transaction data.

params: ["0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675"]

Returns

DATA, 32 Bytes - the transaction hash, or the zero hash if the transaction is not yet available.
Use eth_getTransactionReceipt to get the contract address after the transaction was mined when you created a contract.
Example
Note: Since eth_sendRawTransaction is a request used for writing to the blockchain and changes its state, it is impossible to execute the same request twice. This means if you were to copy the example given below you will not get the expected response.
