Unifra does not store keys, so transactions sent via Unifra must be signed ahead of time using another provider like ethers (via eth_signTransaction) and sent with eth_sendRawTransaction.\

NOTE: Writing data on Optimism is handled by its sequencers; for more information on specifics, please refer to the Optimism docs.

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.

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.
