And same for "serialize", what is it. When private key is not handled by any third party like Metamask, we need to perform serialization before sending. I'm converting Json object with transaction data to hex string, concatenating it with private key data converted to hex string and then calculating keccak hash.

And then I push this data to sendRawTransaction. But something is wrong Jun 3, at 1 Well, I found a reason why it doesn't work - a raw transaction must be encoded to RLP format. It requires nonce, gasPrice, gasLimit, recipientAddress, amount, comment, r, s, v fields in that order. I've read RLP documentation and follow it during transaction creation, but now I'm getting an error "rlp: input string too long for common. Types of transactions On Ethereum there are a few different types of transactions: Regular transactions: a transaction from one account to another.

Contract deployment transactions: a transaction without a 'to' address, where the data field is used for the contract code. Execution of a contract: a transaction that interacts with a deployed smart contract. In this case, 'to' address is the smart contract address.

On gas As mentioned, transactions cost gas to execute. Simple transfer transactions require units of Gas. Diagram adapted from Ethereum EVM illustrated Any gas not used in a transaction is refunded to the user account. Transaction lifecycle Once the transaction has been submitted the following happens: Once you send a transaction, cryptography generates a transaction hash: 0x97d99bca21b12ccd4ff1dffdff The transaction is then broadcast to the network and included in a pool with lots of other transactions.

A validator must pick your transaction and include it in a block in order to verify the transaction and consider it "successful". As time passes the block containing your transaction will be upgraded to "justified" then "finalized". These upgrades make it much more certain that your transaction was successful and will never be altered.

Once a block is "finalized" it could only ever be changed by an attack that would cost many billions of dollars. A visual demo Watch Austin walk you through transactions, gas, and mining. Typed Transaction Envelope Ethereum originally had one format for transactions. Each transaction contained a nonce, gas price, gas limit, to address, value, data, v, r, and s. These fields are RLP-encoded, to look something like this: RLP [nonce, gasPrice, gasLimit, to, value, data, v, r, s] Ethereum has evolved to support multiple types of transactions to allow for new features such as access lists and EIP to be implemented without affecting legacy transaction formats.

EIP Typed Transaction Envelope defines a transaction type that is an envelope for future transaction types.
