Transaction Lifecycle

From signing to mining.

From Click to Confirmation

When you send a transaction, a lot happens behind the scenes before it becomes permanent.

This lesson walks through the full transaction lifecycle, from signing to inclusion in a block.

Your wallet assembles a transaction object containing the recipient, value, data, gas settings, and a nonce.

tx = {
  to:    0xRecipient...,
  value: 1000000000000000000, // 1 ETH
  nonce: 7,
  gasLimit: 21000,
  maxFeePerGas: 30 gwei
}
