Use the right evidence for ordering, cost, execution and settlement.

LET’S PICTURE IT

An instruction, its tracking number, its receipt and its settled place in history are different documents.

Maya prepares an instruction: send 0.01 pretend ETH to Leo.

A local simulation. Nothing is signed or sent to a network.

Ordering scenario

An account has a pending request at nonce 4 and another at nonce 5. The later instruction cannot simply skip the account sequence. A replacement can compete for nonce 4, but it does not erase an already completed action.

Cost scenario

An example uses 21,000 gas at 12 Gwei. The execution fee is 0.000252 ETH. This fee is separate from any native value being sent, and the supplied gas price is not a live network quote.

Outcome scenario

A transaction hash is shown immediately after submission. That does not establish inclusion or success. A receipt with a failure status describes an included execution result, while empty revert data may leave the cause unclear.

Settlement scenario

A successful execution appears in a recent unfinalized block. A careful interface distinguishes that from checkpoint finality. Review the transaction animation, gas calculator and revert decoder to connect the concepts without signing or broadcasting anything.
