6/6 — Your first transaction (with fake ETH) — Check your understanding
Key points
- Nonce collisions:What happens if two transactions use the same nonce? One replaces the other; only one can succeed.
- Confirmations:Why do more confirmations make a payment harder to reverse? Each new block builds on top, making rewrites increasingly costly and unlikely.
- Fees:Who receives the fee you pay, and why? The validator/miner who includes your tx; the fee is the incentive to process it.
- Explorer truth:Why trust an explorer over a wallet popup? It’s an independent view of the chain, not your local UI.
- Address check:What should you always verify before sending? First/last characters of the To address and the correct network.
