Educational films about native Solana units and network mechanics.
A native lamport is a denomination of SOL, separate from the LAMPORT project token.
A native lamport is the smallest unit of SOL. One SOL contains one billion lamports. Solana records native balances as whole-number counts of these units. That makes a lamport a denomination of SOL. The separate LAMPORT project token is a different asset. This conversion is not an exchange-rate peg for that token.
Base fees are charged per signature. An optional priority fee can change the total.
When you send a Solana transaction, fees are paid in SOL. The current base fee is five thousand lamports per signature. An optional priority fee can add to the total and improve scheduling priority. So five thousand lamports is not a fixed total for every transaction. Check the fee estimate before sending. Fees can still apply when execution fails.
Decimal SOL amounts become exact whole-number lamport amounts in payment code.
Small units make precise amounts easier to work with. On Solana, zero point zero one SOL equals ten million native lamports. A payment can be shown in SOL while code uses a whole-number lamport amount. Keep the transfer amount and transaction fee separate. Clear units help people and programs agree on exactly what is being sent.
