Glossary / Solana Core
The smallest unit of SOL — 1 SOL equals 1,000,000,000 lamports. All Solana account balances and fees are stored as lamports.
A lamport is Solana's equivalent of a satoshi on Bitcoin: the smallest indivisible unit. One SOL equals exactly 1,000,000,000 lamports (1e9). Wallets and explorers display SOL for human readability, but on-chain everything is measured in lamports.
Named after Leslie Lamport, one of the pioneers of distributed systems research. When you see a transaction fee of ~5000 lamports, that is 0.000005 SOL.
The fastest way to internalize a term is to see it live on a Solana token you know. Paste any mint below to run a public Launch Score.
