Glossary / Solana Core
A set of Solana validators running the same version of the ledger — usually mainnet-beta, devnet, or testnet.
A Solana cluster is a network of validators sharing a ledger. Mainnet-beta is the production chain where real SOL and real tokens live. Devnet is a public sandbox with free SOL from faucets. Testnet is used by validators to test upgrades.
When a wallet or tool asks which cluster you are on, it means which RPC endpoint you are connected to. MakeMeACoin operates on mainnet-beta.
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.
