What Are Empty SPL Token Accounts?
Why ~0.002 SOL gets locked in token accounts when you receive tokens — and how closing vacant accounts returns it.
Each SPL token you receive creates an on-chain token account. Solana requires a minimum account balance (about 0.002 SOL) to keep that account open.
When you sell or transfer away the full balance, the account becomes empty but the SOL remains locked until you close the account.
Forager builds a CloseAccount transaction for empty SPL accounts that returns locked SOL to your wallet.
