“Unstake” starts a process; it doesn't instantly put SOL back in your wallet.

Solana's documentation says native stake enters a deactivating state first. Changes complete at epoch boundaries, and network-wide limits can stretch the wait across more than one epoch. Withdrawals require the relevant stake to become inactive.

For $SOL holders, that delay matters if funds are needed on a deadline. Check the stake account's actual status rather than treating an epoch countdown as a guaranteed withdrawal time.
