What is Solana rent?

On the Solana blockchain, rent isn’t a recurring fee but a minimum balance that accounts must hold to remain active. This balance, called the rent-exempt minimum, ensures efficient storage of account data across the network.

Think of it as a refundable deposit: as long as your account meets the minimum, it stays open. If you close the account, you get the deposit back.

How much is the rent-exempt minimum?

The amount depends on the type of account and its storage size. Examples include:

Basic SOL account: ~0.00089088 SOL (890,880 lamports)

Token account: ~0.00203928 SOL (165 bytes of data)

The rent-exempt minimum is calculated as two years’ worth of rent based on storage needs. Larger accounts, such as smart contracts, require more.

Note: In Wraith Wallet, the rent-exempt minimum is currently set to 0.001 SOL.

Why does Solana use rent?

Prevents spam: Discourages creating countless empty or abandoned accounts.

Supports validators: Compensates validators for storing account data.

Keeps things tidy: Stops leftover dust balances from clogging the system.

How does rent affect transactions?

You cannot leave less than the rent-exempt minimum in an account. For example:

If you hold 0.1 SOL and try sending 0.09969 SOL, you’ll get an error.

You must either leave the minimum (0.001 SOL) in the account or close it and transfer the full balance.

This ensures the blockchain doesn’t get clogged with unusable accounts.

Can you get the rent back?

Yes. If you no longer need an account:

Transfer out all SOL or tokens.

Close the account to reclaim the rent-exempt balance.

This process refunds the minimum deposit to you.

Final thoughts

Rent on Solana keeps the network efficient and secure by requiring a minimum balance for accounts. It ensures that every active account has enough resources to stay valid, while giving you full control over your funds.
