Each token account on Solana requires a small deposit of SOL (~0.002 SOL) to exist on the network. This deposit acts as "rent" for storing your account data.

When you receive new tokens, Solana creates token accounts to store them. Even after you've sold or transferred all tokens, these empty accounts remain with their rent deposits locked.

Each empty token account holds approximately 0.002 SOL. If you've interacted with many tokens, this can add up!

For example:
- 10 empty accounts ≈ 0.02 SOL
- 50 empty accounts ≈ 0.1 SOL
- 100 empty accounts ≈ 0.2 SOL

Solana has transaction size limits for stability. We process accounts in batches of 10 to ensure reliable transactions.
