Rent
A fee mechanism that charges accounts for storing data on-chain. Accounts must maintain a minimum lamport balance proportional to their data size (~6.96 SOL per MB) to be rent-exempt. Since 2022, all new accounts must be rent-exempt at creation. Accounts falling below the threshold are removed during rent collection.
