Balances Pallet

The Balances Pallet is a core module in the Polkadot SDK, responsible for managing token balances, enabling secure transfers, and supporting the blockchain’s economic operations. It provides robust mechanisms for balance management, transaction fees, and account lifecycle, ensuring a stable and efficient economic framework for Substrate-based blockchains.

Key functionalities:

• Account Balances Management: Maintains and tracks balances for all accounts, divided into free balance (spendable) and reserved balance (locked for specific purposes).

• Token Transfers: Enables secure token transfers between accounts with features like keep-alive transfers to prevent accounts from being reaped.

• Locks and Imbalances: Introduces runtime locks to temporarily restrict access to balances during specific operations (e.g., governance or staking) and handles imbalances through secure issuance or burning of tokens to maintain economic integrity across the system.
