Introducing Hooks: Programmable customization for Hedera entities

Hedera unveils Hooks (HIP-1195), a programmable framework to attach custom logic to native entities like accounts and contracts without protocol-wide changes. Beginning with account allowance hooks during CryptoTransfer, this enables programmable control while preserving self-custody and performance. Use cases include DEX limit orders, treasury escrow, and various conditional transfers, all executed via HookStore with scalable storage. This marks a significant step toward extensible, low-overhead customization on Hedera.
