#### Hedgehog v2 — Gas Fee Hedging Architecture

**Hedgehog v2** introduces a **gas fee hedging architecture** designed for **account abstraction (AA) wallets, paymasters, and rollups** that need to stabilize gas exposure and operational costs in real time.\
Instead of relying on synthetic assets or complex delivery models, Hedgehog integrates **options and prediction markets** directly into the transaction lifecycle — allowing systems to **hedge**, **speculate**, or **lock in predictable gas costs**.

The result is a modular framework where **gas, MEV, and other on-chain costs** become **financially hedgeable variables**, enabling builders to create **cost-stable experiences** for users without abstracting away market efficiency.

#### 1. Core Actors & Components

* **AA Users** — Users interacting through Account Abstraction wallets who trigger on-chain transactions.
* **Bundler** — The node or service responsible for collecting, validating, and executing user operations.
* **EntryPoint** — The smart contract interface that validates and routes user operations.
* **Paymaster** — A smart contract that sponsors gas fees on behalf of users, enabling **gasless transactions**.
* **Options Market for Blockspace** — A permissionless marketplace where actors can buy or sell **options contracts** representing the future price of gas or priority fees.
