Implement Pause/Unpause

[Kaylahray]

User Story

• As an Admin, I want to pause the contract to stop attacks.

---

Description

• A global switch that prevents public actions when activated, effectively stopping any unwanted or malicious activity.

• ⚠️ This function must be strictly guarded and callable only by the stored Admin address.

---

Files to Create / Edit

• contracts/geev-core/src/
  • lib.rs

---

Functional Requirements

• Storage

  • is_paused (bool)

• Modifier / Check

  • Check is_paused at the start of every public function
  • Panic with error "ContractPaused" if true

• Admin Function: set_paused(env, val)

  • Require Admin authentication
  • Set Paused key to val

---

Suggested Implementation

• Function: set_paused(env, val)

  • Authenticate Admin
  • Write val to Paused key in storage

• Helper / Modifier: check_paused(env)

  • Read Paused key from storage
  • If true, panic!("ContractPaused")

---

Acceptance Criteria

• Public users cannot create or enter when paused
• Admin can still perform actions
