⏸️ Pausing Features on the LineaRollup, TokenBridge, and L2MessageService (with Pause Types)

This document outlines how a Safe Member can pause specific features on key Linea ecosystem contracts using well-defined pause types.

Note: These contracts are governed by the Security Council Charter.


🟧 Flow to Pause Features or Set Roles Allowed to Pause Types

Actor: Safe Member
Actions:

  • Selects a pause type from the list below
  • Adds a transaction via Security Council or Operational Safe
  • Targets the relevant Proxy
  • Calls the pauseByType() or updatePauseTypeRole() function with the selected values to unpause or set unpause type roles

Execution Path:

Safe Member
    → Security Council / Operational Safe
        → targets Proxy
            → calls pauseByType(type)
                → signs and executes on-chain

Verification Requirements:

  • Function and parameters must be verified
  • Transaction hash and simulation results must be confirmed

Note: Non-security council members are bound by cooldown period and timed expiry.
