Unified Governance and Security Contracts

[JosueBrenes]

Description

Create a comprehensive governance system to replace single admin controls across all TrustBridge contracts. Currently, all contracts use single admin addresses creating security risks and centralization issues. This implementation will add DAO governance, multisig controls, timelock mechanisms, and emergency procedures.

Current Security Issues

Single Points of Failure

• Oracle contract has single admin for price setting
• Pool Factory controlled by single admin
• Backstop contract admin controls all parameters
• No multisig or community governance

Missing Security Features

• No timelock for critical parameter changes
• No emergency pause mechanisms
• No governance voting for protocol upgrades
• Limited access control granularity

What to Implement

• Governor Contract for proposal-based governance
• Timelock Controller for delayed execution
• Multisig Factory for secure admin operations
• Emergency Pause system for crisis management
• Vote-Locked TBRG for governance power
• Treasury DAO for community funds

Acceptance Criteria

• All admin functions controlled by governance or multisig
• Critical changes require timelock delays
• TBRG holders can vote on proposals
• Emergency pause system functional
• Multisig controls for sensitive operations
• Treasury managed by community governance

Technical Requirements

New Contracts to Create

1. Governor Contract

   • Path: contracts/governor/
   • Purpose: Proposal creation, voting, and execution

2. Timelock Controller

   • Path: contracts/timelock-controller/
   • Purpose: Time-delayed execution of critical operations

3. Vote Escrow TBRG

   • Path: contracts/vote-escrow-tbrg/
   • Purpose: Time-locked TBRG for voting power

4. Multisig Factory

   • Path: contracts/multisig-factory/
   • Purpose: Deploy and manage multisig wallets

5. Emergency Controller

   • Path: contracts/emergency-controller/
   • Purpose: Emergency pause and recovery mechanisms

6. Treasury DAO

   • Path: contracts/treasury-dao/
   • Purpose: Community-controlled treasury management

Integration with Existing Contracts

Oracle Contract Governance Integration

impl Oracle {

        env: Env,
        timelock_controller: Address,

Pool Factory Governance Integration

// Update contracts/pool-factory/src/contract.rs
impl PoolFactory {
    /// Update pool implementation (governance controlled)
    pub fn update_pool_wasm(
        env: Env,

        emit_pool_wasm_updated(&env);
        Ok(())

Emergency Procedures

Emergency Controller Contract

// contracts/emergency-controller/src/contract.rs
#[contract]
pub struct EmergencyController;

#[contractimpl]
impl EmergencyController {
    /// Activate emergency mode (pause all contracts)
    pub fn activate_emergency(

        reason: String
    ) -> Result<(), EmergencyError> {
        guardian.require_auth();
        Self::require_guardian(&env, &guardian)?;

        // Pause all protocol contracts
        let contracts = Self::get_protocol_contracts(&env);
        for contract in contracts {
            env.invoke_contract(&contract, &Symbol::new(&env, "emergency_pause"), &());

        Self::require_governor(&env, &governor)?;

        // Unpause all protocol contracts
        let contracts = Self::get_protocol_contracts(&env);
        for contract in contracts {
            env.invoke_contract(&contract, &Symbol::new(&env, "unpause"), &());
        }

        env.storage().instance().set(&DataKey::EmergencyActive, &false);

}

Migration Strategy

Phase 1: Deploy Governance Contracts

1. Deploy Governor contract
2. Deploy Timelock Controller
3. Deploy Vote Escrow TBRG
4. Deploy Emergency Controller

Phase 2: Transfer Admin Rights

1. Transfer Oracle admin to Timelock Controller
2. Transfer Pool Factory admin to Timelock Controller
3. Transfer Backstop admin to Timelock Controller
4. Set Emergency Controller as guardian

Phase 3: Activate Governance

1. Initial TBRG distribution for governance
2. First governance proposals for parameter setting
3. Community onboarding and education

Security Considerations

Access Control

• Multi-signature requirements for critical functions
• Time delays for parameter changes
• Emergency pause mechanisms
• Role-based permissions

Economic Security

• Vote-locked TBRG prevents governance attacks
• Quorum requirements for proposal execution
• Proposal thresholds prevent spam

Testing Strategy

Governance Tests

#[test]
fn test_proposal_lifecycle() {
    let env = TestEnvironment::new();
    let contracts = deploy_governance_contracts(&env);

    // Test complete governance flow
    let proposal_id = create_test_proposal(&env, &contracts);
    vote_on_proposal(&env, &contracts, proposal_id);
    execute_proposal(&env, &contracts, proposal_id);

    assert!(proposal_executed_successfully());
}

Security Tests

#[test]
fn test_emergency_procedures() {
    let env = TestEnvironment::new();
    let contracts = deploy_all_contracts(&env);

    // Test emergency activation
    activate_emergency(&env, &contracts);
    assert!(all_contracts_paused());

    // Test governance recovery
    deactivate_emergency_via_governance(&env, &contracts);
    assert!(all_contracts_active());
}
