` - None if not configured - -### Modified Functions - -#### `schedule_upgrade(proposer, new_wasm_hash, proposal_id)` - -**Changes from previous version:** -- Now requires a valid proposal ID instead of just admin authorization -- Verifies the proposal was executed (approved by DAO) -- Verifies the proposer participated in the vote -- No longer requires admin role - any DAO voter can schedule - -**Parameters:** -- `proposer`: Address of a DAO participant who voted on the proposal -- `new_wasm_hash`: WASM hash of the new contract code -- `proposal_id`: ID of the executed governance proposal approving this upgrade - -**Validation:** -1. Governance contract must be configured -2. Proposal must exist and be in "executed" state -3. Proposer must have voted on this proposal -4. Proposer must authorize the transaction - -**Time-Lock:** 48 hours (172,800 seconds) before execution can occur - -#### `execute_upgrade(executor)` - -**Changes from previous version:** -- Can be called by anyone (not just admin) after time-lock -- Still requires contract to be paused for security -- Relies on governance approval done at scheduling stage - -**Parameters:** -- `executor`: Any address (typically the scheduler or admin) - -**Validation:** -1. Executor must authorize the transaction -2. Contract must be paused -3. Pending upgrade must exist -4. Time-lock period must have elapsed - -#### `cancel_upgrade(admin)` - -**No changes** - Remains admin-only for emergency cancellation - -### Constants - -```rust -UPGRADE_TIME_LOCK_SECS = 172800 // 48 hours -RESUME_TIME_DELAY = 86400 // 24 hours (for pause/resume) -``` - -## Security Considerations - -### Multi-Layer Security - -1. **Governance Approval**: Requires majority vote from token holders -2. **Time-Lock**: 48-hour delay allows community review -3. **Pause Requirement**: Contract must be paused during upgrade (emergency brake) -4. **Resume Delay**: 24-hour delay after pausing before resuming operations - -### Attack Mitigation - -- **Flash Loan Attacks**: Voting power based on staked tokens prevents flash loan manipulation -- **Rug Pulls**: Admin cannot unilaterally upgrade - requires DAO approval -- **Rushed Upgrades**: 48-hour time-lock ensures adequate review period -- **Malicious Execution**: Contract pause required, allowing community intervention - -## Usage Example - -### Step 1: Configure Governance Contract - -```rust -// Admin sets up governance integration -client.set_governance_contract( - &admin, - &governance_contract_address -); -``` - -### Step 2: Create Governance Proposal - -```rust -// In Governance contract: -let proposal_id = governance_client.create_proposal( - &proposer, - &upgrade_proposal_payload, // Contains new WASM hash - &start_time, - &end_time, -); -``` - -### Step 3: DAO Votes - -```rust -// Token holders vote on the proposal -governance_client.vote(&proposal_id, &voter, &true); // true = support upgrade -``` - -### Step 4: Finalize Proposal - -```rust -// After voting period ends -governance_client.finalize(&proposal_id); -// Proposal is now "executed" if it passed -``` - -### Step 5: Schedule Upgrade - -```rust -// Any voter can schedule the upgrade -project_launch_client.schedule_upgrade( - &voter_who_participated, - &new_wasm_hash, - &proposal_id, -); -``` - -### Step 6: Pause Contract - -```rust -// Wait for time-lock, then pause -project_launch_client.pause(&admin); -``` - -### Step 7: Execute Upgrade - -```rust -// After 48-hour time-lock -project_launch_client.execute_upgrade(&anyone); -``` - -### Step 8: Resume Operations - -```rust -// After 24-hour resume delay -project_launch_client.resume(&admin); -``` - -## Testing - -Comprehensive tests are included in `project-launch/src/lib.rs`: - -```bash -cd contracts -cargo test --package project-launch -``` - -**Test Coverage:** -- ✅ Setting governance contract -- ✅ Scheduling upgrade without governance fails -- ✅ Scheduling upgrade with invalid proposal fails -- ✅ Scheduling upgrade without voting participation fails -- ✅ Scheduling upgrade with valid proposal succeeds -- ✅ Executing upgrade before time-lock fails -- ✅ Executing upgrade without pause fails -- ✅ Executing upgrade after time-lock succeeds -- ✅ Cancelling upgrade clears pending state - -## Migration Path - -For existing deployments: - -1. **Current State**: Admin-controlled upgrades -2. **Transition**: Admin calls `set_governance_contract()` to enable governance control -3. **Future State**: All upgrades require DAO approval - -**Backward Compatibility**: If governance contract is not set, the contract can maintain backward compatibility mode (optional, based on implementation choice). - -## Integration with Other Contracts - -The same pattern can be applied to: - -- **Escrow Contract**: For milestone-based fund release logic upgrades -- **Profit Distribution**: For changing distribution algorithms -- **AMM Liquidity Pools**: For fee structure or formula updates - -Each contract should: -1. Add `GovernanceContract` storage key -2. Implement `set_governance_contract()` -3. Modify upgrade functions to require DAO approval -4. Add comprehensive tests - -## Audit Recommendations - -Before production deployment: - -1. **Third-Party Audit**: Engage a reputable smart contract audit firm -2. **Bug Bounty**: Launch a bug bounty program for the upgrade mechanism -3. **Community Review**: Allow sufficient time for community analysis -4. **Testnet Deployment**: Deploy and test on Stellar testnet first -5. **Gradual Rollout**: Start with non-critical contracts - -## Governance Best Practices - -### Proposal Content -Upgrade proposals should include: -- Detailed description of changes -- Security audit reports -- Test coverage summary -- Migration plan (if breaking changes) -- Rollback plan (if issues discovered) - -### Voting Period -Recommended minimum 7 days for upgrade proposals to ensure: -- Adequate community discussion -- Time for technical review -- Global participation across time zones - -### Quorum Requirements -Consider requiring higher quorum for upgrades (e.g., 20% of total supply) vs. regular proposals. - -## Conclusion - -This implementation ensures NovaFund contracts can evolve through decentralized governance while maintaining strong security guarantees. The multi-layer approach (governance approval + time-lock + pause mechanism) provides robust protection against malicious upgrades while enabling legitimate protocol improvements. - ---- - -**Document Version**: 1.0 -**Last Updated**: March 27, 2026 -**Author**: NovaFund Development Team + +Skip to content + +New chat +Agents +Spaces +Spark +Preview + +Copilot Chat +On-chain audit log for contract upgrades +You said: Create 'On-Chain Audit Log' for Contract Upgrades +Create 'On-Chain Audit Log' for Contract Upgrades +Copilot said: I'll help you create an 'On-Chain Audit + +I'll help you create an 'On-Chain Audit Log' for Contract Upgrades.
