This document outlines the governance process for upgrading smart contracts in the MyFans platform. Contract upgrades are critical operations that require careful planning, review, and execution to maintain platform security and user trust.
- Contract Owner: Primary authority for initiating upgrades
- Security Team: Must review and approve all upgrade proposals
- Technical Lead: Validates technical implementation and migration paths
- Document the reason for upgrade (bug fix, feature addition, optimization)
- Create detailed specification of changes
- Estimate impact on existing users and data
- Submit proposal for review
- Security audit of new contract code
- Peer review by at least 2 senior developers
- Impact analysis on frontend and backend integrations
- Test coverage verification (minimum 80%)
- Deploy to testnet environment
- Run full integration test suite
- Perform manual QA testing
- Execute migration dry-run with production-like data
- Security team sign-off
- Technical lead approval
- Product owner confirmation
- Document approval in upgrade log
- Schedule maintenance window
- Notify users of upcoming upgrade
- Execute upgrade on mainnet
- Verify upgrade success
- Monitor for 24 hours post-upgrade
- Upgrade proposal documented and approved
- Security audit completed with no critical findings
- All tests passing (unit, integration, e2e)
- Testnet deployment successful
- Migration scripts tested and verified
- Rollback plan documented
- User notification sent (48 hours advance)
- Backup of current contract state created
- Maintenance mode enabled
- Contract upgrade transaction executed
- Upgrade transaction confirmed
- Post-upgrade verification script run
- Critical functionality smoke tested
- All services operational
- User transactions processing normally
- No error spikes in monitoring
- Documentation updated
- Upgrade logged in changelog
- Post-mortem scheduled (if issues occurred)
For critical security vulnerabilities:
- Security team can fast-track approval
- Minimum 1 peer review required
- Testnet testing can be abbreviated but not skipped
- User notification can be reduced to 4 hours
- Post-upgrade monitoring extended to 72 hours
If critical issues are detected post-upgrade:
- Immediately enable maintenance mode
- Execute rollback to previous contract version
- Restore backed-up state if necessary
- Notify users of rollback
- Conduct incident post-mortem
- Document lessons learned
All upgrade decisions must be logged in docs/upgrade-log.md with:
- Date and time
- Contract name and version
- Approvers
- Reason for upgrade
- Outcome
For upgrade-related questions:
- Security: security@myfans.platform
- Technical: tech-lead@myfans.platform
