🔐 Multi-signature Transaction Contract

[jobbykings]

Description: Implement advanced multi-signature transaction contract supporting complex approval workflows, time-based locks, and hierarchical signature requirements.

Requirements:

Hierarchical signature requirements
Time-based signature locks
Complex approval workflows
Signature revocation
Transaction batching
Emergency override mechanisms
Signature analytics
Cross-contract integration

Acceptance Criteria:
Hierarchical signatures (e.g., 2-of-3 for small amounts, 3-of-5 for large)
Time-locks prevent rushed approvals
Workflows support sequential and parallel approvals
Signatures can be revoked before execution
Batching reduces gas costs for multiple transactions
Emergency override requires super-majority
Analytics track signature patterns and delays
Integration works with all platform contracts
Gas optimization for multi-sig operations

Files to Modify:

Definition of Done:
Multi-sig system provides robust security controls
Hierarchical requirements scale with transaction risk
Workflow system supports complex approval processes
Security audit passes with no vulnerabilities
Gas optimization meets targets
Test coverage exceeds 95%
Documentation covers multi-sig workflows
Integration with all contracts works

@ScriptedBro has applied to work on this issue as part of the Stellar Wave Program's 3rd wave.

Hi, I am a full stack blockchain developer, and I’d like to apply for this issue.

I understand this requires building an advanced multi-signature contract with risk-based approval thresholds, time-lock protections, revocable signatures, batching, and complex sequential or parallel approval workflows. I can implement this in a secure and gas-conscious way, ensuring the approval model is flexible enough for real operational use while keeping execution, emergency overrides, analytics, and cross-contract integration reliable and well tested.

Thanks for your consideration.
