Smart Contracts

Cocor Tech's flagship product Moistello is built on a suite of Rust/Soroban smart contracts deployed on the Stellar network.

Contract Architecture

Five contracts work together:

Circle Factory

Deploys new Circle instances and maintains a registry of all active circles. Handles circle creation and metadata storage.

Circle (Core Engine)

The per-circle contract that manages the ROSCA lifecycle. Handles member management, contribution tracking, payout distribution, and state transitions.

Treasury

Collects the 0.5% protocol fee on every payout distribution. Managed by protocol governance.

Reputation Registry

Calculates and stores on-chain MoiScore (0-1000) based on contribution history, streaks, completions, and volume.

Governance Token (MOI)

SEP-41 compliant governance token for DAO participation, protocol parameter changes, and fee structure updates.

Security

• Role-based access control (Admin, Organizer, Member)
• Checked arithmetic to prevent overflow/underflow
• Pause mechanism for emergency stops
• 45+ unit tests covering all contract functions
