🕰️ Timeleap Subnet Staking Contracts

This repository contains the staking logic used in the Timeleap Network, enabling participants to stake ERC-20 tokens with defined durations and withdrawal conditions. The system is built with modularity and upgradeability in mind, supporting safe and flexible future enhancements. Refer to TEP-5 for more information.

⚙️ Architecture Overview

The staking system is composed of multiple contracts:

• Manager: Coordinates staking, slashing, and withdrawals.
• Stakes: Maintains stake records and lock durations.
• Bank: Handles token custody and transfers.
• Repository: Tracks the latest Manager contract deployed.

By distributing responsibilities across specialized contracts, the system ensures that upgrades to logic can be performed safely without risking data or funds.

🔁 Upgrade Pattern

The architecture follows a separation-of-concerns pattern to maximize safety and flexibility:

• Data and tokens are never stored in the Manager contract. Instead, they are handled by dedicated contracts (Stakes and Bank) which remain untouched during logic upgrades.
• The Manager contract contains only logic and can be redeployed as needed to introduce new functionality or fix issues.
• The Repository contract serves as a pointer to the currently active Manager contract, allowing frontends and other contracts to reference the latest logic without requiring migrations or manual updates.

This pattern ensures that:

• User funds are always secure and unaffected by upgrades.
• Upgrades do not require interrupting the staking process.
• The system remains extensible and maintainable over time.

📦 Dependencies

• OpenZeppelin Contracts v5.x
• Solidity ^0.8.28
