TimeLock is a decentralized time-based escrow protocol built on blockchain technology that allows users to lock digital assets for a specified period of time. The protocol enables secure, trustless time-locked transfers where tokens can only be released to the recipient after a predefined unlock time.
TimeLock aims to revolutionize the way digital assets are securely transferred with time constraints. By leveraging blockchain's immutability and transparency, we create a trust-minimized escrow system that eliminates intermediaries and reduces counterparty risk. The protocol enables use cases ranging from vesting contracts and delayed payments to crowdfunding with milestone-based releases, ultimately making time-based asset transfers more accessible, efficient, and secure for everyone.
- Time-Locked Escrow: Lock ERC20 tokens for a specified time period
- Secure Token Management: Smart contract architecture ensures tokens can only be released after the unlock time
- Flexible Recipient Management: Lock tokens to be released to specific recipients
- Governance System: Contract parameters managed through decentralized governance
- Transparent Execution: All actions are recorded on-chain with comprehensive events
- Low Gas Optimization: Efficiently designed for minimal gas consumption
TimeLock is built with a dual-layer architecture:
-
Smart Contract Layer: Solidity contracts deployed on Ethereum (or compatible EVMs)
TimeLock.sol: Core escrow functionality handling token locking and release- Utilizes OpenZeppelin libraries for security best practices
-
Client Interface Layer: Rust-based client for interacting with the protocol
- Abstracts away blockchain complexities
- Provides a simple, developer-friendly API
- Implements robust error handling and transaction management
-
