VestaLink

VestaLink is a blockchain‑based vesting and upkeep system that ensures transparent token release schedules. It integrates Solidity smart contracts with Chainlink price feeds and upkeep automation to solve the problem of manual, error‑prone vesting. By automating vesting conditions and linking them to external data, VestaLink provides a secure, reproducible workflow for token distribution.

The project is built with Solidity smart contracts, Hardhat for development and deployment, and TypeScript for testing. Chainlink’s MockV3Aggregator simulates price feeds, and upkeep logic ensures vesting conditions are automatically checked. The stack includes:

• Solidity (ERC‑20 + vesting logic)
• Hardhat (compile, test, deploy)
• TypeScript/JavaScript (tests + scripts)
• Chainlink MockV3Aggregator (price feed simulation)
• Chainlink Upkeep (automated vesting release conditions)
