The Technology
The back-end infrastructure of the platform is built using Solidity, the object-oriented programming language for writing smart contracts on Ethereum-based platforms. We use Hard hat for the framework. Additionally, we use The Graph, a decentralized protocol for indexing and querying data from blockchains, to manage event indexing effectively. We use Chainlink as a system that provides secure and trustworthy information for self-operating programs, known as smart contracts, which work on various digital ledger systems.
