The repository implements Hipo, a decentralized liquid staking protocol on the TON blockchain. Users deposit GRAM to receive hGRAM tokens representing a share in a staking pool that lends to validators for validation rounds. Rewards increase the hGRAM/GRAM exchange rate, accruing value to stakers. The system features a modular smart contract architecture with upgradeable contracts (Treasury, Parent, Wallet, Loan, Bill, Collection, Librarian), a participation state machine tracking validation rounds, and a library management system for code reuse. It includes a comprehensive test suite with custom Jest matchers, deployment scripts, and diagnostic tools for monitoring state and analytics.
This repository provides an HTTP API service for interacting with the TON (The Open Network) blockchain. It acts as an intermediary, translating HTTP requests into calls to the TON blockchain via the tonlib library. The service is built with FastAPI and uses a pool of worker processes to communicate with TON nodes, handling load balancing and failover. It supports caching of responses via Redis to reduce load on the blockchain nodes. The service exposes both REST and JSON-RPC endpoints for a wide range of blockchain operations, including querying account information, executing smart contract methods, and sending transactions.
