Implementation

The HYRO Protocol implementation consists of a comprehensive Solana-based smart contract system, oracle infrastructure, and frontend interface. The current implementation focuses on Phase 0 foundation features with a modular architecture designed for future expansion.

Smart Contract Architecture

Core Programs

The protocol is built on Solana using the Anchor framework and consists of several interconnected programs:

Hyro Protocol (Main Program)

Program ID: 7gx2mxou2JwuBNiDhfPeXf8EVK8DUGnXPLKdiyYKT3NL
Contains the core vault system and transaction execution framework
Features modular design with optional components controlled by feature flags

Policy Programs All policy programs implement a unified validate function that handles multiple operation types (Creation, Execution, UseFunds, ReturnFunds) through operation-specific validation contexts. Available policy programs include:

policy_challenges: Challenge templates and participant management (9GbrovAKnWfbXuq5dXYiZgZob75qTBz9HFcZGFRjftcH)
policy_allow_any: Permits all transactions (2QPMdHH58BK9yFH5AdDmL4UXUb5hRBW51ga2p3KuUZ2t)
policy_deny_all: Blocks all transactions (2QPMdHH58BK9yFH5AdDmL4UXUb5hRBW51ga2p3KuUZ2t)
policy_limit_transfer: Enforces transfer limits
policy_owners: Restricts access to specific owners (G4wLdUkWJnqkN31sKA7t5RogsijrKryieVFaKuw1GvBL)

Vault System Implementation

Vault Account Structure

1pub struct Vault {
2    pub policy_account: Pubkey,
3    pub seed: String,
4    pub authority: Pubkey,
5    
6    // Manager fields (planned for future implementation)
7    pub manager: Option<Pubkey>,           // Assigned manager (if any)
8    pub parent_vault: Option<Pubkey>,      // Parent vault (if child)
9    pub allocation: u64,                   // Initial allocated amount
10    
11    // Balance tracking (planned for future implementation)
12    pub onchain_balance: u64,              // SOL/tokens in vault account
13    pub offchain_balance: u64,             // Funds in external venues (DEX, CEX, etc.)
14    pub total_balance: u64,                // onchain_balance + offchain_balance
15    pub last_balance_update: u64,          // Timestamp of last balance sync
16    
17    // Fee tracking (planned for future implementation)
18    pub high_water_mark: u64,              // For performance fees
19    pub total_fees_paid: u64,              // Audit trail
20    
21    // Manager fee structure (planned for future implementation)
22    pub manager_fees: Option<ManagerFeeStructure>,
23    
24    // Timestamps (planned for future implementation)
25    pub created_at: u64,
26    pub last_fee_collection: u64,
27}

Vaults are created using Program Derived Addresses (PDAs) with customizable seeds, ensuring unique and deterministic addresses. Each vault is associated with a specific policy program that governs transaction execution. The current implementation includes placeholder fields for future manager functionality.

Transaction System The vault system implements a multisig-like transaction execution pattern:

Transaction Creation: Users create transaction proposals with specific program calls
Policy Validation: The associated policy program validates the transaction using the unified validate function with operation-specific contexts
Execution: Approved transactions are executed by the vault authority

Transaction Account Structure

1pub struct Transaction {
2    pub nonce: u64,
3    pub did_execute: bool,
4    pub vault: Pubkey,
5    pub program_id: Pubkey,
6    pub data: Vec<u8>,
7    pub accounts: Vec<TransactionAccount>,
8}

Challenge System Implementation

Challenge Templates Challenge templates define the parameters for trading challenges, including:

Financial Parameters: Starting deposit, entrance cost, profit targets
Risk Management: Daily drawdown limits, maximum loss thresholds
Trading Requirements: Minimum trading days, maximum participants
Administrative: Admin controls, token mint for fees

Challenge Accounts Individual challenges track participant progress through:

Balance Tracking: Starting and current balance monitoring
Progress Metrics: Trading days completed, profit/loss calculations
Status Management: Challenge state transitions (initialized, active, completed, failed)
Payout Logic: Automated reward distribution upon completion

Oracle System Implementation

NATS-Based Architecture The oracle system uses NATS message queuing for reliable off-chain data processing:

Message Queue: NATS JetStream for persistent message delivery
Challenge Updates: Real-time trading performance data
On-Chain Integration: Automated blockchain updates based on off-chain events

Oracle Service Features

Template Discovery: Automatic discovery of managed challenge templates
Challenge Monitoring: Continuous monitoring of active challenges
Data Transformation: Conversion of off-chain data to on-chain format
Transaction Submission: Automated blockchain transaction execution

Frontend Implementation

Playground Application A comprehensive Next.js application provides:

Vault Management: Create and manage vaults with different policy types
Challenge Templates: Create and configure trading challenge parameters
Challenge Participation: Join challenges and track progress
Real-Time Updates: Live data fetching and display

TypeScript Client Generated using Codama for type-safe blockchain interactions:

Auto-Generated Types: Complete type definitions from Anchor IDLs
Instruction Builders: Type-safe transaction construction
Account Parsing: Automatic account data deserialization
Error Handling: Comprehensive error type definitions
