SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

VaraCore solves the fragmentation of agent infrastructure on the Vara Network by providing a unified, on-chain source for asset pricing, agent reputation, and capability discovery.

Core Features & Use Cases

  • OracleService: Provides multi-asset price feeds (VARA, BTC, ETH, DOT, USDT) with outlier rejection and TWAP-based manipulation resistance.
  • ReputationService: Calculates on-chain trust scores (0-1000) for agents based on success rates, interaction volume, and tenure.
  • AgentRegistry: Enables capability-aware discovery of autonomous agents, allowing developers to find and integrate specialized services like DeFi or governance participants.

Quick Start

Use the VaraCore skill to query the current BTC/USD price from the mainnet program by sending a SCALE-encoded request to the Oracle service.

FAQPage Schema
How do I get reliable price feeds for autonomous agents on Vara Network?

To get reliable price feeds for autonomous agents on Vara Network, query the VaraCore OracleService. It provides multi-asset pricing for VARA, BTC, ETH, DOT, and USDT using outlier rejection and TWAP-based smoothing to resist price manipulation.

What is on-chain agent reputation scoring and how does it work?

On-chain agent reputation scoring calculates a 0-1000 trust score for decentralized agents using the VaraCore ReputationService. It dynamically evaluates agent success rates, interaction volume, and tenure to establish reliable trust metrics for autonomous interactions.

How do I query BTC/USD prices from a Vara Network mainnet program?

To query BTC/USD prices from a Vara Network mainnet program, send a SCALE-encoded request to the VaraCore Oracle service address. This centralizes access to validated, manipulation-resistant price feeds for your decentralized application.

How do autonomous agents discover service capabilities on blockchain networks?

Autonomous agents discover service capabilities on blockchain networks using the VaraCore AgentRegistry. This registry enables capability-aware discovery, allowing developers to find and integrate specialized decentralized services like DeFi or governance participants.

Can I access oracle, reputation, and registry services at a single program address?

Yes, you can access oracle, reputation, and registry services at a single program address using VaraCore. This composable on-chain infrastructure eliminates fragmentation by centralizing agent data validation, trust scoring, and discovery operations.

What are the limitations of using TWAP-based price smoothing for blockchain oracles?

The limitation of TWAP-based price smoothing for blockchain oracles is that it relies on historical data averages, which may lag during sudden market volatility. VaraCore mitigates this with outlier rejection to ensure secure decentralized operations.
