Snow

Nigel, your Web3 DeFi AI Companion on Telegram

Snow is a Telegram-based AI agent built to onboard DeFi newbies and help them make smart and safe investments in the Web3 world. Nigel—the personality behind Snow—runs on ElizaOS and leverages real-time market sentiment data from Chainlink to guide users through the AVAX C-Chain (starting with Fuji testnet).

Features

• Conversational AI: Nigel uses ElizaOS to assist users in a friendly and approachable way, directly via Telegram.
• DeFi Coach: Nigel suggests optimal liquidity pools based on market conditions, APY, and risk.
• Market-Aware: Integrates with Chainlink's Fear and Greed Index to assess sentiment and adjust strategies accordingly.
• Smart Contracts: Custom LP contracts on Fuji testnet simulate real DeFi investment environments.
• Autonomous Strategy: Nigel calculates the best pool and reallocates funds when market conditions change.
• Cross-Chain Ready: Architecture designed to scale to other chains using Chainlink CCIP and ICM.

How it Works

Nigel connects various decentralized components to provide intelligent, real-time investment advice:

1. Fetch Market Sentiment:

   • A Chainlink oracle fetches the Fear and Greed Index from off-chain data.
   • The index value is stored on-chain in a dedicated smart contract.

2. Analyze Pools:

   • Nigel considers a list of LP pools with:
     • APY (Annual Percentage Yield)
     • Risk Rating (1 for stable-stable, <1 for stable-alt)
   • Nigel dynamically adjusts preferences:
     • Greed (High Index): Boost preference for stable-stable pools.
     • Fear (Low Index): Boost preference for altcoin exposure.
     • Rising Index: Increase allocation to alts (FOMO behavior).
     • Falling Index: Shift toward stables (capital preservation).

3. Decision Making:

   • Nigel computes a weighted score per pool:

     Score = APY * Risk Ratio * Sentiment Adjustment
     

   • Funds are allocated to the pool with the highest score.
   • If market sentiment shifts, Nigel triggers rebalancing.

Chainlink Integration: Fear and Greed Index

A central feature of Snow is its use of the Fear and Greed Index, provided via Chainlink's decentralized oracle network:

• Nigel reads the current sentiment from an on-chain FearAndGreed contract, which gets updated via Chainlink feeds.
• The contract stores:
  • The latest index value (0–100)
  • A timestamp
  • Historical trend (to track rising/falling sentiment)

This sentiment directly influences investment logic:

• Low index (fear): Favor riskier assets with potential upside.
• High index (greed): Prefer safer, stable options.
• Trending Up: Nigel assumes FOMO and tilts toward alts.
• Trending Down: Nigel hedges in stables to preserve capital.

MVP Scope (Hackathon Deliverable)

In the 2-day hackathon, we focused on building a working MVP with:

• Telegram bot with ElizaOS integration (Olaf).
• On-chain Chainlink-powered Fear and Greed index (on Fuji).
• Two fake LP contracts with dummy APY and types (stable/stable vs stable/alt).
• Nigel’s decision-making logic that:
  • Reads the current index.
  • Calculates adjusted scores for each LP.
  • Invests in the best pool.
  • Rebalances when the index changes.

Future Plans

• Full Cross-Chain Deployment: Expand from Fuji to Ethereum Sepolia via Chainlink CCIP and other Avax L1 like Dexalot with ICM.
• Real LP Integration: Pull live APYs and risks from DeFi protocols.
• On-Chain Governance: Let users vote on Nigel’s behavior models.
• Portfolio Tracking: Telegram-based dashboard for holdings and performance.
• Auto-Staking: Let Nigel auto-stake/reinvest yields.

Tech Stack

• AI: ElizaOS
• Blockchain: Avalanche Fuji, Chainlink Oracles, Custom Solidity Contracts
• Telegram Bot: Node.js (Typescript)
• Chainlink CCIP & ICM: For cross-chain interactions (coming soon)
