Trading Strategy DeFi Yields is Now Live on SerenAI: Vault Performance Data for AI Agents

For DeFi Traders: Query 570+ yield vaults, 27 protocols, and 18 chains with real-time performance metrics—all at $0.01 per query. No subscriptions. No API keys. Just SQL.

Your AI agent can now answer: "Which stablecoin vaults on Arbitrum have the highest risk-adjusted returns over the past 3 months?" for about a penny.

The First Comprehensive Vault Performance Database for AI Agents

Until now, comparing DeFi yield strategies meant manually checking dozens of protocol dashboards, each with different metrics and timeframes. Trading Strategy DeFi Yields on SerenAI changes everything: AI agents can now query standardized performance data across 570+ vaults, comparing CAGR, Sharpe ratios, volatility, and fees in a single SQL query.

We're excited to announce that Trading Strategy DeFi Yields—a comprehensive vault performance database—is now available on the SerenAI x402 Gateway. AI agents can run SQL queries against real-time vault metrics including CAGR, Sharpe ratio, volatility, risk ratings, and fee structures, paying only for what they query via USDC micropayments on Base.

The Database

Trading Strategy DeFi Yields provides direct SQL access to institutional-grade vault performance data:

Real-Time Data for Fast-Moving Markets

DeFi yields change rapidly—a vault earning 30% APY today might drop to 10% tomorrow as liquidity shifts between protocols. Trading Strategy DeFi Yields updates every 6 hours to capture these dynamics, giving AI agents access to performance metrics that reflect current market conditions rather than stale historical snapshots.

This refresh frequency makes the database particularly valuable for:

• Yield optimization agents that need to rebalance positions as rates shift
• Risk monitoring systems tracking volatility and Sharpe ratio changes
• Trading strategy backtests requiring accurate historical performance data
• Portfolio analysis tools comparing cross-chain opportunities in real-time

Vault Data Fields

Each vault record includes comprehensive performance metrics:

• Performance: CAGR, 1-month returns, 3-month returns, lifetime returns
• Risk Metrics: Sharpe ratio, volatility, risk rating (numeric + label)
• Fees: Management fee, performance fee, deposit/withdraw fees
• Protocol Info: Protocol name, chain, denomination, share token
• Metadata: TVL (current NAV), event count, last updated timestamp
