longbridge-defi-yield

DeFi yield analysis framework — covers lending rates (AAVE / Compound), liquidity provision (LP) returns, staking yields, yield farming strategies, and risk-adjusted return comparison across DeFi protocols.

Response language: match the user's input language — Simplified Chinese / Traditional Chinese / English.

Data scope notice: Longbridge provides real-time spot prices for major cryptocurrencies (.HAS suffix, e.g. BTCUSD.HAS, ETHUSD.HAS). DeFi protocol metrics (APY, TVL, utilisation rates) are not available via the Longbridge CLI — they must be sourced via WebSearch (DefiLlama, CoinGecko, protocol dashboards).

When to use

Trigger when the user asks about:

• DeFi lending / borrowing rates — "AAVE 上 ETH 借贷利率", "Compound USDC supply APY"
• Liquidity mining / LP returns — "Uniswap LP 收益", "流动性挖矿策略"
• Staking yields — "ETH 质押收益率", "SOL staking APY"
• Yield farming strategies — "如何优化 DeFi 收益", "yield farming best strategy"
• Risk-adjusted DeFi comparison — "哪个协议收益最高且风险最低"

For crypto spot price only, prefer longbridge-quote. For general crypto market data, prefer longbridge-core.

Workflow

1. Identify asset and protocol from the prompt (e.g. ETH + AAVE, USDC + Compound).
2. Fetch spot price from Longbridge for the underlying crypto asset (as price reference):

   longbridge quote ETHUSD.HAS --format json
   

3. Fetch DeFi protocol data via WebSearch from canonical sources:
   • DefiLlama (defillama.com) for TVL, protocol APY, pool yields.
   • CoinGecko (coingecko.com) for staking yields and token data.
   • Protocol-native dashboards (app.aave.com, app.compound.finance) for live rates.
4. Compute risk-adjusted yield:
   • Nominal APY vs. inflation-adjusted real yield.
   • IL (impermanent loss) risk for LP positions.
   • Smart contract risk / audit status (note qualitatively).
5. Present comparison table across protocols/strategies, ranked by risk-adjusted return.

CLI

# Spot price for underlying crypto (price reference only)
longbridge quote BTCUSD.HAS --format json
longbridge quote ETHUSD.HAS --format json
longbridge quote SOLUSD.HAS --format json

Run longbridge quote --help to see supported .HAS crypto symbols.

DeFi protocol data is not available via the Longbridge CLI. Use WebSearch to retrieve live APY/TVL from DefiLlama, CoinGecko, or protocol dashboards.

command not found: longbridge	请先安装 longbridge-terminal（仅用于现货价格）	請先安裝 longbridge-terminal（僅用於現貨價格）	Install longbridge-terminal (for spot prices only)

MCP fallback

For spot crypto prices: the equivalent MCP tool with .HAS symbols. DeFi protocol data has no Longbridge MCP equivalent — WebSearch is required.
