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 (
.HASsuffix, 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
- Identify asset and protocol from the prompt (e.g. ETH + AAVE, USDC + Compound).
- Fetch spot price from Longbridge for the underlying crypto asset (as price reference):
longbridge quote ETHUSD.HAS --format json - 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.
- DefiLlama (
- 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).
- 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 --helpto see supported.HAScrypto symbols.
DeFi protocol data is not available via the Longbridge CLI. Use WebSearch to retrieve live APY/TVL from DefiLlama, CoinGecko, or protocol dashboards.

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