DeFi Yield Scanner
Autonomous scanner for DeFi yield opportunities across 10+ protocols.
What It Scans
- Aave v3 (Polygon, Arbitrum, Base): supply APY, borrow APY, utilization rate
- Compound v3: USDC/USDT supply rates, COMP reward APR
- Curve Finance: stable pools, CRV emissions, gauge weights
- Uniswap v3: fee tier APY for concentrated liquidity positions
- Yearn Finance: vault APY including harvesting strategy returns
Yield Ranking
Each opportunity is scored on:
- APY (raw + adjusted for token emissions)
- Risk (smart contract age, audit status, TVL)
- Sustainability (emission-adjusted vs organic APY)
- Gas efficiency (on Polygon/L2 vs mainnet)
How to Use
Ask: "Find the best stable yield on Polygon right now" or "Compare USDC yields across Aave, Compound, Curve"
The agent fetches live APY data, applies risk filters, and returns ranked opportunities with entry instructions.
Data Sources
- DeFiLlama API (
api.llama.fi) — TVL, APY, protocol metadata - Aave subgraph (The Graph)
- Curve registry (
curve.fi/api) - Yearn vaults API (
yearn.fi/api)
Output Format
Protocol | Pool | APY (base) | APY (rewards) | TVL | Risk | Rec
---------|---------------|------------|---------------|--------|-------|-----
Aave v3 | USDC (Polygon)| 2.71% | 0.00% | $841M | LOW | ✅
Curve | 3pool | 1.80% | 4.20% CRV | $432M | LOW | ✅
Yearn | USDC vault | 4.50% | 0.00% | $120M | MED | ⚠️
Usage Guidance
This skill appears coherent with its stated purpose and uses public DeFi APIs only, but review these points before installing: 1) Confirm you are comfortable with the agent making outbound network requests to the listed endpoints (api.llama.fi, curve.fi, yearn.fi, The Graph/Aave); 2) The SKILL.md is intentionally high-level — clarify whether the agent is permitted to execute transactions or request wallet signing (it currently does not ask for keys, and you should never supply private keys); 3) Expect no built-in authentication — some APIs may require rate-limited keys or return incomplete data under heavy use; 4) Treat recommendations as informational, not investment advice; test on small amounts or in a sandbox before acting on execution instructions; 5) If you need stronger controls, require the skill to explicitly list queries it will run and to never initiate on-chain transactions without explicit user confirmation.
Capability Analysis
Type: OpenClaw Skill
Name: defi-yield-scanner
Version: 1.0.0
The skill bundle contains standard metadata in `_meta.json` and a descriptive `SKILL.md` file. The markdown documentation clearly outlines the purpose of the DeFi yield scanner, its features, usage, and legitimate data sources (e.g., api.llama.fi, curve.fi/api, yearn.fi/api). There are no indications of prompt injection attempts, unauthorized commands, data exfiltration, or any other malicious or suspicious instructions targeting the AI agent or the underlying system.
Capability Assessment
Purpose & Capability
Name/description (DeFi yield scanner) align with the instructions: it pulls APY/TVL/metadata from public DeFi APIs (DeFiLlama, Curve, Yearn, The Graph/Aave). No unrelated binaries, creds, or config paths are requested.
Instruction Scope
SKILL.md is high-level: it instructs the agent to fetch live APY/TVL and apply risk filters and return entry instructions. It does not ask for private keys or local files, but is vague about exact queries, risk-data sources, or whether the agent should ever initiate on-chain transactions or request wallet signing. That vagueness grants the agent discretionary actions unless constrained by the platform.
Install Mechanism
Instruction-only skill with no install spec and no code files — nothing is written to disk and no external packages are pulled. This is the lowest install risk.
Credentials
The skill requires no environment variables, credentials, or config paths. This is proportionate for a read-only data-aggregation scanner using public APIs.
Persistence & Privilege
always is false and the skill does not request persistent privileges or modifications to other skills or system-wide settings. It can be invoked by the agent normally (default autonomous invocation), which is expected for a data-fetching skill.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install defi-yield-scanner - After installation, invoke the skill by name or use
/defi-yield-scanner - Provide required inputs per the skill's parameter spec and get structured output
