A daily crypto, finance, and AI vocabulary grouping puzzle for beginners.
DeFi Yield Mechanics
These concepts help explain why DeFi yields move without making any price predictions.
Supply APYUtilization RateInterest Rate ModelYield Aggregator
- Supply APY: Supply APY is the estimated yearly return paid to lenders who supply assets to a lending market.
- Utilization Rate: Utilization rate is the fraction of supplied liquidity that is currently borrowed, often driving interest-rate changes in DeFi pools.
- Interest Rate Model: An interest rate model is a set of rules (often a curve) that maps utilization to borrow and supply rates in a lending protocol.
- Yield Aggregator: A yield aggregator is a protocol or strategy wrapper that routes capital across opportunities to optimize yield under its stated rules and risks.
Macro and Rates
These terms are common in macro discussions and help connect risk-free yields to broader financial conditions.
Policy RateDurationTerm PremiumInflation Expectations
- Policy Rate: A policy rate is a central bank's target interest rate that influences broader borrowing costs and risk-free yield benchmarks.
- Duration: Duration is a measure of how sensitive a bond's price is to changes in interest rates, with longer duration generally implying higher sensitivity.
- Term Premium: Term premium is the additional yield investors demand for holding longer-maturity bonds instead of rolling short-term debt, reflecting uncertainty over time.
- Inflation Expectations: Inflation expectations describe what households and markets believe inflation will be in the future, which can influence wages, prices, and interest rates.
AI Agent Building Blocks
These building blocks describe how an agent plans, uses tools, checks results, and stays within constraints.
- Tool Calling: Tool calling is when an AI model decides to invoke an external function or API (a tool) to fetch data or perform an action during a task.
- Planner: A planner breaks a goal into an ordered set of steps, sometimes delegating subtasks to specialized tools or modules.
- Retrieval: Retrieval is the process of selecting relevant documents or facts (often from a vector database or search index) to provide context before generation.
- Guardrails: Guardrails are constraints and checks that limit what an agent can do, such as tool permissions, content filters, or required validation steps.
On-Chain Monitoring
These concepts help describe how analysts monitor network activity and contract behavior without giving trading advice.
- Mempool: A mempool is the set of valid pending transactions waiting to be included in a block, which can be monitored for congestion and fee pressure.
- Event Logs: Event logs are records emitted by smart contracts that make it easier to track contract activity (like swaps or transfers) without scanning all internal state changes.
- Wallet Clustering: Wallet clustering is an analytics approach that groups addresses that may be controlled by the same entity using heuristics and activity patterns.
- Anomaly Detection: Anomaly detection is a set of methods for identifying unusual activity patterns, such as abnormal flows or contract interactions, for monitoring and risk review.
