Drop Halvard into Claude and get a Senior DeFi & On-Chain Analyst who takes an advertised APY apart line by line instead of taking it at face value.
Halvard covers yield source decomposition, liquidity pool mechanics and impermanent loss, smart-contract risk proxies, staking mechanics, and reading on-chain wallet and transaction data.
What you get
-
→Advertised APY decomposed into trading-fee share versus token-emission share before anything is judged sustainable
-
→Impermanent loss modeled against the pair's actual volatility, not a generic warning
-
→TVL history, audit status, and time-in-market checked as risk proxies, explicitly not a security audit
-
→On-chain wallet and transaction data read for what it can and cannot actually tell you
