What happened to my transaction? Status, block, gas used, fee paid - and if it failed, the revert reason in plain text, recovered by replaying the call against its block. The receipt alone does not carry that reason.

Explain and preflight an unsigned Base transaction, EIP-712 typed data, or an EIP-3009 x402 payment authorization before you sign it. Decodes intent against verified ABIs, resolves proxies, classifies approvals, and checks a payment authorization against the quote it claims to pay: recipient, amount, asset, chain, freshness, and nonce replay. Returns unknown rather than guessing when a selector is ambiguous. Not a guarantee that a transaction is safe or profitable.

US Economic Release Calendar

US Energy Markets (Crude & Natural Gas)

US housing market snapshot in one call, live from FRED: housing starts, building permits, the Case-Shiller home price index with YoY change, and the 30-year fixed mortgage rate -- replaces 4 separate FRED series lookups. Not ticker-specific. $0.01/call.

US Housing Starts & Permits

US labor market snapshot in one call, live from FRED: nonfarm payrolls (level + MoM change), JOLTS job openings, average hourly earnings (YoY), and labor force participation rate -- the monthly labor picture that complements /jobless-claims' weekly initial/continuing claims. Replaces 4 separate FRED series lookups. Not ticker-specific. $0.01/call.

Key US macro indicators in one call, live from FRED: Fed funds rate, unemployment rate, CPI/core CPI/PCE inflation (YoY), real GDP growth (QoQ annualized), industrial production (YoY), retail sales (MoM), and consumer sentiment -- roughly 8 separate FRED series lookups collapsed into one request, with YoY/MoM math already done. Not ticker-specific. $0.01/call.

US money supply and bank credit snapshot in one call, live from FRED: M2 money stock (level + YoY change), M1 money stock, and commercial & industrial loan volume (level + YoY change) -- liquidity/credit-conditions indicators distinct from the price-level inflation series in /economic-indicators. Replaces 3 separate FRED series lookups. Not ticker-specific. $0.01/call.

US PCE Inflation (Fed's Preferred Gauge)

US Producer Price Index (PPI) in one call, live from FRED: headline Final Demand PPI and core PPI (ex food & energy), both YoY -- a leading inflation indicator that moves ahead of the consumer-side CPI/PCE already in /economic-indicators, since producer cost changes flow through to consumer prices with a lag. Not ticker-specific. $0.01/call.

US Treasury Yield Curve

US weekly jobless claims in one call, live from FRED: initial claims, continuing claims, and 4-week moving average of initial claims, with week-over-week change computed where available — a leading labor-market indicator that drives risk-off and day-trading directional calls. Replaces 3 separate FRED series lookups. Not ticker-specific. $0.01/call.

How close USDC lending on Base is to the kink where borrow rates explode: per-protocol utilization, the kink read from the protocol's own rate curve, headroom in bps, and borrow APY at points around it. Aave and Compound only — Morpho's adaptive IRM has no static curve and DefiLlama-sourced protocols expose none, so they are marked unmeasured, never assumed stable. Describes state, not a forecast. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.

Buyer-side MOVE/HOLD decision for USDC lending on Base: given your position (?position=), size (?amountUsd=), move cost (?moveCostUsd=) and horizon (?horizonDays=), returns whether moving to the best risk-adjusted protocol pays for itself — with expected net gain, break-even days and a confidence tier. Sells the decision, not the raw datapoint. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.

How long a USDC leadership call actually holds, from hourly on-chain attestations (EAS): median lead duration, survival at 6/24/72h, how much of the rotation is the same two protocols trading places, and what chasing the leader is worth per $10k before gas. Also reports whether a wider lead lasts longer — measured, and it does not. Observed history with sample sizes, never a forecast. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.

How much of the USDC lending APY on Base survives if incentives stop: per-protocol base-vs-reward split, the post-incentive floor, and whether the leader changes without incentives. Derived only from reported/inferred reward components already read — sources that do not itemize are listed as undecomposable, never assumed incentive-free. A stress test of current readings, not a date forecast. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.
