The 52 editorial Q&A entries

The agent economy on Arc, mapped: every agent in the ERC-8004 identity registry that publishes a registration file (summary.registered and summary.withRegistrationFile carry both counts live; the registry grows, so no count is quoted here) with its name, what it does, the services it sells, its owner, its registration file and whether it accepts x402 payment — plus ?q= to search by capability ('audit', 'escrow', 'data').

The Agents Gift Shop — Designs created by the paying wallet (paid)

The answer key for Vaunt's live routes: every real-money news position of the last 14 days (closed 24h+ ago) with its cell, outcome, banded return and hold bucket, plus the weekly and per-strategy record. Check that what /opportunities showed 60 minutes after entry actually paid. Executed on Hyperliquid.

The answer, not the inputs. One call returns a stance for the coin — risk-on, risk-off, fragile or neutral — built from funding and open interest percentiles, sentiment, options implied volatility, the macro regime and what it costs to execute at your size. Every driver comes back with its number and its reading, plus the conditions that would invalidate the call. The rules are deterministic: the same market gives the same verdict.

The Arc pool graveyard, in full: every Uniswap v4 pool on Arc we measured above a lifetime volume floor (minVolumeUsdc), each with its pool id, its state (empty = zero liquidity at the moment of the read, or alive), its lifetime USDC volume, its fee and its hook. The counts live in summary (poolsMeasured, empty, alive, emptyPct, USDC volume through empty and live pools) and the time of the read in generatedAt.
