Pool history
Daily price, total value locked, fees earned and in-range liquidity for 41 Uniswap v3 pools across Ethereum, Base and Arbitrum — 50,469 day-rows reaching back to 2021-05-05. Fees are the hard part. An indexer values a swap in dollars only if it can price both tokens, and each deployment keeps its own whitelist — so a pool can record thousands of trades in a day and report zero fees. Where the other side of the trade is a dollar, the fee is rebuilt exactly, and any row that was rebuilt is flagged. The tools pass that flag through. Read by LP strategies and backtesting a position.Options and volatility
Deribit’s volatility index (DVOL) back to 2021-03-24, plus option chains used to price structures at strikes away from the money. Read by option structures and pricing a hedge.Perpetual funding
Daily funding rates from Binance and Bybit, back to 2019-09 and 2021-01 respectively — about 2,080 days on each of BTC and ETH. They are kept separate and never averaged. The two correlate around 0.85 on BTC, and where they disagree the disagreement is the reading; a mean would hide exactly the days worth knowing about.Open interest
From Binance’s daily archive, at five-minute resolution since 2021-01-01: open interest in coins and in dollars, top-trader long/short by position size and by account count, and taker buy/sell volume.Coverage is per symbol, and the archive is walked one day-file at a time, so
a symbol can be partly filled while another is complete. Ask the tool for the
current depth rather than reading a figure here — it reports how many days it
holds, and that number moves.An absent or partial series is reported as such — never as a zero, because
an open interest of zero is a claim about the market and is never true.
Hyperliquid
A third venue, and it disagrees with the other two in ways that matter rather than ways that average out. Funding settles hourly — twenty-four intervals in a complete day, not three — and its history begins 2023-05-12, the venue’s own beginning. Its liquidations are richer than anything a centralised venue publishes: the address that was liquidated, the mark price at the time, whether it was taken at market or backstopped, and which vault absorbed it. Neither its open interest nor its liquidations can be backfilled — the venue reports open interest only as it is now, and its fills endpoint caps at 2,000 rows against vaults that trade constantly. So this stream records forward only, and begins when the watcher began. See Hyperliquid.Where every stream stops
A tool that cannot cover the window you asked for says so. None of them fills a
gap with a zero.
