feat(usd): price every trade and fee at the time it happened by kevincodex1 · Pull Request #133 · Twigpine/openlaunch

kevincodex1 · 2026-11-10T15:04:38Z

Summary

The all-time volume ($11.7M), the fee totals and each token's USD volume priced every trade ever made at today's quote price (queries.getLaunchTotals: quote volume × live price). So September trades moved with today's ETH and GITLAWB, and both sit near their lows since launch (ETH $2,063–$2,784, GITLAWB 6.2e-6 to 7.5e-5). This PR records each trade's USD value at its own hour. Nothing visible changes yet: a follow-up switches the site to these values after the backfill.

bb_quote_usd_hourly: one USD price per quote per UTC hour. The indexer writes the live price into the hour in progress (usdLedger.captureLiveUsd: at most once a minute per chain, always on a new hour, same sources as the lists, never throws).
usd on every trade and quote-side fee, at its own hour, written in the event's own transaction, plus running sums bb_launches.volume_usd / fees_collected_usd / fees_burned_usd. No price for that hour means NULL, never a guess.
scripts/usd-backfill.ts writes one reviewed SQL file; it never touches a database itself.
- Hourly history since launch: Coinbase for ETH and HYPE (Hyperliquid fills HYPE gaps); GeckoTerminal for GITLAWB (its WETH pool price × ETH-USD, the live method); TWIG = GITLAWB; stables $1.
- --mode dry-run prints old vs trade-time per chain and quote, then rolls back.
- --mode apply writes, then recomputes totals under the rebuild-launch-totals.sql locks.
- It never replaces a live-captured hour and stops at the last completed hour.
LAUNCH.md: the runbook.

Points scoring is unchanged this season. Stocks, community pairs and unlisted quotes have no price history: their older trades stay unpriced and count as partial.

Test plan

tsc, lint clean; npm test: 1404 tests, 1393 pass, 0 fail. New: usd-history.test.ts (hours, parsers, gap fill, quote→series mapping, generated SQL for both modes, the indexer's same-transaction pricing).
Throwaway Postgres 16:
- the real migrate.mjs applies on a fresh database and again unchanged
- fixture launches (ETH, Arc USDC, GITLAWB, unlisted) with trades and fees
- the dry run reported the hand-computed values and left the database untouched
- apply wrote exactly those values, kept the live-captured hour, and left the unlisted trade and the token-side burn NULL
- a second apply changed nothing
Real captureLiveUsd through the real driver: a live 2-ETH trade priced at exactly 2 × the captured spot, and the launch total moved by that amount.
The backfilled GITLAWB and ETH for the latest hour match the live site within 1%.

Summary by CodeRabbit

New Features
- Launch swaps and eligible fees now include USD values based on the quote’s price at the event time. Events without an available price remain unvalued, and contribute zero to launch totals.
- Launch totals now track USD trading volume and fees collected or burned.
Documentation
- Added instructions for generating and applying a historical USD price backfill, including a dry-run option. Older trades using unsupported quote currencies may remain without USD values.

The all-time volume (and the fee and per-launch USD figures) priced every trade ever made at TODAY's quote price: queries.getLaunchTotals summed each quote's volume times its live price. So September trades moved with today's ETH and GITLAWB. Both sit near their lows since launch (ETH $2,063..$2,784, GITLAWB 6.2e-6..7.5e-5), so the figure was understated. This change records each trade's USD value at its own hour. The site still reads the old figures until a second change switches it, after the backfill below. - bb_quote_usd_hourly: one USD price per quote per UTC hour. The indexer writes the live price into the hour in progress (usdLedger.captureLiveUsd: at most once a minute per chain, always on a new hour, same sources as the lists via queries.quoteUsdNow; never throws). - bb_launch_swaps.usd / bb_launch_fee_events.usd: each trade's and fee's value at its own hour, written in the event's own transaction together with new running sums bb_launches.volume_usd / fees_collected_usd / fees_burned_usd. No price for that hour means NULL (never a guess), left for the backfill. Fees are quote side only, as the USD fee totals always were. - scripts/usd-backfill.ts writes ONE reviewed SQL file and touches no database: - hourly prices from launch day: ETH-USD and HYPE-USD from Coinbase (HYPE gaps from Hyperliquid); GITLAWB from its GITLAWB/WETH pool via GeckoTerminal (price in WETH, forward-filled between trades) times ETH-USD, the live method; TWIG = GITLAWB; stables $1 - --mode dry-run prints old method vs trade-time per chain and quote, totals and fees, then ROLLS BACK - --mode apply prices rows with no USD value, then recomputes launch totals under the rebuild-launch-totals.sql locks - It never replaces an hour captured live, and stops at the last completed hour (a partial candle would block the live capture for the rest of the hour). - LAUNCH.md: the runbook. Points scoring is unchanged this season. Stocks, community pairs and unlisted quotes have no price history: their older trades stay without a USD value. Verified on a throwaway Postgres 16: - the real migrate.mjs applies on a fresh database and again unchanged - a fixture of ETH, Arc USDC, GITLAWB and unlisted-quote launches with trades and fees: the dry run reported the hand-computed values and left the database untouched; apply wrote exactly those values, kept the live-captured hour, left the unlisted trade and the token-side burn NULL, and a second apply changed nothing - the real captureLiveUsd wrote live rows through the real driver; a live 2-ETH trade priced at 2 x the captured spot and the launch total moved by exactly that The backfilled GITLAWB and ETH for the latest hour match the live site's within 1%. tsc and lint clean; npm test 1404 (1393 pass, 11 skipped, 0 fail).

Walkthrough

The PR adds hourly quote-price storage, historical USD backfill tooling, and live USD capture for launchpad swaps and fee events. Backfills can run in dry-run or apply mode. The indexer uses event-hour quote prices to store USD values and update launch totals.

Changes: Trade-Time USD Pricing

Layer / File(s)	Summary
Hourly price model and utilities `app/db/schema.sql`, `app/src/lib/launchpad/usd-history.ts`, `app/src/lib/launchpad/queries.ts`, `app/src/lib/launchpad/usd-history.test.ts`	Adds hourly quote-price storage and USD fields. Adds UTC-hour utilities, price parsers, gap filling, quote-series mapping, current quote-price lookup, and tests for these behaviors.
Historical backfill generation and application `app/scripts/usd-backfill.ts`, `app/src/lib/launchpad/usd-history.ts`, `app/db/concurrent-indexes.sql`, `app/src/lib/launchpad/usd-history.test.ts`, `app/LAUNCH.md`	The CLI fetches historical price data and generates dry-run or apply SQL. The SQL fills missing event USD values and recomputes launch totals. Adds a partial index, tests, and operational instructions.
Live capture and event accounting `app/src/lib/launchpad/usdLedger.ts`, `app/src/lib/launchpad/indexer.ts`, `app/src/lib/launchpad/usd-history.test.ts`	The indexer captures live quote prices and uses event-hour prices for swap and fee USD values. It updates launch USD totals and includes tests for pricing and capture order.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: Low · up to 30688

Under concurrent ingestion, some trades may be stored without a USD value until the next backfill, which understates the new USD totals. The site still uses the old figures, so the impact is bounded. Consider tracking in-flight captures before relying on these totals.

Wait for an in-flight capture before pricing trades.

If concurrent callers use the same chain, the second caller can skip capture before the first writes the hourly row. Its swap can then be stored with usd = NULL and remain unpriced until an eligible backfill.

Track the in-flight capture per chain. After waiting, recheck the requested hour and quotes, and retry if the capture failed.

…trade The read side of Twigpine#133. The all-time volume, the fee totals, each token's "Total volume" and the all-time Volume sort now read the stored trade-time values (each trade and fee at its own hour), instead of quote volume at today's price. Production was backfilled on 2026-11-10: $16,601,255 stored, against the $11.7M the old method showed. - trade-time-usd.ts (pure): tradeTimeUsd = the stored sum plus the raw amount with no stored value at today's price. That second part covers registry stocks, community pairs and unlisted tokens traded before the live capture started (no price history: 4,711 of 133k trades), so the totals stay complete. missingNow decides "partial": only that part can be missing a price. - queries.ts: - the list SELECT joins each launch's unpriced volume once (one grouped read on the usd-IS-NULL partial index) - shape() computes volume_usd from it and no longer passes the stored columns through - the all-time Volume sort ranks by the same figure - getLaunchTotals sums the stored values plus the unpriced parts; fees to recipients = collected - burned, both in trade-time USD - 1h/24h volume stays quote volume at today's price, where every trade is priced live anyway - LaunchMechanism: the tooltips say how the figures are valued (each at the hour it happened; stock and community-pair trades before Nov 10, 2026 at today's rate), not "valued at current rates". - Tests: trade-time-usd.test.ts. The totals fixture (price-source) moves to the new model, plus a case where a trade priced at $3,100 stays $3,100 at an ETH price of $2,500. The source checks for the partial rule, the select's aliases (the new `u` join) and the hero tooltip are updated; the db mock knows the new totals query. Not changed: CollectPanel's per-token fee figures and the live tape (recent trades, at today's price), points scoring (this season). Verified on a throwaway Postgres 16: the real migration, a fixture backfilled by the real apply SQL, then the real getLaunch / listLaunchesPage(volume, all) / getLaunchTotals at ETH = $2,500: - ETH $4,789.65, USDC $100, GITLAWB $18,893.73 - an unlisted quote null - an ETH trade from before the backfill range at today's price ($2,500) - sort CGIT > AETH > EOLD > BUSDC > DUNL - total $26,283.38, not partial - no stored column leaks into the API rows tsc and lint clean; npm test 1408 (1397 pass, 11 skipped, 0 fail). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

From a strict review of af4e6e5..133fabd (Twigpine#133, Twigpine#136): - Community pairs are never stored (usdLedger.capturable). A pair priced from an outside pool can be pushed for a minute, and a captured price stayed in the totals for good. A suspended or delisted pair must show no USD, which a stored value defeated. Their trades keep usd NULL and count at the pair's price now, which follows its listing status. The backfill (apply) clears pair values captured since Twigpine#133 and drops their ledger rows. - A launch row whose volume is partly unpriced while its quote has no price right now shows its quote amount (launchVolumeUsd: null) instead of a smaller dollar figure that looked complete. - The receipt path (applyLaunchTx, the user is waiting) no longer captures live prices: a capture could wait on Coinbase and Chainlink. Those trades take the hour's price the poller captured, or the heal pass prices them. - Heal pass (usdLedger.healUnpricedUsd), every 5 minutes per chain after a sync: - prices the last 3 days' trades and quote-side fees with no USD whose hour now has a price, and adds them to the launch totals in the same statement - skips pairs and re-tests usd IS NULL inside the UPDATE, so two machines change each row and each total once - Backfill apply is ONE transaction under the rebuild-launch-totals locks: pair cleanup, pricing and the totals recompute commit together. No reader sees rows priced but not yet summed, and a failure changes nothing. The dry run counts pairs as unpriced and stays write-free. - The lists probe one launch at a time (LATERAL u on the new partial index bb_launch_swaps_usd_missing_token_idx) instead of aggregating every unpriced trade per request. The totals' unpriced-fee read gets bb_launch_fee_events_usd_missing_idx. - scripts/rebuild-launch-totals.sql recomputes the USD totals too and reports USD drift before and after. - Wording: the tooltip and the partial note describe what has no recorded value. The backfill retries network errors and timeouts, not only 429/5xx. Deferred, not risky: the pairs pages and the token fee panel still use today's price; the volume sort mixes units during an ETH price outage (pre-existing); per-hour source labels; poolMaps / quoteUsdNow duplication. Verified on a throwaway Postgres 16 with the real migration (3 partial indexes built): - two concurrent heal passes priced the missed trade and fee once (AETH $2,000 → $6,200, not $10,400; fee $21); a rerun and a throttled run changed nothing; the pair stayed NULL - the dry run reported pairs as unpriced and changed nothing - apply (1 BEGIN / 1 COMMIT) cleared the old pair value and its ledger rows and left AETH at $6,200 - the repair script ran with 0 USD drift - the real reads: AETH $6,200, the pair row null (quote amount), sort ok, totals $6,200 and partial tsc and lint clean; npm test 1410 (1399 pass, 11 skipped, 0 fail).
