How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits within each organization. For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window. Please refer docs for additional details.

WalkthroughThe portfolio now preserves block or local timestamp provenance, backfills cached timestamps, reports incomplete or truncated history, and displays persisted buy and sell transactions in a paginated ChangesPortfolio trade history
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The trade history feature can hide completed positions, remain stuck loading when local storage initialization fails, misreport truncated histories as complete, overload RPC providers on large histories, and display trades in the wrong order; the current implementation should not merge until these correctness and availability issues are addressed.

Inline comments:
In `@src/app/portfolio/page.tsx`:
- Around line 2629-2637: Render TradeHistoryCard independently of the
poolsData.length condition so persisted trade history remains visible after all
positions are sold. Keep its existing props and reloadKey behavior, while
preserving the empty state when no cached or scanned trades exist.
- Around line 496-500: The watermark written by the truncated-save path in the
scan flow must remain authoritative for subsequent resumes; do not let cached
retained trades override it and skip the omitted range. Update the
resume-boundary logic associated with writeScanWatermark and persistTruncated so
scans continue from the truncation watermark until the omitted trades are
retained or intentionally rescanned, while preserving normal non-truncated
behavior. Add a regression test covering more than 30 trades spanning more than
REORG_BUFFER blocks and verifying the card does not incorrectly report all
trades.
- Around line 564-579: Update the resolveBlockTimestamps flow around the pending
block list and client.getBlock calls to limit concurrent RPC requests, using
bounded chunks or an existing concurrency limiter. Preserve timestamp mapping,
per-request failure handling, and the existing completion logging while ensuring
large pending lists cannot create an unbounded Promise.all burst.
In `@src/components/Portfolio/TradeHistoryCard.tsx`:
- Around line 94-109: The TradeHistoryCard loading effect must handle IndexedDB
initialization failure instead of leaving the skeleton visible indefinitely.
Read the storage error state alongside isInitialized, set a terminal
cache-unavailable state when initialization fails, and render the corresponding
notice; preserve the existing transaction-loading path for successful
initialization.
- Around line 142-158: Externalize all user-visible text in TradeHistoryCard,
including the card title and description, notices, table headings, tooltips, and
pagination labels, using the project’s existing i18n resources and translation
mechanism. Update the affected JSX and related sections around the visible
header plus the referenced ranges, passing trade counts and other dynamic
formatting values as translation parameters rather than interpolating them in
code.
- Around line 121-126: Update the transaction event-mapping flow used by
TradeHistoryCard to persist both transactionIndex and logIndex for each trade.
In the sorted computation, retain blockNumber as the primary key, then order
equal-block trades by transactionIndex and logIndex instead of id.

The Trade History card lists every
BuyandSellmade by the wallet, with the newest trades shown first.Additional Notes:
Incomplete vs truncated history
These are different failures and previously only the first existed.
historyIncompletestill means a log read failed. NewhistoryTruncatedmeans the read succeeded and the store deliberately kept less: only the 30 most recent trades per (pool, coin side) are persisted.Without the second flag, a user whose scan succeeded and who has more than 30 trades on one leg gets a short list with nothing distinguishing it from a complete one. Each flag now drives its own notice, and the card claims "All N trades" only when neither is set.
No IndexedDB version bump.
timestampSourceis an optional field, which needs none, and a bump is actively harmful here: the localStorage scan watermark survives it, so wiped rows would never be re-scanned and the loss would be permanent.Known limitation, disclosed and not fixed here
On a warm load the FIFO runs over the persisted, capped set, because
resumeFrom = MAX(watermark, cachedThrough)always pickscachedThrough. That defeats theoldestKept - 1hold-back. So for a position past the cap, cost basis is built from the newest 30 trades whilecurrentValueuses the full balance: basis understated, P&L overstated.This is latent, not live. The store is never pruned, so rows accumulate; the loss would only be history beyond the newest 30 at the moment of the first successful scan. Measured against the live Sepolia pools, the busiest position is at 18 of 30 (11 buys, 7 sells), so nothing is over the cap today. Fixing it means changing the cap, which is its own change and does not belong in a PR that introduces a card.
