Why

Percent returns cannot isolate investment performance from deposits and withdrawals while the performance cache only stores equity snapshots.

How

Pull Hyperliquid non-funding ledger deposits and withdrawals on refresh, and Derive settled deposit and withdrawal history on browser sync, into typed Deposit and Withdraw cache events.

Closes #516

Summary by CodeRabbit

  • New Features
    • Account performance history now includes eligible deposits and withdrawals, alongside account value history, for supported Derive and Hyperliquid accounts.
    • Cash-flow entries show their timestamp and USD amount, helping provide a fuller view of changes in account value.
    • Hyperliquid account value history now combines data across available time windows and orders points chronologically.

Walkthrough

Hyperliquid and Derive performance syncs now collect deposit and withdrawal events and store them with equity points. Event types are explicit, and Hyperliquid portfolio parsing combines samples across available history windows.

Changes

Cash-flow event collection

Layer / File(s) Summary
Hyperliquid ledger events
src/account_performance.rs
Portfolio parsing combines samples from available windows and sorts them by timestamp. Refresh parses non-funding ledger updates into deposit and withdrawal events and stores them with equity points.
Derive cash-flow history
frontend/src/services/account-performance.ts, frontend/src/services/derive/performance.ts, frontend/src/services/derive/performance.test.ts
The event type is used in the performance cache contract. Derive sync requests deposit and withdrawal histories, converts eligible rows into events, and stores the events with equity points. Tests cover conversion of settled USDC deposits.

Priority: ➖ Normal

Change: Feature · Severity of issue fixed: Medium

Merge Risk: 🟡 Moderate · up to d297d

This change can make some cached wallet performance fail to load. It can also store incomplete or inaccurate deposit and withdrawal history for active accounts. Resolve these issues before relying on these events for return calculations.

Security Architecture Review

Security architecture risk: 🟠 High · up to d297d

Deposit and withdrawal history is more sensitive than the equity snapshots previously cached. The new data may be readable or replaceable through existing wallet-based endpoints, and incomplete history can replace a valid cache entry. Deployment-level access controls have not been established.

Retained concerns

  • High · security · inferred: Session-authenticated Derive deposit and withdrawal history is copied into a wallet-keyed cache served by a GET route without a wallet-ownership control visible in the handler or router. A caller able to reach that route and name a cached wallet could read its transaction history; an external access restriction could limit this exposure but was not established.
  • Medium · security · inferred: The existing wallet-keyed PUT route now accepts meaningful typed deposit and withdrawal records without a wallet-ownership or event-provenance check visible at the route or cache write. A caller able to reach it could replace another wallet's cached cash-flow history. The writable route and equity-replacement capability predate this PR; the newly forgeable typed history is the change in exposure.
  • Medium · security · inferred: A successful but empty or incomplete history can replace previously cached cash-flow events. Derive treats a missing or non-array events field as empty; Hyperliquid parsing permits empty results and skips some entries. The unconditional row replacement also permits an older concurrent refresh to finish last. These paths can make missing or stale history appear current.
Security review details

Security Blast Radius

  • inferred — The potential read and replacement scope is each wallet with a cached venue row, rather than only the browser session that fetched its Derive history. Effective network reachability and perimeter controls were not established.

Security Findings and Attack Paths

  • inferred — If the performance routes are reachable without an outer access control, knowing a wallet address is sufficient to request its newly cached Derive transaction history or submit replacement typed events. The absence of an outer control has not been proved.

Trust Boundaries and Controls

  • observed — Derive private requests use the same session wallet and subaccount as the existing value-history request. Hyperliquid refresh normalizes the requested wallet and uses it for both upstream requests and the cache key; malformed upstream responses can abort before replacement.

Resilience and Maintainability Implications

  • inferred — A failed upstream request preserves the prior row, but a successful empty history or later-finishing stale refresh can replace it. No source-completeness marker or monotonic write guard is visible in these flows.

Hardening Proposals

  • proposed — Establish wallet-bound read and write authorization or explicitly keep private cash-flow history out of the shared wallet cache; validate history completeness before replacement and guard against stale writes. Define how any legacy Placeholder rows are handled on rollout.

Accept only explicitly settled cash flows.

If a Derive history entry omits tx_status, isSettledCashFlow returns true. A non-settled row with no status can therefore enter the cached cash-flow events. Treat only "settled" as settled.

Suggested fix
 const isSettledCashFlow = (status: string | undefined): boolean =>
-  status === undefined || status === "settled"
+  status === "settled"

Account for settled non-USD cash flows.

When a user deposits or withdraws ETH, this branch drops the settled event while the equity history can still change. A later return calculation cannot distinguish that external cash flow from investment performance. Convert supported assets to their historical USD value before caching, or define how the cache will represent their asset amounts. The new test confirms that settled ETH is currently excluded.

Preserve the original amount string during conversion.

parseDeriveNumeric uses Number.parseFloat on a Derive amount string. The subsequent toString() stores the rounded floating-point value, not the original decimal amount. Parse and validate with an arbitrary-precision decimal type, then serialize that value to amount_usd. Derive’s official SDK also advises using decimals rather than floats for amounts. (github.com) Based on learnings: “never route large numeric strings ... through Number()” because floating-point conversion loses precision.

Preserve Placeholder for cache compatibility.

The PUT /performance/{wallet}/{venue} endpoint accepts client-supplied events. The previous enum accepted {"kind":"placeholder","note":...}, so such a row can exist. Removing the variant makes GET /performance/{wallet} fail when it deserializes that row.

The absolute-value normalization discards the withdraw fee and hides the sign.

For Hyperliquid withdraw deltas, usdc is the amount the user receives. The fee is also deducted from account equity. If the event records only usdc, the fee appears as an investment loss in cash-flow-aware returns. Add fee to the withdraw amount. Alternatively, document that the fee is intentionally excluded.

Proposed fix
-        let amount_usd = decimal_from_json_value(amount_value, timestamp_ms)?.abs();
+        let base_amount = decimal_from_json_value(amount_value, timestamp_ms)?.abs();
+        let fee = match (delta_type, delta.get("fee")) {

🌐 Web query:

Hyperliquid userNonFundingLedgerUpdates response limit pagination startTime

💡 Result:

`userNonFundingLedgerUpdates` has a **500-item response cap** for time-ranged queries. To fetch more, split the time range into pages: use the last item’s `time` as the next request’s inclusive `startTime`, then deduplicate the overlapping timestamp. ([hyperliquid.gitbook.io](https://hyperliquid.gitbook.io/Hyperliquid-docs/for-developers/api/info-endpoint?utm_source=openai))

```json
{
  "type": "userNonFundingLedgerUpdates",
  "user": "0x...",
  "startTime": 1700000000000,
  "endTime": 1700100000000
}
```

`startTime` is in **milliseconds** and inclusive; `endTime` is also inclusive and defaults to the current time if omitted. ([hyperliquid.gitbook.io](https://hyperliquid.gitbook.io/hyperliquid-docs/for-developers/api/info-endpoint/perpetuals?utm_source=openai))

If a page ends with many events at the same timestamp, advancing by `last.time + 1` could skip some. Instead, request again from `last.time` and deduplicate by event identity (for example, hash plus event data).

Paginate the ledger history before caching it.

userNonFundingLedgerUpdates caps responses at 500 rows. The single request with startTime: 0 can omit ledger events for wallets with longer histories before events is passed to upsert_venue_series. Fetch subsequent pages from the last event timestamp, deduplicate the inclusive overlap, and stop when a page contains fewer than 500 rows.

Paginate the `userNonFundingLedgerUpdates` request before passing events to
`upsert_venue_series`; the single request can truncate histories at 500 rows.
Continue fetching from the last event timestamp, deduplicate events repeated at
the inclusive boundary, and stop once a response contains fewer than 500 rows.
