Restore support for initialFilters
applyFilters always overwrites whatever the parent passed in via initialFilters with undefined values because the local state boots with ''/'all'. On the first render the effect on Lines 79-82 fires, so we immediately send actions.setFilters({ …initialFilters, type: undefined, asset: undefined, search: undefined }). As a result the feed silently drops any pre-applied filters (e.g., a pool-specific asset or type restriction), breaking the contract of the filters prop. Please keep the original values unless the user actually chooses a different option—for example, clone initialFilters and only mutate keys when a concrete selection/search is present, or initialise the local state from initialFilters once.
🤖 Prompt for AI Agents
In frontend/src/components/modules/marketplace/ui/components/ActivityFeed.tsx
around lines 66 to 82, applyFilters currently spreads initialFilters but then
overwrites its keys with undefined because local state defaults ('', 'all') are
treated as “no selection”; this causes pre-applied parent filters to be lost on
first render. Fix by preserving initialFilters values unless the user has made a
concrete selection: either initialize local
searchQuery/selectedType/selectedAsset from initialFilters on mount, or when
building filters clone initialFilters and only set search/type/asset when their
local state is a real value (non-empty and not 'all'); then call
actions.setFilters with that merged object. Ensure the effect uses appropriate
dependencies so it doesn't clear initialFilters on first render.

Stop bubbling from the expand chevron.
Because the card itself toggles expansion on click, the chevron button fires handleExpand twice (its own handler plus the bubbled card click), so the row never opens. Prevent bubbling before toggling.

Keep “Copy Hash” from collapsing the row.
Copying the transaction hash currently bubbles to the card click handler and collapses the details you’re trying to read. Stop propagation so utility actions don’t fight the expand/collapse UX.

Transaction parsing never produces an ActivityType
The detection logic here assumes that StellarOperation.type contains keywords like “supply”, “borrow”, etc. In practice the Horizon API only ever surfaces canonical operation names (payment, path_payment_strict_send, manage_sell_offer, …). Because none of those include the Blend keywords, determineActivityType always returns null, which makes parseStellarTransaction bail out and yields zero activities from real Stellar transactions—a critical functional break. You’ll need to derive the activity type from reliable fields (e.g., memo data, operation details, attached metadata) instead of the generic Horizon type string.
🤖 Prompt for AI Agents
In frontend/src/helpers/transaction-monitoring.helper.ts around lines 99-120,
the current logic matches Blend activity keywords against Horizon's generic
operation.type (e.g., "payment") which never contains those keywords, so
determineActivityType always returns null; update the function to derive
ActivityType from reliable sources: inspect tx.memo (and decode if base64/hex)
for Blend event tags, and for each operation switch on op.type and examine
operation-specific fields (e.g., payment: asset/amount/to/from,
manage_sell_offer/manage_buy_offer: offer IDs and assets, manage_data or
invoke_host_function: custom keys/arguments, claimable_balance or account_merge
metadata) to detect Blend semantics, then map those concrete patterns to
ActivityType.SUPPLY/BORROW/REPAY/LIQUIDATION/WITHDRAWAL; add a clear mapping
table (or switch/case) and fallbacks (memo first, then op-specific checks) and
keep returning null only if no concrete match is found.

Fix stale loading guard in fetchActivities.
Because fetchActivities is memoized with [poolId, state.filters, pageSize], the state.loading value it reads at Line 80 is whatever was true when the callback was created. After the first request flips loading to true, the interval/polling loop and loadMore still see false and fire again, creating overlapping requests and inconsistent pagination. Please gate the fetch on a ref that tracks the live loading flag before issuing the call.

In frontend/src/hooks/usePoolActivity.ts around lines 48 to 109, the memoized
fetchActivities reads state.loading (stale inside the callback) causing
overlapping requests; replace that guard with a live ref. Add a loadingRef =
useRef(false) and check loadingRef.current at the top of fetchActivities; when
starting a request set loadingRef.current = true and setState loading:true, and
on both success and error set loadingRef.current = false and setState
loading:false. Ensure fetchActivities no longer depends on state.loading (keep
dependencies poolId, state.filters, pageSize) so it always uses the live
loadingRef to gate concurrent calls.

Debounce filters with the latest criteria.
The timeout inside setFilters reuses the old fetchActivities closure, so the request still runs with the previous state.filters. Nothing clears the timeout either, so rapid filter tweaks queue several stale fetches. Keep the current filters in a ref, clear the pending timeout before scheduling, and make fetchActivities consume the ref so it always sees the latest filters.

In frontend/src/hooks/usePoolActivity.ts around lines 125 to 137, the setFilters
debounce schedules fetchActivities via a timeout that closes over stale
state.filters and never clears previous timers; replace this by storing the
latest filters in a useRef (e.g., filtersRef.current = filters), store the
timeout id in another ref, call clearTimeout on that ref before scheduling a new
setTimeout, and have fetchActivities read filters from filtersRef (or accept
filters param sourced from the ref) so the debounced call always uses current
criteria; also clear the timeout in a useEffect cleanup/unmount to avoid stray
calls.
