 ## Transaction Ledger Table — Data Flow
 
 How the table gets its rows and values:
 
-1. **Fetch:** `fetchAllWalletData()` → `fetchWalletAaveData(address)` hits `/api/v1/portfolio/{address}/base/aave`, returns array of snapshot events.
+1. **Fetch:** `fetchWalletAaveData(address, chain)` hits `/api/v1/portfolio/{address}/{chain}/aave` (chain-parameterized, defaults `base`), returns array of snapshot events.
 2. **Deduplicate:** `snapshotsToDaily(events)` collapses events to one per day (keeps latest `block_timestamp` per day). **Result is sorted newest-first.**
 3. **Store:** Deduplicated snapshots land in `addressSnapshots[address]`.
 4. **Prices:** `fetchPrices(symbols, oldestDateMs)` fetches `/api/v1/prices/{symbol}/history?range=N` where N = days between now and oldest snapshot. **Critical:** you must scan all snapshots for the *lowest* `block_timestamp` to compute the correct range. `snapshots[0]` is the *newest* — never assume the array is oldest-first. The `aavePriceMap` is keyed `[priceSymbol][dateStr] = closePrice`.
