+      params: [event.reserve],
+      skipCache: true,
+      permitFailure: false,
+      block: event.blockNumber - 1,


this line is why the block parameter you set here are ignored: https://github.com/DefiLlama/defillama-sdk/blob/master/src/ChainApi.ts#L48

so, instead of options.api, you need to use the vannila sdk.api2.call like here:
https://github.com/DefiLlama/DefiLlama-Adapters/blob/main/projects/contango/index.js#L21

but, approx how many of these events are emitted per day? if it is a lot, one rpc call per event is not exactly scalable

g1nt0ki · 2025-03-26T23:34:46Z

helpers/aave/index.ts

+  // get reserves configs, mainly reserveFactor values
+  const reserveConfigs = await options.api.multiCall({
+    abi: AaveAbis.getReserveConfiguration,
+    calls: reservesList.map(


no need for the map here, you can move the target to the top level and do calls: reservesList,

g1nt0ki · 2025-03-26T23:35:43Z

helpers/aave/index.ts

+        const totalDailySupplySideRevenue = options.createBalances()
+
+        for (const pool of pools) {
+          const { dailyFees, dailyRevenue } = await getPoolFees(pool, options)


why not pass dailyFees & dailyRevenue as third arg, this way, you dont have add everything up later

g1nt0ki · 2025-03-26T23:37:28Z

helpers/aave/index.ts

+          totalDailyHoldersRevenue.addBalances(dailyRevenue)
+
+          Object.entries(dailyRevenue.getBalances()).forEach(([token, balance]) => {
+            totalDailySupplySideRevenue.addTokenVannila(token, Number(balance) * -1)


you can simplify this by cloning the dailyFees object (.clone() ) and then subtracting daily revenue object (https://github.com/DefiLlama/defillama-sdk/blob/master/src/Balances.ts#L153)
