+     * @return totalZeroYieldPayable The MON amount earmarked for zero-yield obligations (e.g., commission accruals).
+     * https://github.com/FastLane-Labs/fastlane-contracts/blob/485e9305b251089b94f62ef22b7ab9a74e0d32c3/src/shmonad/Storage.sol#L157
+*/
+const globalLiabilitiesAbi = "function globalLiabilities() view returns (uint128 rewardsPayable, uint128 redemptionsPayable, uint128 totalZeroYieldPayable)";


I would wrap all abi variables inside a single variable like ABIS = { getAtomicCapitalAbi, ... }, it makes codes easier to read

noateden · 2025-12-02T17:14:14Z

fees/shmonad/index.ts

+const getAtomicCapitalAbi = "function getAtomicCapital() view returns (uint256 allocated, uint256 distributed)";
+const getCurrentAssetsAbi = "function getCurrentAssets() view returns (uint256)";
+const getWorkingCapitalAbi = "function getWorkingCapital() view returns (uint256 staked, uint256 reserved)";
+const totalSupplyAbi = "function totalSupply() view returns (uint256)";


let you know we support simple form of abi for function like totalSupply
Instead of function totalSupply() view returns (uint256)
you can use uint256:totalSupply

fees/shmonad/index.ts

+    atomicCapital.allocated +
+    currentAssets;
+
+  const totalLiabilities =


Do we really need to calculate this? Because I can see we can get Liabilities from atomicCapital, something like this:
https://github.com/DefiLlama/DefiLlama-Adapters/blob/main/projects/shmonad/index.js#L27

noateden · 2025-12-02T17:18:54Z

fees/shmonad/index.ts

+  return totalAssets - totalLiabilities;
+}
+
+const getFetch = () => {


please don't do this, except when you need to pass parameters to getFetch function. I would use simple function

const fetch = async (options: FetchOptions) => { // code logics }

fees/shmonad/index.ts

+    const dailyProtocolRevenue = options.createBalances();
+    const dailySupplySideRevenue = options.createBalances();
+
+    try {


you don't need try catch here, you should throw Error when failed to read contract

noateden · 2025-12-02T17:20:27Z

+        options.fromApi.call({ target: SHMONAD_CONTRACT, abi: getWorkingCapitalAbi }),

+        options.fromApi.call({ target: SHMONAD_CONTRACT, abi: getCurrentAssetsAbi }),
+        options.fromApi.call({ target: SHMONAD_CONTRACT, abi: globalLiabilitiesAbi }),


check this codes, you can reduce the globalLiabilitiesAbi contract call

+
+      // CONVERT TO BIGINT
+      // Helper function to safely convert contract return objects to BigInt structure.
+      const toBigInt = (obj: any) => ({


you don't need to do this, because sdk return data in BigInt already

noateden

can you check the contract again? I believe it was an ERC 4626 vault, so you can get the exchange rate before/after by using 2 api calls only

+      if (totalRewards > 0n) {

Does shmond distribute rewards to stakers pre or post protocol revenue cut?

Does shmond distribute rewards to stakers pre or post protocol revenue cut?

shmond distribute rewards to stakers post protocol revenue cut

Thanks for the detailed review @noateden — noted on all points.
I’ll update the PR accordingly

The contract is indeed an ERC 4626 vault. Thanks for the clarification!
