v2.0.0-rc.1 release candidate

The API is frozen and later candidates carry fixes only, except the receipt-free and Safe create surface of /fhe-airdrop, which is @beta. Published on the next dist-tag; latest stays on 1.6.0 until 2.0.0.

Description

Set the account seeded with FEE_COLLECTOR_ROLE on instances the factory creates after this call. Existing instances keep their own collectors, and withdrawGasFee sends to the recipient its caller names.

Requires FEE_MANAGER_ROLE. The headless factory method takes positional args, so this hook adapts its object-shaped variables to setFeeCollector(feeCollector, account?, gas?).

Invalidates: this factory's useFactoryFees entry (fn "fees"), which bundles feeCollector with defaultGasFee. Nothing else moves - deployed instances hold no copy of the collector.

Signature

@tokenops/sdk/fhe-airdrop/advanced/react

function useSetFeeCollector(options?: AirdropClientOptions): UseMutationResult<Hex, Error, SetFeeCollectorArgs>;

Parameters

Shape of the object you pass to .mutate(args) is the SDK type SetFeeCollectorArgs. Inspect the type for the full shape (discriminated unions collapse to a tagged variant at call time).

Want to run a similar shape interactively? The Playground ships 12 ready presets across vesting / airdrop / disperse / faucet — deploy a manager, create a vesting, claim, and run the product equivalents. The deep-link above auto-selects the closest preset to useSetFeeCollector; pick another from the dropdown if you'd rather start there.

Example

@tokenops/sdk/fhe-airdrop/advanced/react · @example

tsx

const setCollector = useSetFeeCollector();
await setCollector.mutateAsync({ feeCollector: treasuryAddress });

Pulled directly from the hook's TSDoc block — the same snippet your IDE shows on hover.

Errors

This mutation can reject with SDK-level, product-level, or generic-fallback errors. Product classes carry the offending value as fields — render them inline instead of a generic "transaction failed." See Airdrop v2 › Errors for the per-class recovery table.

Invalidation recipe

After this mutation succeeds, invalidate the queries it affects so consumer UI re-fetches fresh state. The SDK never auto-invalidates — that's a consumer decision (different apps cache different shapes).

patterns/invalidation.ts

import { useQueryClient } from "@tanstack/react-query";

const queryClient = useQueryClient();
const setFeeCollector = useSetFeeCollector(/* options */);

setFeeCollector.mutate(args, {
  onSuccess() {
    // Coarse invalidation: refresh every cached read on this product surface.
    queryClient.invalidateQueries({
      queryKey: ["tokenops-sdk", "fhe-airdrop"],
    });
  },
});
