After success, invalidate useGetFees for every user and any UI panels showing the global config.

Signature

@tokenops/sdk/fhe-disperse/react

function useSetFeeConfig(options?: DisperseHookOptions): UseMutationResult<Hex, Error, UseSetFeeConfigArgs>;

Parameters

Shape of the object you pass to .mutate(args).

Property	Type	Description
configrequired	FeeConfig
account	Account \| Address	Override signer account. Falls back to `walletClient.account`.

The Playground ships 8 ready presets across vesting / airdrop / disperse — deploy a manager, create a vesting, claim, and the airdrop / disperse equivalents. The deep-link above auto-selects the closest preset to useSetFeeConfig; pick another from the dropdown if you'd rather start there.

Example

@tokenops/sdk/fhe-disperse/react · @example

tsx

const setFeeConfig = useSetFeeConfig();
setFeeConfig.mutate({
  config: { gasFeeEnabled: true, tokenFeeEnabled: false, defaultGasFee: 10_000_000_000_000_000n, defaultTokenFee: 0 },
});

Errors

This mutation can reject with SDK-level, product-level, or viem-passthrough errors. Product classes carry the offending value as fields — render them inline instead of a generic "transaction failed." See Disperse › 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 setFeeConfig = useSetFeeConfig(/* options */);

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