Lifecycle

Recovery · pause / withdraw

Description

Fee-collector: withdraw accumulated encrypted token fees. Pass either a plaintext amount (SDK encrypts) or a pre-encrypted encryptedInput — never both. The contract caps the withdrawal at the available reserve via FHE.min.

Returns { hash, transferredHandle } parsed from the TokenFeeWithdrawn event. The handle is decryptable by the caller via Zama's userDecrypt and reveals the actual transferred amount, which may be less than the requested amount when the reserve was lower.

Encryptor resolution (plaintext path only). Pass encryptor per-call, or supply it at hook construction via DisperseHookOptions.encryptor. If neither is present, the SDK throws Missing encryptor — pass encryptor… verbatim.

Requires FEE_COLLECTOR_ROLE.

Signature

@tokenops/sdk/fhe-disperse/react

function useWithdrawTokenFee(options?: DisperseHookOptions): UseMutationResult<WithdrawTokenFeeResult, Error, UseWithdrawTokenFeeArgs>;

Parameters

Shape of the object you pass to .mutate(args) is the SDK type UseWithdrawTokenFeeArgs. 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 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 useWithdrawTokenFee; pick another from the dropdown if you'd rather start there.

Examples

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

tsx

function Component() {
  const zamaSDK = useZamaSDK();
  const withdraw = useWithdrawTokenFee({ encryptor: () => zamaSDK.relayer });
  withdraw.mutate({ token, to: collector, amount: 1_000_000n });
}

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

tsx

// Pre-encrypted path — no encryptor needed at call time.
withdraw.mutate({ token, to: collector, encryptedInput });

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

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 withdrawTokenFee = useWithdrawTokenFee(/* options */);

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