Description

Deploy AND fund a new airdrop clone in a single transaction. The SDK encrypts the plaintext amount into an externalEuint64 and submits it with an input proof — callers never handle ciphertext.

Encryptor resolution. The hook-level encryptor (from FactoryHookOptions) is forwarded lazily to the SDK client. You can also pass encryptor per-mutation via args.encryptor to override it. If neither is present, the SDK throws Missing encryptor — pass encryptor… verbatim.

Prerequisites: caller must have set the factory as an operator on the token: token.setOperator(factoryAddress, deadline).

After success, invalidate factory queries that depend on per-creator state:

function Component() {
  const queryClient = useQueryClient();
  const zamaSDK = useZamaSDK();
  const create = useCreateAndFundConfidentialAirdrop({ encryptor: () => zamaSDK.relayer });
  create.mutate(args, {
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ["tokenops-sdk", "fhe-airdrop"] });
    },
  });
}

Signature

@tokenops/sdk/fhe-airdrop/react

function useCreateAndFundConfidentialAirdrop(options?: FactoryHookOptions): UseMutationResult<CreateAirdropResult, Error, CreateAndFundAirdropArgs>;

Parameters

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

Example

components/useCreateAndFundConfidentialAirdropExample.tsx

tsx

"use client";
import { useCreateAndFundConfidentialAirdrop } from "@tokenops/sdk/fhe-airdrop/react";

export function Example() {
  const { mutate, isPending } = useCreateAndFundConfidentialAirdrop();

  return (
    <button disabled={isPending} onClick={() => mutate(/* args */)}>
      {isPending ? "Sending…" : "CreateAndFundConfidentialAirdrop"}
    </button>
  );
}

Auto-generated from the hook's shape (the SDK doesn't carry a TSDoc @example here yet).

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 Airdrop › 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 createAndFundConfidentialAirdrop = useCreateAndFundConfidentialAirdrop(/* options */);

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