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.

Lifecycle

Description

Move an airdrop instance's claim-window end time forward. Requires WINDOW_ADMIN_ROLE, and only succeeds on an instance created with canExtendClaimWindow: true. newEndTime must be later than both the current end and the chain's current block timestamp; an end not more than 60 seconds after the latest block's timestamp is refused before sending (InvalidArgumentError on newEndTime), since the block that mines it can overtake a closer end.

Invalidates: only this instance's useAirdropWindow entry — endTime is one of the five fields that hook bundles. Not invalidated: the window blockers of usePreflightClaim and a cached false from useIsSignatureValid, both of which a later endTime can move; refetch them if the same session renders a claim form.

Signature

@tokenops/sdk/fhe-airdrop/react

function useExtendClaimWindow(options: AirdropInstanceClientOptions): UseMutationResult<Hex, Error, ExtendClaimWindowArgs>;

Parameters

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

Example

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

tsx

const extend = useExtendClaimWindow({ address: airdropAddress });
await extend.mutateAsync({ newEndTime: Math.floor(Date.now() / 1000) + 86_400 });

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 extendClaimWindow = useExtendClaimWindow(/* options */);

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