Description

AccessControl: grant role to accountTarget on this airdrop clone. Caller must be a member of the role's admin role. For most roles that admin role is DEFAULT_ADMIN_ROLE, but FEE_COLLECTOR_ROLE is self-administered — its admin role is FEE_COLLECTOR_ROLE itself, so a DEFAULT_ADMIN_ROLE-only holder cannot grant it; only an existing FEE_COLLECTOR_ROLE member can.

After success, invalidate useAirdropHasRole({ role, account: accountTarget }).

Signature

@tokenops/sdk/fhe-airdrop/react
ts
function useAirdropGrantRole(options: AirdropInstanceClientOptions): UseMutationResult<Hex, Error, AirdropGrantRoleArgs>;

Parameters

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

Example

@tokenops/sdk/fhe-airdrop/react · @example
tsx
const grant = useAirdropGrantRole({ address: airdropAddress });
await grant.mutateAsync({ role: roles.PAUSER_ROLE, holder: opsAddress });

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

const queryClient = useQueryClient();
const airdropGrantRole = useAirdropGrantRole(/* options */);

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