Description

Read spender's ERC-7984 operator status for holder on token.

Typical use: gate the "create" call-to-action behind the operator prerequisite so builders never hit OperatorNotApprovedError — the SDK's mapping of the on-chain ERC7984UnauthorizedSpender revert, whose message is the canonical OPERATOR_NOT_APPROVED_REMEDIATION copy:

Signature

@tokenops/sdk/fhe-vesting/react

function useIsOperator(options?: UseIsOperatorOptions): UseQueryResult<boolean, Error>;

Parameters

Shape of the options object passed to the hook itself.

Property	Type	Description
token	Address \| undefined	ERC-7984 token contract address. Query stays disabled while `undefined`.
spender	Address \| undefined	Address whose operator status is being checked — typically a manager clone, an airdrop factory/clone, or the disperse singleton. Query stays disabled while `undefined`.
holder	Address \| undefined	Account that owns the tokens. Defaults to the connected wallet's account. Query stays disabled while neither is available.
chainId	number \| undefined	Override the chain id used for client resolution.
enabled	boolean \| undefined	Set `false` to pause the query without unmounting. Defaults to `true`.
telemetry	SdkTelemetry \| undefined	Optional telemetry adapter — forwarded to the headless helper.

Want to run a similar shape interactively? The Playground ships 8 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 useIsOperator; pick another from the dropdown if you'd rather start there.

Example

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

tsx

const { data: authorized } = useIsOperator({ token, spender: manager });
return authorized
  ? <CreateVestingButton />
  : <ApproveOperatorButton />; // wire to useEnsureOperator
```

After a successful {@link useEnsureOperator} / `setOperator` mutation,
invalidate this query (its key starts with
`["tokenops-sdk", "fhe", "isOperator", ...]`) or refetch it.

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