Description

Read an ECDSA instance's CLAIM_TYPEHASH, domain separator and ERC-5267 domain in one round trip - the three deployment-verification reads nobody wants one at a time (same call as useAirdropWindow).

This is the round-trip confirmation, not the common path. For building a signature, use the module-level CLAIM_TYPEHASH / EIP712_DOMAIN_NAME / EIP712_DOMAIN_VERSION constants and skip the RPC. Use this hook to confirm a deployed instance really was initialized with the domain you expect, on the chain you think it is on, before a signing service starts issuing signatures against it.

All three are bytecode/deploy constants, so staleTime: Infinity.

Signature

@tokenops/sdk/fhe-airdrop/react

function useEcdsaDomain(args: UseEcdsaDomainArgs): UseQueryResult<EcdsaDomain, Error>;

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 useEcdsaDomain; pick another from the dropdown if you'd rather start there.

Example

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

tsx

const { data } = useEcdsaDomain({ address: airdropAddress });
const built = data?.claimTypehash === CLAIM_TYPEHASH;

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