useRescueERC20
Sweep stranded plain ERC-20 tokens (e.g. someone sent the wrong token).
@tokenops/sdk/fhe-disperse/react{ mutate, mutateAsync, isPending, error, data }Description
Admin: rescue accidentally-sent ERC-20 tokens from the singleton contract
itself (NOT the per-user subwallets — for those, use
useRecoverERC20FromWallets). Requires WITHDRAWER_ROLE.
Signature
function useRescueERC20(options?: DisperseHookOptions): UseMutationResult<Hex, Error, UseRescueERC20Args>;Parameters
Shape of the object you pass to .mutate(args).
| Property | Type | Description |
|---|---|---|
| tokenrequired | Address | ERC-20 token to rescue. |
| torequired | Address | Recipient of the rescued tokens. |
| account | Account | Address | Override signer account. Falls back to walletClient.account. |
Example
const rescue = useRescueERC20();
rescue.mutate({ token, to: treasury });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 viem-passthrough errors. Product classes carry the offending value as fields — render them inline instead of a generic "transaction failed." See Disperse › 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).
import { useQueryClient } from "@tanstack/react-query";
const queryClient = useQueryClient();
const rescueERC20 = useRescueERC20(/* options */);
rescueERC20.mutate(args, {
onSuccess() {
// Coarse invalidation: refresh every cached read on this product surface.
queryClient.invalidateQueries({
queryKey: ["tokenops-sdk", "fhe-disperse"],
});
},
