# ApprovalModes

> The ApprovalModes enum for getAllowance and approve.

Use with `getAllowance` and `approve` (parameter name is `mode`, not `permitType`):

```typescript theme={null}
import { ApprovalModes } from "@dzapio/sdk";

ApprovalModes.Default;                      // Standard ERC20 approval
ApprovalModes.PermitSingle;
ApprovalModes.PermitWitnessTransferFrom;
ApprovalModes.PermitBatchWitnessTransferFrom;
ApprovalModes.AutoPermit;                   // Recommended: auto-select best
```
