# Usage limit

Limit how many times a session function can be called.

Examples on this page use `@rhinestone/sdk`, where `rhinestone` is the `RhinestoneSDK` instance from [Create a session with a custom setup](/wallets/session-keys/custom-setup/create-a-session).

```ts {16} theme={null}
import { erc20Abi } from "viem";
import { base } from "viem/chains";

const session = await rhinestone.createSession({
  chain: base,
  owners: {
    type: "ecdsa",
    accounts: [sessionOwnerAccount],
  },
  permissions: [
    {
      abi: erc20Abi,
      address: usdcAddress,
      functions: {
        transfer: {
          maxUses: 10n,
        },
      },
    },
  ],
});
```

This caps the function at 10 calls.
