# Fee Grants

> Using the fee grant module to let one account pay fees for another

Cosmos SDK's fee grant module allows one account (the **granter**) to pay
transaction fees on behalf of another account (the **grantee**). This is useful
for onboarding users who don't yet hold tokens.

## Sending a Transaction with a Fee Grant

Set the `granter` field on the `StdFee` object:

```typescript theme={"system"}
import { coins } from "@cosmjs/proto-signing";

const fee = {
  amount: coins(5000, "uatom"),
  gas: "200000",
  granter: "cosmos1granter...",
};

const result = await client.signAndBroadcast(granteeAddress, messages, fee);
```

The granter must have previously granted a fee allowance to the grantee on-chain
(using `MsgGrantAllowance`).

## Querying Fee Allowances

Use the feegrant query extension to check existing grants:

```typescript theme={"system"}
import {
  QueryClient,
  setupFeegrantExtension,
} from "@cosmjs/stargate";
import { connectComet } from "@cosmjs/tendermint-rpc";

const cometClient = await connectComet("https://rpc.my-chain.network");
const queryClient = QueryClient.withExtensions(
  cometClient,
  setupFeegrantExtension,
);

const allowance = await queryClient.feegrant.allowance(
  "cosmos1granter...",
  "cosmos1grantee...",
);

const allAllowances = await queryClient.feegrant.allowances(
  "cosmos1grantee...",
);
```
