# Session keys with outside execution

[Outside Execution](/aa-use-cases/outside-execution.md) (Meta-transactions in the Ethereum world)  allows external contracts to execute transactions from outside an account contract, thereby opening up new use-cases such as sponsored transactions, deploying an account on behalf of a user, transaction scheduling (limit orders) etc.

The setup is exactly the same as the "basic" session keys.  We simply have a few more steps to do:

#### 1. Prepare the contract call

```tsx
// example for creating the calldata
const erc20Contract = new Contract(
  Erc20Abi as Abi,
  ETHTokenAddress,
  sessionAccount
)

const calldata = erc20Contract.populate("transfer", {
  recipient: address,
  amount: parseInputAmountToUint256(amount)
})

```

#### 2. Prepare Execution from outside

Here you have two possibilities. Depending on your setup, you can chose between a "higher level" function with `createOutsideExecutionCall`  which returns a signed call and a "lower level" with `createOutsideExecutionTypedData`  which returns the session acout signature and the typed data. 

#### a. Get the raw Execute from outside call

```typescript
import { createOutsideExecutionCall } from "@argent/x-sessions"

const efoExecutionCall = await createOutsideExecutionCall({
        session, // same object as before
        sessionKey, // same object as before
        calls: [calldata],
        argentSessionServiceUrl: ARGENT_SESSION_SERVICE_BASE_URL,
        network:
          CHAIN_ID === constants.NetworkName.SN_SEPOLIA ? "sepolia" : "mainnet",
      })
```

#### 2.b. Get the signed Execute from outside call

```typescript
import { createOutsideExecutionTypedData } from "@argent/x-sessions"

const { signature, outsideExecutionTypedData } =
  await createOutsideExecutionTypedData({
    session,
    sessionKey,
    calls: [calldata],
    argentSessionServiceUrl: ARGENT_SESSION_SERVICE_BASE_URL
    network // values "mainnet" | "sepolia", default to "mainnet"
  })
```
