# Delegation Manager

The Delegation Manager is a core component of the [Delegation Framework](/smart-accounts-kit/concepts/delegation/overview/#delegation-framework). It validates delegations and triggers executions on behalf of the delegator, ensuring tasks are executed accurately, and securely.

See the [delegation flow](/smart-accounts-kit/concepts/delegation/overview/#delegation-flow) for a full overview of how delegations are created, validated, and redeemed.

## Execution modes[​](#execution-modes "Direct link to Execution modes")

The Delegation Manager processes delegations based on a specified execution mode. When redeeming a delegation using [redeemDelegations](/smart-accounts-kit/reference/delegation/#redeemdelegations), you must pass an execution mode for each delegation chain you pass to the method. The Smart Accounts Kit supports the following execution modes, based on [ERC-7579](https://erc7579.com/):

| Execution mode | Number of delegation chains passed to redeemDelegations | Processing method | Does user operation continue execution if redemption reverts? |
| -------------- | ------------------------------------------------------- | ----------------- | ------------------------------------------------------------- |
| SingleDefault  | One                                                     | Sequential        | No                                                            |
| SingleTry      | One                                                     | Sequential        | Yes                                                           |
| BatchDefault   | Multiple                                                | Interleaved       | No                                                            |
| BatchTry       | Multiple                                                | Interleaved       | Yes                                                           |

### Sequential processing[​](#sequential-processing "Direct link to Sequential processing")

In `Single` modes, the Delegation Manager processes delegations sequentially:

1. For each delegation in the chain, all caveats' `before` hooks are called.
2. The single redeemed action is executed.
3. For each delegation in the chain, all caveats' `after` hooks are called.

### Interleaved processing[​](#interleaved-processing "Direct link to Interleaved processing")

In `Batch` modes, the Delegation Manager processes delegations in an interleaved manner:

1. For each chain in the batch, and each delegation in the chain, all caveats' `before` hooks are called.
2. Each redeemed action is executed.
3. For each chain in the batch, and each delegation in the chain, all caveats' `after` hooks are called.

`Batch` mode allows for powerful use cases, but the Delegation Framework currently does not include any `Batch` compatible caveat enforcers.
