Delegation Manager

The Delegation Manager is a core component of the Delegation Framework. It validates delegations and triggers executions on behalf of the delegator, ensuring tasks are executed accurately, and securely.

See the delegation flow for a full overview of how delegations are created, validated, and redeemed.

Execution modes

When redeeming a delegation using 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:

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

In Single modes, processing is sequential:

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

In Batch modes, processing is interleaved:

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.
