# Wallet Client actions reference

These actions extend the [Viem Wallet Client](https://viem.sh/docs/clients/wallet) to support [ERC-7710](https://eips.ethereum.org/EIPS/eip-7710) utilities.

## `sendTransactionWithDelegation`[​](#sendtransactionwithdelegation "Direct link to sendtransactionwithdelegation")

Sends a transaction to redeem delegated permissions according to the [ERC-7710](https://eips.ethereum.org/EIPS/eip-7710) specifications.

info

To use `sendTransactionWithDelegation`, the Viem Wallet Client must be extended with `erc7710WalletActions`.

### Parameters[​](#parameters "Direct link to Parameters")

See the [Viem sendTransaction parameters](https://viem.sh/docs/actions/wallet/sendTransaction#parameters). This function has the same parameters, and it also requires the following parameters:

| Name              | Type              | Required | Description                                                                                                                                                                                                                                                |
| ----------------- | ----------------- | -------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| delegationManager | Address           | Yes      | The address of the [Delegation Manager](/smart-accounts-kit/development/reference/glossary#delegation-manager)**Delegation Manager** The ERC-7710 component that validates and redeems delegations, including signature checks and caveat enforcer hooks.. |
| permissionContext | PermissionContext | Yes      | An encoded delegation chain (Hex) or a decoded delegation chain (Delegation[]) for redeeming delegations.                                                                                                                                                  |

## `redelegatePermissionContext`[​](#redelegatepermissioncontext "Direct link to redelegatepermissioncontext")

Creates a [redelegation](/smart-accounts-kit/development/reference/glossary#redelegation)**Redelegation** A delegation that passes on authority granted by a previous delegation. to a specific [delegate](/smart-accounts-kit/development/reference/glossary#delegate-account)**Delegate account** The account that receives delegated authority and can redeem a delegation under its constraints. from a delegation chain encoded as `Hex` or decoded as [Delegation](/smart-accounts-kit/development/reference/types/#delegation)`[]`.

The action returns [RedelegatePermissionContextReturnType](/smart-accounts-kit/development/reference/types/#redelegatepermissioncontextreturntype).
