+# ERC-7715 permissions
+
+The Delegation Toolkit supports [ERC-7715](https://eips.ethereum.org/EIPS/eip-7715), which lets you request fine-grained permissions from a MetaMask user to execute transactions on their behalf.
+For example, a user can grant your dapp permission to spend 10 USDC per day to buy ETH over the course of a month.
+Once the permission is granted, your dapp can use the allocated 10 USDC each day to purchase ETH directly from the MetaMask user's account.
+
+ERC-7715 eliminates the need for users to approve every transaction, which is useful for highly interactive dapps.
+It also enables dapps to execute transactions for users without an active wallet connection.
+
+:::note
+This feature requires [MetaMask Flask 12.14.2](/snaps/get-started/install-flask) or later.

+
+## ERC-7715 permissions lifecycle
+
+The ERC-7715 permissions lifecycle is as follows:
+
+1. **Set up a session account** - Set up a session account to execute transactions on behalf of the MetaMask user.
+  It can be a [smart account](smart-accounts.md) or an externally owned account (EOA).
+
+2. **Request permissions** - Request permissions from the user.
+  MetaMask supports multiple ERC-7715 [permission types](#permission-types).
+
+3. **Set up a Viem client** - Set up a Viem client (the client type depends on the session account type) to redeem permissions.
+
+4. **Redeem permissions** - Once the permission is granted, the session account redeems the permission.
+
+See [how to perform executions on a MetaMask user's behalf](../guides/erc7715/execute-on-metamask-user-behalf.md) to get started with the ERC-7715 lifecycle.
+
+## Permission types
+
+The Delegation Toolkit currently supports the following types of ERC-7715 permissions:
+
+- **Native token permissions** - Define how dapps can use users' native tokens.
+
+- **ERC-20 token permissions** - Define how dapps can use users' ERC-20 tokens.
+
+## ERC-7715 permissions vs. delegation
+
+Requesting and redeeming ERC-7715 permissions differ from [creating and redeeming delegations](delegation/index.md).
