# Advanced dapp permissions

ERC-7715 lets a dapp request reusable but constrained authority instead of
asking you to approve every individual action.

## Requirements

WalletChan currently supports this for private-key and seed-phrase accounts
already delegated to WalletChan's compatible default smart account. Bankr,
Ledger, view-only, and Safe do not grant these permissions.

Granting requires a master or passkey-master session. An agent password cannot
issue new delegated authority.

## What a request can contain

WalletChan supports policy-approved forms such as:

* One-time native or ERC-20 allowance.
* Periodic spending allowance.
* Streaming allowance/rate.
* Token-approval revocation capability.

The review shows the requesting app and reason, asset/current balance, delegate,
allowed methods, amount/exposure, cadence, start, and expiration.

## Edit within the safe envelope

When the request allows editing, you can reduce or adjust:

* Per-use, periodic, or total limits.
* Stream rate and display unit.
* Start and expiry time in UTC.
* Allowed methods.
* Approved cleanup/expiration parameters.

WalletChan never lets the edit exceed the authority envelope validated by the
background policy.

## Grant or reject

Granting is an onchain authority change. Rejecting leaves the account
unchanged. View-only requests remain reject-only.

## View and revoke

Open the local account's settings to see permissions grouped by origin. Revoking
creates an onchain transaction, so it requires signing and gas. Disconnecting
the dapp alone does not revoke the permission.

## Read Advanced

Advanced details include exact permission manager, caveats, delegate, and raw
JSON. If the plain-language summary and exact details disagree, reject.
