MandateFactory

MandateFactory is a UX orchestrator. It bundles the two steps of attaching a configurable permission — template.configure(...) then kernel.registerPermission(...) — into a single transaction, and forwards the registration fee with an automatic refund of any excess. License: GPL-2.0-or-later.

It holds no trust

The factory has no privilege. Every inner call is independently signature-authenticated:

• configure carries an EIP-712 signature from the account's Permission Signer (verified by the template against the kernel).

• registerPermission carries an EIP-712 signature from the Permission Signer (verified by the kernel).

So the factory's only value is bundling, fee forwarding, and a canonical entry point for tooling. Anyone can deploy a template implementing IConfigurablePermission and use it with the factory immediately — no allowlist, no registry. Its receive() accepts ETH only from the kernel (the fee refund), preventing balance-inflation games against the refund accounting.

Operations

Function	What it does
attach	configure one template, then registerPermission, one tx; refunds fee excess.
attachBatch	configure N templates, then registerPermissions atomically.
reconfigure	re-configure a template's params for an account (no kernel touch).
replace	configure a new template, then replacePermission (atomic kernel swap).
deployAndAttach	clone a standalone template (EIP-1167), initialize it, then registerPermission — one tx.
detach / detachBatch	revokePermission(s) for an account.

Deterministic clones

deployAndAttach deploys an EIP-1167 minimal-proxy clone of a logic contract via Clones.cloneDeterministic, with the salt namespaced by msg.sender (keccak256(abi.encode(msg.sender, salt))) to prevent cross-caller salt squatting. Predict the address beforehand with predictCloneAddress(impl, salt) — from the same EOA that will send deployAndAttach, because of the namespacing. After init, a liveness check (CloneInitializable.initialized()) guards against a clone that failed to initialize.

Events

Attached, BatchAttached, Reconfigured, Replaced, Detached, BatchDetached, and CloneDeployedAndAttached(account, impl, clone, salt).

Using the factory is optional. You can always call the kernel's registerPermission / replacePermission / revokePermission directly — the factory just saves a transaction when a template also needs configuring.
