## MyStacks

Portfolio infrastructure for tokenised finance. It uses per-user smart accounts
to separate user ownership from delegated portfolio activity.

## Portfolio

The assets held in a user's smart account.
Each portfolio follows the model defined by its subscribed strategy.

## Strategy

The manager's model portfolio of assets and target weights.
Multiple users can follow the same strategy while holding their assets separately.

## Manager

The party that chooses a strategy's assets and target weights.
A change to those weights applies at the next scheduled rebalance.
A manager has no withdrawal authority under the intended product model.

## Subscription

A user's enrolment in a strategy.
It connects the user's portfolio to the manager's allocation model.

## Smart account

A per-user account that holds assets and supports delegated execution.
The user retains ownership and can revoke automation or withdraw assets.

## Delegated permissions

Authority that a user grants for defined portfolio operations.
The user can revoke these permissions without giving up account ownership.

## Session signer

A signer used to authenticate requests allowed by delegated permissions.
It acts within a session and does not own the user's smart account.

## KMS

A key management service that protects the session signing key and signs requests.
It does not give MyStacks ownership of the user's account.

## Rebalance

A set of swaps intended to move a user's holdings towards a portfolio's target allocation.
The planned execution workflow applies manager allocation updates at the next applicable schedule boundary.
The [Manager API](/api-reference/stack-configuration#schedules) defines the accepted schedule presets.
Automated scheduled trading is still being built.

## Swap aggregators

Services that provide swap quotes and route data for portfolio transactions.
MyStacks passes selected quotes into its execution flow.

## Execution layer

The MyStacks layer that coordinates and submits portfolio transactions.
It works from routes selected using swap aggregator quotes.
