# Switchboard Aptos Feeds Skill

## Purpose

Use Switchboard on-demand feeds on Aptos:

* crank/update feeds client-side (pull model)
* consume verified results in Move
* enforce freshness/deviation policies in app logic

## Dependencies

Use exact pins from the [SDK Version Matrix](/tooling/sdk-version-matrix.md).

* `@switchboard-xyz/aptos-sdk@0.1.5`
* `@switchboard-xyz/common@5.7.0`
* `@aptos-labs/ts-sdk@6.1.0`

## Preconditions

* `OperatorPolicy` exists (Aptos network, signer custody, RPC allowlist).

## Inputs to Collect

* network (mainnet/testnet)
* RPC endpoint
* `crossbarUrl` (default: `https://crossbar.switchboard.xyz`)
* aggregator/feed identifiers (addresses/object IDs)
* safety policy (staleness/deviation/min responses) only if risk-sensitive

## Invariants

* Pull-based: client must crank/update feeds to keep data fresh.
* Ensure update action is executed before reading within the same flow (where applicable).

## Playbook (high-level)

* Off-chain:
  * fetch/update payload(s) for the feed/aggregator
  * submit transaction to run the update action (or include it in the same entry call if supported)
* On-chain:
  * read current result + timestamp
  * enforce staleness and deviation vs last stored value

## Minimal Example

```move
use aptos_framework::aptos_coin::AptosCoin;
use aptos_framework::object::{Self, Object};
use switchboard::aggregator::{Self, Aggregator, CurrentResult};
use switchboard::update_action;

public entry fun read_feed(account: &signer, update_data: vector<vector<u8>>) {
    update_action::run<AptosCoin>(account, update_data);
    let feed: Object<Aggregator> = object::address_to_object<Aggregator>(@0xSomeFeedAddress);
    let current: CurrentResult = aggregator::current_result(feed);
    let _price = aggregator::result(&current);
}
```

## Outputs

Produce an `AptosFeedIntegrationPlan` including:

* identifiers and network alignment checks
* crank strategy (if requested)
* Move consumption point and validation policy (if requested)
