Key Modules

Account Management

aptos_framework::account

Manages account creation, authentication key rotation, and signer capabilities.

use aptos_framework::account;

// In tests
#[test_only]
fun setup(account: &signer) {
    account::create_account_for_test(signer::address_of(account));
}

Token Standards

aptos_framework::coin

The legacy fungible token standard (see Coin (Legacy)).

aptos_framework::fungible_asset

The modern fungible token standard (see Fungible Asset).

aptos_framework::primary_fungible_store

Primary stores for fungible assets, automatically created per account.

Object Framework

aptos_framework::object

The object model for creating and managing on-chain objects (see Object Model).

use aptos_framework::object::{Self, Object, ConstructorRef};

fun create_my_object(creator: &signer): ConstructorRef {
    object::create_object(signer::address_of(creator))
}

Events

aptos_framework::event

Event emission for indexing and observability.

use aptos_framework::event;

#[event]
struct MyEvent has drop, store {
    value: u64,
}

fun emit_event() {
    event::emit(MyEvent { value: 42 });
}

Randomness

aptos_framework::randomness

On-chain randomness for games, lotteries, and fair selection.

use aptos_framework::randomness;

#[randomness]
entry fun random_action(account: &signer) {
    let random_number = randomness::u64_integer();
}

Governance and Staking

aptos_framework::aptos_governance

On-chain governance for protocol upgrades and parameter changes.

aptos_framework::staking

Validator staking and delegation.

Utilities

aptos_framework::timestamp

Access the current blockchain timestamp.

use aptos_framework::timestamp;

fun get_current_time(): u64 {
    timestamp::now_seconds()
}
