Search Aptos Examples Skill

Overview

This skill helps you find relevant examples in official Aptos repositories before writing new contracts. Always search examples first to follow established patterns.

• aptos-labs/daily-move/snippets/ — 17 curated educational examples covering design patterns, Move 2 features,

composable NFTs, and more

Core Workflow

• Fungible Assets: Coins, tokens, currencies
• DeFi: DEXs, AMMs, lending, staking
• Governance: DAOs, voting, proposals
• Marketplace: Trading, escrow, auctions
• Gaming: Items, characters, game logic
• Infrastructure: Registries, configs, utilities

Step 3: Review Example Code

What to look for:

1. Module Structure:

• How are imports organized?
• What structs are defined?
• How are error codes structured?

1. Object Creation:

• How are objects created?
• Which refs are generated?
• How is ownership managed?

1. Access Control:

• How is signer authority verified?
• How is object ownership checked?
• What roles/permissions exist?

1. Operations:

• How are transfers handled?
• How are updates secured?
• What validations are performed?

1. Testing:

• What test patterns are used?
• How is coverage achieved?

Step 4: Adapt Patterns to Your Use Case

Don't copy blindly - adapt:

1. Understand the pattern: Why is it structured this way?
2. Identify core concepts: What security checks are critical?
3. Adapt to your needs: Modify for your specific requirements
4. Maintain security: Keep all security checks intact
5. Test thoroughly: Ensure 100% coverage

Common Patterns from Examples

Pattern 1: Object Creation (from token_objects)

// From: token_objects/sources/token.move
public entry fun create_token(
    creator: &signer,
    collection_name: String,
    description: String,
    name: String,
    uri: String,
) {
    let constructor_ref = token::create_named_token(
        creator,
        collection_name,
        description,
        name,
        option::none(),
        uri,
    );
    // ... additional setup
}

Takeaway: Use named tokens for collections, create_object for unique items.

Pattern 2: Access Control (from dao)

// From: dao/sources/dao.move
public entry fun execute_proposal(
    proposer: &signer,
    proposal_id: u64
) acquires DAO, Proposal {
    let dao = borrow_global_mut(@dao_addr);
    let proposal = vector::borrow_mut(&mut dao.proposals, proposal_id);

    // Verify proposal passed
    assert!(proposal.votes_for > proposal.votes_against, E_PROPOSAL_NOT_PASSED);

    // Execute actions
    // ...
}

Takeaway: Verify state conditions before executing critical operations.

Pattern 3: Transfer Control (from fungible_asset)

// From: fungible_asset/sources/fungible_asset.move
public fun transfer(
    from: &signer,
    to: address,
    amount: u64
) acquires FungibleStore {
    // Verify sender has sufficient balance
    let from_store = borrow_global_mut>(signer::address_of(from));
    assert!(from_store.balance >= amount, E_INSUFFICIENT_BALANCE);

    // Deduct from sender
    from_store.balance = from_store.balance - amount;

    // Add to recipient
    let to_store = borrow_global_mut>(to);
    to_store.balance = to_store.balance + amount;
}

Takeaway: Check-effects-interactions pattern (verify, deduct, add).

ALWAYS Rules

• ✅ ALWAYS search examples before writing new contracts
• ✅ ALWAYS check both aptos-core (canonical) and daily-move (educational) repositories
• ✅ ALWAYS understand patterns before copying
• ✅ ALWAYS adapt patterns to your use case
• ✅ ALWAYS maintain security checks from examples
• ✅ ALWAYS reference which example you adapted from
• ✅ ALWAYS test adapted code thoroughly

NEVER Rules

• ❌ NEVER copy code without understanding it
• ❌ NEVER skip security checks from examples
• ❌ NEVER use deprecated patterns (resource accounts, address-based)
• ❌ NEVER assume examples are always up-to-date (verify against docs)
• ❌ NEVER mix V1 and V2 patterns
• ❌ NEVER include real private keys or credentials when adapting examples — use "0x..." placeholders

Search Checklist

Before writing contract code:

• [ ] Identified category (NFT, DeFi, DAO, etc.)
• [ ] Found 2-3 relevant examples in aptos-core
• [ ] Checked daily-move snippets for educational examples
• [ ] Reviewed module structure
• [ ] Identified security patterns
• [ ] Understood object creation patterns
• [ ] Noted access control mechanisms
• [ ] Checked test patterns
• [ ] Ready to adapt to my use case

Example Adaptation Workflow

Step-by-Step: Building NFT Collection

1. Search: Find token_objects example
2. Review Structure:

`` token_objects/ ├── sources/ │ ├── collection.move # Collection management │ ├── token.move # Token operations │ └── property_map.move # Metadata handling └── tests/ └── token_tests.move ``

1. Identify Key Patterns:

• Collection creation with create_collection
• Token minting with create_named_token
• Metadata storage using PropertyMap
• Transfer control with TransferRef

1. Adapt to Your Needs:

• Keep object creation pattern
• Keep security checks
• Add your custom fields
• Add your business logic
• Write comprehensive tests

1. Reference in Code:

``move // Adapted from: aptos-core/move-examples/token_objects module my_addr::custom_nft { // ... your implementation } ``
