Smart Contract Security Patterns in Move
I'm facing security implementation challenges in my DeFi protocol. Here's my specific challenge: resource struct Asset { value: u64, metadata: Metadata, } fun transfer( sender: signer, recipient: address, amount: u64 ): bool { let sender_account = borrow_global_mut(sender.address()); let asset = move_from(&mut sender_account, amount); transfer::transfer(asset, recipient); true } Could someone suggest a secure implementation pattern that prevents reentrancy attacks and unauthorized transfers while maintaining Move's resource guarantees?

Trouble Publishing Move Module onto Move VM with "MODULE_ADDRESS_DOES_NOT_MATCH_SENDER" Error
Hi everyone, I'm attempting to integrate Move VM into my custom network and encountering issues while trying to publish a Move module onto the Move VM. I've read that Move VM is "platform agnostic," and I'd appreciate guidance on the initial steps involved and whether this process involves significant effort. Additionally, I'm encountering a specific problem. I keep receiving the following error related to the Move stdlib dependency when attempting to publish a Move module: VMError { major_status: MODULE_ADDRESS_DOES_NOT_MATCH_SENDER, sub_status: None, message: None, exec_state: None, location: Undefined, indices: [(AddressIdentifier, 0)], offsets: [] } Below is a snippet of my code: fn build_and_publish_package(package_path: &str) { // Code for compiling the package and obtaining compiled units let instance = MoveVM::new(vec![]).unwrap(); let myresolver = MyResolver::new(); let mut new_session = instance.new_session(&myresolver); let sender_address = AccountAddress::ONE; let _ = new_session .publish_module_bundle(modules.clone(), sender_address, &mut UnmeteredGasMeter {}) .unwrap(); } In my Move.toml file, the stdlib is assigned the address 0x1. Importantly, I'm not using the stdlib anywhere in my code. Despite this, I'm consistently encountering the error mentioned above. Could someone please help me understand what could be going wrong or offer insights into troubleshooting this issue effectively?

Calling Functions from Move Module: Methods and Best Practices
Hello, I am trying to call a function (make_sword) from Move module with the address 0x4c6cccd6bc62eac9a9d023b6fa671d8f8c7eaf8ae7e67fae89d26883360dd89d in MOVE. Is it possible to call functions from different Move modules, and if so, what methods or approaches can I use? Are there any concepts similar to interfaces in Solidity for achieving this?

How to check if a specific function exists within a Move module at a given address?
I'm trying to figure out how to check if a specific function exists within a Move module at a given address in Move smart contract language, and if it does, call that function dynamically. Here's my scenario: I have a vector or array of addresses, and I need to determine whether a particular address has a specific function. If it does, I want to call that function dynamically. Is there a way to achieve this in Move? I've been struggling to find a solution, and any guidance would be greatly appreciated.

I'm facing performance issues
I'm facing performance issues in my DeFi protocol's resource management system. Here's my specific challenge: // Current inefficient implementation resource struct Asset { value: u64, metadata: Metadata, } // Multiple storage slots causing high gas costs let slot1 = move_from(&mut account.assets); I need to optimize storage and parallel processing while maintaining Move's security guarantees. Could you suggest an architecture that would reduce transaction processing time by 40% and storage costs by 30%, while preserving resource invariants during parallel execution?
