When you see a MoveAbort error on the Sui Network, it means your Move smart contract has hit an explicit abort statement, usually because a condition failed during execution. You typically trigger this kind of error when a assert! fails or when a function explicitly returns an abort with a custom error code. This kind of error helps ensure contract logic halts before any unintended state changes occur. To debug it effectively, you need to understand the exact location, abort code, and which module triggered it.

To start debugging, use the Sui CLI with --gas-budget set high enough to avoid unrelated failures. Deploy your contract to localnet or testnet using:

sui move build
sui client publish --gas-budget 100000000

If an error occurs when calling a function, you’ll see a response like this:

Error: MoveAbort: code 0x1::module::ERR_INSUFFICIENT_BALANCE

This tells you which module and code caused the failure. Match the code to constants defined in your Move module like this:

const E_INSUFFICIENT_BALANCE: u64 = 0;

In development, always wrap risky logic with assert! and custom error codes for clarity:

assert!(balance >= amount, E_INSUFFICIENT_BALANCE);

One unique thing about Sui is its object-based storage and ownership model. Unlike EVM chains that operate with account balances and mappings, Sui tracks ownership of specific on-chain objects, making MoveAbort more likely if ownership or borrowing rules are violated. So always validate object references, ensure correct capabilities (e.g., shared, immutable, owned), and use borrow_global or borrow_object correctly.

To trace bugs more efficiently, use sui move test locally:

sui move test

And log events inside your functions using:

emit<YourEvent>(YourEvent { field: value });

To avoid MoveAbort, follow best practices like checking object ownership, not assuming availability of resources, handling optional types safely, and using assert! defensively.

Transaction block example:

sui client call --function transfer --module wallet --package 0xabc123 --args 0xrecipient_id 1000 --gas-budget 10000000

By understanding how Move handles resources and enforcing rules through aborts, you reduce the risk of logic bugs and ensure your smart contract behaves safely in production.

It looks like you've provided a template for a question rather than a specific topic! Please tell me which particular Sui Network mechanism or feature you'd like a detailed explanation of. Once you specify the topic (e.g., 'Sui Objects', 'Transaction Sponsorship', 'Kiosk', 'Dynamic Fields', 'Programmable Transaction Blocks', etc.), I can provide the comprehensive breakdown you're looking for, including relevant CLI usage, Move code, architectural concepts, and how it differs from EVM chains, helping you apply it to your project effectively.
