Advanced Topics

Information in the Advanced Topics section covers coding practices, useful features, and other developer-focused considerations that might arise as you continue your development journey on Sui. The topics in this section aren't necessarily more difficult than other topics, but they include subjects you might not encounter or need to consider until you're developing more advanced solutions on the Sui network.

Migrating to Move 2024

New features are becoming available to Move in 2024. These features are opt-in, so existing code will continue to function as expected. If you want to use these features in code you've already written, however, there are some steps you must take and breaking changes to be aware of to migrate to Move 2024.

Build Your First Custom Indexer

Establishing a custom indexer helps improve latency, allows pruning the data of your Sui full node, and provides efficient assemblage of checkpoint data.

On-Chain Randomness

Randomness is a valuable tool to simulate chance on chain, but can also expose flaws in your logic. Understanding the vulnerabilities and accounting for them can mitigate the threat exposure for your smart contracts.

Querying Sui RPC with GraphQL

Object-Based Local Fee Markets

Object-based local fee markets limit the rate of transactions writing to a single shared object, preventing the network from becoming overloaded with checkpoints that take too long to execute.
