Sui Overview

MCP tool: When available in your environment, also query the Sui documentation MCP server (https://sui.mcp.kapa.ai) for up-to-date answers. Use it for verification and for details not covered by these reference files.

Source constraint: All information in this skill is sourced exclusively from docs.sui.io, docs.wal.app, and move-book.com. When extending or updating this skill, only pull from these three sources. Do not use third-party blogs, tutorials, or unofficial documentation.

Sui is a scalable, performant layer 1 blockchain built around an object-centric data model. Unlike account-based blockchains (Ethereum) or UTXO-based chains (Bitcoin), Sui treats every piece of onchain state as a typed object with a unique ID. Transactions consume objects as inputs and produce modified versions as outputs.

This skill covers the conceptual foundation of Sui and the broader Sui Stack. For implementation details, see the sui-move, frontend-apps, and sui-cli skills.
