Building on Sui is exciting — its object-centric model opens up new design patterns and faster parallelism. But ⚠️ new models = new mistakes. Ownership bugs, escrow leaks, or careless admin keys can cause costly losses. This guide gives you a step-by-step security checklist 📝 plus a practical marketplace example to show how to avoid the most common pitfalls. ✅ 1) The Sui Security Checklist 🔑 Least Privilege • Don’t rely on a single global “admin key.” • Use capability objects for authority. • Guard critical admin powers with multisig or on-chain governance. ⚖️ Atomic Escrow Transfers • Always escrow assets inside dedicated Listing objects. • Use Programmable Transaction Blocks (PTBs) for atomic swaps → prevents front-running and double spends. 🛡️ Validate All Inputs • In Move, check vector lengths, bounds, and constraints. • Validate deserialization and reject malformed objects. • Never assume input safety just because the object exists on-chain. 🧪 Test & Fuzz Aggressively • Write negative tests: invalid inputs, concurrent updates, gas exhaustion. • Add fuzzing for unexpected transaction flows. • Automate in CI to catch regressions early. 🔐 Key Management • Store admin keys in hardware wallets. • Use multisig for governance actions. • Rotate keys when team members leave. 👀 Audits & Incentives • Get critical Move modules audited. • Launch a bug bounty program for community testing. • Remember: external eyes catch what you miss. 🏪 2) Example in Practice: A Safe Marketplace Here’s how to apply the checklist in a marketplace dApp: • Escrow NFTs safely: Seller moves the NFT into a Listing object. The marketplace contract cannot take funds without seller’s approval. • Handle royalties correctly: Compute royalties inside the PTB, ensuring correct fee splitting (watch out for rounding!). • Reentrancy? Not here: Move’s resource model prevents copying/reentrancy by design. Still, test all flows to ensure no logical loopholes. 📚 Sources & Further Reading • Sui Docs: Concepts & Transactions • Sui Whitepaper (object-centric model) • Mysten Labs TypeScript SDK Docs • Move Book • Sui GitHub Repo ✨ Takeaway: On Sui, security is less about EVM-style reentrancy bugs and more about ownership, authority, and atomicity. If you follow the checklist, you’ll reduce your attack surface dramatically while keeping user assets safe.

You start by installing the Sui CLI and the Move toolchain so you can build and publish code, then you run sui client active-address to confirm a working keypair and hit the faucet to get test SUI, after which you create a fresh Move package with the template so you don’t fight folder structure, then you edit a single module to define a simple object with an owner field and a few methods like init, update, and transfer so you can exercise Sui’s object model quickly, next you compile with sui move build and fix any errors the compiler shows because that is your fastest feedback loop, then you publish with sui client publish --gas-budget and grab the package and module IDs from the output so you can call functions, after that you call your init entry function to mint an object and copy the object ID from the transaction effects, then you run sui client object to see version, owner and fields so you confirm the chain wrote what you expect, if you run into “insufficient gas” you shrink the gas budget or request more test SUI since every publish and call costs gas, if you get “module not found” you probably used the wrong package ID or forgot to rebuild, if your transfer fails with a capability error you likely made the object shared when you meant owned or you forgot to pass the correct argument shape, once the basics work you script the flow in a shell or JavaScript script so one command builds, publishes, mints, updates and transfers, which saves time and prevents typos, and finally you push this minimal example to a repo so teammates can clone and run the same steps in minutes; by treating the object as the unit of thinking rather than a single global contract you align how you code with how Sui stores state, which keeps your mental model clean and prevents hard-to-debug reentrancy or global-state races that you might meet on other chains, and because Sui parallelizes owned-object transactions you also see fast confirmation while you iterate which makes onboarding much nicer.

⸻ Introduction: The Enterprise Data Sharing Dilemma Enterprises today are more interconnected than ever, yet securely sharing data between organizations remains one of the toughest challenges. Whether it’s supply chains, insurance networks, or financial consortia, companies struggle with: • Lack of data interoperability • Fear of data misuse or breaches • Redundant audits and compliance overhead • Siloed and outdated information pipelines Blockchain, especially Sui, offers a path forward by enabling verifiable, modular, and permissioned data exchange—with full traceability and logic enforcement baked in. ⸻ Why Sui for Cross-Enterprise Data Sharing? Sui stands out due to its object-centric architecture, scalable design, and support for secure identity verification. 🔍 Sui’s Unique Advantages: Feature Relevance to Data Sharing Object-based data model Each data packet has a unique identity, lifecycle, and owner Access control via Move Control who can read, write, or modify shared data zkLogin for enterprise ID Authenticate with existing cloud credentials securely Immutable audit logs Full traceability of who shared or accessed data Modular contract logic Tailor data permissions, schemas, and triggers ⸻ Real-World Use Case: Manufacturing & Logistics Let’s examine a scenario where multiple manufacturers and logistics providers need to share shipping status, production quality data, and inventory levels—without compromising privacy or control. Traditional Problems: • Data silos and delays across systems (e.g., SAP, Oracle) • Mistrust over data accuracy • Inefficient manual reconciliations Sui-Enabled Solution: • Each shipment becomes a Sui object with a dynamic status • Suppliers, logistics, and retailers have scoped permissions • Events are emitted at every stage: packaged, shipped, delivered • All parties verify states via on-chain queries or off-chain APIs ✅ Result: Real-time visibility with full audit trail, reducing disputes and delivery errors. ⸻ Architecture: Building a Cross-Enterprise Protocol on Sui 🔧 On-Chain: • DataObject: encapsulates the shared information (e.g., shipment ID, temperature logs, certs) • AccessControlModule: manages roles and permissions (who can write, view, or transfer ownership) • AuditModule: logs key events, state changes, or metadata updates 🔒 Example Move Snippet: module logistics::AccessControl { struct Permission has key { data_id: ID, viewer: address, can_edit: bool, } public fun grant_view_permission(data_id: ID, viewer: address) { move_to(&viewer, Permission { data_id, viewer, can_edit: false }); } public fun update_data(data: &mut SharedData, viewer: &Permission) { assert!(viewer.can_edit, "Viewer lacks write permission"); data.status = "Updated"; } } ⸻ Data Privacy and Zero-Knowledge Identity Not all data should be visible to everyone. Sui enables selective data exposure through: • zkLogin for authentication without revealing user identity • Encryption of object fields stored on-chain • Off-chain storage pointers for GDPR-sensitive data • Selective permission grants using access tokens or NFT-based credentials This ensures enterprises can collaborate securely while retaining privacy and control over sensitive data. ⸻ Governance Models for Shared Protocols When multiple organizations co-manage a protocol, it’s essential to define: Aspect Options with Sui Access Governance Role-based access (admin, reader, editor) Contract Upgrades Multi-sig approvals or DAO-based voting Dispute Resolution On-chain arbitration modules or pause logic Jurisdiction Rules Regional modules with legal context Move allows you to encode these governance rules as modular contracts, reducing ambiguity and enforcing compliance programmatically. ⸻ Case Study: Insurance Consortium Sharing Claims Data Scenario: Three insurers form a consortium to reduce fraud by sharing claims data. Problem: • Duplicate claims across companies • Manual reconciliation taking weeks • Legal hurdles for data exchange Sui-Based Solution: • Shared “ClaimObject” created upon submission • AccessControlModule grants limited read/write access to partner insurers • Events and state changes (e.g., approved, flagged) tracked on-chain • Only anonymized claim data (e.g., car damage + timestamp) is shared Outcomes: • 35% drop in duplicate claims • Instant validation by partners • Fully auditable claims review process ⸻ Cross-Chain and Off-Chain Integration Sui data-sharing protocols can interoperate with: • Off-chain systems using APIs, oracles, and secure data bridges • Other chains via Sui’s evolving interoperability framework (e.g., LayerZero, Wormhole) For example, an energy grid can share on-chain carbon credits across both Sui and Polygon, while preserving audit logs in Sui’s storage. ⸻ Challenges and Mitigation Strategies Challenge Sui-Based Solution Legal restrictions on data transfer Use zkLogin + jurisdiction-aware modules Varying tech maturity of partners Build API wrappers and dashboards for low-code access Versioning of shared schemas Use object version control and upgradeable contracts Need for off-chain validation Combine oracles with on-chain event proofs Sui gives enterprises flexibility to design around real-world constraints, without compromising security or control. ⸻ Conclusion: Sui as the Trust Layer for Enterprise Collaboration Data is the new oil—but only when shared, trusted, and actionable. With Sui, enterprises can: • Encode collaboration logic directly in smart contracts • Control who sees and edits sensitive data • Track, audit, and enforce protocol rules automatically • Build scalable, secure, and privacy-respecting data pipelines As more industries demand trust-minimized, programmable data exchange, Sui provides the ideal infrastructure for building shared, tamper-proof ecosystems.

❓ Problem: Many devs unknowingly bottle-neck their Sui apps by cramming multiple users’ state into one big “global” object. The result? 🚧 Poor throughput and painful contention. 💡 Why this happens: Sui is built for parallel execution — but only if your design allows it. Touching a single shared object kills concurrency. 🎯 Goal: Here’s a scaling playbook with rules, examples, and a checklist to help you unlock Sui’s true power. 🧩 1) Split Hot State into Many Small Objects Create per-user / per-item objects instead of global registries. Example: ❌ Bad: A single game object holding all players’ inventories. ✅ Good: Each player has their own inventory object. 🚀 Benefit: Sui can execute transactions in parallel with no contention. 📚 docs.sui.io 🚫 2) Avoid Global Counters or Shared Objects Global counters = 🚦traffic jams. Alternatives: Off-chain counters with periodic on-chain checkpoints. Sharded counters → e.g., 1 per region or partition, aggregated later. Result: Higher throughput, fewer conflicts. 📡 3) Use Events & Indexers for Aggregation Don’t burn gas doing heavy on-chain aggregation. Instead: Emit events 📢. Use an off-chain indexer to compile data for the UI. 🔑 Pattern: On-chain = state changes only. Off-chain = fast queries. 🧪 4) Concurrency Testing Stress test locally with parallel transactions hitting disjoint objects. Watch out for: Object version conflicts 🔄. Bottlenecked objects 📉. Fix by redesigning objects until throughput looks healthy. 📚 Sui GitHub ✅ Quick Scaling Checklist [ ] Break global state → per-user/per-item objects. [ ] Replace global counters with off-chain or sharded solutions. [ ] Use events + indexers for fast aggregation. [ ] Run concurrency tests to validate design. ⚡ Bottom line: Sui rewards parallelism-first design. Think many small objects → not one big one. If you respect the scheduler, your app can scale to thousands of TPS without breaking a sweat 💪.

❓ Problem: Debugging Move on Sui feels like searching for a needle in a haystack. Errors are cryptic, stack traces look alien, and reproducing bugs is tough. 💡 Why this happens: On-chain failures behave differently than traditional code errors. Without a clear debug loop, fixing them can feel like guesswork. 🎯 Goal: Equip you with tools, logs, and workflows to reproduce, debug, and fix issues with confidence. 🛠️ 1) Use Local Deterministic Devnets Spin up a single-node local devnet with fixed seed accounts for reproducibility. Commands like sui start or run-local-network.sh work great. Benefit:** Test without network noise! 📚 docs.sui.io 🧪 2) Unit Tests & Move Test Harness Run: sui move test Write tests for edge cases & expected reverts. Faster feedback = faster bug squashing. 🐛 🔍 3) Transaction Simulation & Logging Simulate before you submit** using SDK APIs. Inspect transaction effects to see: ✅ Created objects ✅ Mutated objects ✅ Deleted objects Read emitted events to trace what happened step-by-step. 📚 Mysten Labs TS SDK Docs 📄 4) Use Node Logs & Debug Flags Run nodes with verbose logging to get detailed execution traces. Check Sui repo for debug flag usage. If you can, peek at validator logs for tricky issues. 🪜 5) Step-by-Step Debug Flow Reproduce locally with the same object IDs/inputs. Write a sui move test that mimics the transaction. Inspect transaction effects & logs. Add assertions to pinpoint wrong state changes. Fix → Test → Repeat until stable.
