Why Sui?
Choosing the Right Blockchain
Building a savings-focused dApp requires a blockchain that prioritizes speed, security, low cost, and user experience. After evaluating multiple Layer 1 and Layer 2 solutions, we chose Sui Network as the foundation for Money Race. Here's why.
Key Reasons
1. Parallel Transaction Processing
Sui uses a unique object-centric model that enables parallel execution of independent transactions. Unlike traditional blockchains that process transactions sequentially, Sui can handle thousands of transactions simultaneously.
Why it matters for Money Race:
Multiple users can deposit into different rooms at the same time without congestion
Room creation, deposits, and reward claims all execute in parallel
No bottlenecks during peak activity periods
2. Sub-Second Finality
Sui achieves transaction finality in under 1 second — users don't have to wait for block confirmations.
Why it matters for Money Race:
Deposits are confirmed instantly
Reward claims happen in real-time
The user experience feels as fast as Web2 applications
3. Low and Predictable Gas Fees
Sui's gas model keeps transaction costs extremely low and predictable, making it feasible to sponsor gas for all users.
Why it matters for Money Race:
We can offer 100% gasless transactions — users pay zero gas fees
Backend sponsors all gas costs without significant overhead
Users only need USDC to participate, no native SUI tokens required
4. zkLogin — Web2-Friendly Authentication
Sui's zkLogin allows users to authenticate using their existing Google accounts through zero-knowledge proofs, without exposing any personal data on-chain.
Why it matters for Money Race:
No wallet setup, no seed phrases, no browser extensions
One-click login with Google — as easy as signing into any Web2 app
Lowers the barrier for non-crypto users to enter DeFi
User privacy preserved through zero-knowledge cryptography
5. Move Language — Safety by Design
Sui uses the Move programming language, originally developed at Meta (Facebook) for the Diem project. Move is designed with safety as a first-class priority.
Key safety features:
Linear type system — Assets cannot be accidentally duplicated or destroyed
Resource-oriented programming — Digital assets are treated as real resources with strict ownership rules
Built-in formal verification — Easier to prove contract correctness
No reentrancy attacks — The language design eliminates an entire class of vulnerabilities common in Solidity
Why it matters for Money Race:
User funds are protected at the language level
Smart contract bugs that could cause fund loss are structurally prevented
Greater confidence in the security of deposits and reward distribution
6. Rich DeFi Ecosystem
Sui has a growing and mature DeFi ecosystem with battle-tested protocols:
Scallop
Lending
Conservative yield generation
Navi Protocol
Lending
Stable yield with low risk
Cetus
DEX & Liquidity
Balanced to aggressive strategies
Turbos Finance
AMM
Diversified yield farming
Kriya
DEX
High-yield trading strategies
Aftermath Finance
Liquid Staking
Additional yield layer
This ecosystem enables our AI (EigenAI) to recommend and allocate funds across multiple protocols based on user risk preferences.
7. Programmable Transaction Blocks (PTBs)
Sui's Programmable Transaction Blocks allow multiple operations to be composed into a single atomic transaction.
Why it matters for Money Race:
Deposit + room state update + leaderboard update can happen in one transaction
Reduces complexity and gas costs
Ensures all-or-nothing execution — no partial state changes
8. Sponsored Transactions
Sui natively supports sponsored transactions, where a third party (our backend) can pay the gas fees on behalf of the user.
Why it matters for Money Race:
Built-in support for our gasless UX — no hacky workarounds needed
Clean multi-signature flow: user signs intent, backend adds gas sponsorship
Reliable and well-supported by the Sui SDK

Summary
Sui isn't just a fast blockchain — it's a blockchain designed for real-world user experience. The combination of zkLogin, sponsored transactions, sub-second finality, and the Move language makes it the ideal platform for Money Race's mission: making savings accessible, fun, and rewarding for everyone.
"We didn't choose Sui because it's trendy. We chose it because it's the only blockchain where we can deliver a truly gasless, Web2-like savings experience without compromising on security or decentralization."
