SuiStrategy

Problem Statement

SuiStrategyis an autonomous, composable treasury protocol on the Sui network designed to accumulate SUI through structured debt and token-based strategies, while enabling cross-chain exposure and advanced financial primitives via integration with the1inch Fusion+and1inch Limit Order Protocol.By reimagining convertible bonds and treasury growth mechanics in a modular Sui-native environment, SuiStrategy introducesSSTR, a token that offers leveraged exposure to SUI with managed downside risk and no forced liquidation. The protocol is also uniquely designed to enablecross-chain exposure to ETH and USDCthrough 1inch Fusion+, while offering sophisticated order types likeTWAP,options, andrange ordersvia the 1inch Limit Order system.

Solution

How It's MadeSuiStrategy is built on theSui blockchain, leveraging its high-performance infrastructure and object-based architecture to design efficient and composable DeFi strategies. Here’s a breakdown of the technologies and integrations we used:Core TechnologiesSui Smart Contracts (Move Language)We wrote all protocol logic using Move, Sui’s native language, to create and manage long/short bonds, note issuance, and automated redemption logic. Move’s asset-centric model allowed us to handle bond ownership and transformations efficiently.1inch Fusion & Limit Order Protocol (Cross-chain)We integrated1inchfor:Fusion Swaps– enabling secure, MEV-resistant cross-chain swaps between SUI ↔ ETH, USDC, etc., which is essential for real-world composability.Limit Order Protocol– extending support for custom DeFi features such as scheduled conversions, TWAPs, and options-like behavior on note redemptions or bond settlements.1inch Integration BenefitsBy leveraging1inch FusionandLimit Order Protocol, we unlocked:Instant liquidity across chainsfor SUI, boosting capital efficiency.Advanced strategies, such as conditional swaps and timed redemptions.Security and gas savings, thanks to 1inch’s backend infrastructure and RFQ system.Notable Hacks or ChallengesWe implemented ahybrid execution model: combining on-chain logic with off-chain trigger execution (using webhooks and crons) for time-based strategies, which helped bypass current limitations in Move-based cron scheduling.Used acustom price oracle adapterto sync TWAP prices and protect bond redemptions from manipulation.Designed the note system to beERC-20-like, but optimized for Sui’s object model.
