SuiStrategy

SuiStrategy is 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 the 1inch Fusion+ and 1inch Limit Order Protocol.

By reimagining convertible bonds and treasury growth mechanics in a modular Sui-native environment, SuiStrategy introduces SSTR, a token that offers leveraged exposure to SUI with managed downside risk and no forced liquidation. The protocol is also uniquely designed to enable cross-chain exposure to ETH and USDC through 1inch Fusion+, while offering sophisticated order types like TWAP, options, and range orders via the 1inch Limit Order system.

How It's Made

SuiStrategy is built on the Sui 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 Technologies

• Sui 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 integrated 1inch for:

  • 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 Benefits

By leveraging 1inch Fusion and Limit Order Protocol, we unlocked:

• Instant liquidity across chains for 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 Challenges

• We implemented a hybrid 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 a custom price oracle adapter to sync TWAP prices and protect bond redemptions from manipulation.
• Designed the note system to be ERC-20-like, but optimized for Sui’s object model.
