Terms & Conditions
Last modified: Jan 11, 2026
1. Introduction
WeissFi (also referred to as "Weiss Finance") is a decentralized, non-custodial lending protocol built on the Sui blockchain. It allows users to borrow against their collateral with user-defined interest rates, ensuring capital efficiency and transparency. WeissFi offers:
  • Customizable Interest Rates - Borrowers set their own interest rates.
  • Multiple Collateral Types - Support for SUI, haSUI, and xBTC as collateral.
  • Savings Products - sDORI for earning yield and gDORI for liquidation protection.
  • Peg Stability Module (PSM) - Instant USDC ↔ DORI swaps to maintain price stability.
  • Optimized Liquidations - Stability Pools protect against sudden liquidations.
  • Efficient On-Chain Borrowing - Leveraging Sui's fast, low-cost transactions.
    • WeissFi is non-custodial, meaning no entity controls the funds within the Protocol. Users interact with smart contracts, and transactions are executed on-chain without intermediaries.
    2. Modification of Terms
    We reserve the right to modify these Terms at any time. Updated versions will be posted on the WeissFi website. Continued use of the Platform after modifications constitutes acceptance of the updated Terms.
    3. Eligibility
    To use WeissFi, you must:
  • Be at least 18 years old or the legal age in your jurisdiction.
  • Not be located in a sanctioned or restricted jurisdiction.
  • Use the Platform in compliance with applicable laws.
    • 4. Services Provided
    4.1 Borrowing
  • Users can deposit SUI, haSUI, or xBTC as collateral and borrow DORI (WeissFi's stablecoin).
  • Borrowers set their own interest rates (ranging from 0.5% to 25% annually).
  • Minimum loan amount is 50 DORI.
  • Loans are secured by collateral held in a "Vault."
  • Users can choose to receive DORI directly, or as yield-bearing sDORI or gDORI tokens.
    • 4.2 Liquidations
  • Maximum LTV is 83%. Liquidation occurs when LTV exceeds 83.33%.
  • Liquidated collateral is sent to the Stability Pool at a 10% discount.
  • Borrowers keep any surplus collateral after debt repayment.
  • If the Stability Pool is empty, debt is redistributed to other vaults. Vaults absorbing redistributed debt receive 20% of the liquidated collateral as compensation.
    • 4.3 Redemptions
  • If DORI trades below $1, redemptions allow users to exchange DORI for collateral at face value.
  • Borrowers with the lowest interest rates are affected first.
    • 4.4 Peg Stability Module (PSM)
  • Users can swap USDC to DORI and DORI to USDC at a 1:1 rate.
  • A small fee applies to PSM swaps to maintain protocol sustainability.
  • PSM helps maintain DORI's peg to $1 by providing instant liquidity.
    • 4.5 Savings (sDORI)
  • sDORI is a yield-bearing token representing a share of the Savings Pool.
  • sDORI earns 85% of all protocol interest payments.
  • No deposit or withdrawal fees, no lock-up period.
  • sDORI value increases over time through an exchange rate mechanism.
    • 4.6 Stability Pool
  • Users can deposit DORI directly into individual Stability Pools to earn liquidation rewards.
  • Stability Pool depositors absorb liquidations and receive discounted collateral in return.
    • 4.7 Guard Savings (gDORI)
  • gDORI is a yield-bearing token that automatically manages Stability Pool positions.
  • gDORI distributes deposits across multiple Stability Pools (90% SUI, 5% haSUI, 5% xBTC).
  • gDORI earns 15% of protocol interest plus 10% liquidation bonus on collateral.
  • An automated bot claims and sells liquidated collateral, converting it back to DORI.
  • Deposits and withdrawals are temporarily paused during liquidation processing.
  • No deposit or withdrawal fees, no lock-up period.

  • 100% of liquidation rewards go to Stability Pool depositors (gDORI holders).

    • 6. Risk Disclosure
    By using WeissFi, you acknowledge the following risks:
  • Smart Contract Risk: WeissFi operates on blockchain-based smart contracts that may contain vulnerabilities, bugs, or exploits that could result in total loss of funds.
  • Market Volatility: Collateral values can fluctuate rapidly, impacting LTV ratios and potentially triggering liquidations without warning.
  • Oracle Risk: WeissFi relies on external price feeds (oracles) to determine asset values. Oracle failures, delays, or manipulation could result in incorrect liquidations or other adverse outcomes.
  • Peg Stability Risk: DORI is designed to maintain a $1 peg but there is no guarantee it will always trade at $1. Market conditions may cause DORI to trade above or below its target price.
  • Third-Party Risk: WeissFi integrates with third-party services including DEX aggregators, liquid staking protocols (haSUI), and wrapped assets (xBTC). Failures or exploits in these external protocols could impact WeissFi users.
  • Network Risk: The Sui blockchain may experience congestion, downtime, or technical issues that could prevent users from executing transactions, including repaying loans or avoiding liquidation.
  • Regulatory Uncertainty: The legal status of decentralized finance (DeFi) varies by jurisdiction and may change at any time, potentially impacting WeissFi's services or your ability to use them.
  • Savings Risk: sDORI deposits are subject to smart contract risk and protocol risks.
  • Stability Pool Risk: Stability Pool depositors (including gDORI holders) receive collateral during liquidations, which may result in exposure to volatile assets.
  • gDORI Bot Risk: gDORI relies on an automated bot to claim and sell collateral. There is a risk of bot failure, delays, or unfavorable DEX quotes during collateral liquidation, even with slippage protection in place.
  • Total Loss Risk: You may lose all funds deposited or borrowed through WeissFi. Only use funds you can afford to lose entirely.
    • WeissFi is a non-custodial protocol. Users assume full responsibility for managing their funds and wallets. You are solely responsible for conducting your own research and due diligence before using any WeissFi services.
