(Coming soon) Trade with Incentives: To increase the liquidity of iUSD, iZiSwap will incentivize iUSD-related trading pairs, including farming incentives and trading fee cashback. ### Value support for iUSD Every week iZiSwap’s 25% revenue will be sent to iZUMi Treasury and used to buy back iUSD in the secondary market until the price of iUSD gets above 0.996 USDT. If it lasts for 4 consecutive weeks that the price of iUSD gets below 0.996 USDT, iZUMi is committed to using the treasury fund to buy back and burn iUSD within the next week. The supply of iUSD will never exceed the total value of iZUMi Treasury to guarantee safety and transparency. ### On-chain Security iZUMi Bond Farming’s security is fully backed by Cobo Safe. Cobo Safe is DaaS (DeFi-as-a-Service) in the smart contract-based environment, powered by Gnosis Safe. It solves the limitations of existing multi-signature wallets by letting teams collaborate in accessing DeFi protocols without sacrificing efficiency for security. The focus is on role delegation and risk management through limiting operators’ access to protocols, actions and even controlling the parameters to granular trading pairs and limits. This risk-mitigated team collaboration supports custom workflows and creates a more efficient multi-signature access to DeFi where asset owners can give pre-defined operational controls to their team in a trust-less environment. ### iUSD Token info **Type**: ERC-20 Token on Ethereum **Ticker**: iUSD Token Addresses: **Ethereum Contract**: 0x0A3BB08b3a15A19b4De82F8AcFc862606FB69A2D **BNB Chain Contract**: 0x0A3BB08b3a15A19b4De82F8AcFc862606FB69A2D **Polygon Contract**: 0x0A3BB08b3a15A19b4De82F8AcFc862606FB69A2D **Arbitrum Contract**: 0x0A3BB08b3a15A19b4De82F8AcFc862606FB69A2D **zkSync Contract:** 0x1382628e018010035999A1FF330447a0751aa84f **Mantle Contract:** 0x0A3BB08b3a15A19b4De82F8AcFc862606FB69A2D **Linea Contract:** 0x0A3BB08b3a15A19b4De82F8AcFc862606FB69A2D **Base Contract:** 0x0A3BB08b3a15A19b4De82F8AcFc862606FB69A2D **iZUMi Treasury Ethereum**: 0xe3071f78fbc34c0043820229283cc3b5621b75dc --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
