What is Bond Farming of iZUMi Finance?

Bond Farming is the latest paradigm of on-chain financial derivatives innovation presented by iZUMi Finance and partners such as Cobo and Solv Finance.

Bond is issued by iZUMi Finance for on-chain financing, it combines the model of convertible bonds in traditional finance and the model of on-chain over-collateralized stablecoins. In the traditional financial industry, a convertible bond is a type of bond that can be converted into shares of the bond-issuing company, usually at a lower coupon rate.

iZUMi Finance issues convertible bond certificates in the form of iUSD(iZUMi Bond USD), a USD stablecoin, for institutions to provide on-chain funds. It is different from the well-known concept of USD stablecoin, and it abandons the systemic risk of algorithmic stablecoins, using transparent on-chain funds managed by smart contracts and multi-signature wallets as the over-collateral to back up the value of iUSD.

Bonds are issued through Solv Protocol, and as a convertible bond, it can support investors to convert bonds to iZi (iZUMi Governance Token) at a specific price at maturity, so that investors can also enjoy the potential investment return from iZi token appreciation.

Bond Farming Mechanism

The on-chain liquidity revenue captured by the iZUMi platform is the most direct support for Bond Farming investors’ returns. Bond Farming is a structured method of liquidity mining, providing risk-free earnings to bondholders. By guaranteeing the principal and interests paid to the investors, Bond Farming has set a paradigm shift in liquidity mining. The revenue generated by Bond Farming will first be used to repay the investors and then reward market makers.

Here iZUMi also draws on an important investment model in traditional finance — a multi-tiered investment product that provides a stable low return for investors with low-risk tolerance and a volatile high return option for investors with a high-risk appetite. In the Bond Farming designed by iZUMi Finance, institutional investors who provide investment funds directly through the purchase of bonds are said to be the investors who seek stable income in this system. The iZUMi project side and the professional market makers using iUSD are the investors who seek a high-risk appetite and high return profit margin.

This model not only greatly improves the efficiency of capital utilization, but also provides participating parties with investment options that meet their usage needs based on DeFi’s on-chain smart contracts, making it a cutting-edge innovation in the DeFi on-chain liquidity space.

Use cases for bond farming

  • For liquidity providers, Bond Farming lowers the risk of impermanent loss while giving a higher and stable profit.
  • For protocols, Bond Farming with iZUMi Finance could help them attract better on-chain liquidity on DEXs, with higher efficiency of Liquidity incentives, which is vital to the survival in a bear market. It’s a win-win situation for both the liquidity providers and the protocols if they adopt Bond Farming on iZUMi.

Repayment Guarantee & Securities

The funds raised were stored in the multi-sig wallet co-managed by Solv, iZUMi, and Cobo.

By using Cobo’s Cobo Safe, the wallet is able to be added to the Uniswap V3 BIT-ETH pool vault on iZUMi. At maturity, the fund will also be claimed through this wallet to maintain transparency for the use of the raised fund.

iZUMi collateralized 8 million USD worth of iUSD tokens.

iZUMi used the Treasury wallet to sign the Repayment Statement via EthSign. At maturity, iZUMi promises to repay the principal and the interest.

iZUMi’s smart contract has been audited by Certik and Blocksec.
