Bond Issuance Announcement #7: IZI Bond Voucher

This August 17, iZUMi Finance will issue its 4th IZI Bond Voucher on Solv IVO Marketplace–BNB Chain, at an 18% APY–4 times CAKE’s flexible staking on Pancakeswap at a 4% APY. iZUMi plans to raise $1 million USD in CAKE from the sale to provide liquidity to its native DEX, iZiSwap.

Overview of the IZI Bond Voucher

Expected returns

The exact amount and currency in which the IZI Bond Voucher repays the investors at maturity are subject to the IZI token’s 7-day average price before the maturity date.

At maturity, if IZI’s market price is above 0.015 CAKE, the Bond Voucher will be converted to IZI tokens automatically to maximize bondholders’ profit (in USD). If the bondholders do not wish to exercise the option, they may return the Bond Voucher to iZUMi’s wallet address within 48 hours after maturity and receive their principal and accrued interest in CAKE token as repayment.

Use of funds

The net proceeds from the sale of this IZI Bond Voucher will be used under the joint custody of Solv Protocol, iZUMi Finance, and Cobo to provide liquidity to iZiSwap. iZiSwap is the first decentralized exchange (or DEX) that adopts the discretized-liquidity AMM model, or DLAMM, which significantly enhances capital efficiency by allowing the liquidity to be deployed in every price tick and reducing slippage when swapping tokens.

Bond farming: A new paradigm of yield farming

The income generated from the liquidity provision will first be used to repay the investors of the Bond Voucher and then reward the market makers. This way, CAKE holders could earn rewards now by investing in the IZI Bond Voucher as opposed to staking a trading pair into a liquidity pool like PancakeSwap.

Using EthSign, iZUMi will sign an on-chain Issuance and Redemption statement outlining its commitment to repay the Voucher. When the Voucher matures, the borrowed funds and accrued interest will be deployed from the multisig Cobo Safe to Solv’s smart contract to pay the investors.


iZUMi will (over)collateralize the issuance with $2.13 million USD worth of iUSD tokens.

Investment risks

There are three risk factors associated with IZI Bond Voucher:

  • Volatility of IZI token.
  • Protocol security of iZUMi. The protocol’s smart contract has successfully passed the audits by Certik and BlockSec and has not suffered any security vulnerabilities or loss of users’ funds.
  • iZUMi’s creditworthiness. We have found iZUMi Finance to be creditworthy. It has made three rounds of bond issuances in the past through Solv Protocol and has repaid all its debts in a timely manner.
