Let’s take a look at the key details and highlights of Watermelon below so that you better understand what Watermelon offers and able to make a more informed investment decision.
What is Watermelon? 🍉 🍉 🍉
The mission of Watermelon (Xigua) is to be the Uniswap + MakerDAO of the IOST blockchain and provide decentralized trading and stable coin lending services. Xigua adopts a dual token system in which:
- XG is the platform token with a total supply of 4,000,000 tokens, from which 90% will be available for farming (mining)
- XUSD is a stable coin, which is generated through the collateralization of IOST on a 2.5 IOST : 1 XUSD ratio.
Watermelon is currently under final public testing and will be launched soon.
Watermelon Contract- Review and audit from the IOST technical team
In the spirit of protecting and being responsible to investors, the IOST technical team conducted a preliminary internal audit on this project, and the conclusion is that the code is mature and stable, and there are no risks related to the smart-contract code. The Watermelon team is working with a well-known third-party professional team for the second round of audit.
In addition, Watermelon has been under public testing for a week, and thanks to the help of community members, many bugs have already been fixed.
Why Watermelon? Key Highlights & Benefits
1) Silky smooth experience & Zero transaction fees
High transaction fees and low speed are now the most known characteristics of Uniswap. Gas wars and losses due to the slow transaction speed happen on a daily basis. Thanks to the lightning-fast speed of the IOST blockchain that powers Watermelon, users don’t need to pay transaction fees.
The second half of the DeFi match has just begun. We believe that in the next 6 months, more DeFi projects will emerge on the IOST mainnet bringing more high-quality off-chain assets.
2) Interest-free minting of stable coins
On Watermelon, thanks to the rewards given to partner nodes on the IOST mainnet, minting is free and interest-free.
After you pay off the loan, you can choose to wait for the 3 days freezing period to get back the staked IOST for free or to withdraw immediately for a small fee (about 0.5%).
3) Wealth management with stable coins
Watermelon has a unique economic model in which the IOST collateralized for minting will be transferred to the Liebi Pool to generate incomes. Then, 90% of these incomes will be given back to users who stake stablecoins as interests.
In addition, while staking XUSD, users are also participating in liquidity mining and can earn platform tokens XG.
4) Liquidity Mining
Liquidity mining pools available now:
XUSD Pool, with an allocation of 1 point
- Coin Voyage Diamond ZS token / XUSD Pool, with an allocation of 1 point. ZD is the token used in the popular IOST blockchain game Coin Voyage
- TPT / XUSD Pool, with an allocation of 2 points. TPT is the token used in the popular wallet app TokenPocket

- XG / XUSD Pool, with an allocation of 25 points. Xigua’s platform token. It will be launched 3 days later than the rest of the pools to help investors reduce the risks
5) Repurchase and Burning of XG
Revenue of the platform comes from listing fees, transaction fees, dividends from Liebi, and so on. All the revenue mentioned above will be used to buy back and burn XG.
6) Potential cooperation with major exchanges
According to the Watermelon team, major exchanges considering to add financial products to their catalogs will give priority to cooperation with Watermelon Finance. However, the IOST foundation cannot confirm this news on behalf of Watermelon. We will keep our community up to date as always.

IOST- A Home to Build Your Ideal DeFi dApps!
Decentralized finance, or in short DeFi, is a notion that the traditional financial system can be replicated on a decentralized, open-source, resilient environment, seamlessly operating without a middle man. Compared with other projects, DeFi has a lower threshold, relatively transparent investment environment, and considerable interest rates, which drive its rising popularity in the crypto market.
For DeFi dApps to satisfactorily compete with traditional applications, the underlying network must be fast, meeting the objectives and expectations of the dApp developers. In the mid of competition, IOST — an enterprise-grade, decentralized, and ultra-fast network oiled with the Proof-of Believability (PoB) consensus algorithm has what it takes to build a vibrant ecosystem by offering developer-friendly features and environments.
As one of the world’s leading public blockchain platform, IOST’s original PoB consensus mechanism can ensure better scalability and faster speed on the basis of decentralization. At present, IOST mainnet has shown a peak TPS of up to 8000. IOST offers developer-friendly features that improve product development efficiency. No congestion and no high gas fees as seen in Ethereum, the reason many developers choose to launch DeFi projects on IOST. A zero transaction fee also guarantees users the convenience and accessibility of using DeFi applications on the IOST chain.
By inking symbiotic deals with strategic partners and promising on-chain projects such as PowerDeFi, otbTRADE, ProDeFi from all over the world, IOST will gradually cement its position, even supplement activities of competing platforms for the better good of the space.
With the establishment of the Noah Oracle One-Million Dollar Fund and the additional Six-Million DeFi Fund, IOST gears up to unlock the potentials of more DeFi projects on its vibrant network.
