The decentralized finance (DeFi) wave continues to sweep across blockchain ecosystems, and EOS is no exception. After months of relative dormancy, the EOS network is showing renewed signs of life—thanks to a new DeFi project called DeFis, often dubbed the "Uniswap + Compound + Maker of EOS." With transaction mining, liquidity incentives, and a multi-functional platform in development, DeFis is re-energizing the EOS community and drawing attention from both users and investors.
This article dives deep into what DeFis is, how it works, and why it might be more than just another short-lived yield farming trend. We’ll explore its core features, economic model, and potential impact on the broader EOS ecosystem—all while keeping SEO and reader engagement in mind.
What Is DeFis?
DeFis—short for "Decentralized Finance System," and affectionately known as "Big Harvest" in Chinese communities—is a native DeFi protocol built on the EOS blockchain. Positioned as an all-in-one DeFi solution, DeFis integrates functionalities inspired by leading Ethereum protocols such as Uniswap (decentralized exchange), Compound (lending), Synthetix (synthetic assets), and MakerDAO (stablecoin issuance).
Currently live are two primary modules: SWAP and BANK. Upcoming features include LEND (lending) and SYNTHETIX (asset synthesis), promising a comprehensive suite of financial tools for EOS users.
Two native tokens power the ecosystem:
- USDD: A stablecoin pegged to the US dollar, minted by locking EOS as collateral.
- DFS: The platform’s governance and utility token, distributed via transaction mining.
How Does DeFis Work?
DeFis operates through three main mechanisms: collateralized minting, transaction mining, and liquidity provision (market making). Let’s break each down.
1. Collateralized Minting of USDD
Users can generate USDD by depositing EOS into the DeFis smart contract. While early analyses suggested a target collateral ratio of 3:1 for risk mitigation, current on-chain data shows effective ratios closer to 1.1:1—indicating high leverage and potential volatility risks.
Despite this, the ease of generating a stablecoin directly on EOS has attracted early adopters looking to leverage their holdings without selling.
2. Transaction Mining for DFS Rewards
Unlike EIDOS’ “transfer-to-mine” model that flooded the network with spam transactions, DeFis uses transaction mining—rewarding users who actively trade on its SWAP platform.
Key details:
- DFS total supply: 1 billion
- Distribution period: 3 years
Emission rate: 10 DFS per second
- 8 DFS go to the mining reward pool
- 2 DFS allocated to the team (non-transferable, voting-only)
To qualify for rewards, trades must be at least 1 EOS in value. Larger trades receive higher weightings:
- EOS/USDD pair: weight = 1
- Other pairs: weight = 0.3
Weight adjustments will be decided via community governance votes.
In essence, every trade incurs a 0.3% fee—but users see this not as a cost, but as an investment in earning DFS tokens.
3. Liquidity Provision and Fee Sharing
Every 0.3% transaction fee is split:
- 0.2% goes to liquidity providers (LPs), distributed proportionally based on their share in the pool.
0.1% is protocol fee:
- 50% to the team (early-stage funding)
- 50% to a staking reward pool for DFS holders
Staking DFS allows users to earn passive income from protocol fees. Rewards are claimable every 24 hours, either manually or via third-party automation tools. Unstaked DFS takes three days to unlock, during which no rewards accrue.
Future upgrades aim to enhance capital efficiency and reduce impermanent loss risks for LPs.
Why Is DeFis Gaining Traction?
Several factors contribute to DeFis’ rapid rise:
Surging Resource Demand on EOS
Recent spikes in REX (Resource Exchange) utilization—from ~45% to over 73.6%—signal increased network activity. A single account reportedly leased around 20 million EOS via REX, pushing borrowing rates up to 4% annual yield. While not officially confirmed, evidence points to DeFis-related operations driving this surge.
This level of resource demand hasn’t been seen since the EIDOS airdrop craze six months ago.
Strong Community and Ecosystem Support
DeFis enjoys backing from major players:
- Supported by Newdex DeFi Fund and Hoo Fund
- Integrated into wallets like MYKEY, MEETONE, and TP
- Listed on exchanges including Hoo.com, WhaleEx, and Newdex
Even prominent figures like Wang Ruixi, founder of Hoo Wallet and a well-known EOS RAM holder, have participated by minting USDD with 10,000 EOS.
He noted that DeFis effectively aligns incentives between users, liquidity providers, and token holders—a key differentiator from previous EOS dApps.
Future Roadmap: Lending and Synthetic Assets
Beyond trading and stablecoins, DeFis plans to expand into advanced DeFi functionalities.
DeFis Lend – Overcollateralized Lending Platform
Users will be able to:
- Deposit digital assets to earn interest
- Borrow against collateralized positions
This mirrors models seen on Compound or Aave but adapted for EOS’ fee-less transaction environment.
DeFis Synthetix – On-Chain Derivatives Marketplace
By staking DFS, users could mint synthetic versions of real-world assets—such as stocks, commodities, or indices—enabling:
- Long/short exposure without counterparty risk
- Near-infinite liquidity due to algorithmic settlement
- Privacy-preserving trading of off-chain assets on-chain
If successfully implemented, this would position DeFis as one of the most ambitious DeFi projects on EOS.
Is DeFis Worth Participating In?
While enthusiasm runs high, due diligence is essential.
Positive Indicators
- Rapid user growth: Over 208 unique users in 7 days (per DappRadar)
- Transaction volume up by 2,668%
- Smart contract audit reports published in collaboration with SlowMist
- Active development updates and transparent communication
Risks to Consider
- Low current collateral ratio for USDD raises solvency concerns
- High emission rates could lead to downward price pressure on DFS
- Dependence on sustained trading volume to maintain miner interest
EOS42’s Jing Kai highlighted that the team previously participated in a BlockOne hackathon under the name JIN Network—with a prototype already showcasing core functionalities. This suggests technical credibility and continuity in development.

Frequently Asked Questions (FAQ)
Q: What makes DeFis different from EIDOS?
A: EIDOS used a “free transfer” model that generated spam transactions. DeFis requires meaningful economic activity—specifically trading—to earn rewards, making it more sustainable and aligned with real DeFi principles.
Q: Can I stake DFS for passive income?
A: Yes. By staking DFS, you earn a share of the 0.05% protocol fee collected from trades. Rewards are distributed daily.
Q: Is USDD truly stable?
A: USDD aims to maintain a $1 peg through overcollateralization. However, with current collateral ratios near 1.1x, there's limited buffer against EOS price drops. Close monitoring is advised.
Q: Who controls the DFS token distribution?
A: The majority of DFS tokens are released through transaction mining. Only 20% go to the team (locked for long-term use), ensuring broad decentralization.
Q: Are there security audits available?
A: Yes. Initial audit results have been published with SlowMist, with additional reviews planned with other security firms.
Q: How do I start using DeFis?
A: Access DeFis through supported wallets like MYKEY or TP. Connect your EOS account, swap tokens on SWAP, or mint USDD via the BANK module to begin earning.
Final Thoughts
DeFis represents a pivotal moment for EOS in the age of DeFi. By combining yield generation, decentralized exchange functionality, and future lending/synthetics capabilities, it offers one of the most complete DeFi experiences on the network so far.
While challenges remain—particularly around stability mechanisms and long-term tokenomics—the momentum is undeniable. As more users join and liquidity grows, DeFis could become the cornerstone of a revitalized EOS ecosystem.
