YFII: The Revolutionary DeFi Fork That Defied the Odds

·

In the fast-evolving world of decentralized finance (DeFi), few projects have sparked as much controversy, innovation, and community-driven momentum as YFII. Born from a contentious fork of the pioneering yield aggregator YFI, YFII emerged not just as a technical clone—but as a powerful statement of decentralization, fair distribution, and community sovereignty.

This is the story of how a grassroots movement, primarily led by Chinese DeFi enthusiasts, challenged the status quo of Western-dominated DeFi projects—and succeeded where nearly all other forks failed.

The Birth of YFII: A Response to Governance Failure

The origins of YFII trace back to YIP-8, a governance proposal within the YFI community aimed at increasing token supply to ensure broader distribution and sustained liquidity mining incentives. Despite receiving over 80% approval, the proposal failed due to low voter turnout—only 9.73% of total holders participated, falling short of the required 33% threshold.

This governance deadlock exposed a critical flaw: early whales controlled most of the voting power, leaving latecomers—especially those from non-Western communities—with little influence. For many Chinese DeFi users, this wasn’t just unfair—it was exclusionary.

In response, a faction of the community decided to take matters into their own hands. On July 27, 2020, just one day after YFI halted mining, YFII (Yearn Finance II) was launched as a community-driven fork. Unlike its predecessor, YFII implemented a Bitcoin-style halving mechanism:

This design ensured that anyone contributing liquidity could earn tokens fairly—without pre-mines, team allocations, or VC backing.

Why YFII Succeeded Where Others Failed

While thousands of DeFi clones and forks have come and gone, YFII stands out as one of the rare successful forks in crypto history. Most forks collapse due to lack of innovation, weak communities, or outright scams. But YFII did something different.

1. Fair Launch & Anti-Whale Mechanics

By adopting a halving model similar to Bitcoin, YFII discouraged large players from dominating early rewards. Smaller participants had a real chance to accumulate tokens through consistent participation.

2. Strong Community Governance

Within days, YFII established a decentralized governance structure with 11 key holders managing multisig wallets. This wasn’t a top-down project—it was built by contributors for contributors.

3. Real Utility and Innovation

YFII didn’t just copy YFI—it evolved it. The team introduced new features like:

At its peak, YFII’s total value locked (TVL) approached $100 million**, with token prices reaching an all-time high of **$1,128—a staggering return for early liquidity providers.

4. Global Ambition with Local Roots

Though initially driven by Chinese DeFi users—affectionately calling YFI “Big Auntie” and YFII “Second Auntie”—the project quickly attracted international developers and investors. It avoided nationalist isolation and instead embraced global collaboration.

“YFII wasn’t just a fork—it was a revolution. It proved that a decentralized community could build something better, faster, and fairer.” – DeFi Analyst

From Rivalry to Coexistence: YFI vs. YFII

Initially, tensions were high. Andre Cronje, founder of YFI, expressed skepticism about YFII’s long-term viability, suggesting that TVL would eventually flow back to Yearn.finance. Some Western platforms like Balancer even labeled YFII as a “scam,” citing risks from copycat projects like YFIII and YYFI—many of which were indeed exit scams with single addresses holding over 90% of supply.

But YFII proved different.

Over time, communication improved. Cronje began sharing memes about YFII and even proposed extending Yearn’s revenue-sharing model to include YFII holders. While the two projects remain independent, they’ve entered a phase of co-opetition—competing on metrics like TVL and user growth while collaborating on ecosystem development.

Frequently Asked Questions (FAQ)

Q: Is YFII still active today?
A: Yes. While its prominence has decreased compared to 2020’s peak, YFII continues to maintain an active development roadmap and community presence.

Q: How does YFII differ from YFI technically?
A: YFII uses a halving-based emission schedule instead of fixed weekly emissions. It also introduced enhanced auto-compounding mechanisms and faster iteration cycles.

Q: Was YFII a scam?
A: No. Unlike many other YFI forks (e.g., YFIII), YFII delivered real code updates, transparent governance, and long-term utility—proving it was not an exit scam.

Q: Can I still mine or stake YFII?
A: Mining concluded within the first 10 weeks after launch. However, staking options may exist on third-party platforms depending on current protocol updates.

Q: Why did other YFI forks fail?
A: Most were launched purely for profit—with no real product, team accountability, or community input. They lacked the grassroots legitimacy that defined YFII.

Q: Does YFII have plans for cross-chain expansion?
A: Yes. There have been discussions and preliminary efforts to deploy YFII on chains beyond Ethereum, including BSC and Polygon, to reduce gas costs and increase accessibility.

Final Thoughts: A Milestone in Decentralized Autonomy

YFII represents more than just a successful fork—it’s a case study in decentralized resilience. It showed that when a community feels excluded, it doesn’t have to accept the status quo. Instead, it can build an alternative that’s more equitable, transparent, and sustainable.

While the initial wave of "YFX" clones faded into obscurity, YFII endured—not because of hype, but because of purpose.

As DeFi matures, the lessons from YFII will remain relevant: true decentralization means giving power to the people, not just in theory—but in practice.
