Yield Basis (YB) Web3 Project Audit
Executive Summary
Yield Basis is an innovative DeFi protocol built by Curve Finance founder Michael Egorov that aims to eliminate impermanent loss (IL) for Bitcoin liquidity providers. By utilizing a novel 2x compounding leverage mechanism on Curve's BTC/crvUSD pools, it allows users to earn organic trading fees without the traditional IL drag. While the protocol boasts strong technical pedigree, substantial TVL (~$161.5M), and extensive security audits, it presents significant tokenomic risks. The team and investor allocations exceed conservative thresholds (totaling 37.1%), and the recent expiration of their 6-month vesting cliffs introduces substantial supply overhang. The overall risk profile is Medium-High, balancing strong technological fundamentals against aggressive insider token distribution and complex market-dependent yield mechanics.
1. General Description
Project Overview and Problem Solved
Yield Basis is an on-chain liquidity protocol designed to eliminate impermanent loss (IL) for liquidity providers [1] [2]. In traditional constant-product AMMs, liquidity providers suffer IL because their position value grows slower than the underlying asset's price [2]. Yield Basis solves this by pairing deposited BTC with borrowed crvUSD to maintain a constant 2x leveraged LP position [2]. This compounding leverage ensures the position tracks the price of BTC 1:1, effectively removing the IL drag while still capturing trading fees [2].
Target Audience
The primary audience consists of DeFi users, specifically holders of wrapped Bitcoin assets (WBTC, cbBTC, tBTC) and Ethereum, who want to earn organic, non-subsidized yield on their assets without the risk of impermanent loss [3] [4].
2. Team
Team Identity and Professional Presence
The most prominent figure behind Yield Basis is Michael Egorov, the founder of Curve Finance [5] [6]. His involvement lends significant credibility to the project's mathematical and technical foundations.
- LinkedIn: There is no official, verified company LinkedIn page for Yield Basis, and the broader team remains largely anonymous [7] [8].
- Socials: The project maintains an active presence on X (Twitter), Telegram, and Discord [9] [10] [11].
- Responsiveness: The team actively communicates through official channels, frequently updating the community on technical milestones like the deployment of Hybrid Vaults [12] [10].
Pros: Backed by a highly respected DeFi founder (Michael Egorov).
Cons: The rest of the core team is anonymous, and there is a lack of traditional corporate footprint (e.g., LinkedIn).
3. Concept/Documentation
Uniqueness and Competitor Analysis
Unlike traditional AMMs (Uniswap, standard Curve pools) where IL is a fundamental trade-off, or protocols that merely subsidize IL with inflationary token rewards, Yield Basis structurally eliminates IL through automated debt management and 2x leverage [5] [2]. Its main competitors are standard DEXs and lending protocols (like Aave) where users park BTC for yield.
Demand and Roadmap
There is clear demand for the product, evidenced by its ~$161.57M Total Value Locked (TVL) [13]. The roadmap outlined in their MiCA whitepaper included Q4 2025 integrations with leading DeFi platforms like Pendle, Aave, and Ether.fi [14]. Recently, the protocol has been rolling out "Hybrid Vaults" for WETH, indicating active development [12].
Technical Details and Revenue
- Smart Contracts: The architecture is modular, consisting of a central
Factory.vy(Market Registry),LT.vy(Market-Specific Vaults), andAMM.vy(Constant Leverage Maintenance) [4]. - Revenue Source: The protocol generates revenue from trading fees in the underlying Curve pools. 50% of fees go to pool rebalancing, and the remaining 50% (minus volatility decay costs) is split between unstaked ybBTC holders and veYB governance token holders via a dynamic admin fee [15].
4. Coin/Tokenomics
Token Distribution and Vesting
The YB token has a total supply of 1,000,000,000 (1 Billion) [16]. The tokenomics structure presents several red flags against conservative audit criteria.
| Category | Allocation | Percentage | Vesting Schedule |
|---|---|---|---|
| Liquidity Incentives | 300,000,000 YB | 30% | Dynamic emission based on staking rate [16] |
| Team | 250,000,000 YB | 25% | 2 years vesting, 6-month cliff (started Sep 15, 2025) [16] |
| Ecosystem Reserve | 125,000,000 YB | 12.5% | 50M at TGE, 2 years linear vesting for remainder [16] |
| Investors | 121,000,000 YB | 12.1% | 2 years vesting, 6-month cliff (started Sep 15, 2025) [16] |
| Protocol Dev Reserve | 74,000,000 YB | 7.4% | 1-year cliff, 1 year linear vesting [16] |
Takeaway: Both the Team (25%) and Investor (12.1%) allocations exceed the recommended 10% maximums. Furthermore, the 6-month cliff expired in mid-March 2026, meaning linear unlocks of approximately 1.5% per month for these two groups are currently active, exceeding the safe ≤0.8%/month threshold [16].
Market Metrics (as of April 2026)
- TVL: $161.57m [13]
- Market Cap: $10.21m [13]
- FDV: $84.54m [13]
- 24h Volume: $10.38m (heavily skewed to CEXs at $9.18m) [13]
5. Code
Open Source and Audits
The project maintains an open-source presence on GitHub, with repositories like yb-core showing active development [17]. Yield Basis has undergone extensive security auditing by top-tier firms.
| Auditor | Scope | Date |
|---|---|---|
| Statemind | Core Architecture | Feb 24 - May 22, 2025 [18] |
| Quantstamp | Core Architecture | Apr 1 - Apr 16, 2025 [18] |
| Chainsecurity | Core & Hybrid Vaults | Jul 2025 & Mar 26, 2026 [18] |
| Mixbytes | Core & Hybrid Vaults | Aug 2025 & Mar 26, 2026 [18] |
Takeaway: The protocol is heavily audited, including recent audits for their new Hybrid Vaults [18]. However, no formal bug bounty program (e.g., Immunefi) is explicitly linked in the documentation, though a security contact email is provided [18].
6. Risks
- Financial/Tokenomic Risks (High): The combined Team and Investor allocation is 37.1% [16]. With the 6-month cliff recently expiring, the market faces significant monthly unlock pressure.
- Market/Yield Risks (Medium): The protocol features a "High Watermark" recovery mode. If volatility decay causes the LP share price to drop below its all-time high, 100% of revenue is diverted to restore LP value, meaning veYB holders receive zero admin fees during this period [15].
- Technical Risks (Medium): While heavily audited, the protocol relies on complex compounding leverage and external dependencies (Curve, crvUSD). The recent introduction of Hybrid Vaults introduces new smart contract surface area [12] [18].
- Team Risks (Medium): Aside from Michael Egorov, the team operates anonymously, which is common in DeFi but presents accountability risks [7] [10].
7. Community
The project has cultivated a healthy, organic community focused on DeFi mechanics.
| Platform | Size | Activity Notes |
|---|---|---|
| X (Twitter) | ~34.8K Followers | Active posting, technical updates, founder retweets [10] |
| Discord | ~4,098 Members | ~380 online, active technical discussions [11] |
| Telegram | ~2,524 Members | Active community chat, scam warnings pinned [9] |
8. Final Assessment
- Risk Level: Medium / High
- Key Strengths:
- Genuine technological innovation solving a core DeFi problem (Impermanent Loss) [2].
- Strong pedigree via Curve founder Michael Egorov [6].
- Extensive, multi-firm audit history covering both core and new contracts [18].
- Proven product-market fit with over $160M in TVL [13].
- Key Issues and Warnings:
- Tokenomics Warning: Team (25%) and Investor (12.1%) allocations are highly centralized [16].
- Unlock Overhang: The 6-month cliff ended in March 2026, initiating aggressive linear vesting that exceeds conservative monthly limits [16].
- Yield Volatility: Protocol revenue to token holders can drop to zero during "Recovery Mode" drawdowns [15].
- Liquidity: Secondary market trading is heavily reliant on centralized exchanges rather than on-chain DEX liquidity [13].
