Smarter than the average bear market vault. The vault that survives when others bleed.

Yogi is a production-grade USDC vault on Solana that runs dynamic tilted delta-neutral positions on Drift — buying spot and shorting perps to eliminate price risk while collecting funding. A 5-dimensional anomaly detection engine (including real-time cross-venue funding comparison against Binance and Bybit) dynamically adjusts tilt, deployment, and leverage. While BTC dropped 7.4% in one week, Yogi delivered +$8.08 (+1.61%) with zero drawdown. It's not the highest yield — it's the one that survives.

Live on Solana mainnet since March 20, 2026. $500 deposited. Zero drawdown. Keeper running 24/7 on AWS EC2.

We evaluated every major perp DEX for delta-neutral feasibility. DN requires both spot and perp markets on the same venue. Most don't qualify:

No viable EVM venue exists for delta-neutral today. Vertex was the best EVM candidate but shut down on Arbitrum. With Ethereum refocusing on L1 scaling (Vitalik's recent direction), L2 platforms face existential uncertainty — building long-term yield infrastructure on an L2 is risky.

Drift and Hyperliquid are both independent L1s — no Ethereum dependency, no L2 migration risk. This wasn't accidental. It was a deliberate platform selection.

Drift's composability — spot + perp + lending in one account, no bridges — makes it the natural platform for institutional multi-asset DN. Hyperliquid's HYPE funding is structurally positive due to ecosystem conviction, providing stable single-asset yield.

Neither platform "won." They serve different purposes and complement each other. But if institutions are choosing one foundation for yield infrastructure, Drift's composability, diversification, and independence make it the stronger long-term choice.

To understand something properly, you need to see outside of it. We built on both. PerpU — our perp DEX learning platform — shares what we learned.

During a week where BTC dropped 7.4% ($73,872 → $68,402), Yogi:

DOGE funding collapse: Drift DOGE funding spiked to -3,271% APY. Yogi's cross-venue detector showed Binance at -6.4% and Bybit at -6.9% — confirming the distortion was Drift-specific. The keeper exited the DOGE SHORT and rotated to SUI (+1,034% APY).

Cross-venue divergence: Drift BTC funding at +1,445% while Binance at -7.5% and Bybit at -9.6%. A +1,454% spread. Yogi sees this and flags convergence risk on every BTC entry decision.

Regime discipline: Vol stuck at 57-61% (high regime). Yogi automatically limited deployment to 50% at 0.5x leverage. Many vaults would be fully deployed — Yogi chose safety, and the bear market proved it right.

Zero drawdown through a -7.4% BTC week. That's the story.

Yogi's primary mode is delta-neutral: buy spot + short perps on the same asset. Price movement cancels out — profit comes purely from funding rate collection. A dynamic tilt adds slight short bias (0-10%) in calm markets for extra yield, automatically reducing to 0% (pure DN) when signals detect stress.

Unlike static delta-neutral vaults, Yogi adjusts its short bias in real time:

The tilt is computed every rebalance cycle using signal severity, vol regime, and current funding direction. This is not available on any other Drift vault.

1. Delta-Neutral on Drift — buys spot + shorts perps within Drift's own markets. Zero price risk. Most Drift vaults are directional and bleed during drawdowns.

2. Dynamic Tilt — adjustable short bias (0-10%) responds to market conditions in real time. Pure DN in stress, tilted for extra yield in calm markets. No other vault does this.

3. 5D Signal Detection — OI shifts, liquidation cascades, funding instability, spread blow-outs, AND cross-venue funding divergence. Five early warning systems, checked every 5 minutes.

4. Cross-Venue Intelligence — the only Drift vault that compares funding rates against Binance and Bybit in real time. When Drift DOGE funding is +2,000% but Binance is -6%, Yogi knows that's a distortion, not an opportunity.

5. CEX Open Interest Tracking — monitors $9.3B of BTC open interest and $1.3B of SOL open interest across Binance and Bybit. OI surges signal incoming volatility before it hits Drift.

6. Regime Discipline — vol at 57%? Yogi goes cautious (55% deployed, 0.5x leverage, 0% tilt). Not because it's told to, but because the deployment matrix says high vol + signals = protect capital.

7. Multi-Asset DN — SOL, BTC, ETH, POPCAT, and DRIFT all have spot+perp markets on Drift. Yogi can run DN on up to 3 simultaneously, dynamically selecting the highest-funding markets. Drift has 20+ DN-eligible pairs — a long tail of Solana-native assets unavailable on any other venue. Kodiak (Hyperliquid) is limited to single-asset DN on HYPE.

8. DN on DRIFT token — Yogi is the only vault running delta-neutral on Drift's own token. When DRIFT holders are long-biased, the perp short collects funding. This is only possible on Drift — no CEX or other DEX has DRIFT spot+perp.

Every other vault shows a backtest. Yogi shows live mainnet performance through a -7.4% BTC drawdown with zero loss.

Drift has 20+ additional spot+perp pairs (JUP, WIF, PYTH, TRUMP, etc.) that could be added as DN candidates. The keeper dynamically selects the highest-funding markets from the eligible list.

The regime engine is Yogi's core differentiator. It combines two inputs into a deployment decision:

Matrices are loosened vs pure directional because DN positions have partial price hedging — shorts and longs offset, so higher deployment is safer.

5th Dimension — Cross-Venue Funding:

$500 is proof-of-concept, not proof-of-scale. We know these risks exist. Here's our plan.

Bottom line: The current architecture works cleanly at $500-$50K. Between $50K-$500K, execution improvements (TWAP, limit orders, tighter tilt caps) are needed. Above $500K, infrastructure changes (multi-region keeper, capacity caps) become essential. We've designed for this progression — the risk management framework scales, the execution layer needs investment.

32-day comparative backtest (Feb 13 – Mar 16, 2026):

Note: Backtest was run with directional mode. DN mode reduces drawdown further by eliminating price risk entirely.

The emergency-decisions suite includes regression tests for two production bugs discovered on 2026-03-30:

• Drawdown close_all must close DN positions — the original code only closed directional positions, leaving DN positions stuck in an infinite emergency loop
• Orphaned spot below Drift min order size — 0.0999 SOL (below 0.1 SOL minimum) caused repeated transaction failures on startup

The keeper operates as a delegate on the vault's Drift user account. Capital flows through the Voltr adaptor (deposit/withdraw), while trading uses Drift SDK's placeSpotOrder and placePerpOrder for DN execution. All trades and PnL are on-chain and verifiable through the vault's Drift account.

Yogi is one piece of a larger build toward Syntx — a composable perp DEX on Solana. What Yogi proves (regime engine, anomaly detection, multi-asset DN) becomes Syntx's built-in vault intelligence.

29 @fabrknt/* infrastructure packages (margin, fees, privacy, security, state) + 5 Percolator matchers form Syntx's technology stack. The vaults prove the intelligence works before it ships as a platform.

Yogi pairs with Kodiak (Hyperliquid) to form a diversified DN funding portfolio. They harvest funding from uncorrelated sources:

Why they complement:

• BTC/SOL/ETH funding is cyclical — spikes in bull markets, can flip negative in bear.
• POPCAT/DRIFT funding is structurally positive — community conviction keeps holders long, similar to HYPE on Hyperliquid. When blue-chip funding dips, Solana-native assets often still pay.
• HYPE funding is structurally positive — HYPE holders are ecosystem believers who stay long. Kodiak earns steadily regardless of broader market.
• When one source dips, the other typically holds. Natural diversification without correlation engineering.

Combined portfolio estimate:

Both vaults share the same strategy brain (regime engine, signal detection, dynamic tilt) but operate on different chains, different assets, and different funding dynamics.

Built for the Ranger Build-A-Bear Hackathon (Mar 9 – Apr 6, 2026).

1. We proved Drift is for institutional yield, not just HFT — we built the same DN strategy on Drift and Hyperliquid. Drift's composability (spot + perp + lending, no bridges) makes multi-asset DN easy. This is the story the Drift ecosystem needs to attract institutional capital.

2. Delta-neutral eliminates price risk — the hackathon is called "Build-A-Bear." Yogi doesn't just survive bear markets — it's structurally immune to price direction. Spot + perp cancel out. Yield comes from funding, not price bets.

3. Dynamic tilt is novel technology — no other Drift vault adjusts its hedge ratio in real time based on signals. Pure DN in stress, tilted for extra yield when safe.

4. Multi-asset DN on Drift — SOL, BTC, ETH, POPCAT, and DRIFT simultaneously. Five DN-eligible markets from Drift's long tail of 20+ spot+perp pairs. The keeper dynamically rotates to the highest-funding markets. No other submission uses Drift's spot markets for DN.

5. DN on DRIFT token — Yogi runs delta-neutral on Drift's own token. When DRIFT holders are long-biased, the perp short collects funding (~106% APY). This is only possible on Drift and demonstrates the protocol's unique composability.

6. 5D cross-venue intelligence — comparing Drift funding against Binance and Bybit in real time. No other Drift vault does this.

7. Live mainnet performance, not backtests — deployed March 20, running continuously. On-chain verifiable.

8. Ecosystem contribution — Yogi isn't just a vault. PerpU is a learning platform that teaches why Drift is the right platform for institutional yield. Vault + education = ecosystem growth.

9. Production-ready — Voltr integration, delegate trading, position loading on restart, 30-second health monitoring, 62 unit tests with regression coverage. Ready for $500K seeding on day one.
