About PerpU

PerpU is designed and built by psyto @ Fabrknt — combining traditional finance expertise with on-chain vault engineering across Hyperliquid and Drift.

@ Fabrknt

With 15+ years in traditional finance — core banking, compliance, KYC/AML — I saw firsthand how legacy financial infrastructure fails billions of people. I moved into blockchain development to build the alternative. I built delta-neutral funding rate vaults on both Hyperliquid (Kodiak) and Drift (Yogi) to test a common claim: that Drift is for high-frequency trading, not yield. What I found was the opposite — multi-asset DN is easier on Drift. PerpU exists to share these insights.

Traditional Finance

15+ years in core banking systems, compliance, and KYC/AML at major financial institutions.

Blockchain Development

Full-stack development across Solana (Anchor/Rust) and EVM (Solidity). 50+ repositories.

Vault Engineering

Designed and built automated yield vaults on both Drift (Solana) and Hyperliquid.

Multilingual

Native Japanese, fluent English. Multi-language support planned.

What I Built

Kodiak

Hyperliquid

Kodiak: A delta-neutral funding rate vault on Hyperliquid with 4-dimension signal detection (OI imbalance, liquidation cascades, funding volatility, spread blow-outs), regime-adaptive risk engine, configurable tilt, and cross-venue intelligence.

Yogi

Drift (Solana)

Yogi: A delta-neutral funding rate vault on Drift (Solana) with multi-asset support, native lending via Drift Earn, and continuous funding rate capture.

PerpU

This platform

A learning platform born from building on both protocols. 20 courses, 182 lessons, 5 tracks covering Fundamentals, Hyperliquid, Drift, and developer content for both. Built to share what I learned — and what AI gets wrong.

Why Both Protocols?

Building the same strategy on two platforms reveals what each does best.

Hyperliquid: Single-asset (HYPE) DN only. Best for concentrated HYPE yield with tilt capability.

Drift: Multi-asset DN across SOL, ETH, BTC and more. Native lending, no bridge required.

Funding Rates: Hyperliquid settles hourly, Drift settles continuously — different optimization strategies.

Lending: HyperLend requires bridging from HyperEVM. Drift Earn is built in — zero friction.

Composability: Drift's cross-margin lets you combine perps + spot + lending in one account.

The same strategy, different architectures — understanding both gives you the real edge.

Why Hyperliquid and Drift?

This wasn't a random choice. I evaluated every major perp DEX for delta-neutral vault feasibility.

DN requires spot+perp on the same platform. That eliminates dYdX, Jupiter, Aevo, and Kwenta. Vertex had it but shut down — making EVM L2s risky for long-duration vault infrastructure. Only two independent L1s remain where DN actually works. They're complementary: HYPE-concentrated yield on Hyperliquid, multi-asset diversified yield on Drift.

The Insight Behind PerpU

Many people say Hyperliquid is centralized and Drift is decentralized — but that's not the point. Even AI claimed Drift is for high-frequency trading, not yield farming. I built delta-neutral vaults on both to test that claim. What I found was the opposite: multi-asset DN is easier on Drift, while HYPE-concentrated yield is better on Hyperliquid. To understand something properly, you need to see outside of it.

What's Next

More Protocols

GRVT is next — testnet vault (Polar) already built. More protocols will follow as the perp DEX landscape evolves.

Multi-Language

Japanese support is planned. The translation infrastructure is already in place — content localization is the remaining work.

More Courses

Each new protocol brings new tracks, new comparisons, and deeper understanding of what makes each architecture unique.
