K3 Capital

K3 Capital is an institutional-grade asset manager that has been deploying non-directional DeFi strategies since 2021, serving crypto-native institutions and high-net-worth investors. It operates three structured funds — Absolute USD Return Fund, Enhanced ETH Fund, and BTC Yield Fund — plus Segregated Managed Accounts, focusing on liquidity provisioning, interest-rate arbitrage, and early-stage protocol participation across multiple blockchain networks.

K3 Capital makes money for its investors through several on-chain strategies that don't bet on prices going up or down ("non-directional"). Exactly which strategies are used depends on the fund. Here is a breakdown by fund:

Absolute USD Return Fund

The fund does a mix of things:

• Supplies liquidity (lends assets) to carefully chosen lending platforms and decentralized exchanges
• Trades in fixed-yield markets (where returns are predictable)
• Helps launch new stablecoins that are backed by real-world currency
• Captures "basis trades" using decentralized perpetual exchanges (like dYdX and Hyperliquid) — these trades profit from price differences between spot and futures markets
• Joins newer DeFi experiments, such as tokenized cash-and-carry strategies (Ethena) and stablecoin-based liquid restaking tokens. For these, K3 also acts as an AVS curator (a role that helps choose and oversee services that secure other networks)

What generates the yield: fees paid by protocols to liquidity providers, plus extra token rewards from the protocol, the issuer, or the network where the liquidity sits, plus funding rates from perpetual positions when applicable.

Enhanced ETH Fund

This fund aims to earn more than standard ETH staking rewards by:

• Using recursive non-directional leverage (borrowing against the same asset repeatedly in a careful loop to amplify returns without directional bets)
• Interest rate arbitrage across non-ETH assets (borrowing where rates are low, lending where rates are high)
• Supplying liquidity to decentralized exchanges
• Engaging with staking and restaking protocols

Yield comes from protocol fees shared with liquidity providers, plus token incentives from issuers and networks.

BTC Yield Fund

This fund bridges native Bitcoin to smart-contract networks (like Ethereum) so it can be used for lending, borrowing, and non-directional liquidity provision. Tokenized versions of BTC serve as collateral to borrow productive assets, which then get deployed in strategies similar to the Absolute USD Return and Enhanced ETH Funds. BTC is also used in newer designs like Bitcoin-focused Layer 2s and liquid restaking tokens.

Across all strategies, K3 Capital does its own research before committing funds: it reviews smart contract audits, checks economic and operational security risks, and assesses whether each yield source is sustainable. It negotiates terms with protocol teams and rebalances the portfolio under a risk framework that sets limits at both the protocol and network level.

The firm also builds its own DeFi tools — including sBOLD (a yield-bearing stablecoin that collects rewards from Liquity v2 Stability Pools), Gearbox credit accounts for delta-neutral yield, rsUSDe (a liquid restaking token backed by stablecoin collateral), and Euler-based lending markets on Avalanche, BNB Chain, and Bitcoin. These in-house products feed directly into fund strategies and produce extra fee and emission income.

No information about investors, backers, funding rounds, or investment amounts was found on the official K3 Capital website (k3.capital) or its Substack blog. The site lists Kiril Nikolov as Co-founder and Simeon Rusanov, CFA as Chief Investment Officer (previously DeFi Lead and Head of Research at Nexo.com), and displays numerous protocol partners (Liquity, Euler, Gearbox, Ethena, Nexo, Symbiotic, Kelp, Ether.fi, Mellow, Almanak, Hypernative, etc.) — but these are integration/protocol partners, not financial backers of K3 Capital itself. No venture capital investors, institutional backers, or funding rounds are disclosed on any page reviewed.
