Marcin Kaźmierczak is the co-founder, and COO of RedStone Oracles, the modular and fastest-growing blockchain oracle. He is also co-founder of the largest Web3 tech conference in Central and Eastern European (CEE) region - ETHWarsaw ^[1]. Speaker at global crypto events like Consensus, Token2049, DevCon, Avalanche Summit. Forbes 30 under 30 Poland laureate ^[2].

" 2017 - I learned about Bitcoin and Ethereum from my older brother while doing my quantitative methods undergrad. He shared a few articles, so I started learning about the technology and became fascinated."

Education

Marcin graduated from the Warsaw School of Economics in 2020 with an e-business speciality and then did an MBA course at 國立政治大學 University in Taipei (NCCU). His thesis was around "Blockchain technology - thorough description and business use cases"

Early Career

2017 marked Marcin's entry into crypto while pursuing quantitative economics. His passion led him to the Polish Accelerator of Blockchain Technology in 2018, where he helped Polish institutions navigate Bitcoin transaction tracking.

That same year, fate connected Marcin with Jakub Wojciechowski - RedStone's future Founder & CEO. Jakub, a seasoned engineer with 23 years of experience, would later revolutionize leveraged synergic trades, claiming victory at the 2020 New York City Blockchain Week Hackathon.

While Marcin's path led through Taipei and Google Cloud, Jakub was uncovering critical limitations in existing oracle solutions like Chainlink. 2021 brought their paths together again when Jakub and Marcin co-founded RedStone - a decision that would reshape oracle infrastructure.

Marcin and Jakub got traction pretty quickly, raising a $525k pre-seed round in April 2021 and after the first product validation in March 2022 raising a seed round of $7 Million led by Lemniscap with participation from Blockchain Capital, Coinbase Ventures, Maven11 and other top funds. In June 2024, they announced their $15 Million Series A led by Arrington Capital. During these 36 months, they managed to gain prominent angels: Stani from Aave, Sandeep from Polygon, Emin from Avalanche and more.

Business Approach 

At ETHwarsaw 2024 Marcin gave a speech with practical tips for potential founders.

The top 10 advices were :

1. Study DeFi - Before diving into day-to-day tasks, invest time in understanding DeFi fundamentals. Grasp how money flows, what the key primitives are, and how they interconnect.

2. Master Seed Phrases and Wallets - Know how to manage seed phrases securely. Learn the differences between hot wallets (e.g., MetaMask) and cold wallets (e.g., Ledger). Understand that MetaMask is convenient but not necessarily best for long-term asset storage

3. Understand Ethereum Deeply - Even though there are many chains (Solana, Avalanche, etc.), Ethereum remains the most mature ecosystem. Learn how smart contracts work, including the EVM (Ethereum Virtual Machine) and how blocks are produced.

4. Explore Layer 1s and Layer 2s - Familiarize yourself with the differences between optimistic rollups, ZK-rollups, and rollups-as-a-service. Understand what a “sequencer” is and how it operates in L2 networks.

5. Study Stablecoins and Their Histories - Learn why certain stablecoins (e.g., Tether/USDT) dominate centralized exchanges while others (e.g., USDC from Circle) play a bigger role on DEXs. Dig into the backstory of each major stablecoin to understand liquidity and trust factors.

6. Learn DEX Mechanics - DEXs (Decentralized Exchanges) are a core DeFi primitive. Understand slippage, impermanent loss, and liquidity provisioning (LP). Practice small trades or use testnets to experience the pitfalls (like high slippage) before risking large amounts.

7. Master Lending Protocols and Risk - Lending and borrowing form another DeFi backbone. Learn about collateral requirements, liquidation thresholds, and how liquidation actually happens. Experiment with small positions to see how the process works in practice.

8. Dive into Staking - Liquid Staking is poised to be one of the most important crypto primitives. Unlike traditional finance, where owning a stock does not automatically yield more of that stock, in crypto you can earn additional tokens by staking. Understand the long-term implications for protocol security and yield generation.

9. Distinguish Bridges from Oracles - Bridges facilitate asset transfers between chains. Oracles deliver data to on-chain environments. Explore multiple solutions (LayerZero, Wormhole, Chainlink, RedStone, etc.) to see how each approaches trust and security.

10. Understand the difference between Mcap and FDV -  Simple, but many don't know.

Presentations & Interviews

Consensus Push vs Pull Oracle breakdown by Marcin

Marcin discusses the critical role of oracles in DeFi and introduces RedStone’s unique push and pull oracle models, highlighting how RedStone focuses on real-time, efficient price feeds (especially for LSTs). They emphasize their nimbleness in supporting new protocols and networks quickly, differentiating themselves from incumbents like Chainlink and Pyth. The conversation touches on Oracle Extractable Value (OEV) and how future innovations, including restaking, might reshape the economic incentives around liquidations and security. Finally, they outline RedStone’s expansion plans, including deeper involvement in L2 ecosystems, potential token launches, and further partnerships with emerging DeFi projects. ^[4]

RedStone: The Oracle Pioneering the Future of DeFi 

The DeFi landscape has significantly evolved since 2018 when Chainlink was launched. Recent developments such as L2 rollups, liquid staking, restaking and the rise of BTC DeFi have created huge demand for more customizable, modular oracles that would be able to provide accurate data for countless use cases, crosschain. RedStone set out to do exactly that and are now securing over $6.6 bn worth of assets (1000+ assets), across more than 60 chains, without a single mispricing event.

Marcin, Co-Founder of RedStone Oracles, discusses the trade-offs between using a “market rate” (DEX-based) versus a “contract (exchange) rate” (fundamental value) for pricing yield-bearing tokens like LSTs and liquid staking assets. He explains how a purely market-based oracle feed can reflect real-time supply and demand but may cause unnecessary liquidations during short-term price deviations or flash crashes. Conversely, a purely contract-based rate can mask sudden protocol failures since it doesn’t account for real-world market activity. He proposes a hybrid model that combines snapshots of contract-based fundamentals with market-rate data (and potentially time-weighted averages) to better handle volatility and improve security for lending protocols.
