Hedging Against High Ethereum Gas Prices with On-Chain Derivatives
The Ethereum blockchain has emerged as the second most popular decentralized network after Bitcoin. Its implementation of smart contracts pioneered decentralized applications, and it became a cradle of Decentralized Finance (DeFi) amongst other fields. Despite substantial technological advancements aimed at optimizing transactional costs to withstand its growing adoption, including Layer-2 scaling solutions and protocol upgrades such as EIP-1559 and EIP-4844, the gas price remains volatile and unpredictable. This research presents a novel decentralized application enabling the issuance of a gas price derivative in the form of option contracts designed to hedge against high gas prices. We thoroughly analyze the mechanics of Ethereum's gas and the underlying economic process governing the price of gas. We design and implement a decentralized application that enables permissionless creation of such option contracts. These contracts allow users to purchase options on-demand and exercise them at a predefined block height for gas fee management.

Protocol for unifying cross-chain liquidity on polkadot
Liquidity is critical for a healthy and thriving blockchain ecosystem, enabling value exchange between participants. However, achieving unified liquidity across heterogeneous blockchain platforms remains challenging due to disparities in architecture, virtual machines, and asset management logic. These disparities force assets to be wrapped into other formats to ensure compatibility with underlying systems, thus fragmenting liquidity into multiple pools. This paper proposes LiquiSpell, a novel protocol that aims to unify liquidity across multiple parachains within the Polkadot ecosystem. By leveraging the cross-chain message passing (XCMP), LiquiSpell introduces the concept of a universal transaction that can be constructed to be compatible with any parachain, regardless of its underlying architecture or asset management pallet. This approach overcomes the obstacles posed by the diverse nature of parachains, enabling seamless asset sharing and enhancing cross-chain interoperability. The proposed solution mitigates liquidity fragmentation within the Polkadot ecosystem. It presents a framework that can be extended to other multichain environments outside Polkadot. Ultimately, LiquiSpell aims to foster a thriving ecosystem by facilitating the introduction of new assets and increasing overall liquidity, thereby driving innovation and adoption within the DeFi landscape.

Frequently Asked Questions
Quick answers about working with Decenzio.
What does Decenzio do?
Decenzio is a Web3 development house that designs, builds, and scales blockchain products end to end: smart contracts, full-stack dApps, Web3 frontends, and the infrastructure behind them. We also provide consulting, tokenomics design, technology assessments, developer training, and on-chain research and analytics. Less hype, more build.
Which blockchains does Decenzio support?
We build on Ethereum and its L2s, EVM-compatible L1s, Polkadot, Solana, Cosmos, Stellar, Bitcoin, VeChain, and Algorand. Core languages are Solidity, Rust, TypeScript, Python, and Go, with frameworks like Foundry, Hardhat, OpenZeppelin, Next.js, and Nuxt. If your chain is not listed, ask — the stack keeps growing.
Does Decenzio build and secure smart contracts?
Yes. Smart contract development is our core service: battle-tested contracts for DeFi, NFTs, DAOs, and custom protocols, written in Solidity or Rust with audit-driven best practices, gas optimization, and upgradeability patterns. Security reviews and thorough testing are part of every delivery, not an optional extra.
How does a project with Decenzio start?
Every engagement follows four steps: Discovery (understanding your vision, requirements, and constraints), Design (architecture, wireframes, and technical specifications), Development (agile delivery with regular updates and milestone reviews), and Launch (testing, deployment, and ongoing support). To begin, email hello@decenzio.com — we respond within 24 hours.
How much does Web3 development cost?
Cost depends on scope: a standalone smart contract is a much smaller engagement than a full dApp with frontend, indexing, and infrastructure. After a discovery call we scope the work and quote it with milestone-based pricing, so you know the price before development starts. Email hello@decenzio.com for an estimate.
Where is Decenzio based?
Decenzio is based in Bratislava, Slovakia, operating on Central European Time and working with clients globally. The company was founded in 2024 by execution-driven builders active across the Web3 ecosystem, including research and open-source work published on GitHub.
