From Arbitrum Buildathon to London: Denaria’s Next Step

Denaria is going to London.

After joining the Arbitrum Open House Buildathon, competing with 278 projects, Denaria won 3rd place and secured its spot at the IRL Founder House in London.

This milestone marks an important step in our journey: from our first deployment on Linea, to expanding into the Arbitrum ecosystem, to deploying a Stylus-powered version of Denaria on Arbitrum testnet.

Why We Joined the Arbitrum Buildathon

Denaria is building a fully onchain perpetual DEX with a mobile first approach, powered by the dynAMM: a dynamic virtual AMM designed to make perp trading more transparent, efficient and composable.

After our first deployment on Linea, we started exploring Arbitrum as the next environment for Denaria’s evolution. The reason was simple: Arbitrum offered a strong ecosystem for DeFi builders, and Stylus opened a new path to optimize gas intensive operations like the ones of the Denaria protocol.

Every trade, every liquidation, every funding payment and every liquidity update needs to happen onchain.

This creates a clear challenge: how do you keep the protocol fully transparent and trustless without making the trading experience too expensive for users?

Stylus gave us a concrete way to test that question.

Bringing Denaria to Arbitrum Testnet

During the buildathon, the team focused on integrating Stylus into Denaria’s technical stack, starting from one of the most important parts of the protocol: the trading engine.

More specifically, we worked on moving part of the curve logic into Rust through Stylus, with the goal of reducing execution costs while preserving the architecture of Denaria’s fully onchain perpetual system.

The first results were promising:

  • 12.2% lower execution costs for long trades.

  • 13.4% lower execution costs for short trades.

This was an important validation for us.

The goal has always been to keep the core protocol onchain, transparent and verifiable. The Stylus implementation showed that we can continue in this direction while making the system more efficient for traders.

Alongside the technical work, we also deployed the Stylus-powered version of Denaria on Arbitrum testnet, allowing users to interact with the new implementation and helping us collect valuable feedback and data.

Road to London

Winning 3rd place in the Arbitrum Open House Buildathon is a strong recognition of the work the team has been doing over the past months.

It confirms that Denaria is building in the right direction: a fully onchain perpetual DEX, with a mobile-first approach, built for transparency, performance and simple access to perp markets.

But this is not the end of the journey. It is the next step. The next chapter is the IRL Founder House in London.

There, Denaria will keep building alongside other selected teams, receive direct feedback from the Arbitrum ecosystem, and further validate its go-to-market direction: bringing perp trading to mobile users through a simple, instant and accessible trading experience.

From Linea, to Arbitrum testnet, to Stylus, to London.

Denaria: trade, easily, everywhere.
