The Espresso Foundation is excite to reward the following teams who contributed meaningfully to the burgeoning Espresso ecosystem during Q4 2025 with a portion of the initial $ESP token supply. 

This represents Season 2 of the Espresso Partner Program, which is a multi-season incentive program that recognizes teams that have integrated with or contributed to the growth of the Espresso Network. Recipients were evaluated across five key criteria: depth of Espresso adoption, ecosystem impact, collaboration quality, team expertise, and integration effort.

These chains successfully integrated with the Espresso Network or its long-running testnet, Decaf, during Q4 2025:

• ApeChain - Successfully integrated with Espresso mainnet, bringing fast finality and composability benefits to their gaming and creator-focused ecosystem

• Huddle01 - Completed mainnet integration, exploring how Espresso confirmations can enhance their decentralized communication infrastructure

• Rufus - Successfully integrated with Espresso mainnet, gaining fast finality and laying the groundwork for cross-chain composability for its DogelonMars metaverse and gaming platform

These chains integrated with the Espresso Network prior to Q4 and remain a core part of the Espresso ecosystem:

• AppChain - An Arbitrum Orbit L2 focused on building innovative web3 apps, including mint.gg and EthCash

• Molten Network - A DeFi-focused Arbitrum Orbit L3 that supports a perp and spot aggregator

• RARI Chain - The first rollup to integrate with the Espresso Network to provide its NFT infrastructure with fast finality and cross-chain composability

• t3rn - Integrated on testnet and mainnet, advancing cross-chain execution capabilities with Espresso's fast finality

• NodeOps - Integrated on testnet and mainnet, enabling stakeholders in its decentralized marketplace for cloud computing to benefit from fast, secure transaction finality

• Celo - Contributed to developing Espresso’s OP Stack integration, critical technical work that benefits the broader ecosystem

• Nethermind - Made R&D contributions by setting up and running a Caffeinated Node for RARI Chain, strengthening network infrastructure

We also want to acknowledge the ongoing collaboration with Offchain Labs and Caldera, whose contributions continued to strengthen the Espresso ecosystem.

The most significant Q4 integration was ApeChain, which brought Espresso's fast finality to a vibrant ecosystem of entertainment and gaming apps, including Yuga Labs' Otherside metaverse.

ApeChain immediately demonstrated the practical impact of seamless crosschain composability enabled by Espresso's fast finality through a collaboration with RARI Chain: a bridgeless cross-chain NFT mint that let users pay with funds on RARI Chain to mint NFTs on ApeChain (and vice versa) without manually bridging assets.

The breadth of use cases continues to expand. This season, Huddle01 integrated to enhance decentralized communication infrastructure, while Rufus brought fast finality to its DogelonMars metaverse and gaming platform.

In the integration pipeline, teams like LitVM are leveraging Espresso to pioneer a new dual-settlement architecture. This growing diversity validates Espresso's role as flexible foundational infrastructure supporting specialized chains across multiple verticals.

Season 2 recognizes the rollups and research partners pushing Espresso's capabilities in production. Their work is stress-testing fast finality at scale and proving out cross-chain composability in real-world conditions.

Operating a rollup or planning to launch one? Season 3 is underway. If you value speed, customizability, and native composability through fast finality, connect with our team on X to explore building with Espresso.
