TriggerX is a decentralized automation protocol that enables smart contracts to execute tasks based on time, conditions, or external events in a fully automated and trustless manner. Built on EigenLayer’s Actively Validated Services (AVS), it provides shared security and decentralization to ensure reliable task execution across multiple blockchains.
BPay is a decentralized protocol for bulk business payments, invoicing, and split-bill management—secure, instant, and multi-chain.
All in one solution for your contract generation , testing , documenting and onchain reports generation
We turn staking from speculation into impact. Users stake on real farms, powered by DePIN devices and AI-driven yield data. Built on Arbitrum for faster, cheaper, scalable impact.

Stogram is a Social x Predictions platform that blends content creation, prediction markets, and staking into a single, creator-driven ecosystem that aims to prioritize user privacy and monetizing engagement.
Metanexus is an all-in-one gaming hub that merges Web2 and Web3 gaming into a single ecosystem. Unlike fragmented platforms where gamers jump between Steam for games, Discord for chat, OpenSea for NFTs, and separate esports sites for tournaments, Metanexus brings everything together in one place.
zkArb SDK is a developer toolkit that makes building zero-knowledge apps on Arbitrum simple and fast. It provides plug-and-play Circom circuit compilation, proof generation, and ready-to-deploy verifier contracts, so developers can focus on dApps instead of cryptography.
Plexi is a composable ERC-4626 vault on Arbitrum that lets users deposit USDC and automatically gain exposure to yield strategies with real-time transparency. Instead of leaving capital idle or manually chasing yields, Plexi aggregates deposits, allocates them into a strategy, tracks TVL, shares, and hedge ratios on-chain, and provides a clean dashboard to monitor performance. The current MVP focuses on core vault mechanics—deposit, withdraw, and live stats—serving as the foundation for future integrations with protocols like GMX (GLP) and Hyperliquid for real yield and automated hedging.
A SuperApp for Payment and Loyalties
Yield Sphere Mini App is an AI-powered SocioFi companion that simplifies one of DeFi’s most complex protocols: Pendle. Built as a Farcaster mini app during the buildathon, it turns advanced concepts like yield tokenization, principal and yield tokens, and even stablecoin innovation into interactive, conversational learning. With chat-based guidance, structured lessons, and gamified quests, Pendle Agent lowers the barrier to understanding and experimenting with yield strategies — while helping onboard more users and transactions to the Arbitrum ecosystem.
