Guild on 0G: Euclid, MeetLinkAI, QuillAI
Welcome to the fifth installment of Guild on 0G—our ongoing series spotlighting the builders advancing decentralized AI using the 0G stack.
Each project featured in this series is helping bring 0G’s Artificial Intelligence Layer (AIL) to life: a modular foundation for permissionless compute, scalable storage, and AI-native services. From autonomous agents to composable protocols, this latest cohort is tackling some of the most complex challenges in distributed intelligence.
In this edition, we’re featuring Euclid, MeetLinkAI, and QuillAI. These three very different projects share a commonality: they are pushing the boundaries of what AI could achieve in a decentralized world.
Euclid Protocol: Liquidity Without Limits
Euclid is building the first Liquidity Consensus Layer (LCL)—a novel infrastructure that enables dApps and chains to access liquidity across all assets, networks, and ecosystems without relying on bridges. From DeFi to RWAs to payments, Euclid aims to eliminate fragmentation at the root and redefine what interoperability looks like.
Core Features
- Unified Liquidity Pools: EuclidFi allows DEXs to operate omnichain pools, enabling seamless cross-chain swaps without wrapping or bridging.
- Cross-Chain RWA Settlement: EuclidRWA unlocks real-world asset access and collateralization across 40+ chains, with near-instant settlement.
- Universal Payments: EuclidPay supports payments in any token, on any chain—dramatically expanding the market reach for dApps.
Why 0G?
- Real-Time State Sync: 0G enables near-instant, verifiable synchronization of liquidity state across chains, without relying on delayed messaging.
- Modular, Low-Latency Architecture: Euclid leverages 0G’s ultra-fast infrastructure to coordinate cross-chain swaps, lending, and payments.
- Trustless Liquidity Access: By integrating 0G, Euclid avoids the need for bridges or wrapped assets while preserving security guarantees.
With 0G, Euclid is turning fragmented liquidity into a shared, composable layer. One that any project can plug into, and no chain has to build alone.
MeetLinkAI: Smarter Connections, Onchain
MeetLinkAI is a networking and contacts CRM designed to help OffChain’s global community of 20,000+ members extract more value from in-person events and online meetups. By blending social discovery with onchain identity, MeetLinkAI brings real-world connection to the next generation of social apps.
Core Features
- Onchain Identity Verification: Users sign with wallets to prove authenticity, creating a secure, blockchain-based alternative to traditional KYC.
- Social Discovery Engine: A Tinder-like interface helps users find relevant connections based on shared interests and opt into contact sharing.
- IRL-First Networking: Designed to encourage in-person and virtual meetups, not just digital chats, fostering stronger real-world relationships.
Why 0G?
- Decentralized Storage: MeetLinkAI uses 0G’s native storage to manage sensitive user data securely, avoiding central points of failure.
- Privacy-First Architecture: The team is exploring how 0G's decentralized AI stack can enhance user privacy and control over data.
- Integrated Infra Stack: The combination of AI compute and native storage made 0G the ideal home for MeetLinkAI’s next phase of growth.
With 0G, MeetLinkAI is turning events into long-term networks, where every handshake, intro, and opt-in becomes a gateway to deeper connection.
QuillAI Network: AGI-Grade Security for the Onchain Economy
QuillAI Network is developing a decentralized system of adversarial AI agents that deliver autonomous, continuously improving security for the onchain economy. From smart contracts to token audits to AI safety, QuillAI is redefining what decentralized threat detection can look like.
Core Features
- Adversarial AI Architecture: Uses reinforcement learning in a red/blue team configuration to simulate attacks and improve defense mechanisms over time.
- Smart Contract & Token Protection: Identifies vulnerabilities, scam tokens, and rug pulls—then alerts users and suggests remediations.
- AI Agent Hardening: Secures AI agents from prompt injections and jailbreak attempts using dynamic threat modeling.
Why 0G?
- Decentralized Compute Infrastructure: QuillAI taps into 0G’s compute marketplace to efficiently scale training and inference for its AI models.
- Native to 0G L1: The protocol is built directly on 0G’s Layer 1 to ensure seamless integration and performance.
- Purpose-Built for AI Security: 0G offers the infrastructure flexibility and scalability QuillAI needs to evolve its models in real time.
With 0G, QuillAI is building an autonomous security layer for the onchain economy—constantly training, testing, and adapting to stay one step ahead of emerging threats.
Guild on 0G
Each project in this cohort contributes to a shared vision: a decentralized, composable, and AI-native internet. Whether through autonomous agents, verifiable compute, or persistent memory, they’re shaping what it means for intelligence to live onchain.
As we continue to build the AIL, we’re looking for founders who are pushing the boundaries of what’s possible in modular AI. If you’re working on infrastructure, applications, or tooling for this new paradigm, we want to hear from you.
