Autonomous. Secure. Focused. Infrastructure for financial agents that never sleep and never get distracted.
StableGuard is autonomous cross-chain stablecoin depeg protection. When UST/Terra collapsed, $40B disappeared with no automated warning system — protocols kept accepting bad collateral because nothing was watching fast enough. StableGuard cross-checks two independent data sources before acting — a Chainlink price oracle and on-chain DEX data — avoiding the false alarms that plague single-feed monitoring bots. When confident a depeg is real, it automatically fires a Chainlink CCIP alert that can broadcast to multiple destination chains at once, triggering protective action before a human even notices. It doesn't stop a stablecoin from collapsing if it's genuinely dying — nothing can — but it stops the collateral damage from spreading to protocols and positions that had nothing to do with the original coin.
RWA infrastructure protocol building and operating energy storage systems, generating real revenue
Powers Protocol allows startups to create bespoke on-chain governance flows: separate powers in org, create checks and balances between roles, encode nested relationships between orgs and RBAC for deliberation channels. Create an org in 30 minutes using claude skill (+ RAG & MCP); AI agent compatible, native support for Account Abstraction.
The competitive allocation layer for the programmable economy.
EdenFi is a global money app connecting Africa and the diaspora to easy finance.
Agentic Growth for Brands and Creators
Clearstone is the permissioning layer for institutional DeFi. We turn battle-tested lending protocols like Morpho, Euler and Kamino into KYC-gated, non-custodial markets that meet AML, FINMA and MiCA requirements. Winner of StableHacks ($100k + pilot with AMINA Bank), hosted by Tenity, the Swiss fintech VC backed by SIX and UBS, and now shipping on Robinhood Chain.
Pinaivu is private, verifiable AI for healthcare and medical R&D, built on Arbitrum. Independent GPU operators compete in a real-time auction to serve each prompt, prompts are encrypted end-to-end so no one not even the operator can read patient or research data, and every response produces a cryptographically signed, on-chain-auditable receipt. Payments settle trustlessly on Arbitrum and records are archived to IPFS confidential and provable AI, delivered via a chat app and an enterprise API.
Verus provides the BEST possible execution for perp trades across 100+ markets
Personalized agents to run delta-neutral basis trade strategies
Hero Network is the audit and verification layer for AI agents and physical AI. As autonomous agents and robots take on consequential work, the record of what they actually did is missing. Our Proof of Action primitive turns every material action an AI takes, an agent decision or a robot movement, into a tamper-evident, per-action record that any customer, insurer, auditor or regulator can verify independently, for a fraction of a cent, while the AI's rules stay sealed. Every record climbs a four-level trust ladder, from a signed log, to hardware-attested execution, to on-chain anchoring on Arbitrum, to zero-knowledge proofs. The protocol has no token and no admin keys, with roots on-chain. This opens a USD 265 billion market. Today, testing, inspection and certification firms such as SGS, Bureau Veritas, DNV, TÜV and BSI verify that a system meets safety and quality standards, then issue a certificate: a stamp valid at a single point in time that cannot cover how the system behaves once it is deployed. Yet the EU AI Act and the incoming EU Machinery Regulation now require in-service logging and human oversight for AI-enabled systems, which a one-time certificate cannot satisfy. Hero is the continuous, in-service evidence layer those firms resell, and the deployers they certify buy directly. We anchor the world's AI actions on Arbitrum.
