Aurion is a non-custodial credit meta-layer for DeFi. It sits above existing money markets Aave and Compound, and introduces a unified credit identity, cross-protocol risk aggregation, and more.
https://tortuga.estate/ Tortuga brings institutional real estate bonds on-chain — existing, regulated, cash-flowing securities. We are a Luxembourg-incorporated platform connecting on-chain capital with institutional real-world investments, combining TradFi structuring discipline with crypto-native distribution. We convert ISIN-coded, bankruptcy-remote real estate debt instruments (RELINCs) into permissioned on-chain tokens, wrapped through ring-fenced Luxembourg securitisation compartments. These are bankable assets previously accessible only to HNWIs through private banks and wealth advisors — now available to on-chain treasuries, vaults, and sophisticated crypto-native allocators. Our pipeline is powered by Estating: our Luxembourg-based origination partner — operating since 2018, PwC–audited, with $60M+ structured across 20+ deals, zero principal losses, and 5–28% IRR.
Confidential Sealed-Bid Auctions
Live proof pages for Arbitrum/Base contracts, showing current permission state: owner, proxy admin, implementation, pause state, and Safe config.
ACHIVX is the financial identity layer for autonomous agents. Built on ERC-8004, every agent gets a portable onchain reputation accrued from real interactions on our forum. x402-style endpoints then price and gate access based on score. Live on Arbitrum and Robinhood Chain.
Autonomous AI agent monitoring Arbitrum DeFi (DeFiLlama, Uniswap v3, Aave v3), producing a 0-100 sentiment score and recording each report immutably on-chain via a Solidity contract.
X-platform Survival MMORPG w/ unique gameplay-mechanics & “inGame DeFi” (various payment methods & Yield Farm) to be “Self-Sustaining” economic, allowing players to earn through Player Supply & Demand
Kabon is an AI treasury copilot that helps users discover, evaluate, and allocate capital across fragmented DeFi and tokenized asset opportunities on Arbitrum.
Andromeda Core is a Verifiable Reputation Layer that transforms on-chain behavior into actionable TrustScores using the AVIP protocol. By utilizing Shannon Entropy for Sybil detection and asymmetric temporal decay, we provide the Arbitrum ecosystem with a tamper-proof infrastructure to audit contributor integrity and secure decentralized governance.
The BVCC Hook Analytics Dashboard — a full-stack Node.js + HTML application that scans all 4 networks (Arbitrum, BSC, Base, Ethereum) in real-time using eth_getLogs, discovers active pools
Private programmable finance for stablecoin cashflow, powering spending, credit, BNPL, and automated payments on PayFi rails.
Omniflow is an omnichain execution layer for DeFi. Today, cross-chain users must bridge assets, wait, switch networks, and manually interact with a destination protocol. Omniflow removes that friction by letting a user start from one source chain and trigger execution on a destination chain in a single flow. For the Arbitrum Open House Buildathon, Omniflow demonstrates a cross-chain liquidity launch flow powered by LayerZero V2 + compose. A user sends an OFT from a source chain, and the message triggers destination-side execution on Arbitrum, where liquidity can be created and seeded. This launchpad flow is a proof of execution, not the final product. The broader goal is to make cross-chain DeFi feel like one unified environment by turning cross-chain messages into protocol actions: liquidity launches, pool funding, vault deposits, and eventually AMM execution.
