Unruggable

RWAs, Infrastructure, Undefined

Existing hardware wallets are multi-chain, built for every chain, but optimised for none. Solana support always come second, even Ledger delayed SPL token support until 2025. Unruggable is the first Solana-native hardware wallet and companion app, built to make self-custody simple, fast, accessible and fully optimized for Solana. Swap, stake, lend, earn yield, send, and manage assets directly from the Unruggable hardware wallet and app, with native integrations like Jito for optimized transactions, Squads Multisig, Jupiter Lend & Swap, Titan, Anza’s Confidential Transfers, SNS, DeFi Carrot and Privacy Cash all built in. Unruggable gives Solana users the speed and simplicity of a hot wallet with the security of a cold wallet, with a sub 30 second set up. Our companion app is cross platform on every operating system, fully open-source and written entirely in Rust.

upSign

Consumer Apps, Undefined

UpSign brings a human layer to digital collectibles — letting users sign, personalize, and prove ownership moments directly on-chain. Built on Solana and powered by Metaplex Core, UpSign uses a custom Autograph Plugin that attaches verifiable signatures to NFTs, turning them into unique digital mementos. Each signature is stored immutably on-chain and issues a certificate NFT for both signer and owner, enabling creators, collectors, and event organizers to capture meaningful interactions with transparency, speed, and permanence. UpSign is live on mainnet and expanding toward integrations with DAOs, marketplaces, and brands across the Solana ecosystem. Check it out on already on mainnet: https://www.upsign.fun/

UrsusAI - AI Agent & Token Launch Platform

Consumer Apps, Infrastructure

Problem: Despite the explosive growth of artificial intelligence, users on Solana still rely on centralized AI providers and closed ecosystems. Platforms like OpenAI or Anthropic restrict users from creating, owning, or monetizing their own AI agents. Meanwhile, most Solana token launchpads are purely speculative, disconnected from any real AI-driven value. Solution: UrsusAI introduces a new paradigm — the first decentralized AI agent launchpad built on Solana, where every AI agent becomes a self-sustaining micro-economy. Users can create agents through natural language instructions, deploy them as on-chain programs, and connect each to its own SPL token for dynamic value capture. The platform enables: - No-code agent creation** directly on Solana - Choice of AI models and inference providers - Performance-based token valuation via bonding curves - True agent ownership** through on-chain staking, monetization, and governance primitives

VapeCommander vape2earn

Consumer Apps

We'd like to contribute a combination of a bluetooth vape controller and a native crypto wallet to build a cool vape2earn app: Currently the app supports all Storz&Bickel devices (Crafty+, Mighty+, Volcano) and Pax3 ... The crypto wallet offers access to circle's USD bridge (CCTP) , making it easy to onboard people from all other architectures easily. It supports three types of cryptographic modes: Solana, EVM and Interchain The vape2earn function (not ready yet, just paper) should read the vape's internal operation timer, create a timestamp (blockheight hash)-publicaddress-operationtimer zK proof and stores/interact with a prefunded TokenProgram that will "hand out" tokens to the user. So, its literally the first Proof-of-Smoke protocol ever! Check our tg: https://t.me/solana_vape2earn The latest .apk can be found within the "app development" channel Now we have a website-in-the-works too: https://vapecommander.duckdns.org/

Vau1t

DeFi, Consumer Apps, Infrastructure

A new NFT DeFi strategy inspired from JLP. Depositing SOL and minting tokens againast a strategy vault based around Bluechip NFTs on Solana. The Vault generates revenue through: - Token 22 Swap Fee - Token/SOL LP fees - NFT trading strategies - Addtional plugins to the vault like; 1 for 1 swaps, NFT borrows from vault, OTC Trading, NFT Lending The Vau1t is built to compliment collections by holding all the floor NFTs, increasing floor prices and generating additional revenue for the project. Never been done before but it uses already existing practices so we're not inventing the wheel here we are simply apply a new usecase to the process.

Veritas

DeFi, Consumer Apps

Veritas uses markets to rank media. To do this, we built a novel prediction market primitive called inversely coupled bonding surfaces that allows permissionless market creation for as low as $50 of initial liquidity. Traders can go long or short the relevance of content and rebase the reserves of the curves every few hours according to a novel crowd wisdom elicitation mechanism. Losers pay the winners, and relevance snaps back to reality. Content creators earn a cut of trading fees, and traders profit from the early discovery of bangers, all while casual content consumers get the highest signal media feed on the internet.

VERIX

Consumer Apps, Undefined

Our system is a modular, end-to-end carbon credit automation platform that connects IoT sensors, AI agents, and blockchain payments into one seamless pipeline. Built with autonomous Python agents orchestrated via JSON-RPC, it handles everything from live emission tracking (via MQTT) to marketplace optimization, SOL-based payments, and compliance resets. The backend leverages PostgreSQL as a single source of truth, while the Next.js frontend offers real-time chat interaction, purchase flow, and wallet integration. Powered by Solana for fast, verifiable transactions, the architecture ensures transparency, automation, and market efficiency—bridging real-world carbon data with decentralized finance.

Vertra

Infrastructure

We started Vertra with a clear target: help New York City’s DOB ecosystem by stopping the cycle where elevator companies rack up fines over one hundred thousand dollars just to get inspections done. Our first goal is to streamline compliant, verifiable inspections and maintenance records, creating immediate savings and a sustainable revenue engine for us. From there, we’ll scale to enhance communities and states that lack consistent inspection regimes, bringing simple surveys, transparent on-chain records, and fair payouts to mechanics and riders alike. Vertra is building the Building Compliance Safety layer of the internet—beginning with elevators in NYC and expanding everywhere buildings and people move.
