Rhiva

DeFi

Rhiva is a platform that helps Retail Liquidity Yield Farmers make better decisions by aggregating pools across top Dexes on Solana and ranking those pools from the best yield pool to the least, metrics being volume and fees allocated.

Rhozeland

Consumer Apps

Rhozeland is a productivity studio where creators earn access through contribution, not subscription. Built on Solana, the platform uses $RHOZE utility credits and on-chain Proof-of-Contribution (memo-anchored work history) to power a creator economy with a 75/15/10 revenue split. Features include a real-time marketplace, collaborative Smartboards, Drop Rooms for live sessions, and a tiered Creator Pass system. Rhozeland replaces pay-to-play with prove-to-play — unlocking studio time, networking

RianGlas Energy Green

Climate / Green Tech

Ireland's data centers consume 21% of national electricity. EU CSRD mandates proof of 'Additionality' (new green energy), but legacy REGO certificates are slow and fraud-prone.RianGlas is a B2B DePIN protocol providing real-time Proof of Green Generation (PoGG) on Solana.How It Works:1. Hardware Edge: Industrial-grade Shelly 3EM tamper-evident meters at micro-production sites (farms/SMEs).2. Anti-Fraud (The Moat): Our MET-Correlation Engine cross-references IoT hardware data with MET Eireann wea

Ride Markets

DeFi

Ride Markets is an onchain prop firm built on futarchy. A trader calls a trade, the crowd bets YES/NO using the fund's own coin as the chip, and the treasury executes the call. Winning callers take 30% of trade profit. Losing callers walk away from a $9 bond. Built on Sowellian futarchy — Hanson's "let markets decide" applied to treasury operations, not governance. Live on Solana mainnet with two funds running in private beta.

RIFT - Rapid Integrated Fiat Terminal

FinTech

Rift is a cryptocurrency ATM that enables fast and secure cash-to-crypto and crypto-to-cash transactions directly on the Solana blockchain. It uses decentralized exchange (DEX) technology via the Jupiter aggregator. Users scan their wallet and AML/KYC tier, benefit from real-time asset pricing, and receive SOL or any SPL token instantly, taking advantage of Solana’s high transaction speed and low fees.

RIPSY

Gaming

RIPSY is the first truly casual onchain game on Solana - a hidden-information board game built on the universal Rock-Paper-Scissors mechanic. Pieces move like checkers; their type stays secret until collision, revealed on-chain via MagicBlock. Gasless for players. Figures are Metaplex Core NFTs.

Riptide

Developer Infrastructure

Riptide is an open-source simulation framework for Solana teams. It runs local, reproducible economic stress tests against real Solana programs on LiteSVM, helping builders see how protocols behave under user activity, market shocks, oracle changes, and risky parameters. The goal is to map where your economy breaks before mainnet does.

Rise of the Gorecats

Gaming

A fan-first gaming franchise built on Solana, starting with our live game Rise of the Gorecats. We’re scaling across PSG, Seeker, Steam & Roblox to reach millions of players, while building a fan economy through collectibles, tournaments and $GCATS. By turning players into long-term fans, Gorecats creates a compounding franchise spanning games, content, merch and digital ownership.

RiskClaw

DeFi

Audit-grade autonomous risk-policy enforcement for institutional onchain capital on Solana. DAO treasuries and onchain funds want to delegate trading authority to agents, but If the policy lives on-chain in plaintext, MEV actors front-run it and rival funds reverse-engineer the strategy. RiskClaw solves both: the threshold encrypts at rest in the risk_policy Anchor account, and the agents enforcing it never see plaintext.

RiskMesh

FinTech

RiskMesh is a Solana-based settlement infrastructure for multi-party insurance. It turns separate insurer records into one shared, executable on-chain agreement state. Our MVP uses flight delay insurance as the first wedge: oracle-verified delay events update shared PDA state, and Anchor smart contracts execute pre-agreed USDC settlement atomically across participants in a single transaction.

RitArena

Gaming Infrastructure

There are thousands of AI agents — but no open platform where they compete for real money and anyone can profit from hosting them. 400+ teams built standalone agent games at Monad's Moltiverse — none left reusable infrastructure. RitArena fixes that. Creators build visual battle arenas, set rules and fees, and earn up to 20% when AI bots enter and fight. More arenas mean more agent data, better training, and bigger audiences — a flywheel that locks in creators and players.

riven

Payments & Remittance

Riven is the financial control layer for humans and AI agents on Solana. It lets people manage stablecoin balances, invoices, off-ramps, and payment activity, while giving each AI agent an isolated spending environment with its own balance, permissions, budgets, and transaction history. Agents can safely pay for APIs, data, MCP tools, and services using USDC/x402 without accessing the user’s main funds.

Riverhold

Gaming

Riverhold is a dark-fantasy RPG running inside Telegram — no install, no wallet pop-ups. Combat, raids, guilds, mercenaries, gear, all server-resolved. Solana is opt-in: free to play for everyone. Players who activate the in-game Vault get a real Solana wallet; players who go further open the Tresor to lock-stake $RVRH. $RVRH is already live — deployed on Pump.fun, Jupiter-listed.

Rivo

Marketplace Platforms

Rivo is the stablecoin-native marketplace for real digital products, empowering creators and developers to sell globally with instant payouts and instant access.

RizQ

Consumer Apps

RizQ brings the $1 Trillion global rotating savings market to Solana, replacing human organizers with Solana Programs and an AI coach so communities can save together with zero trust risk.

Roaster

AI Platforms / Agents

Roaster makes agentic actions bettable, starting with prediction markets for Agentic Rap Battles. Agents drop bars, generate full songs, and AI jury settles each battle. Every battle publishes its songs to streaming platforms, where royalties flow to backers and agents forever. Backed by ElevenLabs. Team previously had a startup acquired by Binance's WazirX, ran Brave Browser's NFT launch on Solana, and drove Bonk's early NFT growth.

Rollover

Payments & Remittance

Recurring billing infrastructure that turns any app or API into a subscription business onchain. Plans, allowances, usage, and credits settle automatically in stablecoins across multiple chains via x402, giving builders the Stripe experience without card processors or custody.

ROM

NFTs & Digital Assets

Rom Cards is a programmable media platform that combines AI video generation with blockchain-based remixable IP infrastructure. Users can create characters, stories, memes, and media assets that can be reused, remixed, owned, and monetized across creators and applications.

ROOMZ

Consumer Apps

Fans crave real connection with the artists who inspire them, but current social platforms make those moments shallow and inaccessible. ROOMZ changes that by letting fans unlock 1:1 video experiences with their favorite music artists through raffles, auctions, and exclusive digital moments. Each interaction generates Creator Coins—tokens tied to real artist activity and fan engagement, turning connection into shared value.

Roosta

DeFi

Roosta is an on-chain social savings protocol on Solana, reimagining ROSCAs ("kye" in Korea, "tanda" in Mexico, "sou-sou" in West Africa) for the stablecoin era. Groups pool USDC, smart contracts enforce contribution rules and automate rotating payouts, and every deposit lives on-chain. Most Web3 savings apps optimize for yield; Roosta optimizes for trust between people who already know each other but lack tools to coordinate money safely. Payment history becomes a portable credit signal.

RootLens

Consumer Apps

RootLens is a camera app where anyone can film household tasks and get paid. The footage becomes AI training data for robotics companies. AI guides your recording in real time, automatically masks faces and text for privacy, and blockchain handles data rights and revenue sharing so every creator gets paid fairly.

Rooty.fun

Token Launch / Tokenomics

Rooty.fun is a creator-focused layer on top of Pump.fun that enables streamers to share revenue with their audience. Creator fees are routed to PumpSwap LPs via staking, aligning creators, holders, and liquidity providers. Additionally, Rooty introduces whitelist-based presales to improve distribution and reduce sniper risk, enabling fair, community-driven memecoin launches.

RoundFi

DeFi

RoundFi is a behavioral credit protocol built on Solana. The protocol transforms recurring financial behavior into portable on-chain reputation, allowing DeFi users to access credit with lower collateral over time. Users build reputation through structured savings pools, recurring contributions, and on-chain attestations. RoundFi integrates Solana, SAS, Kamino, and Switchboard, and is currently live on Solana devnet.

Routex

Developer Infrastructure

RouteX is a freshness-aware RPC routing layer for Solana that intelligently directs requests to the best available node in real time. Instead of relying on a single RPC provider, RouteX continuously monitors multiple endpoints for latency, slot freshness, and health. Using high-speed updates from Yellowstone gRPC, it detects which node is most up-to-date and routes requests accordingly. This ensures that Solana applications get fresher data, fewer failed transactions, and consistent performance,

RoyaleCard Arena

Gaming

RoyaleCard Arena is a Solana-based competitive strategy game platform where players build and configure trading agent cards to compete against each other in real-time simulation battles (paper trading). Each card represents cryptocurrency with unique personality and gameplay. Players configure their agent cards behavior like when to buy, when to sell, & how to manage positions all within a 2-minute round window (Best of 3). "What if trading is as fun as playing games" => RoyaleCard Arena

RPC Priority Protocol

AI Platforms / Agents

RPC Priority Protocol is an open-source, drop-in middleware that sits in front of any Solana RPC. It turns DDoS attacks into operator revenue, replaces IP-based rate limiting with portable pubkey reputation, and lets AI agents pay micro-fees via HTTP 402 to receive priority — only when the network is actually congested.ying agents.

rpc-stats

Developer Infrastructure

RPC stats is a continuously running monitoring system that sends controlled test transactions through multiple major Solana RPC providers and measures real world performance. It exposes a live public dashboard backed by on chain proof, allowing developers to make decisions based on objective data instead of assumptions.

Rugburn

Security Tools

RugBurn is Solana's risk-intelligence layer for humans and AI agents. Calibrated 0–100 safety scores, a deployer-history graph that compounds with every scan, and a vendor-neutral MCP server with six tools any agent can call before firing a transaction. Public Containment Zone, no signup.

RugRoulette

Markets & Exchanges

RugRoulette is a prediction market for Solana token survival. Every new token gets an auto-generated binary market - rug or not - with odds shaped by on-chain forensic signals (mint authority, LP locks, holder concentration, dev history) and trader intelligence.

RugTrace Brain

Security Tools

RugTrace Brain is a post-rug investigation engine with persistent scam memory. It reconstructs on-chain fund flows from Solana transactions, matches them against historical case patterns and suspicious wallet behaviors, and generates forensic reports grounded solely in graph facts. It does not recover funds, identify real-world entities, or provide legal conclusions.
