PraivateDAO

Governance & DAOs

PrivateDAO is a Solana governance and treasury protocol for private, execution-safe decision making. It combines commit-reveal voting, zk_enforced verification paths, confidential payroll and bonus approvals, REFHE-gated encrypted payout execution, and a live wallet-connected product surface with reviewer-visible runtime evidence. The system is built for DAOs and on-chain organizations that need private voting, secure treasury actions, and auditable governance operations without exposing l

Praxa

Consumer Apps

Praxa is the coordination layer for hyperstitions - ideas that become reality through collective belief and action

Prax - AI API Credits Marketplace

Marketplace Platforms

Prax is a decentralized marketplace for unused AI and API compute credits, where developers and organizations can trade surplus credits through auctions and on-chain settlement. The platform enables tokenized compute liquidity, transparent pricing, and efficient access to AI credits.

Predacy

Consumer Apps

Every trade on Polymarket or any prediction market is fully public, your wallet, size, position etc are permanently visible onchain. Copy traders and bots monitor wallets in real time, they front run retail orders, and exploit visible flow Most retail traders with genuine opinions on political or macro events simply don't participate because they don't want their identity permanently linked to their positions. Have shared about this on my article about the "French Trader from 2024 US Election"

PreDataPool

IoT / Edge Computing

Predatapool brings Cloudflare-like request coalescing to the Solana machine economy. In IoT and edge environments, many devices, sensors, vehicles, and AI agents repeatedly request similar data within short freshness windows. Predatapool groups that demand, performs one verified fetch when possible, enables encrypted reuse, and uses Solana for programmable settlement, reuse receipts, and provider payouts.

Predict and Launch

Consumer Apps

PNL is a coordination market for ideas — live on Solana mainnet. Anyone, anywhere, posts an idea for $2. A global market of believers and critics decides, with real SOL, whether it deserves to launch. YES → token auto-launches with pooled liquidity; founder earns ongoing royalties. NO → critics split the pool, paid for filtering noise. Every idea, funded or not, joins a permanent on-chain library. Conviction in place of attention. The credible v2 of the launchpad, for the AI era.

Predicta Trade

Consumer Apps

Predicta Trade is a signal-driven, Solana-first memecoin trading terminal with predictive entry/exit indicators, preemptive risk analysis and warnings, real-time charts and holder audits. Affiliates are paid instantly on-chain when sub-affiliates trade.

prediction marketplace

AI Platforms / Agents

Agent Prediction Market — The first prediction marketplace where AI agents are the only bettors. AI agents autonomously browse markets, search the web for evidence, generate reasoning, and place bets — no human places a single bet. Ever. Five agents with distinct personalities compete for prediction accuracy. Markets auto-resolve via web search. Winners get paid automatically. The reasoning data we collect is a dataset no one else has. This isn't a gambling platform. It's infrastructure for the

Prediction-Royale

DeFi

Prediction Royale is a "Battle Royale" of financial predictions based on the price of SOL/USD in real time. Unlike traditional prediction markets, users compete in elimination rooms where market analysis and survival are the key to taking the jackpot.

predictumx

DeFi

PredictumX is a new primitive for prediction markets: conditional bets powered by bin-based liquidity. Users can combine multiple outcomes into a single position (similar to parlays), unlocking higher multipliers like 3x or 10x. Under the hood, liquidity providers act as the house, pricing and backing these combinations through structured liquidity pools. The result is a faster, more scalable way to trade complex predictions, with a simpler and more game-like user experience.

PredictX

DeFi

PredictX is a decentralized prediction market protocol on Solana where anyone can paste an X (Twitter) URL to instantly spawn a Yes/No market. An AI oracle powered by Claude analyzes tweet content and on-chain signals to resolve markets trustlessly. Users trade positions with SOL, prices move via AMM, and every outcome is settled on-chain with full transparency.

Predikt

Developer Infrastructure

Predikt is a unified API stack that acts as the coordination layer for liquidity, access, and cross-chain execution across prediction markets, unlocking composability and enabling the Predikt Protocol, where market positions become tradable primitives across DeFi. It aggregates markets across venues, routes orders to optimal execution paths, and abstracts complexity for seamless integration.

PREDIX

DeFi

Predix is the plug-and-play infrastructure for prediction markets. We enable any company to launch its own market without building the tech, liquidity, or operations from scratch. Like Nasdaq for market infrastructure and Stripe for ease of integration, Predix removes barriers to entry and lets clients focus on distribution, brand, and user acquisition. This opens the door for thousands of new operators, niches, and growth channels. Team previously at PayPal, Apple, Meta, Netflix, DAZN...

PredX

DeFi

Predix - a white-label prediction market SDK on Solana. Operators embed a ready-made widget on their site and instantly offer prediction markets with on-chain settlement, built-in liquidity, and customizable branding. Like Stripe, but for prediction markets.

Prflght

PrimalBet

Consumer Apps

PrimalBet is a Solana arcade-combat jackpot game where one entry triggers three independent winning systems: a timer-based grand pool, a per-run roulette gated by your skill, and a weekly raffle. Built mobile-native for Solana Seeker. - Play, Persist, Prevail -

Prism

DeFi

PRISM is a Solana-based meme coin intelligence platform designed to help traders make safer and smarter investment decisions. It addresses key problems in the meme coin ecosystem such as rug pulls, whale-dominated supply, and fragmented data across multiple tools by providing a single unified interface for analysis. The platform offers features like a token safety scanner that generates a score based on liquidity, authorities, and holder distribution, creator intelligence to analyze the history

Prism Protocol

DeFi

PRISM (Programmable Risk & Income Structured Markets) is a protocol that changes credit into structured, tradable risk layers. Users choose exposure (Prime, Core, Alpha) within pooled credit vaults instead of putting money into individual loans. Cash flows follow deterministic waterfall logic, and tokens that stand for each risk layer can be traded. This makes it possible to see, trade, and price credit markets on-chain in real time.

Privacy Cloak

Identity & Privacy

- I’m building Universal Privacy Layer, infrastructure that enables private transactions across public blockchains. Today every wallet balance, trade, and transaction is fully visible, which makes it risky for traders, funds, and institutions to operate on-chain. - Our system uses zero-knowledge proofs, stealth addresses, and private relayers to hide balances and activity while transactions still settle normally on the blockchain.

Private Intent

Identity & Privacy

Private Intent is a future-proof financial infrastructure on Solana that combines the power of Ika (MPC) and Encrypt (FHE) to create a completely private, bridgeless cross-chain trading ecosystem. The project allows users to instantly exchange native assets (such as BTC, ETH, and SOL) without ever exposing their transaction details to the public or the security risks of traditional bridges.

PrivatePayroll

DeFi

Confidential on-chain payroll powered by Umbra Privacy SDK on Solana

PRIVEX

DeFi

Programmable privacy on Solana. Using Dual-Key Stealth Address Protocol (DKSAP) and Light Protocol's ZK-compressed derived pool vaults, senders transfer SPL tokens or native SOL to one-time stealth addresses stored as ephemeral Merkle leaves. Recipients claim privately via relayer — zero gas required. Viewing Keys enable selective disclosure for compliance. Instant, audit-ready private transfers.

PrivyBag

Identity & Privacy

PrivyBags enables private tipping for Bags.fm creators on Solana. Instead of direct wallet-to-wallet transfers (visible forever on explorers), tips flow through a Vault PDA intermediary -- breaking the sender-recipient link while remaining fully auditable. Fans search creators by Bags username or Wallet Address and tip instantly; creators claim funds easily via dashboard. Built with Anchor (Rust) + Light Protocol on Solana Devnet.

Privyra

DeFi

Privyra is a sealed-bid auction protocol for native cross-chain assets. Sellers list real BTC, ETH, or any native asset. Bidders submit encrypted bids no one sees the amounts, not even the protocol. When the auction closes, the winner is selected entirely on encrypted data, and Ika's dWallet network delivers the asset to the winner natively on its home chain no bridges, no wrapped tokens, no custodians.

Prize Bots Online

Gaming
