Prob Trade

Markets & Exchanges

ProbTrade does for prediction markets what Uniswap did for DeFi and pump.fun did for token launches — a native single-pool AMM where anyone trades, plus permissionless creation where anyone launches a market in 60 seconds with $100 USDC. Live on Solana mainnet today. Solves the $40M/year extraction Polymarket bleeds to arbitrage bots — by replacing N independent binary order books with one multi-outcome pool where prices sum to 1 by construction. Users can also trade polymarket markets using us.

ProbX

DeFi

ProbX is a Solana-native AI agent prediction market where autonomous agents create, analyze, and trade YES/NO markets using on-chain activity, social sentiment, and real-time external signals.

Project Aegis

AI Platforms / Agents

Project Aegis is an AI-native, AWS-centric incident management platform that modernizes security operations. Powered by Amazon Bedrock agents, it automatically triages findings, generates explainable reports, and guides remediation through an interactive AI assistant. Built serverless on AWS, it integrates natively with Security Hub to reduce MTTR, improve visibility, accountability and decision clarity while maintaining audit-ready compliance across the full incident lifecycle.

Project Earthspan

Real World Assets (RWA)

Project Earthspan is a Climate RWA platform on Solana. We tokenize global environmental impact into "Impact Metres," empowering the Ownership Generation (16-35) to lead recovery as "Burwa Bosses." Using Solana Token Extensions, our Sovereign Engine captures protocol value to fund five critical pillars: Field Workers, Treasury, Land Acquisition, Innovation R&D, and Resource Resilience. Our modular architecture is built for institutional liquidity and adaptive scaling.

Project Overlord

DeFi

An AI-powered intent execution layer that eliminates friction in cross-chain onboarding to Solana. Users describe their goal in plain English, and Overlord orchestrates the entire flow: intent parsing → route discovery via LI.FI → bridge/swap execution → Solana delivery. No bridge tutorials. No token hopping. Just one sentence and one confirmation.

Project RPM

AI Platforms / Agents

Project RPM transforms product-market fit discovery through AI-powered synthetic user testing. Real behavioral data from user participation generates AI personas that mirror actual market behavior. Enterprises receive actionable insights — replacing costly guesswork with a Pearson-correlated behavioral engine, powered by Solana's x402 micropayment infrastructure.

Project Shadow

Data & Analytics

Project Shadow is a privacy-first AI workflow layer for sensitive operational teams. It helps users structure cases, decisions, follow-ups, and internal knowledge without exposing more context than necessary, combining practical automation with clear human oversight.

Proof

EdTech

Proof is a Solana-based assessment platform where tutors host courses and encrypted exams with Arcium, and students take assessments with verifiable results recorded on-chain. It’s a platform where students can prove what they know through verifiable on-chain results, closing the trust gap between learning and achievement.

PROOF by FRAME

Consumer Apps

PROOF turns raw collectible card submissions into portable proof through AI-assisted review, community consensus, and on-chain identity.

Proofcert

EdTech

A decentralized, privacy-preserving credential registry that allows institutions to issue and verify certificates.

ProofChain

Security Tools

ProofChain is a certificate verification app that generates a SHA-256 hash from a certificate and checks whether that proof exists in a trusted registry. It shows how proof anchoring in the Solana style can make credential verification instant, tamper-evident and easy for institutions, students and recruiters. The current prototype focuses on a simple issue-and-verify flow: upload a certificate, generate a unique fingerprint, store the proof, and later verify if the same file is authentic

ProoFi

Identity & Privacy

ProoFi & ALIBI ProoFi is a zero-knowledge credit primitive on Solana. Wallets prove their creditworthiness on-chain in a single transaction without revealing who endorsed them, what their score is, or anything about their wallet history. ALIBI is the first dApp built on ProoFi: a privacy-preserving USDC lending pool where verified borrowers post as little as 60% collateral and pay 25% lower interest — gated entirely by ProoFi's on-chain credit credentials.

Proofjar

Consumer Apps

ProofJar is a high-stakes accountability layer for Solana where friends stake SOL on real-world goals and use social consensus to slash whoever breaks the rules first.

Proofline

AI / ML Models

Proofline is an offline proof-of-work application designed for field operations (like solar installations or remote engineering) in low-connectivity areas. It enables workers to capture evidence (photos, voice notes) and uses the QVAC SDK to run a 100% on-device AI pipeline—comprising OCR, ASR, RAG, and an LLM—to instantly verify the work against Standard Operating Procedures (SOPs). Once the device regains connectivity, a cryptographic hash of the verified evidence bundle is submitted to a Sola

Prooflink

AI Platforms / Agents

Chainlink for human capital: The skill oracle for AI hiring agents with on-chain attestations, x402 micropayments, and MCP-native.

ProofMesh Guard

Developer Infrastructure

Solana-native trust permits for agent and DAO treasury payouts. ProofMesh Guard checks payout intent, anchors RELEASE/CAP/BLOCK permit PDAs on devnet, and lets approved permits execute while blocked payouts become verifiable evidence.

Proof of Focus

AI Platforms / Agents

Proof of Focus is a Solana-native behavioral execution layer for crypto users. It detects high-risk trading patterns before execution and delivers lightweight warning, cooldown, and override flows designed to reduce impulsive decisions under pressure.

Proof of Good

Social / SocialFi

A SocialFi platform on Solana where companies turn passive CSR budgets into real, measurable community impact. Instead of reports nobody reads, companies fund on-chain missions such as clean-ups, food bank shifts, tree planting. Users submit verified proof, split the SOL reward pool, and build a soulbound on-chain reputation. Gamified, transparent, and built to make doing good rewarding.

Proof of Human

AI Platforms / Agents

Anti-sybil AI. Contribute to community-powered heuristic brain. Powered by Solana and QVAC.

Proof of Inference

AI Platforms / Agents

A Solana protocol that creates cryptographic proof that a specific AI model produced a specific output. Model owners commit their weights on-chain. Users submit encrypted inference requests processed by Arcium's MPC network. The result is written immutably to Solana — any smart contract can verify it via CPI. AI agents can now act on-chain with auditable, tamper-proof inference instead of blind trust.

Proof of Justice

Governance & DAOs

Proof of Justice is a crypto-native arbitration and reputation system that creates an enforcement layer for Web3. Built on ArbiLayer, it enables dispute resolution between wallets and records outcomes on-chain. Compliant actors build reputation, while those refusing arbitration are flagged, making trust and behavior visible across DeFi, payments, and DAOs.

Proof-of-Reality

DePIN

A hardware camera system that proves a video could not have been generated by AI — any AI would need to synthesize footage matching a specific Solana blockhash within 1600ms, the time window of a single blink cycle. An OLED display shows a live hash seeded by that blockhash, which the camera reads optically frame-by-frame to create an unforgeable link between the footage and the chain. Anyone can verity the generation time.

Proof Of Ship

AI Platforms / Agents

A builder credit platform where hackathon prizes collateralize on-chain credit lines. Backers fund builders while AI agents—Scout, Underwriter, and Verifier—analyze projects through x402 nanopayments on Circle Arc. Built on Solana with SNS identity proofs, Cloak shielded staking, and LI.FI bridging across 7 ecosystems. Powered by local-first AI via QVAC. Live on devnet with 7 confirmed transactions covering the full credit lifecycle.

Proof of War

Gaming

Proof of War is a mobile base-building strategy game for Seeker where players build war bases, train armies, raid rivals, join clans, and compete in optional SKR-powered ranked modes and staked clan wars.

Proof Pass

Payments & Remittance

ProofPass lets anyone pay anyone on-chain without either party ever knowing the other's wallet - and the payer still gets a cryptographic receipt they can show to anyone as proof, without revealing a single address. "Think of us Stripe, but for privacy-first crypto payments." Payments become as private as cash, yet as auditable as a bank statement. No mixers, no custodians, no trust required except the service you already choose to use.

ProofPass

Developer Infrastructure

ProofPass is a Private Proof-of-Builder SDK that prevents Sybil attacks and fake developer profiles in Web3 ecosystems. It enables elite developers to cryptographically prove their on-chain deployment history and protocol integrations using Circom ZK-SNARKs and domain-bound nullifiers, without doxing their mainnet utility wallets. Our infrastructure serves as a verifiable, privacy-preserving credential firewall for DAOs and hackathons, integrating directly with Solana Attestation Service.

ProofPay

Payments & Remittance

Loyalty is broken: every merchant builds their own siloed program, and your purchase history can't follow you. ProofPay flips it. Pay any Solana merchant in USDC and atomically earn a portable on-chain attestation you own. Walk into the next ProofPay merchant and their discount auto-applies — no signup, no integration between brands. One Anchor instruction does it all. Built on Solana Pay + Solana Attestation Service. Live on devnet.

Proof-please (indie pool)

AI Platforms / Agents

Proof, please! turns creative contributions into portable on-chain reputation. Submit code, art, music, 3D, writing , Claude scores it 0–100, the score mints as a non-transferable Token-2022 SBT to your wallet, and if a project funded an escrow, SOL pays out automatically, all in one oracle-signed transaction. Every project, score, REP token, and payout is a real Solana account verifiable on Explorer. Two layers: reputation that can't be bought, SOL that flows on top of it.

ProofWork

Consumer Apps

ProofWork is a trust protocol on Solana with two primitives: programmatic escrow and soulbound reputation. Funds lock in on-chain PDAs code releases them, not a company. Every completed job mints a non-transferable NFT review into your wallet using Token-2022. No platform can delete, edit, or hold your reputation. We shipped a full freelance marketplace as the first app on the protocol live on devnet with end-to-end escrow, dispute resolution, and soulbound reviews. One protocol, many markets.

PROPLY

Real World Assets (RWA)

PROPLY is Australia's first property marketplace built for crypto-native buyers — connecting digital capital with premium new developments via Solana Pay.
