SauronID

Identity & Privacy

SauronID is a cryptographic agent-binding layer for AI deployments. A self-hostable Rust service that signs, leashes, and audit-anchors every action an AI agent takes, so a compromised agent cannot replay tokens, mutate requests, escape its intent, or silently swap its runtime. Sixteen out of sixteen known agent attacks blocked in under five milliseconds, with every action anchored to both Bitcoin and Solana for tamper-evident audit.

Savings Ladder

DeFi

SavingsLadder is a Protocol-as-a-Service that turns solo saving into a social game group accountability, ~7-8% APY via Marinade Native staking, transparent on-chain fee splitting, and zero smart contract risk on Solana.

SaySo

Markets & Exchanges

Capital-efficient prediction markets on Solana. YES/NO positions on culture, sports, crypto and politics become productive collateral - borrow stablecoins against live exposure, loop for leveraged conviction, exit any time. A protocol-enforced LLTV decay invariant forces every leveraged position to unwind before resolution, eliminating the single-block bad-debt vector that's blocked every prior design. Capital stays productive. Conviction stays on the board. Betting. But Better.

ScholarFi

EdTech

Our vision is to redefine how academic effort is recognized and valued by transforming student achievements into verifiable, on-chain assets. Instead of progress being confined to traditional grading systems, we enable a model where every meaningful milestone can be recorded, owned, and leveraged by the student. By leveraging blockchain technology, we aim to create a transparent and trustless ecosystem where institutions, students, and partners are aligned through incentives. Students gain owne

Scholarship DAO

Governance & DAOs

A community-governed, on-chain scholarship protocol built on Solana.

Scooby

Developer Infrastructure

Scooby is an AI powered Solana smart contract auditor that detects vulnerabilities in Anchor programs and generates verifiable on chain security attestations, helping developers prove protocol safety before launch.

SCoolCoin

Consumer Apps

SCoolCoin is an educational reward platform that motivates students through a token-based system. Students earn tokens for good grades, competitions, social activity, and positive behavior, then exchange them for discounts and rewards from partner brands. The project combines education, gamification, and modern technology to improve student engagement, support schools, and help build a smarter and more innovative future generation.

SC-Portal

AI Platforms / Agents

This project is an AI-powered multi-tenant School SaaS platform built with Python and Streamlit to help Pakistani schools digitize academic management and grading workflows. The system includes a Master Admin Panel, School Portal, and Student/Teacher App for managing students, teachers, classes, analytics, and AI-based answer sheet grading. It uses OCR and Google Gemini AI to automatically extract and evaluate handwritten assignments and exams. A key innovation of the platform is its blockchain

Scrolly

Gaming Infrastructure

AI generated game platform that publishes to a mobile feed, featuring leaderboards and smart contract integrated game tournaments.

Scrooge

DeFi

SWIM is an open-source onchain framework that creates a unified way to use DeFi protocols. Scrooge is the commercial product on top: yield comparison, strategy simulation with full cost transparency, and non-custodial execution. We integrate e.g. Kamino, Jupiter, Loopscale, and Jito, and every position users create through Scrooge is a deposit into those protocols. Comparison and simulation are free, with paid tiers for monitoring, risk management and automations, as well as an API for agents.

Sealbid

Token Launch / Tokenomics

A privacy-first sealed-bid token auction protocol on Solana where bids are encrypted end-to-end and only revealed after the sale closes.

Sealed Agent

AI Platforms / Agents

Sealed is an AI agent for B2B deal execution on Solana. Business owners describe deals in natural language. The agent structures terms into milestones, locks USDC in escrow, and coordinates releases that both parties sign off on. A web2 wrapper hides wallets, gas, and DeFi complexity so non-technical users can transact without learning blockchain. Every closed deal compounds a portable on-chain reputation.

seawatch

AI Platforms / Agents

SeaWatch is a maritime AI agent platform where Claude monitors ships 24/7 via real-time AIS data, instantly alerts crews and operators to drift, weather, and route-deviation risks, and lets sailors trade goods and services P2P with USDC escrow at any port. Agents autonomously pay each other for premium data using the x402 protocol (HTTP 402 → Solana USDC → retry), so analysis keeps running while humans sleep. Built on Next.js + Solana + Claude, targeting 100K+ ships and 1.89M+ sailors

Seco

Wallet Infrastructure

Wallet.

SecondSet

Wallet Infrastructure

SecondSet is a self custodial stablecoin treasury platform for teams paying vendors and contractors in USDC or USDT. It turns basic wallet activity into a controlled accounts payable workflow with payment requests, invoice attachments, role based approvals, mobile signing, separation of duties, and audit ready records linking each approval to the on chain transaction.

SecureTrust

Real World Assets (RWA)

TrustScore is a platform that analyzes Solana addresses on the blockchain to help people detect fraud, rug pulls, and any other malicious activities. TrustScore provides a real-time risk assessment of any Solana address, assigning a trust score ranging from 0 to 100.

SecureYourSOL

Security Tools

I built SecureYourSOL, a non-custodial Solana vault where users deposit SOL and instantly receive a 1:1 non-transferable secSOL claim token. Using Token-2022, I implemented on-chain withdrawal policies enforced directly by the program — configurable instant limits, timelocks, multi-guardian approvals (e.g. 2-of-3), and freeze windows — so even if the private key is compromised, large exits are delayed, visible, and controllable without touching the user’s hot wallet.

Seedless

Consumer Apps

Simple and private passkey wallet on Solana. Face ID sign-in, stealth-address sends, no seed phrase.

Seedling

FinTech

Yield-bearing allowance, on-chain. Inspired by the Brazilian décimo terceiro (the 13th-month salary). Seedling teaches kids patience compounds. Parents deposit USDC once; the vault earns ~8% APY on Kamino; kids get a monthly allowance plus a year-end bonus from accumulated yield. We reward patience, not consumerism. While Greenlight charges $240/yr, Seedling charges nothing, we share 10% of yield. Parent-custody is architecturally enforced: the kid never holds a key.

Seeker PAY

Payments & Remittance

Seeker Pay is a mobile-first crypto payments platform built for Solana Mobile, enabling seamless real-world transactions without additional hardware. It transforms any smartphone into a full payment terminal, allowing users and merchants to send and receive payments via QR codes, NFC (tap-to-pay), Bluetooth (nearby payments), and domain-based transfers (.skr). The app introduces a powerful Shop Mode, designed for merchants to instantly accept payments, track live transactions, and manage sales

Seekerthon

Consumer Apps

TikTok-style hackathon voting gated to Seeker Genesis NFT holders, with $SKR staker vote weighting and trustless Solana prize escrow.

Seeker Vault

Security Tools

Seeker Vault is a zero-knowledge, local-first encrypted storage solution designed exclusively for the Solana Seeker. It secures seed phrases, private keys, and sensitive files using AES-256 encryption. By leveraging the Mobile Wallet Adapter (MWA), the app enables 3-layer authentication (PIN, Biometrics, Wallet) and unique deterministic backup recovery tied to the user's wallet signature. No servers, no tracking—just pure digital sovereignty on your device.

Seel

ZK / Crypto Research

Privacy-preserving income attestations for DeFi on Solana. Users connect bank accounts via Plaid and generate client-side zk proofs proving their income exceeds a threshold - without revealing salary, employer, or financial history. Verified users receive a Soulbound SPL Token-2022 credential that enables higher LTV borrowing in DeFi.

SEER

Developer Infrastructure

Tenderly for Solana. We present a Solana development RPC which gives your tests superpowers. For each transaction, you will see: - Execution through your source code - Account state changes at the moment they happen - VM execution details across all programs - Account read information, even for closed-source programs This is a first step towards comprehensive, end-to-end development infrastructure to make Solana the best place to build reliable, composable software.

Seeshelf

Social / SocialFi

SeeShelf is a high-fidelity digital management ecosystem designed for serious collectors of physical media, from rare Vinyls and 4K Steelbooks to Trading Cards.
