Sentrii

Security Tools

Sentrii is an AI-powered threat hunting and security analysis agent. It analyzes suspicious links, files, repositories, and wallet interactions in isolated environments before users interact with them, detecting phishing sites, malicious code, wallet drainers, and social engineering attacks. Sentrii helps developers, traders, and crypto users understand risk before assets or machines are compromised.

Sentrix

AI Platforms / Agents

Sentrix is a developer SDK and real-time dashboard for monitoring, auditing, and controlling autonomous AI agents transacting on Solana. With a 5-line SDK integration, Sentrix intercepts agent transactions before they hit the chain enforcing spending limits, detecting anomalies like spend velocity spikes and unauthorized program calls, and providing an instant kill switch to freeze rogue agents. Live on devnet with real on-chain transactions and Solana Explorer links. SDK published on npm.

Sentry402

RegTech & Compliance

Citation-bound wallet risk + a pre-flight firewall for AI agents. Paste any wallet (EVM or Solana) → get a regulator-defensible dossier where every flag links to the GoldRush or Helius API call that produced it. Same engine ships an x402-priced verdict ($0.02) for ElizaOS agents to call before signing transfers. No API key, no $30K enterprise contract.

Sentry Node

DePIN

Sentry Node is an autonomous physical security agent that detects unauthorized presence using TensorFlow AI and enforces financial penalties on Solana — no humans in the loop. Operators register via Dodo Payments with just a card, bridging fiat to on-chain staking instantly. The security vault is funded cross-chain via LiFi. Camera sees the threat. Chain enforces the penalty. Automatically.

seri_protocol

DeFi

Seri is a permissionless price discovery protocol on Solana. Any tokenized asset, tokens, fractional NFTs, RWAs enters an auction where the market collectively finds the fair price. No bots, no insiders, no first-mover advantage. Inspired by Uniswap's Continuous Clearing Auction, built natively for Solana.

Serout: Intelligent Onchain Routing

AI Platforms / Agents

Serout is an intelligent onchain agent on Solana that routes, simulates, and executes money transfers based on user intent. Users can input a wallet, token, or bank transfer request, compare optimized transaction routes, simulate outcomes before execution, and complete transfers transparently. Powered by Jupiter routing, Serout simplifies swaps, remittances, and P2P crypto payments through an agent-first UX.

session.money

AI Platforms / Agents

The trading wallet for AI agents. It asks for a spending session, you approve once, it acts onchain within the cap. Never hand AI your keys.

Settld

DePIN

Settld is a decentralized payment network that enables pay-per-request monetization for any HTTP API - no billing systems, no user accounts, no payment processors. Built on HTTP 402, operators stake to join the network, settle payments on-chain, earn rewards, and get slashed for underperforming. No middlemen. Just pay and get access.

Settle

Payments & Remittance

AI agents now handle real money booking flights, paying APIs, calling services on your behalf. Bank statements show only the merchant. Not what was authorized. Not why it was allowed. Settle puts that meaning on-chain. Every payment commits four BLAKE3 hashes receipt, reason, policy snapshot, request context. Anyone re-derives them in their browser. Send USDC to a @handle, hire AI agents with scoped rules, verify without us. Anchor 0.31, 14 ix, SDKs in TS/Python/Rust, Ika cross-chain.

SettleDesk: Sovereign Financial Intelligence

AI Platforms / Agents

SettleDesk is a local-first, autonomous Accounts Payable workstation built for enterprise treasuries. By combining QVAC’s on-device AI reasoning with the WDK Solana module, SettleDesk allows companies to ingest, audit, and settle invoices entirely offline. It solves the critical enterprise problem of data privacy—ensuring highly sensitive vendor contracts and internal approval threads never leak to centralized cloud LLMs. SettleDesk pioneers "Sovereign Settlement Pipelines," delivering the autom

SettleFlow

FinTech

SettleFlow is a next-generation B2B payment and escrow platform powered by Dodo Payments, built to solve delayed payments and trust issues in freelance and business transactions. It enables businesses to create live shareable invoices with real-time funding and payment tracking, secure escrow-based settlements, and transparent release workflows between buyers and sellers.

SettleProof by AAP

Payments & Remittance

SettleProof is a Solana-native settlement layer for autonomous commerce. It implements AAP, the Agent Attestation Protocol, a protocol spec we created for cryptographic merchant attestation, smart contract custody, and automatic refunds. SettleProof holds USDC until a merchant signs proof of delivery; valid proof releases funds, while missing proof before TTL triggers auto-refund. AAP and SettleProof were designed together: AAP is the protocol spec, and SettleProof is the first reference.

Settlin

Interoperability & Bridges

Settlin is the execution governance and settlement layer for digital asset movement and is Solana-first. We sit independently between protocols and the chain, verifying high-risk transfers and admin actions against policy, refusing what shouldn't execute, and proving every decision with a ZK-backed receipt. The DeFi ecosystem has lost over $2bn to attacks with valid signatures in two years. Multisigs verify who signed. Settlin verifies whether the action should execute.

Settlix

Payments & Remittance

Settlix is a non-custodial Solana payment platform. Generate a payment link — anyone can pay you with any token they hold, and you always receive USDC. Jupiter handles the swap atomically on-chain, settling wallet-to-wallet in under a second. Works for merchants, freelancers, or anyone requesting funds. No custodian, no payout delays, no account freezes. Includes real-time payment notifications, transaction history, and QR codes with native Solana Pay support.

SetuX

Real World Assets (RWA)

SetuX lets Nepali exporters tokenize trade invoices on Solana using Tether QVAC AI running fully offline. OCR reads scanned Nepali documents, local LLM verifies against Nepal customs law, and the proof is minted as a Token-2022 asset with KYC enforcement via Anchor TransferHook. Exporters get 85% of invoice value instantly instead of waiting 90 days.

Shack

Consumer Apps

Shack: consumer to consumer trade network. Goal: becoming the global default for humans to trade possessions between each other | mitigating waste at scale.

ShadeOps

AI Platforms / Agents

ShadeOps is an agentic private payout operator for Solana teams. It turns payout intent into a policy-checked execution plan, recommends the right private payment mode, asks the admin to approve/sign, and generates a proof package after execution.

Shadow

DeFi

shadowperp is a private perpetual futures dex on solana. your trade size, leverage, entry price and liquidation price are all encrypted on chain so no one can see your positions. the math runs privately through multi party computation and only the final settlement result is published on chain. built for traders who want real privacy without giving up the speed of solana.

ShadowDao

Governance & DAOs

ShadowDAO is a privacy-first DAO governance and treasury app on Solana. It lets organizations create and approve proposals publicly, then execute treasury actions privately through Umbra, with built-in policy controls, audit trails, and emergency safeguards for production-ready operations.

shadownet

Identity & Privacy

ShadowNet is an on-chain ZK receipt and verification protocol built natively on Solana. Any application can issue tamper-proof receipts as on-chain PDAs and verify their integrity using zero-knowledge proofs without exposing the underlying data. Users connect via Phantom or Backpack, issue signed receipts to any Solana address, and verifiers can cryptographically confirm authenticity on-chain in a single transaction, fast, cheap, and composable with any Solana dApp. Currently live on devnet.

Shadowpay

Payments & Remittance

ShadowPay is a crypto payment platform that: Keeps your balance, identity, and transaction history private Uses zero-knowledge proofs to verify transactions without exposing any data Removes the need for traditional wallets — no public addresses, no exposure

Shadow Pay

DeFi

Every time you share your crypto wallet address, you hand over your financial identity. Anyone can search it on-chain and see your full history — who paid you, who you paid, how much, and when. That is not how money should work. ShadowPay fixes it. ShadowPay is a private payment link tool built on Solana Mainnet. Instead of sharing a wallet address, you share a link. The person on the other end clicks it, claims the funds, and neither side ever exposes their real wallet to the other.

ShadowPilot

Hardware & Devices

ShadowPilot is a private physical AI and robotic ops platform built for teleoperation and collection of humanoid data. Buyers create tasks with SOL bounties attached to them, pilots can take on tasks, complete them, get paid and have their reputation score adjusted accordingly. Arcium and WorldID integrations ensure privacy for pilots while also allowing buyers to create real-human-only tasks for maximum security and confidence in the data quality.

ShadowPool — The Cryptographic Dark Pool

DeFi

ShadowPool is an institutional-grade decentralized Dark Pool that enables zero-MEV trading of native assets across blockchains. It uses Encrypt's Fully Homomorphic Encryption (FHE) to completely hide order book sizes and prices, making front-running impossible. When an encrypted match is found on Solana, ShadowPool utilizes the Ika dWallet MPC network to generate a native Secp256k1 signature, settling the trade directly on the Bitcoin network without the use of wrapped tokens or vulnerable brid

Shard

AI Platforms / Agents

Algorithmic memecoin strategies, on-chain. Curators (humans or LLMs) design the rules; a deterministic Rust bot trades them on PumpSwap; depositors get fungible vault shares; authors and curators earn from every harvest. The autonomous-strategy vault primitive for markets existing DeFi infrastructure won't touch - memecoins today, perps and majors next.

Shard-Lock

DePIN

Shard-Lock (Seeker-Swarm) is a Decentralized Physical Infrastructure Network (DePIN) built exclusively for the Solana Seeker mobile device. At a high level, it transforms the Seeker phone into an unruggable, active storage node to serve as a distributed data availability layer for the 2026 Mobile AI and Robotics ecosystems. ***Pivot to VASS data resilience and survivability

ShareApp

FinTech

ShareApp is a social platform that enables people to organize events and manage shared funds through smart contracts powered by Solana. Our thesis is that crypto adoption will happen when it becomes part of everyday social interactions, not just financial speculation. By enabling programmable group funds and automated event contributions, ShareApp makes it easy to create digital “group wallets” (caixinhas), manage collective expenses, and ensure transparent and secure transactions.(Using Solana)

Sharkblock

DeFi

Sharkblock is a non-custodial AI-powered automated trading platform built on Solana. Its core feature: the shadow wallet, which lets traders test their strategies through simulated paper trading before deploying real capital. The platform offers 400+ configurable parameters (entries, exits, risk management, rug detection) and natively integrates with Claude via MCP — enabling users to build and control strategies in plain natural language.

shield

Data & Analytics

Shield is a Chrome extension that overlays real-time rug pull scores on every Solana token across the web powered by x402 micropayments at $0.01 per scan. Think of it as an ad-blocker for rug pulls, install once, and every token you encounter is automatically scored.

Shield

ZK / Crypto Research

Shield is a zkKYC layer for Solana. Businesses generate and publish a ZK proof of their user's identity attributes - age, jurisdiction, accreditation - verified on-device, never leaked. Apps like SurfCash let users pay through non-custodial wallets but still need to enforce limits like "user is 18+." Shield gives them a proof that's verifiable by anyone on-chain, without the document, without the database, without the breach risk.
