ShieldPay

Payments & Remittance

ShieldPay helps merchants prevent fraud and chargebacks by requiring users to prove their identity and explicitly sign sensitive actions. We verify this off-chain and anchor the result on Solana as tamper-proof evidence, without storing personal data.

SHIELD-PAY

Payments & Remittance

Programmable trust infrastructure for the service economy. ShieldPay locks USDC in on-chain escrow vaults (PDAs) until milestones are delivered and approved. If the client goes silent, a permissionless auto-release crank transfers funds to the service provider — no server, no cron, no middleman. Every user earns a portable on-chain trust score based on real payment and delivery behavior, readable by any platform. 149 teams attempted this in past hackathons. None won. None shipped. We shipped.

Shield Trade

Security Tools

Shield Trade is the pre-transaction security layer for Solana, protecting users before irreversible damage occurs. It intercepts transactions before signing, simulates execution to detect threats, and enforces protection via Secure RPC at the network level. Unlike reactive tools, Shield Trade prevents attacks in real time, closing the critical gap in Web3 security and enabling safe adoption of DeFi, RWA, and stablecoin applications.

shingo

Consumer Apps

Twitter for encrypted trading signals. We are putting an end to Telegram VIP trading groups. Copy trading is one of the biggest market of the trading ecosystem. Traders have to proof their performances to attract followers. So we are here, we are the place where traders and followers meet, trustless, because track record is public onchain, and live signals are private and accessible for subscribers only until they expire. Choose your traders, follow them, start to copying trades.

ship

Developer Infrastructure

Building dApps on Solana takes weeks even for experienced devs. Ship turns plain English into a deployed Solana Mobile dApp in minutes — describe an idea, an AI agent scaffolds, codes, tests, and ships it with wallet-gated auth (SIWS), MWA integration, and on-chain payments built in. The first prompt-to-dApp tool native to Solana Mobile. Built so the next million builders don't need to learn Anchor — they just need to know what they want to ship.

ShipChain

Supply Chain & Logistics

Global Trade Settlement Engine Based on Solana(基于 Solana 的全球贸易结算引擎) The global trade settlement engine based on Solana relies on smart contract and oracle technologies to achieve traceable transaction trust and instant fund settlement, greatly improving the efficiency of trade settlement, reducing cross-border transaction costs, and adapting to the needs of global trade scenarios.(基于 Solana 的全球贸易结算引擎,依托智能合约与预言机技术,实现交易信任可追溯、资金即时分账��大幅提升贸易结算效率,降低跨境交易成本,适配全球贸易场景需求。)

ShipDapp

AI Platforms / Agents

ShipDapp is a decentralized Platform-as-a-Service (PaaS) that transforms natural language prompts into live, self-sustaining applications on the decentralized cloud. Designed for the "vibecoding" era, ShipDapp removes the technical and financial friction of deployment, allowing creators to ship unbannable, community-funded software in minutes.

ShiroTerminal

DeFi

I watched too many people walk away from crypto because no one made it simple. Because the tools made it impossible. So I built ShiroTerminal . Every token tells you what happened and why. Every move has a reason behind it. Every risk is flagged before you're in. You don't need to decode charts anymore. You just need to show up. The rest is already explained. For the beginner who needs a guide. For the veteran who just wants clarity. ShiroTerminal is for everyone

Shopier

Consumer Apps

Shopier shops fashion for you on Solana. Drop a screenshot or set a watch on a celebrity; the agent identifies the look, prices each piece across retailers, and settles in USDC inside spending limits you signed once. Session keys let it act in 30 seconds without re-prompting your wallet. WatchPolicy caps which celebrities, which sections, which budgets. Lagos shoppers settle USDC, merchants receive Naira through the Raenest adapter.

Shredr

Identity & Privacy

Shredr is a Privacy tool for defi users, small scale businesses and freelances to recieve private payments without revealing their main wallet to the sender. This protects the user's privacy and prevents wallet tracking and "doxxing" by curious third parties or malicious actors.

Shyft

Social / SocialFi

Shyft is a fully on-chain social media platform built on Solana. Every post, comment, like, follow, and reaction is stored directly on the blockchain — no centralized databases. Features include encrypted DMs (E2E via X25519), paid/private posts with SOL tipping, @mentions with notifications, profile hover cards, image/video uploads via IPFS, token launches with bonding curves, real-time feed updates, communities, and Shyft AI — a built-in AI assistant accessible from your feed.

Shypt

Consumer Apps

Shypt is privacy-first physical commerce on Solana. Every shipping address is sealed client-side with X25519 NaCl box + AES-256-GCM, wrapped to the public key of the fulfillment partner only. Sellers see an order. The platform sees ciphertext. Just the verified shipper can open the envelope. Combined with burn-to-claim and direct SOL/USDC/SPL sales, Shypt lets any token launch a real storefront where buyers can confidently put a real address behind a pseudonymous wallet.

Sigil

AI Platforms / Agents

AI agents can now transact and act autonomously — but there's no infrastructure to prove who an agent is, what it's authorized to do, or who's liable it goes wrong. Sigil fixes that. It issues on-chain credentials to AI agents on Solana: cryptographically to a keypair, encoding capability scopes, spend limits, posted collateral, and expiry. Any service can verify a Sigil before executing. No trust assumptions. Full accountability.

SigIntZero

Security Tools

SigIntZero is a security-focused research and development firm building real-time on-chain monitoring and defence systems for blockchain protocols. Our product, Tripwire, is a 24/7 threat detection and response system that identifies exploit signals before execution, monitoring contract behaviour, fund flows, and attack patterns to protect deployed protocols in production.

Signal

Consumer Apps

Signal is a sybil-resistant verification layer on Solana that converts ephemeral event attendance into permanent on-chain capital. By wrapping physical events with verifiable check-ins, it replaces easily faked resumes with an immutable Builder Passport.

Signal402

AI Platforms / Agents

AI-verified prediction market signals. Global. Trustless. On-chain.

SignalCred

Data & Analytics

SignalCred is the trust and reputation layer for Bags tokens. Every Bags launch becomes a verifiable asset profile — source proof, pool proof, creator/admin proof, fee loop evidence, claim receipts, token-linked social proof, and USDT-denominated creator economics. For the Tether track, QVAC runs a private, on-device AI trust review that reads the real evidence locally and explains what to inspect before trading — no cloud, no API keys, never invents proof.

Signal Protocol

DePIN

Signal Bot is a DePIN oracle network on Solana that pays everyday people USDC to report real-world prices via Telegram. Snap a photo of a fuel pump, grocery shelf, or electricity bill — Vision AI verifies it instantly. Verified data is aggregated on-chain into tamper-resistant oracle feeds that AI agents and enterprises subscribe to via Jupiter. No hardware, no wallets, no friction. Just Telegram.

SIK — Solana Identity Kit

Developer Infrastructure

The identity primitive for humans and agents on Solana. One SDK call returns a .sol profile, an on-chain reputation score, and verifiable credentials for any user — or an operator, trust score, and capability set for any AI agent. Any protocol can gate access, verify trust, and authenticate users without building identity logic from scratch.

Silicon Colesium

AI Platforms / Agents

An AI trading app where AI agents created with personalities of famous celebrities trade for tokens based on prices of commodities like gold, silver, wheat, curde oil etc. Users can spectate and bet on agents using either the currency of the platform or SOL. Currently the projects is deployed on Solana devnet.

Silkguard

Payments & Remittance

SilkGuard is an enterprise-grade AI compliance oracle and settlement gateway for Solana. It secures crypto-to-fiat off-ramps (e.g. S1lkPay) by routing funds through a PDA Vault while a Neural Engine performs real-time AML heuristics and OFAC checks. Clean transactions are instantly settled with cNFT receipts minted via Helius, while illicit funds are blocked and refunded. SilkGuard provides the missing regulatory layer needed to safely bridge Web3 liquidity with traditional banking.

Silo

AI Platforms / Agents

Silo is a 4-layer on-chain firewall protecting Solana AI agents from prompt injections and malicious trades. Before a transaction executes, Silo encrypts the intent, queues it via our Anchor program, and uses Claude AI to analyze the payload. Based on the calculated threat score, transactions are automatically APPROVED, BLOCKED, or ESCALATED to a human operator for review. Silo provides a tamper-proof reputation system and essential security for the future of autonomous on-chain agents.

SilphCoAnalytics

Data & Analytics

Verified on chain and off chain sales, graded population data, and historical market analytics for Pokemon TCG with agentic payment model for API access.

SIMD

DePIN

SIMD Agent is an AI-native physics simulation copilot that uses Solana for decentralized compute coordination and settlement, turning engineering intent into validated simulations executed across distributed GPU infrastructure worldwide

Simpletext

Consumer Apps

SimpleChat. Better than Notepad. Solana enabled.

Simplybots

Consumer Apps

A telegram bot project similar to major buy bot or cherrytgbot with the main difference that I am supporting specifically the telegram in groups "TOPIC" section which the other bots do not support. Specifically developed for solana & Pumpfun but generally compatible with Solana on all DEXs

Simulacra

Developer Infrastructure

Simulacra lets protocols, researchers, LPs, and traders fork real Solana mainnet state, simulate behavior under realistic market conditions, and test decisions before risking millions in production. Instead of relying on intuition, spreadsheets, or incomplete backtests, teams can test liquidity behavior, execution dynamics, incentives, and protocol changes against realistic market conditions before deploying them live.

Sim Wars

AI Platforms / Agents

Bad tokenomics kills more crypto projects than bad code. SimWars deploys a swarm of LLM-driven adversarial agents (whales, governance attackers, MEV bots, sybil rings, treasuries, and many more personalities) against your token economy on Solana, then ships a post-sim resilience report exposing death spirals, peg breaks, and governance capture. Upload a whitepaper PDF or pick a preset.

Sinergy

Payments & Remittance

Sinergy is a multi-corridor payout orchestration platform for businesses paying contractors and vendors in emerging markets. Companies fund in USDC on Solana, and Sinergy handles quoting, compliance, routing, and local fiat delivery across Colombia, Argentina, Mexico, India, and Nigeria, focusing on specific corridors where cross-border payouts are still slow, fragmented, and operationally painful

SingulAI AvatarPro Vault

AI Platforms / Agents

SingulAI AvatarPro Vault is a Solana-based platform for verifiable AI avatars. Users connect a wallet, create an AvatarPro, encrypt professional memories or time capsules off-chain, and register tamper-proof hashes and execution proofs on Solana.
