An x402 component marketplace built for crypto-native builders and technical users.

Access premium on-chain tools and receive structured professional output, exportable in any format. No accounts, no subscriptions, no friction.

Live on Solana mainnet. Pay with USDC or $MODU. Permanent report storage.

Modulr is a live, functioning on-chain marketplace for crypto infrastructure tools. Users connect a Solana wallet, pay in USDC or $MODU, and receive immediate access to professional-grade reports and analytics generated instantly in-browser and permanently saved to their dashboard.

Every tool on Modulr is pay-per-use. One payment unlocks one generation. Reports are saved to the connected wallet dashboard and re-downloadable at any time in any of five formats: PDF, HTML, MD, TXT or JSON.

No accounts. No subscriptions. No data sent to a server during tool use.

Five tools are live on Modulr today.

Fetches up to 1,000 on-chain transactions via Helius RPC and computes a heuristic risk score across five dimensions: wallet age, activity level, token diversity, balance consistency and dormancy. Each dimension includes a confidence label based on available data quality.

Outputs a full report with risk score, wallet type classification (Bot, Whale, DeFi Trader, NFT Collector, Pump.fun Trader and more), detected protocols (Jupiter, Raydium, Orca, Magic Eden, pump.fun, Meteora and more), NFT holdings count via Helius DAS, funding source from oldest transaction, 12-month activity timeline, counterparty analysis with pattern detection and a plain-English analysis verdict. Exportable in PDF, HTML, MD, TXT or JSON.

Takes structured project inputs and produces a readiness score with section-level analysis, risk flags and recommended next steps. Paste a Solana mint address to trigger on-chain verification via Helius — fetches mint authority, freeze authority, supply, decimals and liquidity pool status directly from chain, then flags discrepancies between what you claimed and what the chain actually shows.

Outputs a launch verdict paragraph with go/no-go assessment, section blockers with Critical, High and Medium impact labels, risk flags and recommended next steps. Works without a mint address for non-Solana or pre-deploy projects.

Scans pasted Solidity, Rust/Anchor or Move code against 30+ vulnerability patterns across Critical, High, Medium, Low and Informational severity levels. Includes a dedicated gas optimisation section with 8 patterns covering storage loops, redundant writes and type inefficiencies.

Outputs a security risk score, a separate code quality score (0–100) measuring documentation, standards usage and validation patterns, severity-ranked findings, a gas optimisation section, a security checklist, suggested fixes, positive signals and an executive summary with a plain-English deploy recommendation: Deploy, Deploy with caution, Address findings first or Do not deploy.

Generates a complete, production-ready token launch website from project details. AI-powered, fully responsive, single HTML file with inline CSS, animations and a copy-CA button. Four style vibes: minimal, aggressive, professional or neon. Supports logo upload and community link detection for Twitter, Telegram and Discord.

Describe the agent you want and get a complete, production-ready TypeScript script back. Specify the agent type, target chain, trigger conditions, parameters and framework — Modulr generates a complete, runnable agent with setup instructions, required environment variables and a dependencies list. Download as a ZIP.

8 agent types: Trading Bot, Wallet Monitor, Price Alert, DeFi Automation, NFT Sniper, Portfolio Tracker, Liquidity Manager and Custom. Supports Solana, Ethereum, Base and Arbitrum. Frameworks: Vanilla TypeScript, Anchor, Ethers.js and Viem.

The creator marketplace at modulr402.com/marketplace is an open listing of x402-payable tools built by external developers. Any developer can submit a tool, have it reviewed and earn USDC per call from day one.

1. Build an x402-compatible API endpoint
2. Submit at modulr402.com/marketplace/submit — pay a $10 USDC listing fee
3. Modulr verifies the endpoint live, checks quality flags and confirms the fee on-chain
4. Approved tools go live at their own URL with TypeScript and cURL snippets generated automatically
5. Callers pay in USDC via x402 directly to the creator — Modulr takes no cut per call

The listing fee is refundable if the tool is not approved and listed.

Seven x402-payable tools built by Modulr are live in the marketplace:

All backed by live Helius data and AI-powered analysis. Each official tool carries a verified badge on the marketplace.

• Search by tool name, tag or creator
• Filter by category: Security / Analytics / Automation / Data / Development

The Modulr SDK is live. Developers can install it with a single command and call Modulr tools programmatically — no API key, no setup, no browser required.

npm install @modulr/sdk

import { Modulr } from '@modulr/sdk'

const modulr = new Modulr()

const risk = await modulr.walletRisk.analyze('9apA5U8...')
const agent = await modulr.agent.generate({ agentName: 'Whale Tracker', agentType: 'Wallet Monitor', ... })

Modulr is live infrastructure in active development. The tools available today use heuristic analysis. They are not replacements for professional audits, legal advice or financial due diligence. All reports carry explicit disclaimers and should be used as a starting point for further review, not a final verdict.

$MODU is a utility token, not a financial instrument or investment. Token value is not guaranteed and depends on platform adoption, market conditions and continued development.
