Dynamic: A Multi-Chain Wallet-Based Authentication & Authorization Platform

·

In the rapidly evolving world of web3, user authentication remains a major bottleneck for developers. Traditional login systems don’t translate well to decentralized applications, and building secure, wallet-based access from scratch is time-consuming and complex. Enter Dynamic — a powerful, developer-first platform that simplifies wallet-based authentication across multiple blockchains.

Backed by a $7.5 million seed round led by a16z Crypto, Dynamic is emerging as a leading solution for teams looking to integrate seamless, secure, and scalable identity verification into their web3 applications. In this comprehensive guide, we’ll explore what Dynamic is, how it works, its core features, security protocols, and why it’s becoming essential infrastructure for modern decentralized apps.

What Is Dynamic?

Dynamic is a multi-chain wallet-based authentication and authorization platform designed to help developers streamline user onboarding and identity management. With Dynamic, developers can implement secure, wallet-powered logins in under a minute — freeing them to focus on building core product features instead of reinventing identity infrastructure.

At its core, Dynamic abstracts the complexity of web3 authentication into a simple SDK and intuitive developer dashboard. Whether you're launching an NFT-gated community, a DeFi protocol, or a blockchain-based social network, Dynamic provides the tools to authenticate users seamlessly using their crypto wallets.

How Does Dynamic Work?

Dynamic simplifies the integration process into three key components: SDK, Developer Dashboard, and API.

1. Dynamic SDK

The Software Development Kit (SDK) is embedded directly into your application’s frontend. It automatically detects installed wallets (like MetaMask, WalletConnect, Phantom, etc.), supports both desktop and mobile environments, and adapts to your site’s design language.

Once implemented, the SDK handles:

No backend setup is required — Dynamic manages everything behind the scenes.

2. Developer Dashboard

After integrating the SDK, developers gain access to a powerful control panel where they can:

This no-code interface empowers teams to iterate quickly without relying on engineering resources for every change.

3. Dynamic API

For deeper integrations, Dynamic offers a robust RESTful API that allows full control over user data and authentication flows. Developers can:

Together, these components make Dynamic a full-stack identity solution tailored for web3.

Core Features of Dynamic

Dynamic goes beyond basic wallet login. It provides a suite of tools that enhance security, usability, and access control.

🔐 Secure Wallet-Based Authentication

Using Ethereum’s Sign-In with Ethereum (SIWE) standard (EIP-4361), Dynamic ensures cryptographically secure authentication. Users sign a message to prove ownership of their wallet — private keys never leave the wallet.

🧩 Multi-Wallet & Multi-Chain Support

Dynamic supports all major wallets (MetaMask, Coinbase Wallet, Phantom, WalletConnect) across Ethereum, Polygon, Solana, Arbitrum, Optimism, and more — with continuous expansion to new chains and wallets based on community feedback.

🎯 NFT-Gated Access

Restrict access to your platform based on NFT ownership. Configure rules in the dashboard so only users holding specific NFTs can log in — perfect for exclusive communities, DAOs, or premium content platforms.

✅ Allowlists & Blocklists

Create private testnets or alpha releases using allowlists. Conversely, block malicious or ineligible addresses with one click. Ideal for early-stage dApps managing access during beta phases.

📝 Custom Onboarding Fields

Collect additional user information at login — such as email, Discord handle, or preferences — through customizable input fields. All data collection is optional and user-controlled.

🛡️ Risk-Based Wallet Screening (Optional)

Enhance compliance by enabling automatic screening against Chainalysis OFAC sanctions lists. This optional feature blocks high-risk wallets associated with illicit activity — helping projects meet regulatory expectations.

🎨 Fully Customizable UI

From button colors to modal animations, every visual element of the login flow can be tailored to match your brand. The SDK supports theme inheritance from your app’s CSS, ensuring a native feel.

🌐 User Management System

Dynamic doubles as a complete user management backend. View active sessions, track login history, export user data, and manage permissions — all from a single dashboard.

Security: Dynamic’s Top Priority

Security isn’t just a feature — it’s foundational to Dynamic’s architecture.

1. Built on Itself: Eating Our Own Dog Food

Dynamic uses its own platform for internal authentication. This means every new feature undergoes rigorous real-world testing before being released publicly.

2. Zero Access to Private Keys

Dynamic never accesses or stores users’ private keys. Authentication relies solely on digital signatures generated by the user’s wallet — aligning with decentralized security principles.

3. Industry-Standard Protocols

Dynamic adheres to:

4. SOC 2 Compliance & Bug Bounty Program

Dynamic is actively pursuing SOC 2 Type II certification, a gold standard for data security in enterprise software. Additionally, a public bug bounty program via HackerOne invites ethical hackers to identify vulnerabilities.

Advisors include veterans from Okta, Auth0, and Zenefits — leaders in traditional identity management.

5. End-to-End Encryption

All data in transit is protected via HTTPS/TLS. At rest, sensitive data is encrypted using AES-256, with critical keys managed through Key Management Services (KMS).

6. User-Controlled Data Storage

Developers decide what data to store. You can choose to retain only public wallet addresses — or collect additional info with user consent. Transparency and minimal data retention are core design principles.

Frequently Asked Questions (FAQ)

Q: Is Dynamic only for Ethereum-based apps?
A: No. Dynamic supports multiple blockchains including Ethereum, Polygon, Solana, Arbitrum, Optimism, and more — with ongoing expansion.

Q: Can I use Dynamic without storing any user data?
A: Absolutely. You can configure Dynamic to store only public wallet addresses or no data at all — giving you full control over data privacy.

Q: How does NFT-gated access work?
A: In the developer dashboard, you specify which NFT collection(s) grant access. When a user attempts to log in, Dynamic checks their wallet holdings in real time.

Q: Does Dynamic support social recovery or multi-sig wallets?
A: Yes. Since Dynamic works at the wallet abstraction level, it supports any wallet type that can sign messages — including smart contract wallets with social recovery features.

Q: Is there a cost to use Dynamic?
A: Dynamic offers a free tier for startups and developers. Enterprise plans with advanced features are available for scaling applications.
