Dynamic is a Web3 wallet infrastructure platform that provides embedded wallets, authentication tools, and multichain connectivity for digital applications. The service enables developers to combine familiar login methods with blockchain accounts, allowing users to access crypto products without installing browser extensions. Dynamic supports embedded, external, server, and cross-application wallets through a unified development stack. Following its acquisition by Fireblocks in 2025, the platform continued operating as an infrastructure layer for fintech companies, crypto applications, and enterprise solutions.

1. Dynamic: Web3 Wallet Infrastructure
Dynamic is a developer platform designed to integrate wallet creation, authentication, and blockchain transactions into websites and applications. Instead of requiring every user to install MetaMask, Phantom, or another external wallet, products can automatically create an embedded blockchain account during registration.
Users can log in using familiar methods such as email, phone number, or social accounts. The wallet is generated in the background and linked to the user profile, hiding much of the technical complexity associated with private keys, network switching, and wallet connections.
This model is particularly relevant for consumer applications, fintech products, games, marketplaces, and payment services. In these sectors, requiring users to understand seed phrases and browser extensions before accessing the core product can significantly reduce conversion rates.
Dynamic is not a standalone blockchain or a consumer crypto wallet. It is an infrastructure solution that other companies use to build their own wallet interfaces, authentication flows, and blockchain experiences.
2. How Embedded Wallets and Key Management Work
Dynamic's embedded wallets are created directly within an application and are designed to keep users in control of their assets. According to the platform architecture, no single party should possess the complete private key. Distributed signing technologies enable transaction authorization without storing the entire key in one location.
The platform supports MPC wallets, where cryptographic key shares are distributed across protected components. During transaction signing, the participants cooperate without reconstructing or exposing the full private key.
Dynamic supports embedded wallets across EVM-compatible networks, Solana ecosystems, Sui, and Bitcoin. When multiple networks are enabled, applications can create separate addresses for different blockchain families while maintaining a unified account experience.
Developers can also configure account recovery methods and authentication requirements. These features improve usability, but they must be carefully designed because compromised email accounts, social logins, or recovery factors can become attack vectors even when the underlying cryptography remains secure.
3. Comparing Dynamic with Traditional Wallet Solutions
Dynamic combines the functionality of a wallet SDK, authentication service, and account management platform. Unlike a traditional browser wallet, it is integrated into a third-party product and can be customized to match the application's interface and business logic.
The platform also differs from centralized exchange accounts. Crypto exchanges typically control user funds through their own custody infrastructure, whereas embedded wallet providers aim to deliver a familiar login experience without granting applications unrestricted control over user assets.
| Solution | Wallet Creation | Key Management | Primary Use Case |
|---|---|---|---|
| Browser Wallet | Created independently by the user | Seed phrase or local account | Access to independent dApps |
| Centralized Exchange | Created within an exchange account | Controlled by the exchange | Trading and custodial storage |
| WalletConnect | Uses an existing external wallet | Managed by the connected wallet | Connecting wallets to dApps |
| Basic Embedded Wallet | Created automatically within an app | Depends on provider architecture | Simplified Web3 onboarding |
| Dynamic | Created via SDK or API | Distributed signing and configurable architecture | Embedded, external, global, and server wallets |
Dynamic's main advantage is flexibility. Developers can onboard new users through embedded wallets while continuing to support experienced users who prefer external wallet solutions. This prevents businesses from forcing every customer into a single account model.
The primary limitation is reliance on third-party infrastructure. If authentication, signing, or wallet APIs become unavailable, applications may lose part of their functionality. Developers should therefore evaluate wallet export options, recovery procedures, and contingency plans in advance.
4. Core Products and Use Cases
Dynamic offers several wallet types for different operational models. Embedded wallets are designed for mass onboarding, while support for external wallets allows users to connect existing accounts. Server wallets are intended for backend systems, automated services, and AI agents that need to initiate blockchain transactions programmatically.
Global wallets extend the embedded wallet concept beyond a single application. Depending on implementation, users may connect the same wallet across partner products and services instead of creating separate accounts for every platform.
- Embedded wallets with email, phone, and social authentication.
- Support for external wallets and multiple connected accounts.
- Wallet infrastructure for EVM, Solana, Sui, and Bitcoin ecosystems.
- Server wallets for backend services and automated transactions.
- Global wallets for cross-application access.
- Support for smart wallets and gas sponsorship.
- Delegated permissions for AI agents and recurring operations.
- Integration with external wallets and fiat payment providers.
Delegated access allows users to authorize applications to perform limited actions on their behalf. This can be useful for trading bots, recurring payments, automated workflows, and gaming mechanics. Such permissions should always be restricted by transaction type, time period, assets, and spending limits.
Server wallets serve a different purpose because they are controlled through backend logic rather than direct user approval. They can support treasury management, automated payouts, protocol services, and AI agents, but they require strict API security, monitoring, and transaction controls.
5. Security, Fireblocks Integration, and the Future of Dynamic
Security is a critical aspect of wallet infrastructure because the platform sits between users, applications, and blockchains. Potential risks include account takeovers, abuse of delegated permissions, compromised developer credentials, frontend substitution attacks, and transaction policy misconfigurations.
In October 2025, Fireblocks announced its acquisition of Dynamic. The deal combined Dynamic's embedded wallet and authentication technologies with Fireblocks' institutional infrastructure for custody, payments, and digital asset operations. Existing Dynamic products and integrations continued to be supported after the acquisition.
This combination may help financial institutions connect enterprise-grade digital asset infrastructure with consumer-facing wallets. Businesses can manage treasury and settlement operations through a corporate platform while simultaneously providing customers with embedded Web3 accounts.
However, integration with a larger infrastructure provider does not eliminate technical or operational risks. Developers must still evaluate key management architecture, recovery mechanisms, supported networks, delegated permissions, and the level of control retained by end users.
Dynamic reflects the broader transition from standalone crypto wallets to integrated account infrastructure. Users increasingly interact with blockchain technology through games, financial applications, social platforms, and payment services rather than dedicated wallet interfaces. Dynamic's long-term significance will depend on its ability to combine seamless onboarding, multichain support, strong security, and user control within a single development platform.
