Dynamic

Dynamic is a developer-first wallet infrastructure platform that packages authentication, embedded wallets, wallet connections, and key management into a single SDK. Its premise is simple but ambitious: rather than forcing every application team to negotiate separate integrations for sign-in flows, wallet generation, multi-chain transactions, and compliance controls, Dynamic exposes all of those capabilities through one unified interface — covering everything from low-level cryptographic primitives to fully prebuilt onboarding flows that ship in days.

Founding and Early Backing

Dynamic was founded in December 2021 by Itai Turbahn and Yoni Goldberg, two MIT graduates and long-time friends who previously served in Israeli military intelligence. Turbahn serves as CEO; Goldberg as CTO. The pair's shared background in infrastructure and security shaped the product's early emphasis on developer experience and enterprise-grade key management.

The company attracted institutional backing quickly. Andreessen Horowitz (a16z) led a $7.5 million seed round in 2022, and in December 2023 Dynamic announced a $13.5 million Series A co-led by a16z crypto and Founders Fund, with additional participation from Castle Island Ventures, Breyer Capital, and Alchemy co-founders Nikil Viswanathan and Joe Lau. Total pre-acquisition funding reached roughly $21 million.

What the SDK Does

Dynamic's core product is a JavaScript-native SDK that handles the full lifecycle of user wallet interactions. Developers integrating Dynamic gain immediate access to several capabilities:

Embedded wallets are non-custodial wallets that Dynamic generates and manages on behalf of users within an application's own interface. The user never needs to install MetaMask or Phantom — the wallet appears seamlessly during signup. Dynamic uses Threshold Signature Scheme Multi-Party Computation (TSS-MPC) to distribute private key shares across multiple parties, so a complete private key never exists in one place. This approach delivers sub-second signing while preserving non-custodial guarantees and allowing wallet recovery even if Dynamic's own infrastructure goes offline.

External wallet connections give applications pass-through access to more than 800 existing self-custody wallets through the same integration. An app built on Dynamic can let users bring their own Phantom, Backpack, or Ledger wallet without the developer writing chain-specific connector code.

Authentication flows span the full spectrum from wallet-native (sign-in with wallet) to social login (Google, Apple, Farcaster), email, SMS, and phone — serving both crypto-native audiences and users who have never held a digital asset. SDK V2 added SMS login for embedded wallets alongside Wagmi V2 and Viem V2 support, making it easier to build mobile-first entry points.

Enterprise self-custody extends this infrastructure to institutional clients through distributed signing with configurable thresholds, spending limits, allowlists, rate-limiting, MFA, and OFAC screening — controls normally reserved for purpose-built custody vendors.

Solana Support

Dynamic explicitly includes Solana within its multi-chain coverage alongside EVM chains, Bitcoin, Sui, and Cosmos. Developers building Solana applications can generate and manage embedded wallets for users, sign Solana transactions through the unified SDK, and take advantage of gasless transaction sponsorship — Dynamic lets applications cover network fees on behalf of users so they can interact with a Solana app without needing to hold SOL. This frictionless path is particularly relevant to DeFi onboarding, gaming, and consumer applications where expecting a new user to acquire native tokens before they can take their first action creates abandonment.

SDK V3 included specific optimizations for Solana embedded wallet transactions, and multi-chain wallet creation covering EVM and Solana simultaneously is supported within Telegram mini apps — a distribution channel that has grown substantially for Solana-native consumer products.

Customers and Scale

By the time of its acquisition in October 2025, Dynamic reported more than 50 million users onboarded across its client base, 2,400 enterprise clients, and 99.9% platform uptime. Named deployments span institutional and retail:

• Kraken uses Dynamic for its Inky consumer platform
• Magic Eden, the cross-chain NFT marketplace with strong Solana roots, integrated Dynamic for wallet and onboarding flows
• Ondo Finance, a tokenized US Treasury issuer, uses Dynamic for user authentication
• zerohash and Lighter.xyz are also named as production deployments
• Enterprise names including Western Union, Circle, Stripe, and Franklin Templeton are cited in marketing material as clients or partners

Fireblocks Acquisition

On October 23, 2025, Fireblocks — the institutional digital asset custody and settlement network — announced it had acquired Dynamic. Reports placed the deal value at approximately $90 million. Dynamic's 30-person team joined Fireblocks as part of the transaction.

The strategic logic Fireblocks articulated was the creation of a "custody-to-consumer stack": Fireblocks already served banks, exchanges, and payment processors with its institutional key management and settlement rails, but lacked consumer-facing onboarding and embedded wallet tooling. Dynamic supplied exactly that. Dynamic CEO Itai Turbahn framed it as accelerating the path to onchain financial services for fintechs and enterprises that do not have dedicated crypto engineering teams.

Post-acquisition, Dynamic continues to operate under its own brand at dynamic.xyz, with the same products and SDK interface. The blog now publishes under the Fireblocks umbrella, and the team has been promoting joint products including Fireblocks Flow — stablecoin payment infrastructure that layers onto the embedded wallet stack Dynamic provides.

Current State

As of mid-2026, Dynamic remains an active, shipping product. The X account posts regularly about developer use cases, hackathon involvement, and the agent wallet category — Dynamic's team has noted that AI agents increasingly need embedded wallets to execute onchain payments autonomously, citing examples from the Startup School Hackathon where agent teams built on Dynamic to give their bots the ability to transact. This positions Dynamic at the intersection of two growing Solana narratives: embedded consumer wallets for mainstream onboarding and autonomous agent infrastructure.

Developers can access Dynamic through a free tier supporting up to 1,000 monthly active users, with paid plans scaling for production deployments. The documentation has migrated to dynamic.xyz/docs and covers SDKs across JavaScript, React, React Native, Swift, Flutter, Unity, Kotlin, Python, Rust, and Java.
