About the Team

Dynamic, part of Fireblocks, represents the next evolution of non-custodial wallet infrastructure. Dynamic is an embedded wallet platform purpose-built for developers who want to bring crypto and stablecoin experiences into modern applications without complexity.

Dynamic was founded in 2021 with the vision that every app and website will have a wallet component.

Dynamic powers wallet-based experiences for leading crypto and fintech teams including Kraken, zerohash, and Magic Eden.

The Dynamic team builds and maintains developer-first SDKs that enable teams to seamlessly integrate embedded wallet functionality directly into their applications. The team has onboarded 50M+ wallets across crypto and fintech applications. Engineers at Dynamic build secure-by-default systems with a strong customer focus, balancing technical excellence with real-world user needs.
