О компании и продукте

• Dynamic was founded in 2021 with a simple vision: every app and website will have a wallet component. That vision is rapidly becoming reality. Wallets are no longer limited to crypto-native products, they are becoming foundational infrastructure for payroll, remittances, and global payments. Dynamic powers wallet-based experiences for leading crypto and fintech teams including Kraken, zerohash, Magic Eden, and more.
• Dynamic builds and maintains developer-first SDKs that enable teams to seamlessly integrate embedded wallet functionality directly into their applications. These embedded wallets allow end users to create, manage, and use wallets without leaving the product experience, making wallets feel like a native part of modern fintech and crypto apps.
• The world of digital assets is accelerating in speed, magnitude, and complexity, opening the door to new ways for leveraging the blockchain. Fireblocks’ platform and network provide the simplest and most secure way for companies to work with digital assets and it trusted by some of the largest financial institutions, banks, globally-recognized brands, and Web3 companies in the world, including BNY Mellon, BNP Paribas, ANZ Bank, Revolut, and thousands more.
