Dfns

Dfns is a core banking platform built specifically for digital assets, designed to give banks, fintechs, and enterprises the infrastructure they need to operate onchain the way traditional core banking systems underpin conventional finance. Rather than replacing existing systems, Dfns provides the critical connecting layer that enables organizations to provision wallets, manage cryptographic keys, govern transactions, and service tokenized assets across more than 100 blockchains — all through a single REST API and SDK. The platform is organized into composable modules covering Wallet-as-a-Service, Transaction Management, Treasury Management, Tokenization, Policy and Governance Engines, and Key Management, with key security models spanning MPC, HSM, TEE, and bring-your-own-key configurations that ensure a complete private key is never assembled in one place. Dfns is best suited for regulated financial institutions, digital asset custodians, fintech builders, trading operations, and treasury teams that need programmable control over who can move assets, under what conditions, while meeting compliance requirements under frameworks like MiCAR and DORA. Over 400 institutional clients — including Standard Chartered, First Abu Dhabi Bank, Stripe, Circle, and Kraken — rely on Dfns for use cases spanning digital asset custody, embedded wallets, stablecoin payments, tokenization, and operational treasury management. The platform can be deployed as managed SaaS, hybrid, or fully on-premises, giving organizations the flexibility to place key material and infrastructure according to their specific regulatory and operational requirements.
