The company

Dfns is a cybersecurity company that builds custody* SaaS protocol for web3 apps. Think of it as a developer tool that provides secure cloud for crypto.

Our mission is to bring serenity to DeFi by eliminating new blockchain risks and vulnerabilities, and making crypto transactions easier, faster, more affordable, and compliant with exisiting regulations.

From fintechs to large banks to e-commerce sites, Dfns gives platforms the freedom to manage and transfer crypto on a battle-designed security infrastructure. Our API is designed to offer best-in-class developer experience and allows any app to deploy custodial wallets in a matter of days, with streamlined feature delivery and security upgrades.

At the core of our infra runs a keyless wallet generation process (zk protocol) enabling clients to send, deposit, and store any digital asset (crypto, STO, NFT, etc.) with peace of mind. Dfns is powered by a decentralized custody network designed to break up the inner complications of blockchains, remove all single points of failure, and reinstate frictionless business environments.

Today, more than 100 companies such as Paxos, Bitgo, Kraken, Coinbase, ConsenSys, Galaxy, Blockfi, Metamask, Figment, Fidelity, and JP Morgan have registered on our waitlist to try out our solutions.

Founded in 2020 in Paris, Dfns is a startup incubated at Station F (awarded Future 40), backed by Techstars and recognized DeepTech by the French Ministry of Economy. Our company is fully remote with offices in Paris, Amsterdam, New York, London, Stockholm, Sofia, and other cities.
