Crypto needs defense in-depth, not DIY
Our decentralized custody network is designed to remove all kinds of human intermediation that put crypto at risk. Leveraging cutting-edge cryptography and networking, our system disperses the single point of failure of the wallet and minimizes conflicts of interest to absurdly low odds.
No need to save what doesn't exist.
Multi-party computation or MPC — combined with zero-knowledge proofs, proactive secret sharing and other primitives — enables systemic keylessness. Instead of generating the key, our peer-to-peer network issues secret shares that can sign transactions as one while ensuring that they remain segregated throughout the entire wallet lifecycle.
We make the key disappear, voila!
By distributing the key generation among a network of independent signers (fully redundant, fault-tolerant Tier 3+/4 data centers) and harnessing built-in recovery capabilities provided by threshold signature, we offer full asset control and business continuity without offloading the responsibility of securing the keys like non-custodial solutions do.
Never trust, always verify.
Every user, employee, device, application, workload, and data flow is treated as untrustable, both inside and outside Dfns' zero trust network. We continuously authenticate, authorize and validate before anything or anyone gets access to our systems, which allowing us to outstrip adversarial moves and outmaneuver bad actors.
1 new blockchain every 2 weeks, 1 new token every 4 hours.

“On top of using one of the safest technologies, Dfns is providing one of the easiest custody systems to integrate. The team has been super reactive in integrating our feedback and provided pragmatic solutions to our problems.”
“Dfns’ bank-grade custody infrastructure shows a dedication to security that sits at the heart of Polymesh’s own core values as an institutional-grade blockchain for regulated assets. It’s our pleasure to collaborate with Dfns to bring issuers and investors on Polymesh extra peace of mind.”
“We believe that securing private keys, and therefore custody of digital assets, is a strategic capability for the future of Financial Institutions. Having worked closely with Dfns and their team since their participation in the ABN AMRO X Techstars accelerator we are excited to be part of their future as well.”
