Crypto custody as an API.

One simple line of code supercharges your app with a keyless wallet infrastructure providing security and freedom for crypto.

Ultrasafe Custody

Wallet Generation

Using multi-party computation and threshold signature, the key is generated in secret shares which brings the risk of theft or misuse close to zero. By decentralizing the wallet generation process, we mitigate the only risk vector that leads to IT and physical assault.

ZKP Ceremony

Flawless crypto custody can only be achieved through systemic keylessness. MPC combined with ZKP and TSS enable us to provide built-in recovery capabilities as we only need a subset of all the key shares to generate wallets and sign transactions. Dfns is currently based on a 3:7 honest majority and supports ECDSA, EdDSA, and Schnorr.

Transaction Signing

On top of ensuring full key share segregation throughout the entire wallet lifecycle, we also integrate dynamic cryptographic properties allowing us to refresh the key shares several times a day and execute signatures 24/7—high-speed and low cost.

We support 500+ assets

Crypto, STO, NFT, and more.

"On top of using one of the safest technologies, Dfns is providing one of the easiest custody systems to integrate. The team has beetn super reactive in integrating our feedback and provided pragmatic solutions to our problems"

Sébastien Krafft — CTO @Mt_Pelerin
