Crypto custody as an API.
One simple line of code supercharges your app with a keyless wallet infrastructure providing security and freedom for crypto.
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.
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.
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.
One API to generate wallets at scale, manage configurable accounts and execute high-speed, low-cost signatures 24/7.
Our Signing API allows developers to get unlimited access to DeFi through low-level message and hash signing on Layer 1/2 blockchains and smart contracts.
Configure your wallets by implementing policy and permission based rules for employees allowing you to manage and limit payment amounts, frequencies and more.
We support 500+ assets
Crypto, STO, NFT, and more.
