Assign or Modify permissions Permission

Cryptographically verify every intent, policy, and signature against a state you control. Deployed in your perimeter. No trust required.

Step 3/3

Create your Passkey

Passkeys replace passwords with a simpler, more secure way to sign in.

This option uses biometric verification (fingerprint or facial recognition) to confirm your identity before granting access.

Advanced Create Passkey Using a Hardware Key

This option secures your account using a security key from your password manager or a hardware key device.

Run keys across MPC, HSMs, TEEs, or BYOK models. DFNS supports production-grade protocols built for resilience, scale, and no single point of failure.

Developer First

The only wallet built for developers
from the ground up

One REST API, SDKs in TypeScript, Python, Go, Java, and more.
Runnable examples for every workflow you operate on- and off-chain.

Engineers built DFNS to fix the recurring failures of digital asset infrastructure—fragmented custody, manual ops, brittle integrations, security that won't bend to real workflows. All of it: API-exposed, policy-governed, production-grade.

Close to the metal

We built our key management, signing infrastructure, and attestation engine from scratch. Our own MPC protocols (CGGMP24, FROST, KU25), our own HSM connectors, our own TEE-backed integrity channels. End to end.

Scale for every size

The same API serves a founder shipping a sandbox prototype and a Tier-1 bank running production. We move at your speed and speak your language through every stage — from first call to your first million dollar transaction.
