The first choice for builders who value security

Secure, programmable wallets designed for developers

Programmability

Our APIs and SDKs were built for wallet programmability and efficient implementations, enabling fast deployments and automations to reduce development time.

Security

Lean on advanced cryptography to remove single points of failure with keys that periodically refresh in enclaves across a distributed network of top tier data centers.

Scalability

Create millions of wallets and manage peak hours without failing to assure best-in-class availability rates thanks to our microservice- and cloud-based infrastructure.

For custodial and non-custodial APPLICATION

Configure wallets exactly like you need them

Org-controlled wallets

Org-controlled wallets empower organizations with exclusive control over signing processes and transaction approvals. By generating the necessary passkey-based credentials for the Dfns API internally, your organization becomes the sole custodian of all assets in these wallets.

User-controlled wallets

User-controlled wallets enable companies to act as pass-through applications, allowing end-users to maintain control over their wallets and assets. This non-custodial approach bypasses the need for third-party custodians or intermediaries in interactions with Dfns’ decentralized KMS.

MPC is a revolution for DIGITAL ASSET security

The best wallet saves you–even from yourself

Dfns' risk model is grounded in the recognition that human errors are inevitable.

Dfns aims to simplify secure key management, allowing developers and users to make errors without causing irreparable damage. Our solution replaces complex private keys with API keys, separating governance from security for easier, safer wallet management. Losing passkeys does not mean losing private keys anymore.

Programmatic governance

Battle-tested APIs exposing policies and permissions that enable transaction rules (including data like “amount”, “time”, “frequency”) and role-based access controls.

Institutional KMS

Dfns protects private keys in peer networks but also supports hybrid and on-prem deployments of MPC key shares across different cloud environments or BYOD and HSM.

MPC matters

Multi-party computation (MPC) protocols are shaping the future of secure wallets by decentralizing private keys and providing unmatched recovery options.

Zero trust, zero touch

Dfns combines defense in-depth with zero trust security to eliminate single points of failure, avoid business disruptions and swiftly recover from any attack.

Don’t trade off security FOR performance

Scale with the most reliable MPC wallets

Speed

Who said MPC was slow? Dfns can generate up to 10 ECDSA signatures and hundreds of keys per second using the most cutting-edge MPC protocols. It’s even faster on curves like EdDSA.

Stability

Dfns has built integrations with multiple blockchain RPC node-as-a-service providers (Infura, Alchemy, etc.) to ensure high redundancy and automatic retargeting in case of failure.

Availability

Dfns' SLA ensures 99.95% availability, translating to yearly downtime of just 4 hours, 38 minutes. We aim for 99.995% availability as we upgrade to T4-only data centers over time.
