What is Dfns?
Dfns is a wallet-as-a-service and key management API that businesses use to create and control wallets across 100+ blockchains. Keys can run on MPC, HSMs, TEEs or BYOK, using its own MPC threshold signing protocols (CGGMP24, FROST, KU25). Plans start at $800 per year with no AUM or transaction fees.
How Dfns works
When you create a Dfns wallet, no complete private key is ever generated.
A threshold signature scheme creates key shares held on separate, independent signer servers, and a minimum number of shares must take part in each signing ceremony. The signer nodes run inside AWS Nitro Enclaves. On the default fully managed cloud, Dfns runs the signers, and there is no seed phrase or single secret to back up. You prove identity with passkeys or API keys, which cannot sign blockchain transactions themselves.
Every request passes a policy engine before signing, with address allow and deny lists, roles, permissions and approval rules. You can run wallets as org-managed, where your organization controls them through the API, or delegated, where your end users hold signing authority after they log in. Pro plans can host signers in your own cloud, and Enterprise adds on-premises deployment with bring-your-own-key, CloudHSM, HSM and offline signers.

Risks to know before using Dfns
- On the cloud model Dfns holds every key share, so your operations depend on its uptime; every plan includes a 99.95% uptime SLA and insurance covering crime, E&O and cyber.
- Delegated wallets give your end users signing authority, while org-managed wallets keep it with your organization, so pick the model before you build.
- Private key import and export is a Pro add-on and is not offered on Starter or Basic.
