Deploy safe web3 wallets
with peace of mind
Dfns enables applications and organizations to create, manage and embed wallets at scale using a versatile developer platform designed for digital asset security.
Secure, programmable wallets
designed for developers
Programmability
Our APIs and SDKs were built for wallet programmability and efficient implementations, enabling fast deployments and automation flows that reduce time-consuming development.
Security
Embed MPC cryptography to remove all single points of failure with sharded keys that periodically refresh in secure enclaves across a decentralized network of T3+/4 data centers.
Scalability
Create millions of wallets and manage peak hours without failing to assure 99.95% yearly availability rate thanks to our microservice-first architecture and cloud-based infrastructure.
Configure wallets exactly like you need them
We simplify blockchain key management so developers and users can interact with digital assets confidently. Dfns is a safety net offering protections against mistakes that could be irreparable.
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.

Infrastructure performance
Peak traffic handling, sub-second MPC signing,
and >99.95% annual uptime.
100+ supported blockchains and apps
From exchanges, staking platforms, tax management tools, KYT checks and more,
Dfns provides a suite of pre-built integrations to help developers scale from zero to one.
Build on ERC-4337 smart contracts with Dfns.
Use paymasters (gasless transactions) and bundlers (batch signing transactions) on Ethereum/EVMs in collaboration with industry standard smart contracts.
Send and receive crypto between any Dapp.
Don’t worry about creating silos—you’re not. Use our WalletConnect integration for direct calls to any protocol, or create EC-based signatures for custom payloads.
From ERC-721 to Ordinals, we support them all.
Dfns wallets serve various NFT verticals–ticketing, art, identity. Integrate our APIs to streamline NFT transfer management and data indexing across multiple chains.
Scale on a microservice-driven infrastructure ensuring rapid signing and no downtime.
Sphere's collaboration with Dfns improved our payment rails by providing robust security, near-perfect uptime and fast transaction processing. Dfns' commitment to innovation and reliability not only enhances our efficiency but also sets a new industry standard, making them a vital partner in our continued success.

The best wallet saves you–even from yourself
Dfns' risk model is grounded in the recognition that human errors are inevitable
Dual security approach
Per NIST recommendations, our solution separates applications from keys for easier, safer wallet management. In our model, two-factor authentication credentials unlock wallets while private keys are stored in a highly secure MPC network. This way, losing passkeys does not mean losing private keys.
Programmable governance
The most battle-tested, API-first policies and permissions enabling both transaction rule-setting (including variables like amounts, time, velocity, frequency, etc.) and role-based access controls.
Institutional key management
The most battle-tested, API-first policies and permissions enabling both transaction rule-setting (including variables like amounts, time, velocity, frequency, etc.) and role-based access controls.
Why MPC matters a lot
Multi-party computation (MPC) protocols pave the way for the next generation of secure and resilient wallet solutions as they are uniquely capable of decentralizing keys and ensuring recovery.
Zero trust, zero touch
Dfns combines defense in-depth with ZT security to eliminate single points of failure and ensure business continuity with multilayered protections and programmatic controls.
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 with EdDSA/Schnorr.
Stability
Dfns has built integrations with multiple blockchain RPC node-as-a-service providers (Infura, Alchemy, Ankr, etc.) to ensure high redundancy and automatic retargeting in case of failure.
Availability
Dfns' SLA ensures 99.95% availability, translating to a yearly downtime of 4 hours, 38 minutes. We aim for 99.995% availability levels as we upgrade to exclusive T4 data centers in the near future.
