The first choice for builders who value security

The orchestration layer your systems have been missing

Dfns brings structure, automation, and resilience to your transaction workflows across over 100 blockchains and 1,000+ tokens. Whether you're managing token transfers, staking operations, or large-scale treasury flows, our API ensures consistency, security, and control, no matter the asset or network.

Programmability

Design custom workflows with full control over when, how, and by whom transactions are approved. Use our policy engine and permissions system to codify your governance model and adapt to changing needs over time.

Efficiency

Optimize operations with automatic routing, cost-based path selection, and built-in integrations for native actions like staking or unwrapping. Minimize latency and manual work through API-first automation.

Reliability

Ensure execution under all conditions with transaction queuing, retries, and fallback strategies. Dfns prevents silent failures and guarantees visibility into each transaction’s lifecycle, from initiation to confirmation.

Build to catch what others let through

The only system that inspects 
your transactions before they hit the chain

Most wallets are designed to sign. Dfns is designed to protect. We help institutions prevent silent failures, bad calls, and governance gaps by deeply analyzing transactions before they’re broadcast. From ABI decoding to signature custody, every layer of the system is programmable, observable, and secure by default.

Clear signing

Transactions are parsed and made human-readable before signing, with full ABI decoding for smart contracts. You control what gets signed—and how.

Simulated before execution

All transactions can be simulated to detect errors, invalid calls, or high-risk outcomes before they reach the chain.

Retry mechanisms

Query, cancel, or override any pending transaction through programmable API calls and approval flows—before it becomes irreversible.

Bring-your-own-security

Use MPC or connect your AWS KMS, HSM, or enclave infrastructure to sign transactions while keeping custody and control.
