Python SDK

This SDK gives Python teams direct access to Dfns’ wallet, transaction, and signing infrastructure, without having to build or maintain custom integrations.

Much of today’s financial infrastructure already runs on Python: trading, treasury, settlement, risk, reconciliation, and automation. Until now, connecting these systems to secure wallet and signing infrastructure required a lot of glue code and operational work. The Python SDK removes that burden by exposing the full Dfns platform through a native, strongly typed Python interface, with authentication, request signing, and error handling built in.

The SDK implements Dfns’ complete authentication and request-signing model, so every call is authorized, auditable, and consistent. It also maps the platform into stable Python objects: wallets, assets, addresses, transactions, policies, signatures, approvals, and events. Your application works with real domain models instead of raw JSON and custom wrappers.

In practice, this lets Python services directly own critical asset workflows. Trading engines can create wallets and move funds. Treasury systems can build transactions and enforce policies. Operations systems can manage approvals, monitor signing, and react to on-chain activity. All within existing Python services, with fewer components, fewer failure points, and a simpler overall architecture.

The SDK is built for production workloads: long-running services, workers, schedulers, and high-throughput backends. It provides the same security and policy guarantees used by banks, fintechs, and asset managers running on Dfns today.

If you are building serious financial infrastructure in Python, this SDK is meant to be a core building block.
