Den’s Multi-Layer Security Wallet API and SDK provide programmatic access to accounts, policies, members, transactions, and more. Currently, we offer a TypeScript SDK for streamlined and secure development. Please contact our team to request SDKs in additional languages.

Core Concepts

Learn the foundational concepts behind the MLS Wallet API & SDK.

Quickstart
