Den is a multi-signature wallet tool built on Safe contracts, designed to address pain points in transaction coordination, understanding, and creation for multi-sig teams. It offers batch transaction creation, parsing of complex transactions, simulation execution (powered by Tenderly), and transaction descriptions to help users clearly grasp each operation. Den also supports automatic reminders to unsigned members via Discord, Telegram, and SMS bots, along with signer activity statistics. On the security front, Den employs a multi-layered strategy: mobile and SDK signing, a network-isolated Guardian co-signer, and on-chain smart contract verification, without modifying the original Safe contracts. Den offers three deployment modes: cloud-hosted, private cloud, and on-premise. suitable for DAOs, enterprises, and digital asset issuers.

About Den
Den is a self-custodial multi-signature wallet platform built on Safe Contracts, designed for onchain teams and DAOs. Its core business is to simplify the creation, signing, and execution of multi-sig transactions through a web interface, SDK, and notification bots for Discord, Telegram, and SMS.
Its key differentiator is a policy-based control layer: instead of requiring all signers to manually review every transaction, teams can define rules (e.g., low-risk transfers auto-execute with one signature, high-value ones need M-of-N approval). It also offers transaction parsing and simulation (powered by Tenderly) to make complex contract calls human-readable, plus batch transaction creation to reduce signing fatigue. Deployment options include cloud, self-hosted cloud, and on-premise, all using the same audited contracts.
Market pain points addressed: traditional multisigs are slow (signers lose hardware wallets, forget to sign), opaque (raw calldata is hard to audit), and risky (blind signing, man-in-the-middle attacks). Den solves these by automating reminders, translating transactions into plain language, and enforcing policies across multiple independent layers—each signer holds their own key, and no single server compromise can drain funds.
Recent development (Feb–Aug 2026): Den crossed $10B in cumulative transaction volume in May 2026. It launched cross-chain bridging (Sep 2024) and native token swaps (Apr 2024), expanding to Ethereum, Arbitrum, and Gnosis Chain, with more networks in beta. The team has been actively hiring engineers to scale infrastructure. No major security incidents or regulatory actions were reported in the past two years.
In the past six months, Den has made significant progress. In May 2026, Den announced that its cumulative transaction volume surpassed $10 billion, and it is now sprinting towards the $100 billion target. To support this growth, the company is hiring full-stack engineers to help major global organizations securely manage stablecoins and cryptocurrencies.
Regarding future development, Den is about to launch a premium tier that will provide organization management features, including grouping related Safes, granting non-signers permission to view and edit off-chain data, end-to-end bookkeeping, data export and synchronization to accounting software such as Quickbooks, as well as dynamic financial insights charts and reports. These features are currently in limited early access, and users can apply by booking a demo.
Den's core is a self-custodial multi-signature wallet built on Safe Contracts, designed to solve the challenges of coordination, understanding, and creation in multi-signature transactions.
