About Den
Den is a self-custody wallet and treasury operations platform for teams, with accounts built on Safe smart accounts for multisig approvals, bulk transfers, swaps and bridging, calls to arbitrary contracts, and payouts from crypto straight to bank accounts. Signers often cannot see what a pending transaction will do, and approvals scatter across chat tools. Den enforces policy at three layers: local checks in the signing client, an off-chain Guardian, and on-chain contract limits, with simulation and decoding that show fund flows before signing.
The line also covers wallet-as-a-service, an auto-generated ledger and financial statements, and bots that chase signers over Discord, Telegram and Slack, serving DAOs, protocol treasuries and conventional firms holding on-chain funds. Unlike MPC wallets that split keys, Den keeps the full key under multisig and policy control, deploys across more than ten EVM networks, and can run in a customer's own cloud or data center for residency requirements.
In January 2023, Den launched as a self-custody multisig wallet for DAOs and on-chain organizations, built on Safe contracts, supporting multiple chains and complex transaction parsing, with APIs and SDKs.
On February 22, 2023, Den announced a $2.8M seed round led by IDEO CoLab Ventures, with Gnosis participating; co-founders are Jonah Erlich and Ittai Svidler.
As of February 22, 2023, about one month after launch, Den had secured over $130M in assets and processed over $15M in transactions, and supported a multisig policy engine.
On April 10, 2024, Den joined Zeeve's Rollups-as-a-Service network as an integration partner to deploy Safe multisig infrastructure to new chains, expanding its multi-chain ecosystem.
In 2026 Den moved beyond multisig coordination into an enterprise wallet platform. Its multi-layer wallet checks transaction policy independently at three points, the signing client, a network-isolated Guardian service and the onchain contract, so no single compromise can move funds; contracts are open source, audited by Certora and yAudit, and the company holds a SOC 2 Type II report.
Horizen Chain adopted Den as its multisig interface during the year, letting users create or import Safes, simulate transaction effects and batch execution on that network. The platform reports more than 400 teams and over USD 5 billion transacted, and offers Wallet-as-a-Service as an embedded option for stablecoin apps and AI agents, with deployment in Den's cloud, the customer's cloud or on-premise. The team reported a 33% month-on-month rise in site traffic in May 2026, with enterprise customers spanning DAOs, market makers and stablecoin issuers on a subscription plus usage model. Contracts passed independent audits by Certora and yAudit.
Future strategy and roadmap: Den will keep adding supported EVM networks and policy templates, deepen accounting and approval automation, and treat self-hosted deployment as the primary delivery model for institutional clients.
