Every organization holding digital assets faces the same problem: who controls the money, and how do you keep it secure? Send Safe answers that question with a fully onchain, non-custodial multisig built for how teams actually operate - from a 2-of-3 founding setup to institutional 4-of-7 cold storage structures, all without seed phrases or third-party custodians.

Every organization that holds digital assets eventually runs into the same question:

Who controls the money, and how do you keep it secure?

In traditional finance, this is solved through layers of approvals, bank policies, and operational controls. But those systems are slow, opaque, and dependent on third parties.

Onchain, the responsibility shifts to you.

That is where Send Safe comes in.

Send Safe is a fully onchain, non-custodial multisig designed for teams and institutions that need structured control over their assets, without sacrificing speed or security.

Built for How Teams Actually Operate

Different organizations require different levels of control. A small founding team does not operate the same way as a DAO or an institutional fund.

Send Safe is designed to scale with that reality.

The Small Team (2-of-3)

Early-stage companies need flexibility, but they also need protection.

A typical setup is a 3-person founding team managing operational funds, contractor payments, and reserves. In this environment, no single individual should have unilateral control over the treasury.

A 2-of-3 multisig solves this cleanly. Any two founders can approve a transaction, ensuring continuity if one person is unavailable, while still preventing any single point of failure.

This is the simplest starting point: separation of control without operational friction.

The Growing Company (3-of-5)

As a company scales, so does the importance of governance.

With additional stakeholders such as a CFO, CEO, and board members, treasury decisions often require broader oversight, especially for large transfers.

A 3-of-5 multisig distributes authority across key decision-makers. Routine transactions can move efficiently, while larger movements require quorum.

This structure mirrors traditional corporate treasury controls, but now it is onchain, fully auditable, and not constrained by banking hours or intermediaries.

The Fund or DAO

Funds and DAOs operate in more complex environments.

They manage capital on behalf of others, operate across jurisdictions, and often require transparency without exposing sensitive information.

Send Safe supports this with flexible configurations tailored to governance requirements.

Teams can define custom approval thresholds, attach transaction memos for auditability, and share approval links so signers across time zones can review and authorize asynchronously.

At the same time, Send Safe’s privacy model ensures that participants only see what they need to approve. Sensitive details remain compartmentalized, even within the organization.

Custodial Operations

For entities managing assets on behalf of clients, LPs, or protocols, the requirements are stricter.

Send Safe enables operational segregation by allowing teams to create separate Safes for different purposes.

A common structure includes:

  • Hot wallets for day-to-day liquidity with lower approval thresholds

  • Cold storage with higher thresholds (e.g., 4-of-7) for long-term reserves

All of this remains fully non-custodial. There is no reliance on third parties holding keys or enforcing policies.

You define your access model. You control the funds.

Getting Started

Setting up a Safe is straightforward:

  1. Go to send.cantonwallet.com

  2. Create your Safe and define your approval threshold (e.g., 2-of-3)

  3. Add signers using their wallet addresses

  4. Fund the Safe with USDCx or other Canton-native assets

  5. Start operating: create transactions, share approval links, and collect approvals

There are no seed phrases to manage.

Authentication is handled through passkeys, using biometrics or device-based security.

Everything is fully onchain.

Why Canton

Canton Network was designed for institutional-grade finance.

It offers privacy by design, regulatory compatibility, and interoperability between participants—all critical requirements for serious capital.

Send Safe brings that infrastructure into a usable interface.

Instead of building complex treasury systems from scratch, teams can adopt a structure that is already aligned with how modern organizations manage funds.

A New Standard for Treasury

As more capital moves onchain, the expectations around control and security are changing.

It is no longer enough to simply hold assets.

Teams need defined access policies, clear approval structures, and systems that reflect how they actually operate.

Send Safe is built for that shift.
