What Is Multisig? · My Wallet

Multisig (multi-signature) is a wallet or vault setup where more than one key must approve a spend—so no single person can move funds alone.

Quick answer

A multisig wallet requires M-of-N signatures (for example 2-of-3) before a transaction broadcasts. It is common for teams, treasuries, and shared savings. Everyday personal use of My Wallet is typically single-signer self-custody: one seed you control. My Wallet has related—but different—tools like Multisend (batch TON transfers) and multiple wallets / subwallets—not the same as shared multisig approval. If you need true multisig policy, verify the product that implements it; do not assume every wallet is multisig.

How multisig works (concept)

A policy defines how many keys must sign (M) out of a set (N).
Participants hold separate keys or devices.
A proposed transaction collects signatures until the threshold is met.
Only then does the network accept the spend.

Setup	Meaning	Typical use
1-of-1	Classic personal wallet	Daily self-custody
2-of-3	Any two of three keys	Small team treasury
3-of-5	Broader committee	DAO / org funds

Multisig reduces single-key theft and insider solo drains. It also adds coordination cost: lost keys, slow approvals, and social disputes.

What multisig is not

Not app Face ID or a PIN — those unlock one device; they are not extra on-chain cosigners. See Two-factor authentication for crypto wallets.
Not Multisend — Multisend batches many TON transfers you authorize; it is still your signing model, not M-of-N cosigning.
Not “multiple wallets in the gallery” — separate accounts you switch between.
Not guaranteed safety — collusion, phishing of multiple signers, or bad policies still fail.

When people choose multisig

Company or DAO treasury
Shared family vault with clear rules
High-value cold storage with distributed key holders

When people usually skip it:

Solo daily spending
Fast Telegram / dApp motion
Situations where one reliable offline backup already matches the risk

How this relates to My Wallet

My Wallet is built as a non-custodial multichain wallet for everyday self-custody across seventeen networks, with Telegram Mini App access and clear signing prompts.

Related features (different jobs):

Import / manage multiple wallets and subwallets
Multisend for batch TON payouts (limits depend on wallet version)
Ledger import for hardware-assisted TON flows (see Hardware wallet integration explained)
Offline wallet creation for air-gapped style setups

This article does not claim a native M-of-N multisig product inside My Wallet. For team policies, evaluate dedicated multisig tooling on the networks you use, then keep day-to-day funds in a wallet you understand.

Practical security notes if you use multisig elsewhere

Document who holds which key and how to replace a lost signer.
Test a tiny transaction before depositing size.
Prefer hardware or well-separated devices for cosigners.
Beware social engineering aimed at several signers in the same week.
Never share seeds “so we can all recover the multisig”—that collapses the model.

FAQ

Is Multisend the same as multisig?

No. Multisend batches transfers you authorize. Multisig requires multiple independent approvals under an M-of-N policy.

Does biometrics make my wallet multisig?

No. Biometrics protect access to the app on one device. On-chain multisig needs separate signing keys under a threshold policy.

Should beginners start with multisig?

Usually not. Master seed backup, official downloads, and careful confirmations first. Add shared-signing setups when you truly need shared control.
