Multi-sig wallet setup

A multi-sig (multi-signature) wallet is a wallet that requires several signatures to confirm a transaction under an M-of-N scheme: e.g. 2 of 3 or 3 of 5 key holders must approve an operation for it to go through. Unlike an ordinary wallet (one key = full control), multi-sig distributes control among several keys/people. Honestly about the real benefit, and this is the strong side: multi-sig is one of the few crypto applications that honestly increases security in the right scenarios. It removes the single point of failure: compromise or loss of one key does not lead to loss of funds, no single person can solely dispose of the treasury. For teams, DAO treasuries, joint funds and simply increased protection of large sums this is genuinely valuable. Honestly about 'it is still crypto': multi-sig does not cancel the fundamental properties of the blockchain. Transactions are still irreversible. And crucially: if enough keys are lost to not reach the required threshold (e.g. in a 2-of-3 scheme 2 keys are lost), the funds are locked irreversibly — no one will return them. That is, multi-sig protects against losing ONE key but adds the risk of managing SEVERAL. Honestly about usage complexity: multi-sig is harder than an ordinary wallet. Each transaction requires coordinating several signatories, which is slower and requires processes. For frequent operational transactions it is inconvenient; multi-sig is more for important/treasury operations. Honestly about the threshold choice, this is critical: the M-of-N scheme is a trade-off. Too high a threshold (e.g. 5 of 5) — a high risk of locking on losing one key. Too low (1 of 3) — almost no protection. An incorrectly chosen threshold either exposes funds to risk or threatens to lock them. We honestly select the threshold for your situation and risks. Honestly about smart-contract multi-sigs: many multi-sigs are implemented as smart-contracts — so contract risk (a bug) applies to them. We use proven solutions and/or review (1075). Honestly about the effect: for teams and treasuries it gives a real increase in security through distributing control, but at the cost of complexity and with honest crypto caveats. Honestly about access: several reliable key holders and storage discipline are needed. An important boundary: this is multi-sig; ordinary wallet — 1077; DAO treasury — 1080; contract audit — 1075. The base price starts from 80,000 ₽ (depends on the scheme and network).

• Funds/treasury are controlled by one key — a single point of failure.
• A team/DAO needs joint approval of operations, without sole control.
• You want multi-sig but the risk of locking on key loss is not accounted for.
• The signature threshold (M-of-N) is not chosen for the real risks.

• Multi-sig wallet setup under an M-of-N scheme (e.g. 2 of 3)
• An honest threshold choice for your risks (balance of protection/locking risk)
• Using proven multi-sig solutions and/or code-review (1075)
• Signatory coordination processes and secure key storage
• Honest boundaries (it is still crypto; irreversibility; losing the threshold of keys = irreversible locking; harder to use; not absolute security)
• Testnet testing
• Documentation and handover
• Review with you

• A multi-sig wallet without a single point of failure (for teams/treasuries)
• A threshold M-of-N chosen for risks (balance of protection and availability)
• An honest assessment: the real benefit versus the added complexity
• Honest boundaries (irreversibility; locking risk on key loss; complexity; not absolute security)

• We discuss key holders, the M-of-N scheme and risks
• We set up multi-sig (a proven solution/contract + review), test on testnet
• We establish processes and key storage, honestly set boundaries and hand over to you

• Does multi-sig make crypto storage absolutely secure?

  No, honestly: multi-sig is indeed one of the genuinely useful crypto applications, it removes the single point of failure (compromise of one key does not lead to loss of funds). But it is still crypto: transactions are irreversible, and if enough keys are lost to not reach the threshold, funds are locked irreversibly. Multi-sig removes one risk at the cost of adding another (managing several keys). It does not give absolute security — we are honest about this.

• Which signature threshold to choose — higher for reliability?

  Not necessarily, it is a trade-off, honestly: too high a threshold (e.g. 5 of 5) — a high risk of locking funds on losing one key. Too low (1 of 3) — almost no protection. A wrong threshold either exposes funds to risk or threatens locking. We honestly select M-of-N for your situation, the number of reliable holders and risks, rather than setting 'higher' blindly.

• Is multi-sig harder to use than an ordinary wallet?

  Yes, honestly: each transaction requires coordinating several signatories — this is slower and requires processes. For frequent operational transactions it is inconvenient; multi-sig is more for important/treasury operations. Plus many multi-sigs are smart-contracts to which contract risk applies (we use proven solutions and/or review — 1075). We honestly build in this complexity rather than pass multi-sig off as 'just as simple but more secure'.
