Service
Most key losses we investigate were caused by a wallet setup that looked secure on paper. We help you design and operate one that is secure in practice.
What you get
A wallet architecture you understand, can defend in an audit, and your team can actually operate without making mistakes.
Scope
Number of signers, threshold, hardware vs MPC, key rotation policy, recovery paths, environment separation between deployer / treasury / operations / hot wallets. We design or review against your operational reality, not a generic template.
Written procedures for the things you'll actually do under pressure: signing a transaction, rotating a compromised key, onboarding a new signer, handling the loss of a hardware device, executing an emergency pause.
Multi-sig signer selection has security and governance implications. We help you reason about who signs, how many, what 'compromised signer' means, and how the threshold reflects your real trust model.
The signers we design wallets for need to know how to use them. We train your team on transaction simulation, signature reading, phishing patterns, and the social-engineering vectors that target multi-sig signers.
Deliverables
Timeline. 1–3 weeks for design and rollout, depending on team size.

Glossary
Multi-Sig (Multi-Signature)
A wallet that requires multiple signatures from separate keys to approve a transaction.
MPC Wallet
A wallet using multi-party computation to split a single key across multiple parties so it never exists in one place.
Safe (Gnosis Safe)
The leading multi-sig smart-contract wallet on EVM chains, used by most DAOs and protocol treasuries.
Key Management
The full lifecycle of cryptographic keys: generation, storage, use, rotation, and destruction.
