Wallet & Treasury Security
We engineer institutional-grade multi-signature governance architectures, Multi-Party Computation (MPC) signing enclaves, Hardware Security Module (HSM) key management, and timelocked spending policies. We eliminate single-point-of-failure private key risks to ensure programmatic, auditable custody across Solana and EVM treasuries.

How It Works
Custody Modeling & Risk Profiling
We assess your protocol's capital velocity, signer distribution, governance tiers, and threat models to define optimal threshold policies and timelock delays.
Multi-Sig & MPC Policy Configuration
We deploy multi-signature governance vaults, configure M-of-N threshold rules, and establish cryptographic MPC key generation ceremonies.
Hardware Enclave & RBAC Integration
We integrate Hardware Security Modules (HSM) and cloud enclaves, establishing strict Role-Based Access Control (RBAC) for all signing operations[cite: 1].
Timelock Gating & Spending Limits
We deploy on-chain spending limiters, destination whitelists, and emergency pause circuit breakers to protect reserves from unauthorized drainage.
Mainnet Execution & Continuous Surveillance
We execute the secure treasury asset migration, verify on-chain state invariants, and connect 24/7 telemetry monitoring for all signer activities.

Case Studies
Multi-Sig Treasury Migration for $45M DeFi Protocol
Architected and executed the non-custodial treasury migration of a Solana DeFi lending protocol to Squads Protocol. Implemented a 4-of-7 multi-sig threshold with a 48-hour timelock vault, securing $45M in reserve assets against insider collusion.
Zero-Trust MPC Enclave for High-Frequency Desk
Integrated an AWS Nitro Enclave and MPC signing pipeline for an automated arbitrage trading desk. Enabled programmatic transaction signing at sub-millisecond speeds while ensuring private key material never existed in plaintext memory.
What Our Clients Say
"Zanvexis designed a treasury governance architecture that gave our DAO absolute security without slowing down routine operations. The multi-sig timelock system eliminated all insider risk."
"Their MPC enclave setup allowed our high-frequency bots to sign hundreds of transactions per minute without exposing private keys to our application servers."
Frequently Asked Questions
QWhy is a multi-signature wallet superior to a standard hardware wallet for treasury management?
A standard hardware wallet still relies on a single private key; if that device is lost, stolen, or coerced, all funds can be drained instantly. Multi-signature wallets distribute authorization across multiple independent parties (e.g., 4-of-7), requiring cryptographic consensus before any funds can move.
QHow do timelock vaults protect protocol treasuries from malicious governance takeovers?
Timelocks enforce an unbypassable delay (e.g., 24 to 72 hours) between the moment a multi-sig proposal is approved and when it actually executes on-chain. This gives the community, liquidity providers, and security teams time to inspect the transaction, detect malicious changes, and exercise veto or exit mechanisms.
QWhat is Multi-Party Computation (MPC) and how does it differ from multi-sig?
Multi-sig operates on-chain via smart contracts that require multiple distinct signatures. MPC operates off-chain at the cryptographic level: a single private key is mathematically split into secret shares among multiple computers that collaboratively sign transactions without ever reconstructing the full key.
QCan programmatic spending limits be enforced for automated trading bots and microservices?
Yes. We configure smart contract spending controllers and session key policies that allow automated bots to spend up to a strictly defined dollar or token cap per day while preventing unauthorized transfers outside pre-whitelisted destination contracts.
