Application Review & Advisory for an MPC-TSS Crypto Startup

The Challenge

A deep-tech startup specialising in MPC-based threshold signature schemes and privacy-preserving computation was preparing for enterprise client partnerships and investor due diligence. Their core cryptographic protocols were peer-reviewed and technically sound, but the surrounding application layer, engineering processes, and developer-facing documentation had not been reviewed from an external adopter's perspective. They needed an independent assessment to identify blind spots before they became blockers in enterprise sales cycles.

Our Approach

We conducted a structured review across three dimensions: the application layer built on top of the MPC-TSS libraries (SDK integration patterns, API design, error handling), engineering and operational processes (release management, versioning, incident response readiness), and technical documentation (developer guides, integration references, protocol explanations). Each finding was assessed for its potential impact on enterprise adoption, developer experience, and operational reliability — not just technical correctness.

What We Built

A detailed advisory report structured around the three review dimensions. Application layer findings covered SDK API surface inconsistencies across mobile platforms (iOS/Android), incomplete error propagation from the MPC protocol layer to the application layer, and key lifecycle management gaps in multi-party signing flows. Process findings addressed release versioning discipline, lack of integration test coverage for cross-platform threshold signature scenarios, and absence of runbooks for key refresh and proactive secret rotation. Documentation findings identified gaps in protocol explanation depth, missing developer quickstart paths for wallet and custodian integration scenarios, and terminology inconsistencies between research papers and integration guides. All findings included prioritised recommendations and concrete next steps.

Results & Impact

The client used the report to drive a targeted improvement sprint ahead of enterprise partnership discussions. Documentation quality improvements reduced integration friction for new developer partners. SDK consistency fixes identified in the review were incorporated into the next library release. The structured process recommendations provided a foundation for more predictable and auditable release cycles — directly relevant for regulated financial institution clients evaluating the platform.
